Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The regular use of canes and crutches can cause discomfort and worsen pain for individuals with conditions like arthritis due to the lack of effective shock absorption and ergonomic design in existing walking aids.
Innovation Solution
A walking cane equipped with a linear adjustable hydraulic shock absorber end, featuring a threaded terminal end, a spring-loaded hydraulic shock absorber, and a mounting barrel, which allows for interchangeable shock absorbers with varying dampening strengths and strokes to customize user comfort and reduce impact shock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a cane or crutch is used for walking assistance, then mobility support is provided, but discomfort and pain worsen due to lack of shock absorption
Solution Approach 1:
The patent implements a hydraulic shock absorber system consisting of a piston, cylinder, and hydraulic fluid that absorbs impact shocks through fluid pressure changes. When the cane tip strikes the ground, the piston moves within the cylinder, compressing the hydraulic fluid to dampen the shock force, thereby reducing impact transmission to the user's hand and arm while maintaining structural support functionality
Solution Approach 2:
The patent employs a spring-loaded mechanism that changes the mechanical parameters of the shock absorber system. The spring provides a variable resistance force that changes with compression, allowing the system to adapt to different impact magnitudes. This parameter change enables the shock absorber to provide optimal cushioning across various walking conditions while maintaining stability
2Object-affected harmful factors
If a fixed shock absorber is installed in the cane, then shock absorption is provided, but adaptability to different user needs is reduced
Solution Approach 1:
The patent implements an adjustable shock absorber system where the piston rod can be positioned at multiple fixed lengths along the cylinder. This dynamic configuration allows users to adjust the shock absorption characteristics by selecting different piston rod extensions, thereby adapting the device to individual user requirements for shock mitigation and cane length
Solution Approach 2:
The shock absorber system is divided into separable components including the piston, cylinder, and piston rod assembly that can be independently adjusted or replaced. The threaded connection mechanism allows for discrete adjustment of the piston rod position, enabling users to segment the adjustment process into specific, manageable increments rather than continuous variation
