Design briefing
Project Overview With the intensification of global population aging, the number of elderly people continues to grow, and the demand for assistive devices is also increasing. The market potential for standing canes is enormous, especially for the elderly who require assistance. The rapid development of intelligent technology provides the possibility for the upgrade of canes. This project is a more stable, safe, and convenient cane designed to support both hands when grandparents stand up while sitting, with a four legged structure at the bottom. Project background My grandfather is 94 years old, quite old. My grandmother passed away a long time ago, and my grandfather lives alone. He likes to live in his old house because there are his old friends nearby, so he doesn't have to live in high-rise buildings and it's very convenient to go out. Because he is older and has difficulty with his legs, his neighbors and old friends often come to his house to chat and have tea with him. Our house is very close to my grandfather's house, it only takes 4 minutes to ride a bike. My mother goes to my grandfather's house every day to visit him, chat with him, or bring some homemade dumplings, buns, etc.Grandfather's overall physical condition is good, and he is able to cook simple meals, boil water, and occasionally walk a short distance out to buy a small amount of food. But one of his knees often hurts, to the point where the leg is deformed and unable to walk normally, requiring the use of crutches. His crutch was originally made of simple wooden material, and later used aluminum alloy material. But they all have no extra functions or structures. When he sits under most chairs, the crutch armrest is located at the height of his chest. When standing up, he needs to press down on the armrest harder, and there is only one armrest. He often stands up with the other hand supporting nearby objects. In addition, the bottom of his cane only has one fulcrum, and when he presses down forcefully, the cane often becomes unstable and tilts, which is very dangerous.Here are photos of my grandfather's daily life. The first one is a photo of my grandfather and my sister's child, two adorable people who are 93 years apart in age. The second photo is of my grandfather on his birthday. The third photo is of my grandfather resting in the yard. Preference My grandfather likes dark colors, such as black, dark blue, and gray. Most of his clothes are also of this color, and there are not many patterns, which are relatively simple. He prefers aluminum alloy crutches because he needs them for a long time, and aluminum alloy crutches are lighter.Sometimes there may be situations where there is no lighting, the environment is relatively dark, and coupled with his advanced age, his vision deteriorates, making it difficult for him to see the road clearly. A cane is crucial for a grandfather who…
