Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high polymer bandages and splints are used for fixation, then strength and light weight are improved, but ease of operation deteriorates due to difficulty in wrapping around injured limbs
Solution Approach 1:
The splint is divided into multiple detachable plates that can be separately positioned and fixed around the injured limb. This segmentation allows the splint to be easily assembled and adjusted without requiring complex wrapping operations, while still providing strong fixation when assembled.
Solution Approach 2:
The splint incorporates adjustable components including ropes and fastening devices that allow dynamic adjustment of the splint's tightness and positioning. This enables the splint to adapt to different limb sizes and injury locations, improving ease of operation while maintaining fixation strength.
2Device complexity
If traditional fixation methods are used, then simplicity is maintained, but productivity deteriorates due to increased workload and time consumption
Solution Approach 1:
The splint plates are pre-configured with connection holes, ropes, and fastening mechanisms that enable quick assembly. The preliminary preparation of these components allows medical staff to rapidly apply the splint without time-consuming wrapping or complex assembly procedures, thereby improving productivity while maintaining operational simplicity.
3Device complexity
If manual tightening is used, then device complexity is reduced, but reliability deteriorates due to loosening and displacement during use
Solution Approach 1:
The splint incorporates tension detection circuits that provide feedback on the tightness of the fixation. This feedback mechanism allows the system to monitor whether the splint has become loose or displaced, enabling timely adjustment to maintain reliable fixation without requiring complex active control systems.
4Strength
If tight fixation is applied, then fixation strength is improved, but object-affected harmful factors increase due to potential skin injury and discomfort
Solution Approach 1:
The splint allows adjustment of fixation parameters including tightness and positioning through its adjustable ropes and fastening devices. This enables optimization of the fixation strength to the minimum necessary level, providing adequate immobilization while reducing the risk of skin injury and discomfort associated with excessive tightness.
