Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the filter is rigidly connected to the bearing block during assembly, then the alignment precision is improved, but the filter is subjected to stress deformation affecting filtering performance
Solution Approach 1:
The patent introduces an adhesive layer as an intermediary substance between the filter and the bearing block. This adhesive layer serves as a mediator that connects the two components while preventing direct rigid contact, thereby eliminating stress deformation on the filter while maintaining alignment precision.
Solution Approach 2:
The patent changes the mechanical connection parameter from rigid direct contact to flexible adhesive bonding. By altering the connection method, the system maintains positional stability while eliminating harmful stress transmission to the filter, resolving the contradiction between alignment precision and filtering performance.
2Productivity
If the filter is clamped by a clamping jig during manufacturing, then the assembly efficiency is improved, but the filter is subjected to external stress affecting its performance
Solution Approach 1:
The adhesive layer acts as a protective intermediary during the assembly process. Instead of the clamping jig directly contacting and stressing the filter, the adhesive absorbs and distributes the clamping forces, protecting the filter from harmful external stress while enabling efficient assembly.
Solution Approach 2:
The patent applies the cushioning principle by using the adhesive layer to preemptively absorb and distribute mechanical stresses before they can reach the filter. This prior cushioning protection prevents stress concentration on the filter during the clamping process, maintaining filter performance while enabling efficient assembly.
3Device complexity
If the bearing block directly contacts the filter, then the structural simplicity is improved, but the filter deformation under external shocks increases
Solution Approach 1:
The adhesive layer serves as a simple yet effective intermediary that cushions external shocks before they reach the filter. This minimal addition protects the filter from deformation while maintaining overall structural simplicity, as the adhesive integrates seamlessly into the existing bearing block-filter interface.
