Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cooling temperature is set only on the basis of body temperature of users, then the cooling system can be simplified, but the adaptability to external weather conditions deteriorates
Solution Approach 1:
The cooling control system is designed to perform multiple functions: it monitors both body temperature via temperature collector and external weather conditions via communication module, then integrates both data sources to comprehensively control the cooling units. This multi-functional approach resolves the contradiction by maintaining system adaptability while managing complexity through integrated control logic.
Solution Approach 2:
The system implements feedback control by continuously monitoring body temperature through temperature collector and weather conditions through communication module, then using this feedback information to dynamically adjust cooling unit operation. This feedback mechanism enables the system to adapt to changing conditions while maintaining reasonable control complexity through automated regulation.
2Reliability
If cooling members are made integrated and fixed, then the cooling effectiveness is improved, but the convenience for washing and maintenance deteriorates
Solution Approach 1:
The cooling system is segmented into detachable components: cooling units with cooling members can be separated from the main clothing body. This segmentation allows the cooling members to maintain their integrated structure for cooling effectiveness while enabling easy removal for washing and maintenance, thus resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
The system transitions from a fixed integrated structure to a dynamic detachable structure. The cooling units can be attached or detached from the clothing body as needed, providing both the cooling effectiveness of an integrated system and the washing convenience of separable components through this dynamic configuration capability.
3Stability of the object's composition
If cooling members are made rigid for structural stability, then the cooling area coverage is improved, but the flexibility and comfort for user activity deteriorates
Solution Approach 1:
The cooling members are constructed using flexible materials such as flexible printed circuit boards and flexible heat dissipation members instead of rigid structures. This flexible construction maintains structural stability for cooling effectiveness while allowing the cooling members to bend and conform to body movements, thus resolving the contradiction between structural stability and activity flexibility.
Solution Approach 2:
The system employs composite material construction combining flexible substrates with functional cooling elements. The flexible printed circuit boards and flexible heat dissipation members create a composite structure that provides both the structural stability needed for cooling performance and the flexibility required for user comfort during various activities.
