Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If commercial neck protection devices use comfortable materials, then wearing comfort is improved, but firmness and stability deteriorate
Solution Approach 1:
The neck protection device is divided into multiple independent components: a front collar portion, a rear collar portion, and a support sheet. Each component can be independently adjusted and positioned, allowing the device to maintain comfort through material selection while achieving stability through the segmented structural configuration and adjustment mechanisms.
2Device complexity
If a fixed support sheet is used, then structural simplicity is improved, but adaptability to different neck lengths deteriorates
Solution Approach 1:
The support sheet is designed with dynamic adjustment capabilities through multiple openings and positioning members that allow it to be repositioned along the rear collar portion. This enables the device to adapt to different neck lengths and user requirements while maintaining a relatively simple overall structure.
3Reliability
If the support sheet is fixed in position, then stability is improved, but adjustability for different users deteriorates
Solution Approach 1:
The positioning member can be moved between different openings in the rear collar portion, allowing the support sheet to be adjusted to various positions. Once positioned, the positioning member secures the support sheet in place, providing stability. This dynamic adjustment mechanism enables the device to accommodate different users and neck lengths while maintaining stability during use.
