Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional rigid retaining elements are used to protect components, then structural strength is improved, but protection against impacts and leaks deteriorates due to lack of shock absorption
Solution Approach 1:
The retaining elements are made from elastomer material instead of traditional rigid materials, fundamentally changing the material parameter from rigid to elastic. This allows the retaining elements to absorb impact energy through deformation while maintaining structural integrity, thereby protecting components against impact damage while preserving necessary structural strength.
Solution Approach 2:
The retaining elements are produced as a composite structure combining elastomer material with integrated sealing components. This composite approach allows the retaining elements to simultaneously provide mechanical retention, shock absorption through elastomer deformation, and sealing functionality, protecting components from both impacts and leaks.
2Reliability
If complex sealing means are added to prevent leaks, then sealing performance is improved, but manufacturing costs and assembly effort increase
Solution Approach 1:
The sealing function is merged directly into the retaining elements by integrating sealing components into the elastomer structure. This eliminates the need for separate sealing means and simplifies assembly, as the retaining elements themselves provide both mechanical retention and sealing functionality in a single integrated component.
Solution Approach 2:
The elastomer material inherently provides sealing functionality through its elastic properties and ability to deform around mating surfaces. The retaining elements self-seal by creating friction-based connections and deformable seals without requiring additional sealing components, thereby simplifying the overall device structure and assembly process.
3Stability of the object's composition
If rigid housing structures are used to protect components, then structural stability is improved, but shock absorption and energy absorption deteriorate
Solution Approach 1:
The housing structure incorporates elastomer material with high elastic modulus, changing the structural parameter from rigid to elastically deformable. This allows the housing to absorb impact energy through elastic deformation while maintaining sufficient structural stability to protect internal components during normal operation.
Solution Approach 2:
The elastomer retaining elements and housing structure provide beforehand cushioning by being pre-configured to deform and absorb impact energy. The elastic material is positioned to directly contact and protect vulnerable components, creating a cushioning effect that activates automatically upon impact without requiring additional active protection mechanisms.
4Object-affected harmful factors
If elastomer material is used for retaining elements, then shock absorption and sealing are improved, but manufacturing precision may deteriorate due to material deformability
Solution Approach 1:
The elastomer material is selected and processed to achieve optimal cross-linking density and hardness, changing the material parameters to balance deformability for shock absorption with sufficient dimensional stability for precise manufacturing. This allows the retaining elements to be manufactured with adequate precision while maintaining the elastic properties needed for impact protection.
