Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face issues with wear and tear due to frequent plugging and docking, leading to decreased fitting force and unstable signal transmission, especially in thin and miniaturized electronic products.
Innovation Solution
A locking and stabilizing structure for electrical connectors, featuring a socket and plug connector design with a metal shell, limit frames, and a handle mechanism that includes shaft grooves and supporting portions to securely lock the connectors, preventing shaking and enhancing operational simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the main body and base are fitted together using convex buckle and buckle groove, then the connector can be assembled by fitting, but the fitting force decreases due to mutual wear and tear from multiple plugging and docking
Solution Approach 1:
The connector is divided into separate components: the main body with convex buckles and the base with buckle grooves. This segmentation allows for easy assembly through fitting while the patent addresses the wear issue by designing the buckles to engage with the grooves in a way that distributes stress and reduces mutual wear and tear during repeated plugging and docking operations.
Solution Approach 2:
The patent introduces a dynamic locking mechanism where the handle can rotate between locked and unlocked positions. The shaft portions of the handle extend into the button holes of the limit frames, creating a dynamic structure that maintains stable positioning during operation while allowing easy assembly and disassembly, thereby preserving fitting force stability over multiple operations.
2Volume of moving object
If the connectors are miniaturized for thin electronic products, then the product thickness is reduced, but the positioning effect between conductive terminals and contact terminals becomes insufficient
Solution Approach 1:
The patent adds a rotational dimension to the locking mechanism through the handle structure. The shaft portions extend into the button holes and the handle can rotate to lock the connectors together. This dimensional addition provides enhanced positioning stability for the miniaturized connectors, ensuring precise alignment of conductive terminals with contact terminals even in thin electronic products.
3Ease of operation
If the handle is designed to rotate for locking and unlocking, then the operational simplicity is improved, but the structure complexity increases
Solution Approach 1:
The handle serves multiple functions: it acts as a locking mechanism when rotated to the locked position, provides structural support through its shaft portions extending into the button holes, and enables easy unlocking by rotating to the unlocked position. This multi-functionality justifies the increased structural complexity by consolidating several functions into a single component, improving ease of operation without requiring multiple separate mechanisms.
