Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional rigid housing structures are used, then shape stability is maintained, but deformation capability and stretch rate are insufficient
Solution Approach 1:
The housing employs a deformable portion made of flexible polymeric material that can bend and deform elastically. This flexible shell structure allows the housing to adapt to bending deformations while maintaining overall structural integrity and shape stability when not deformed, directly resolving the contradiction between rigidity and flexibility.
Solution Approach 2:
The housing combines rigid polymeric support parts embedded within the flexible deformable portion, creating a composite structure. The rigid support parts provide structural stability and prevent excessive deformation, while the flexible matrix material enables controlled bending and high stretch rates, thus resolving the contradiction between shape stability and deformation capability.
2Adaptability or versatility
If high elastic polymeric materials are used to increase stretch rate, then deformation capability improves, but creep resistance and shape stability deteriorate
Solution Approach 1:
The patent embeds rigid polymeric support parts within the high elastic polymeric material. The rigid support parts act as reinforcement that prevents creep and excessive deformation, while the elastic matrix material provides high stretch rate capability. This composite approach resolves the contradiction between achieving high deformation and maintaining dimensional stability.
Solution Approach 2:
The rigid support parts are strategically positioned at specific locations within the deformable portion where structural stability is most needed. This localized reinforcement allows the housing to achieve high overall stretch rates while maintaining shape stability and preventing creep at critical structural points.
3Adaptability or versatility
If the housing is made fully deformable to achieve high flexibility, then adaptability improves, but structural strength and stability deteriorate
Solution Approach 1:
The housing structure combines flexible polymeric material with embedded rigid polymeric support parts. The rigid support parts provide necessary structural strength and stability, while the flexible matrix material provides deformability. This composite construction resolves the contradiction between flexibility and structural strength.
Solution Approach 2:
The housing is divided into distinct functional regions: the deformable portion made of flexible material for adaptability, and embedded rigid support parts for structural strength. This segmentation allows each part to perform its specialized function, achieving both flexibility and structural integrity simultaneously.
