Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an adhesive member is used to attach the film to the supporting member, then the attachment strength is improved, but the device complexity increases due to the need for additional components and assembly steps
Solution Approach 1:
The adhesive member is divided into multiple segments separated by slits, allowing each segment to independently conform to the supporting member's surface features while maintaining overall attachment functionality. This segmentation reduces stress concentration and improves adaptability to curved or irregular surfaces without requiring a completely different attachment mechanism.
Solution Approach 2:
The adhesive member's physical parameters are modified by introducing slits that change its mechanical properties, allowing it to stretch and conform to curved surfaces. The slits enable the adhesive material to expand and contract dynamically, adapting to surface curvature changes while maintaining bond strength.
2Adaptability or versatility
If the adhesive member is made flexible to conform to curved surfaces, then the adaptability is improved, but the attachment strength may deteriorate due to reduced structural rigidity
Solution Approach 1:
By segmenting the adhesive member into multiple sections separated by slits, each segment can independently flex and conform to curved surfaces while the collective segments maintain overall attachment strength. The segmentation allows local adaptation without compromising global structural integrity.
Solution Approach 2:
The adhesive member functions as a composite structure combining flexible adhesive material with structural support from the slit pattern. This composite design provides both the flexibility needed for curved surface adaptation and the structural integrity required for strong attachment.
3Adaptability or versatility
If the adhesive member includes slits to allow stretching, then the flexibility is improved, but the manufacturing precision becomes more difficult to control
Solution Approach 1:
The segmentation into slits creates a modular structure that is more tolerant of manufacturing variations. Each slit segment can be independently controlled, and minor dimensional variations in individual segments do not propagate through the entire adhesive member, improving overall manufacturing precision control.
