Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conductive particles are contained in elastic insulation material to form conductive portions, then conductivity is achieved, but conductive particles easily escape to the outside due to frequent contacts
Solution Approach 1:
The conductive particle is divided into two parts: a solid core and a through-hole. The through-hole allows elastic insulation material to penetrate into the particle, creating an anchor effect that prevents escape while maintaining conductivity.
Solution Approach 2:
The elastic insulation material is nested into the through-hole of the conductive particle, creating a nested structure where the material penetrates and anchors the particle within the conductive portion.
2Reliability
If ball-shaped conductive particles are used, then conductivity is achieved, but they easily escape from insulation material due to their shape
Solution Approach 1:
The ball-shaped particle is segmented by creating a through-hole, transforming it from a solid sphere to a hollow structure with anchoring capability. This segmentation allows the particle to maintain its conductive function while gaining retention stability.
Solution Approach 2:
The conductive particle is combined with elastic insulation material in a composite structure, where the material fills the through-hole to create a hybrid particle that exhibits both conductivity and enhanced retention properties.

AI summary
The present invention relates to a test socket that is disposed between a blood test device and a test apparatus to electrically connect a terminal of the blood test device and a pad of the test apparatus with each other. Conduction units that are arranged at positions corresponding to the terminal of the blood test device and show conductivity in a thickness direction have: conduction units that are arranged in such a manner that multiple conductive particles are arranged in the thickness direction in an elastic insulating material; and an insulating support unit that supports and insulates each of the conduction units. The conductive particles are provided with through-holes bored through one surface and another surface other than the one surface, and the through-holes are filled with the elastic insulating material.
