Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical contacts for CPU-PCB connectors face a challenge in achieving both superior mechanical resiliency and electrical conduction characteristics using a single material, as materials tend to prioritize one property over the other.
Innovation Solution
The design incorporates a conducting part with enhanced conductivity and a supporting part with improved strength/resiliency, featuring a main body with obliquely extending contacting arms and a secondary body with curved supporting arms that securely engage, allowing minor relative movement to provide both electrical and mechanical functions with optimized transmission paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single material is used for the electrical contact, then the manufacturing process is simple, but the contact cannot achieve both superior mechanical resiliency and electrical conduction characteristics
Solution Approach 1:
The electrical contact is divided into two distinct parts: a conducting part (with better conduction characteristic) and a supporting part (with better resiliency/strength characteristic). Each part is made from materials optimized for its specific function, allowing both electrical and mechanical requirements to be met simultaneously without compromising manufacturing feasibility.
Solution Approach 2:
The patent employs composite construction by combining two different materials with complementary properties. The conducting part uses material with superior electrical conduction, while the supporting part uses material with superior mechanical resiliency and strength. This composite approach resolves the contradiction by achieving dual characteristic performance that cannot be obtained with a single material.
2Reliability
If the conducting part uses a material with superior conduction characteristic, then electrical performance is improved, but mechanical resiliency and strength are reduced
Solution Approach 1:
The electrical contact is segmented into a conducting part and a supporting part, each optimized for its specific function. The conducting part uses material with superior electrical conduction properties, while the supporting part uses material with superior mechanical strength and resiliency. This functional segmentation allows each part to excel at its primary role without compromise.
Solution Approach 2:
Different parts of the electrical contact are made with different material qualities suited to their specific functions. The conducting part has local quality optimized for electrical conduction, while the supporting part has local quality optimized for mechanical strength and resiliency. This local differentiation resolves the contradiction between electrical and mechanical performance requirements.
3Strength
If the supporting part uses a material with superior resiliency/strength characteristic, then mechanical performance is improved, but electrical conduction characteristic is reduced
Solution Approach 1:
The electrical contact is divided into a conducting part and a supporting part with distinct material properties. The supporting part uses material optimized for mechanical resiliency and strength, while the conducting part uses material optimized for electrical conduction. This segmentation allows the supporting part to provide mechanical support without being constrained by electrical conduction requirements.
Solution Approach 2:
The supporting part has local quality specifically optimized for mechanical strength and resiliency, while the conducting part has local quality optimized for electrical conduction. This functional differentiation through local quality optimization resolves the contradiction by allowing each part to perform its primary function with superior characteristics.
4Strength
If the contact structure uses a longer transmission path for mechanical support, then mechanical resiliency is improved, but electrical transmission efficiency is reduced
Solution Approach 1:
The patent segments the contact structure into a conducting part with a shorter transmission path optimized for electrical conduction, and a supporting part with a longer curved path optimized for mechanical resiliency. This segmentation allows the electrical and mechanical functions to have independently optimized path lengths without compromising either function.
Solution Approach 2:
The conducting part acts as an intermediary that provides a direct, short transmission path for electrical conduction, while the supporting part provides a longer curved path for mechanical support. The conducting part mediates the electrical function independently from the mechanical support function, allowing optimal path lengths for each function.

AI summary
An electrical contact for use with an electrical connector includes a conducting part and a supporting part wherein the conducting part has a better conduction characteristic than the supporting part while the supporting part has a better resiliency/strength characteristic than the conducting part. The conducting part includes a main body, an upper contacting arm extending upwardly from the main body and a lower contacting arm extending downwardly from the main body. The supporting part includes a secondary body, an upper supporting arm upwardly extending from the secondary body and a lower supporting arm downwardly extend from the secondary body. The main body and the secondary body are engaged together securely. The end of the upper contacting arm and that of the upper supporting arm are coupled together and the end of the lower contacting arm and that of the lower supporting arm are coupled together.
