Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the insulating portion is formed only of an insulating material, then the manufacturing cost is reduced and the structure is simplified, but signal interference occurs between contact portions when transmitting high-frequency signals
Solution Approach 1:
The insulating portion is formed using a composite material comprising an insulating base material and a conductive pattern layer. The conductive pattern layer is formed on the insulating base material in a pattern that corresponds to the contact portions, creating a shield that blocks signal interference while maintaining electrical insulation. This composite structure resolves the contradiction by adding signal protection capability without completely sacrificing manufacturing simplicity.
Solution Approach 2:
The conductive pattern layer acts as an intermediary element between the insulating base material and the contact portions. It serves as a shield that intercepts and redirects electromagnetic signals, preventing direct interference between adjacent contact portions while allowing the insulating portion to maintain its structural and insulating functions.
2Productivity
If the contact portions are closely arranged to increase testing capacity, then the productivity is improved, but signal interference between adjacent contact portions increases
Solution Approach 1:
The insulating portion with conductive pattern serves as a dual-function element that provides both electrical insulation and electromagnetic shielding. This allows contact portions to be closely arranged for increased testing capacity while the conductive pattern in the insulating portion prevents signal interference between adjacent contacts.
Solution Approach 2:
The insulating portion is designed to perform multiple functions simultaneously: electrical insulation between contact portions and electromagnetic shielding against signal interference. This multi-functionality enables closer arrangement of contact portions without compromising signal integrity, thereby increasing testing capacity.
