Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flexible plate material with spiral spring is used for the compressive chest, then the chest compression function is achieved, but the manikin becomes non-stackable and occupies significant storage space
Solution Approach 1:
The compression mechanism is divided into modular components: a compression plate with integrated curved support structures, hinged supports, and sliding supports. This segmentation allows the compression system to be collapsed into a compact configuration for stacking while maintaining full functionality during use.
Solution Approach 2:
The compression plate and support structures are designed to nest within each other during stacking. The hinged supports fold inward, and the sliding supports retract, allowing multiple manikins to be stacked vertically in a space-efficient manner while preserving the compression capability.
2Volume of moving object
If stackable design is implemented, then storage space is reduced, but assembly time increases significantly
Solution Approach 1:
The hinged support and sliding support are combined into an integrated assembly that moves as a unit during both stacking and assembly operations. This merging reduces the number of discrete assembly steps while enabling compact stacking configuration.
Solution Approach 2:
The hinged and sliding supports provide dynamic movement capability, allowing the compression plate to transition between extended (operational) and retracted (stacking) positions. This dynamic design enables quick configuration changes without time-consuming assembly steps.
3Stability of the object's composition
If a non-flexible chest plate with curved lower plate face is used, then the shape stability is improved, but the compression mechanism complexity increases
Solution Approach 1:
The curved lower plate face of the compression plate is designed with a specific radius of curvature that provides stable geometric engagement with the hinged and sliding supports. This curvature enables the compression mechanism to maintain stable contact points during compression while keeping the overall design relatively simple.
