Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic component is tightly mounted inside the elastically deformable wall to ensure secure retention, then the reliability of the electronic component is improved, but the difficulty of insertion and extraction increases significantly
Solution Approach 1:
The retaining wall is segmented with N grooves that divide the wall structure into multiple sections. These grooves allow the wall to deform locally during insertion and extraction while maintaining overall structural integrity, enabling automated tools to insert and extract components without excessive force
Solution Approach 2:
The grooves change the mechanical parameters of the retaining wall by creating controlled deformation zones. During insertion, the grooves allow the wall to expand and accommodate the component; during extraction, they allow the wall to deform to release the component, thus facilitating automated operations
2Duration of action of stationary object
If the patch material is made highly elastic to accommodate tire deformations and dampen stresses, then the mechanical endurance of the patch is improved, but the heating of the patch increases under high stress conditions
Solution Approach 1:
The grooves segment the retaining wall structure, creating multiple independent deformation zones. This segmentation allows stress to be distributed across multiple regions rather than concentrated in one area, reducing overall heat generation while maintaining the elastic properties needed for tire deformation accommodation
Solution Approach 2:
The grooves create local regions with different mechanical properties. The grooved areas have enhanced flexibility and stress distribution characteristics, while other areas maintain structural rigidity. This local differentiation allows the patch to accommodate deformations with reduced overall heating
3Ease of operation
If the opening material is made highly elastic to allow easy insertion and extraction, then the ease of operation is improved, but the tight fit required for secure mounting is compromised
Solution Approach 1:
The grooves enable the retaining wall to dynamically change its deformation characteristics. During insertion, the grooves allow maximum elasticity for easy component entry. Once the component is in place, the wall's elastic properties provide secure retention. The dynamic response to different operational phases resolves the contradiction between ease of operation and secure mounting
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution facilitates easy and reliable insertion and extraction of electronic components, maintains accurate physical parameter measurements, and enhances the mechanical endurance of the fastening device by preventing overpressure and overheating.
Implementation Method 1
the reduction of the air cavity within the open volume does not create overpressure in this cavity due to pressure equilibrium with the outside
Implementation Method 2
The wall serves to grip or hold the electronic component in position within the device, the electronic component being tightly mounted inside the elastically deformable wall
Implementation Method 3
The opening allows the electronic component to be inserted into and removed from the patch thanks to the elasticity of the opening material
