Optical Controller Socket with Bent Contact and Segmented Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical controller sockets have a large gold-plated contact surface area, leading to high production costs and inefficient waterproof sealing due to a large waterproof spacer design, which results in potential water leakage and material wastage.
Innovation Solution
The optical controller socket features a reduced gold-plated area through a bent contact piece design with a 90-degree bend and an arc-shaped contact surface, and a segmented waterproof sealing ring with a central positioning flange and side positioning flange to ensure proper compression and alignment, reducing material usage and production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large gold-plated contact surface area is used to ensure contact performance, then the contact reliability is improved, but the production cost increases significantly
Solution Approach 1:
The patent applies local quality by concentrating the gold-plating only on the contact surface area rather than the entire contact piece. The contact surface is specifically gold-plated to ensure good electrical contact and corrosion resistance, while other non-critical areas use base metal without expensive gold plating. This selective application of expensive material only where functionally necessary resolves the contradiction between contact reliability and production cost.
2Reliability
If a large area waterproof spacer is used to ensure waterproof sealing, then the sealing reliability is improved, but the raw material waste increases
Solution Approach 1:
The waterproof spacer is segmented into a precise ring shape with specific width (2-3mm) rather than using a large solid area. The spacer forms a circular ring around the central hole, concentrating the waterproofing function only where needed at the interface between base and mounting surface. This segmentation eliminates unnecessary material in the center and outer areas, reducing raw material waste while maintaining sealing reliability.
Solution Approach 2:
The patent uses partial action by applying the waterproof spacer only to the essential circular edge areas (2-3mm wide) required for sealing, rather than covering the entire surface area. This partial application provides sufficient waterproof protection at the critical interface while avoiding excessive material usage in non-critical areas, thus resolving the contradiction between sealing reliability and material waste.
3Reliability
If a large area waterproof spacer is used to achieve waterproof property, then the sealing effect is improved, but the device complexity and material cost increase
Solution Approach 1:
The waterproof spacer is designed as a simple circular ring segment with uniform width (2-3mm) rather than a complex large-area structure. This segmented ring design concentrates the waterproofing function at the critical interface while simplifying the overall structure, reducing both material usage and design complexity while maintaining effective waterproof sealing.
