Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional work steps like soldering or welding are used to connect electrical connection elements to the textile, then the electrical connection is reliable, but the manufacturing process becomes complex and time-consuming
Solution Approach 1:
The connection elements are pre-configured with elastic prestress during manufacturing, so that when the component is attached to the textile, the electrical contact is automatically established without requiring additional soldering or welding operations. The elastic element is already positioned to apply force in the correct direction upon assembly.
Solution Approach 2:
The elastic connection elements automatically establish and maintain electrical contact with the conductive regions of the textile through their inherent elastic prestress. The system serves itself by using the elastic recovery force to ensure continuous contact, eliminating the need for external soldering or welding processes.
2Reliability
If traditional connection methods are used, then electrical contact can be achieved, but the process requires additional work steps and is not adaptable to diverse applications
Solution Approach 1:
The component design with elastic connection elements can be universally applied to various textiles and functional elements with different conductive region configurations. The same basic component structure works for different applications (lighting, sensing, heating) without requiring application-specific connection methods, as the elastic elements can adapt to different positions and orientations of conductive regions.
Solution Approach 2:
The elastic connection elements provide dynamic adaptation to tolerances and variations in the positioning of conductive regions. The elastic prestress allows the connection elements to move within certain limits to maintain contact, making the system adaptable to diverse applications where precise positioning may vary.
3Ease of manufacture
If connection elements are designed to form electrical connection through force-fitting, then no additional work steps are required, but the connection must accommodate tolerances in the arrangement of conductive regions
Solution Approach 1:
The elastic elements change their physical state (deformation) in response to tolerances and positioning variations. By utilizing elastic deformation, the connection elements can accommodate certain ranges of positioning errors while still maintaining electrical contact, thus accommodating manufacturing tolerances without requiring high precision in the arrangement of conductive regions.
