Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices in mobile electronic devices face challenges in preventing signal distortion and loss due to noise, while maintaining a compact size and ensuring stable coupling between plug and receptacle connectors, with a need for visual inspection of soldering states and minimized coupling force.
Innovation Solution
The connectors are designed with non-conductive bodies and shielders that surround the contacts, providing double shielding and simplified structure, allowing for easy coupling and visual inspection, while minimizing size and coupling force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If shielders are applied to block noise, then shielding performance is improved, but device size increases
Solution Approach 1:
The patent implements a nested shielder structure where an inner shielder is positioned inside an outer shielder, both surrounding the contact terminals. This multi-layer nested configuration enhances noise shielding performance by creating multiple barriers against electromagnetic interference, while the compact nested arrangement minimizes the overall volume increase compared to single-layer shielders of equivalent shielding effectiveness.
2Strength
If pressing force is applied to couple plug and receptacle connectors, then coupling strength is improved, but fastening deformation occurs
Solution Approach 1:
The patent incorporates cushioning elements or compliant structures within the connector assembly that are designed to absorb and distribute the pressing force applied during coupling. These pre-positioned cushioning features prevent excessive localized stress that would cause fastening deformation, while still maintaining sufficient coupling strength through distributed force transmission across multiple contact points.
Solution Approach 2:
The patent employs elastic or flexible materials with specific mechanical properties that allow the connector components to deform elastically under pressing force and then recover. By selecting materials and structures with appropriate elastic moduli and yield strengths, the design achieves sufficient coupling strength through controlled elastic deformation while preventing permanent fastening deformation.
3Reliability
If contact terminals are installed in a body for insulation, then electrical insulation is improved, but visual inspection of soldering becomes difficult
Solution Approach 1:
The patent utilizes a transparent or translucent plastic body material that provides complete electrical insulation while allowing optical transmission. This thin-film-like transparent enclosure maintains the insulating properties required for electrical safety while enabling visual inspection of the soldering connections through the body material, eliminating the need for disassembly or specialized inspection equipment.
