Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If discharge electrodes are connected using a plate-shaped electrode connection part with hooks, then the discharge electrodes can be fixed, but electric discharge occurs on the hooks causing EMC problems and functional issues
Solution Approach 1:
The harmful hook structure is completely removed from the design. Instead of using hooks to catch and fix the discharge electrode wire, the patent uses a plate-shaped electrode connection part with through-holes that allow the wire to pass through and be secured by insulating materials, eliminating the source of abnormal electric discharge
Solution Approach 2:
An insulating material is introduced as an intermediary between the conductive wire and the electrode connection part. This insulating material prevents direct contact that would cause electric discharge, while still allowing mechanical fixation of the wire in place
2Strength
If discharge electrodes are fixed using hooks on a plate-shaped connection part, then the structure can hold the wire, but the assembly process becomes complex and assemblability deteriorates
Solution Approach 1:
The fixation function is segmented into multiple independent elements: the plate-shaped connection part provides structural support, the through-holes provide positioning, and the insulating materials provide both electrical isolation and mechanical anchoring. This segmentation allows each element to perform its specific function simply, improving overall assemblability
Solution Approach 2:
Instead of using protruding hooks to catch the wire from the outside, the design inverts the approach by using through-holes that the wire passes through, with fixation occurring from the opposite side or within the structure, simplifying the assembly process
