THE STORY of UPCHAIR 38°

UPCHAIR 38°

Prologue

As I approach my eightieth birthday in 2025, I reflect on the decades spent hand in hand with my beloved wife, sharing a life filled with stability and joy. Unfortunately, five years ago, she was diagnosed with Alzheimer's disease her condition that not only robbed of her cognitive abilities but also stripped away her capacity for movement and speech. Despite the attentive care of three dedicated nursing aides, the weight of responsibility still rests heavily on my shoulders.
Each month, we make two trips to the hospital for body check-up and evaluations, participate in physical therapy sessions twice weekly, and attend cognitive enhancement courses offered by our nearly community center. I am acutely aware that for those who have lost complete autonomy, the likelihood of improvement from these measures is minimal. However, as her lifelong lover and guardian, I remain steadfast in my duty to care for her. I love her deeply and cherish the more than half century that we've spent together. This commitment is not only my obligation as her husband but also a profound expression of the bond we've forged over the years.

Section 1: The Revelation of an Accidental Fall
It was an ordinary afternoon on a certain day in 2020. As usual, I went to the supermarket to buy daily necessities. However, fate took a subtle turn at that moment—a careless misstep caused me to fall heavily onto the hard concrete floor. A sharp, overwhelming pain surged through my body like a tidal wave, instantly plunging me into an abyss of agony.
Realizing the seriousness of the situation, I rushed to the hospital for a thorough examination. After X-RAY, CT SCAN and MRI Tests the doctor informed me that there were no fractures and the injury was not severe. I was prescribed some painkillers and back home. Yet, once I returned, the pain did not subside as expected. Instead, it grew more intense, becoming an unbearable torment. For over 4 months time, I lived each day in the company of pain, and the effect of the medication gradually diminished, as if reminding me of life's fragility and unpredictability, which often arrives without warning.

Section 2: Awakening in the Midst of Suffering
What were once effortless daily movements now became daunting challenges I had to face every day. Every time I tried to rise from my bed or a chair, it was a battle-both physically and mentally. I had to grip the edge of the bed or the armrest tightly, summoning all my strength just to stand up.
This pain not only tormented my body but also deeply touched my soul. Yet, it was during these long, arduous hundred days that I gradually came to realize: pain is not the end, but rather the beginning of renewal. Each struggle and each act of perseverance became a source of inner strength, allowing me to understand more profoundly the resilience and meaning of life
Eventually, the pain began to fade, and in the process, I found a sense of inner peace and strength I had never known before.

Section 3: The Spark of Innovation
One afternoon, as sunlight filtered through the window, a sudden idea flashed through my mind: What if there were a chair whose seat cushion could automatically adjust its height and tilt?
Such a design would not only alleviate the discomfort of prolonged sitting but also provide an easier way for countless people to stand up effortlessly.
This concept was not just a reflection of my personal experience but also a pursuit of human-centered design. It made me realize that innovation is not something distant or unattainable; rather, it stems from careful observation and deep understanding of life.
Such a chair would be more than just a functional piece of furniture-it would be a gesture of respect and care for life itself. It could bring convenience and comfort to those with mobility challenges, the elderly to anyone seeking a more comfortable way of living. This idea ignited a sense of purpose within me. I came to understand that the meaning of life lies not only in self-fulfillment but also in creating value for others. Through this innovation, I hope to bring well-being to more people, making their lives better because of my efforts. This has become the direction I strive for and the most noble mission of my life.

Section 4: The Heavy Blow of My Wife's Illness
Just as I was gradually recovering from my own pain, fate tested me once again in a cruel way. I began to notice subtle changes in my wife, such changes that filled me with unease. Her memory was fading; she often couldn't recall what had just happened. Her emotions became unpredictable, swinging between anxiety and confusion. It was as if an invisible weight was pressing down on her, a tangled web of bewilderment and suffering that she could no longer bear.
Faced with this reality, I made the decision to take her to the hospital for a comprehensive examination and consulted a senior psychiatrist. Three days later, the doctor's diagnosis hit me like a sledgehammer—my wife was diagnosed with Alzheimer's disease. The news was a devastating blow to our entire family. What made it even more heartbreaking was that my wife was completely unaware of her condition. Her world was slowly being consumed by forgetfulness and chaos.
This diagnosis forced me to reflect deeply on her physical and mental state. I realized that her health was deteriorating at an irreversible pace, and even the simplest daily tasks were becoming increasingly difficult for her. As her husband, I felt the weight of responsibility pressing heavily on my shoulders. I knew I had to find a way to ensure that, even as she gradually lost herself, she could still retain her dignity and comfort.

Section 5: Crafting the Upchair A Second Inspiration
One day, I watched as my wife struggled to rise from her chair, relying entirely on her own strength gripping table edge to stand up. This scene struck me deeply, bringing back memories of my own painful experience when I was injured. In that moment, I realized I had to find a way to ease her difficulty in standing, to give her more independence and convenience in her daily life.
Inspired by this thought, I decided to take immediate action. My goal was to create a more comfortable and practical living aid for her, one that would allow her to participate in daily activities with as much ease as possible.
This was not only an act of care for her health but also a way to protect her dignity. Through this design, I hoped she could still feel the warmth from me, even as her world gradually faded into forgetfulness.
This idea was not just an expression of love for my wife but also a gesture of compassion for countless families facing similar challenges. I came to understand that the meaning of life lies not only in self-fulfillment but also in creating value for others. Through this innovation, I hoped to bring convenience and comfort to more people in need, making their lives better because of my efforts.

Section 6: Turning the Vision into Action

On the path to realizing this dream, I recalled three classmates from my university days. All of them had graduated from the Institute of Technology, specializing in mechanical engineering, and shared a strong passion for technology and innovation. One of them proposed an initial idea: using a “hydraulic” system to combine a hydraulic machine with a motion device, enabling the chair to adjustautomatically. However, after thorough research and discussion, we discovered that this approach had significant limitations.
Hydraulic systems were not only bulky and heavy but also costly. Moreover, their tendency to leak and difficulty in maintenance ultimately forced us to abandon this concept.

Despite this setback, the attempt taught me a valuable lesson: the road to innovation is inevitably paved with challenges, but every failure is a stepping stone toward success.
Each obstacle we encountered only strengthened my resolve to find a better solution, one that would truly make a difference in the lives of those who needed it most.

Section 7: Forming the Team

Although the initial attempt ended in failure, we were not disheartened. Instead, it strengthened our resolve to move forward. At the suggestion of one of my classmates, we decided to form a diverse team, bringing together talents from various fields. We invited two automation engineers, a furniture designer, and several experienced carpenters to join us. Each team member contributed their expertise, engaging in in-depth discussions and planning regarding material selection, aesthetic design, and overall style. We meticulously prepared the necessary tools, woods and fabrics, laying a solid foundation for the construction of the upchair. This process made me deeply appreciate that the power of teamwork far surpasses individual efforts, and the fusion of diverse perspectives and professional knowledge is the true source of innovation.

Section 8: The First Failure and Reflection
After extensive research and discussion, the engineers proposed a new solution based on a “direct-drive” mechanism, which could tilt the rear of the lifting cushion to 38 degrees, aligning with ergonomic principles to enhance the chair's functionality. However, during implementation, we encountered numerous challenges. Despite multiple attempts, we eventually completed the construction of the upchair. Yet, during the testing phase, a serious issue emerged: when a friend weighing over 100 kilograms used the chair, its load-bearing capacity proved insufficient, preventing the chair from lifting as smoothly as expected. This outcome fell far short of our expectations, leaving us deeply disappointed.

Nevertheless, this failure taught me an invaluable lesson: new invention is not achieved overnight but requires continuous trial and improvement. Each failure is a precious experience, offering us clearer insight into the essence of the problem and strengthening our determination to move toward our goal. We realized that only by learning from setbacks and accumulating wisdom through failure can we truly achieve breakthroughs and bring well being to more people.

Section 9: The Initial Success of the making of our Upchair

After carefully reflecting on the reasons for our previous failure, our engineers proposed a brand-new solution: adopting a ball screw mechanism paired with high-strength bearings to address the issues of jamming and deformation during the chair's lifting process.
After a series of rigorous tests, the new design delivered exhilarating results, our chair not only became more durable but also operated with exceptional smoothness, as if silently showcasing the power of technology. Every member of the team felt an immense sense of relief, as their long hours of hard work finally paid off at this moment. This success was not only a validation of our technical capabilities but also a boost to the team's morale. It reinforced our belief that perseverance can ultimately break through challenges and lead us to the dawn of success.

Section 10: The Upgrade and Refinement of the Upchair

The initial success did not make us complacent. Soon after, our engineers proposed further improvements: by introducing a stepper motor, that we achieved automated adjustment functionality for the chair. This enhancement not only increased the platform's stability but also incorporated an "auto-lock" feature, further enhancing user safety.
Additionally, we integrated a nitrogen hydraulic system and auxiliary support rods, ensuring smoother power distribution and quieter operation. Thanks to these innovations, the device's noise level was reduced by 80%, creating a serene and peaceful environment for users. Each improvement reflected our relentless pursuit of perfection and our deep commitment to addressing user needs. Every step forward was a testament to our dedication to creating a product that truly makes a difference in people's lives.

Section 11: The Revelation from Product Safety Testing

A few days later, during a gathering with friends, I mentioned to a senior orthopedic doctor about the chair that we were developing. He reminded me that products designed for the elderly must undergo rigorous testing by the "Hong Kong Standards and Testing Centre" before they can be brought to market. These tests include load-bearing assessments, fire safety evaluations, and electromagnetic interference tests, among others. This revelation deeply shook me, as I realized how little I had known about these stringent regulations. The safety of a product is not just about user experience. It is about the dignity of life and the responsibility we bear.
Without hesitation, I contacted the Center the very next day to arrange the necessary testing for our product. This process made me profoundly aware that innovation requires not only technological breakthroughs but also a strong sense of social responsibility.

Section 12: The Successful Completion of the Load-Bearing Test

The officer in charge at the Testing Center explained the testing process in detail: they would apply a pressure of up to 150 kilograms for 14 consecutive days to thoroughly evaluate the chair's load-bearing capacity and the stability of its legs. I had always been confident in the materials we chose—we used the most robust black walnut wood, whose natural strength and resilience were more than capable of withstanding such a rigorous test. True to expectations, after 14 days of continuous testing, the chair emerged unscathed, successfully passing the load-bearing test.
This outcome not only proved the precision of our material selection and the excellence of our craftsmanship but also deepened my understanding that only by approaching every detail with meticulous care can we achieve exceptional quality. This success was not only a validation of our technical capabilities but also a source of inspiration for the team's unwavering belief in our mission.

Section 13: The Successful Completion of Fire Safety Testing

After the successful completion of the load-bearing test, the officer informed us that the woods, leather, fabric and foam used in the chair would undergo a 10 days fire safety assessment. Additionally, they recommended that we hire a certified fire safety company to apply a fire-retardant coating. I readily accepted this suggestion, knowing full well that safety is the cornerstone of any product and cannot be compromised. After ten days of rigorous testing, our materials passed the fire safety evaluation without any issues. This result filled me with immense relief and reinforced my belief that only by prioritizing safety can we truly earn the trust and recognition of our users.

Section 14: Setbacks and Reflections in Electromagnetic Radiation Testing

However, the subsequent electromagnetic radiation test presented us with unprecedented challenges. The officer admitted that this assessment was particularly complex. Despite our engineers' best efforts to design a flawless product, the test results were disappointing, the chair's electromagnetic radiation exceeded the permissible limit by more than 20%, causing it to fail the test. This outcome left me deeply realized that there were still significant gaps in our design and safety standards.
This setback prompted profound reflection: on the path to innovation, failure and success often go hand in hand. Each failure is a valuable lesson, offering us clearer insight into the essence of the problem and strengthening our resolve to pursue excellence. We came to understand that only by learning from setbacks and accumulating wisdom through failure can we truly break through limitations and achieve higher goals. This experience reminded us that innovation is not just about celebrating successes but also about embracing the lessons hidden within every failure.

Section 15: The Second Failure in Electromagnetic Radiation Testing

In the second round of electromagnetic radiation testing, we faced yet another setback.
Despite the engineers' swift corrective actions—replacing certain components and substituting the stepper motor driver with a low-emission alternative to reduce electromagnetic radiation-the test results still exceeded the standard limit by 5%. The officer criticized our performance, leaving me deeply frustrated. However, this failure did not discourage me. Instead, it made me more acutely aware that challenges and difficulties are inevitable on the path of innovation.
Every setback is an opportunity for growth.
They allow us to see the essence of the problem more clearly and strengthen our resolve to pursue excellence. Each failure teaches us something invaluable, pushing us closer to our ultimate goal.

Section 16: Resignation of my Engineers

Just as we were working hard to adjust the design and prepare to face the challenge once more, our engineers on the team decided to leave. They admitted that they had lost confidence in the project's ability to pass the final test. Despite my best efforts to persuade them to stay, even offering salary increases, their decision remained firm. Facing their departure, I felt a sense of helplessness, Yet, deep inside, a voice reminded me: having invested so much time and effort, I could not give up now. I knew that only by persevering to the end could I stay true to my initial vision and fulfill my mission.
This moment tested not only the resilience of the project but also my own determination. It reinforced my belief that true innovation requires unwavering commitment, even in the face of adversity. The road ahead might be tough, but I was resolved to see it through, no matter the obstacles.
