Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a functional assembly with multiple functions is added to enhance device functionality, then the scope of functions is enhanced, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single functional assembly: mechanical connection between flexible planar structure and guide tape, electrical connection for power supply to electrical consumers, and elastic compensation for transverse spacing variations. This merging approach enhances versatility while avoiding the complexity of separate components for each function.
Solution Approach 2:
The functional assembly is designed as a multi-functional component that simultaneously performs mechanical connection, electrical connection, and elastic compensation functions. This universal component approach allows a single element to serve multiple purposes, enhancing device adaptability without proportionally increasing complexity.
2Reliability
If a rigid electrical connection is used between guide tape and flexible planar structure, then electrical connection is established, but the connection fails when transverse spacing varies
Solution Approach 1:
The functional assembly incorporates elastic elements that allow dynamic adjustment to transverse spacing variations between guide rails. This dynamic capability enables the electrical connection to maintain reliability while adapting to changing geometric conditions during device operation.
Solution Approach 2:
The elastic functional assembly changes its physical parameters (length, shape) in response to transverse spacing variations, allowing it to maintain electrical connection under varying geometric conditions. The elastic deformation enables parameter adjustment without compromising connection integrity.
3Adaptability or versatility
If the transverse spacing between guide rails is made variable, then adaptability to different conditions is improved, but creasing of the flexible planar structure occurs
Solution Approach 1:
The functional assembly acts as an intermediary element between the flexible planar structure and the guide tape, absorbing the mechanical stresses caused by variable transverse spacing. This intermediary component prevents direct stress transmission to the flexible planar structure, thereby preventing creasing while allowing spacing variation.
