Electrical Connection Member With Boss-Guided PCB Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection members for electronic devices face inefficiencies in assembly and are prone to damage due to misalignment during the coupling process, leading to improper insertion and potential damage to the heads and receptacles.
Innovation Solution
The introduction of a printed circuit board with a boss structure that protrudes from the electrical connection member, allowing for precise alignment and secure coupling of the head to the receptacle, utilizing a mechanism with openings that accommodate the boss structure to stabilize the assembly and prevent misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable length is made larger than the receptacle length to allow manual coupling, then the operator can couple heads to receptacles using tweezers or hands, but misalignment during coupling causes damage to heads and receptacles
Solution Approach 1:
The boss structure protruding from the cable assembly performs preliminary alignment action before the head couples with the receptacle. The boss inserts into the receptacle first, establishing correct positioning, which prevents misalignment damage during subsequent coupling operations
Solution Approach 2:
The boss structure acts as an intermediary element between the cable assembly and the receptacle. It mediates the coupling process by providing a guided insertion path and alignment reference, eliminating direct manual manipulation risks
2Productivity
If the head is arranged at wrong locations of the receptacle, then coupling can proceed, but defects such as damage to heads, damage and/or improper insertion of receptacles may be caused
Solution Approach 1:
The patent replaces manual mechanical positioning with a mechanical guide system consisting of the boss structure and receptacle opening. This substitution eliminates reliance on operator skill while maintaining high assembly speed through automatic alignment
Solution Approach 2:
The boss structure performs preliminary positioning action by inserting into the receptacle opening before the head couples. This pre-alignment ensures correct location is established prior to final coupling, preventing misalignment defects
3Manufacturing precision
If a boss structure is provided in the opening and protrudes from the electrical connection member, then precise alignment and secure coupling are achieved, but the device complexity increases
Solution Approach 1:
The cable assembly is segmented into functional components: the cable, the head, and the boss structure. This segmentation allows each component to perform its specific function independently while simplifying the overall design and manufacturing process
Solution Approach 2:
The boss structure serves multiple functions simultaneously: it provides alignment guidance, acts as a positioning reference, and enables secure coupling. This multi-functionality reduces the need for additional separate components, thereby limiting complexity increase
