Waterproof Adapter Assembly for Stable Center Pin Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof adapters suffer from instability in signal transmission due to skewing of insulative components and reduced electrical conductivity caused by resilient materials, allowing moisture ingress and affecting conductor connections.
Innovation Solution
A waterproof adapter assembly with a design that includes a main casing, outer casing, insulative component, and center pin set, where the insulative component is mounted with a ring groove to reduce deflection and a waterproof rubber ring that seals against annular surfaces, preventing skewing and enhancing the electrical connection between center pin sets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If resilient materials are used for insulative components and soft materials for waterproof rubber ring, then ease of assembly is improved, but manufacturing precision deteriorates due to compression-induced skewing
Solution Approach 1:
The patent changes the physical state of the insulative component from resilient to rigid, and the waterproof rubber ring from soft to semi-rigid. This parameter change eliminates compression-induced skewing while maintaining assembly feasibility through the elastic recovery mechanism of the semi-rigid rubber ring.
Solution Approach 2:
The patent introduces a cushioning structure through the elastic recovery mechanism of the semi-rigid waterproof rubber ring. This beforehand cushioning compensates for assembly variations and prevents excessive compression that would cause skewing, thereby maintaining positioning precision during assembly.
2Reliability
If waterproof rubber ring is used for sealing, then reliability is improved, but electrical conductivity deteriorates due to weak conductivity of rubber material
Solution Approach 1:
The patent introduces a conductive layer as an intermediary between the waterproof rubber ring and the center pin set. This conductive intermediary maintains the sealing function of the rubber ring while restoring electrical conductivity, as the conductive layer provides the necessary electrical path without compromising the sealing reliability of the rubber component.
Solution Approach 2:
The patent creates a composite structure by combining the waterproof rubber ring with a conductive layer. This composite material solution integrates the sealing properties of rubber with the electrical conductivity of the conductive layer, simultaneously achieving both sealing reliability and electrical conductivity efficiency.
3Reliability
If center pin set contacts waterproof rubber ring for sealing, then sealing is improved, but electrical conductivity efficiency deteriorates
Solution Approach 1:
The patent introduces a conductive layer as an intermediary between the waterproof rubber ring and the center pin set. This conductive intermediary maintains the sealing function of the rubber ring while restoring electrical conductivity, as the conductive layer provides the necessary electrical path without compromising the sealing reliability of the rubber component.
4Ease of operation
If insulative components are compressed by jacketing set, then ease of assembly is improved, but positioning precision deteriorates due to skewing
Solution Approach 1:
The patent changes the physical state of the insulative component from resilient to rigid, eliminating compression-induced skewing. The semi-rigid waterproof rubber ring maintains assembly feasibility through elastic recovery while preventing excessive compression that would compromise positioning precision.
Solution Approach 2:
The patent introduces a cushioning structure through the elastic recovery mechanism of the semi-rigid waterproof rubber ring. This beforehand cushioning compensates for assembly variations and prevents excessive compression that would cause skewing, thereby maintaining positioning precision during assembly.
