Connector Detection Member Prevents Short Circuits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing miniaturization and lightweight design of electronic device connectors make them prone to damage from external impacts and random metal material connections, leading to disconnection or short circuits due to exposed magnets in attach-type electrical connector devices.
Innovation Solution
A connector device with a coupling face featuring at least one magnetic member and a detection member that ensures electrical connection only when properly coupled to the electronic device's connector port, preventing external metal material attachment-induced disconnections by using a pogo pin structure with a detection pin that supplies power only upon correct alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnet is exposed to the outside of the connector for attachment, then the ease of operation is improved, but the reliability deteriorates due to random metal material attachment causing disconnection or short circuit
Solution Approach 1:
A detection member is introduced as an intermediary between the magnet and the external environment. This detection member selectively allows only authorized metal materials (with specific magnetic properties) to attach to the magnet, while blocking or detecting unauthorized metal materials. The detection member thus mediates the interaction between the exposed magnet and potential attachers, enabling easy attachment operation while ensuring connection reliability by preventing random metal material attachment.
2Weight of moving object
If the connector size is reduced for miniaturization, then the weight and volume are reduced, but the strength and durability worsen due to increased susceptibility to impact damage
Solution Approach 1:
The detection member acts as a protective buffer or cushioning element that is positioned before the critical connector components. When impact or unauthorized attachment occurs, the detection member absorbs or mitigates the harmful effects before they reach the main connector body or magnet, thereby protecting the miniaturized connector from impact damage while maintaining its small size and light weight.
