Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Type-C connectors have poor waterproof performance due to assembly gaps between insulating bodies, allowing water and dust to enter.
Innovation Solution
A waterproof connector design featuring an integral insulating body with terminal grooves and a receiving channel, where conductive terminals are inserted and an insulating block is injection-molded to seal the gaps, eliminating the need for additional assembly steps and enhancing sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a segmented waterproof structure with multiple insulating bodies is used, then the connector can be assembled with separate components, but assembly gaps are created that reduce waterproof performance
Solution Approach 1:
The patent combines multiple separate insulating bodies into a single integral insulating body formed by injection molding. This merging eliminates the assembly gaps between separate components while maintaining manufacturing feasibility through the injection molding process, thereby resolving the contradiction between ease of manufacture and waterproof performance.
Solution Approach 2:
The integral insulating body incorporates multiple functional elements (terminal grooves, receiving channels, sealing structures) as integrated segments within a single molded piece. This segmentation of functions within a unified structure allows complex waterproof features to be achieved without creating assembly gaps between separate components.
2Reliability
If terminal grooves and receiving channels are integrated into the insulating body, then waterproof sealing is improved, but the injection molding process becomes more complex
Solution Approach 1:
The patent implements terminal grooves and receiving channels as nested cavities and channels within the integral insulating body structure. These internal features are molded as hollow spaces and recesses within the single insulating body, allowing complex waterproof geometries to be achieved through the injection molding process without requiring additional assembly steps or separate components.
3Reliability
If an insulating block is injection-molded to seal gaps, then waterproof performance is enhanced, but the manufacturing process requires additional injection molding steps
Solution Approach 1:
The patent incorporates the sealing function directly into the insulating body during its initial injection molding process. The terminal grooves, receiving channels, and sealing features are all formed in a single preliminary molding action, eliminating the need for subsequent injection molding steps to add sealing blocks. This preliminary action approach maintains productivity while achieving enhanced waterproof performance.
