Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulating blocks with through holes are used to electrically insulate conductive terminals from shielding bodies, then electrical insulation is achieved, but the assembling efficiency decreases due to the need for precise alignment and one-by-one assembly
Solution Approach 1:
The patent merges the insulating block and the insulating paint layer into a unified insulating structure. The insulating paint layer is applied directly to the inner surface of the receiving slot, eliminating the need for separate insulating blocks and their associated assembly processes, thus improving assembling efficiency while maintaining electrical insulation.
Solution Approach 2:
The patent replaces the mechanical assembly of insulating blocks with a coating process. Instead of physically assembling insulating blocks with through holes, the insulating paint layer is applied through spraying or dipping, substituting a mechanical assembly operation with a more efficient coating process that improves productivity.
2Reliability
If insulating blocks with small through holes are used, then electrical insulation is achieved, but the alignment difficulty increases affecting assembling efficiency
Solution Approach 1:
The patent combines the insulating function with the slot structure itself by applying the insulating paint layer directly to the inner surface of the receiving slot. This eliminates the need for separate insulating blocks with small through holes, thereby removing the alignment difficulty while maintaining electrical insulation between conductive terminals and shielding bodies.
3Productivity
If insulating paint layer is used instead of insulating blocks, then assembling efficiency is improved, but the shielding effect may be compromised
Solution Approach 1:
The patent changes the physical state and application method of the insulating material from solid blocks to a liquid paint layer that can be sprayed or dipped onto the slot surface. This parameter change allows the insulating material to conform perfectly to the slot geometry, ensuring comprehensive coverage and maintaining the shielding effect while dramatically improving assembling efficiency.
Solution Approach 2:
The patent replaces the mechanical insulating block structure with a coating-based insulating paint layer. This substitution allows the insulating material to be applied as a continuous layer that conforms to the slot surface, ensuring effective electromagnetic shielding while eliminating the assembly complexity associated with mechanical insulating blocks.
