Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If elastic belts are used for shock absorption, then shock absorption effect is improved, but the degree of shock absorption cannot be adjusted
Solution Approach 1:
The patent transforms the static elastic belt into a dynamic adjustable system by introducing an elastic brace with adjustable secondary braces. Users can modify the length and elasticity of the secondary braces to change the shock absorption degree according to different carrying conditions, body types, and movement ranges, thereby achieving both effective shock absorption and adaptability.
Solution Approach 2:
The patent enables parameter adjustment by allowing users to change the length of the secondary braces and the position of the elastic band connection points. This changes the physical parameters of the shock absorption system (elasticity, length, tension), allowing the same elastic belt structure to provide different levels of shock absorption for different scenarios.
2Device complexity
If fixed braces are used, then structure is simple, but back support is insufficient and comfort is reduced
Solution Approach 1:
The patent divides the brace into multiple segments: main braces, secondary braces, and adjustable elastic bands. This segmentation allows each part to perform its specific function - the main braces provide structural support, while the secondary braces and elastic bands provide adjustable cushioning and back support, improving comfort without significantly complicating the overall structure.
Solution Approach 2:
The patent introduces adjustable elements into the brace structure, transforming it from a completely fixed structure to a semi-dynamic one. The secondary braces can be adjusted in length and position, allowing the brace to adapt to different back shapes and carrying conditions, thereby improving back support and comfort.
3Ease of manufacture
If non-adjustable braces are used, then manufacturing is simple, but shock absorption effect is greatly reduced when movement range changes
Solution Approach 1:
The patent incorporates adjustable secondary braces that can be modified by users according to their movement range and carrying conditions. This allows the shock absorption characteristics to be optimized for different scenarios without requiring multiple different brace designs, balancing manufacturing simplicity with adaptability.
Solution Approach 2:
The adjustable brace design serves multiple functions: it provides shock absorption for different movement ranges, adapts to different body types, and can be configured for various carrying loads. This multi-functionality is achieved within a relatively simple manufacturing framework by using standardized components with adjustable connections.
