Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors are prone to short circuits when electric wires are stretched or subjected to external forces, and the use of separate insulating covers increases costs and complexity.
Innovation Solution
A connector design featuring a sealing member made of resilient material with an integrated electric wire protecting part that extends along the wire to prevent contact between the wire and the shield member, reducing the number of components and manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate insulating electric wire cover is provided between the tubular connecting member and the electric wire, then short circuit prevention is improved, but the number of components increases and cost increases
Solution Approach 1:
The patent combines the insulating electric wire cover and the sealing member into a single integrated component. The sealing member is formed with an integrated wire cover portion that directly covers the electric wire, eliminating the need for a separate insulating cover while maintaining both sealing and insulation functions. This merging reduces the number of components and assembly steps while ensuring reliable short circuit prevention.
2Reliability
If a separate insulating electric wire cover is provided, then short circuit prevention is improved, but manufacturing cost increases
Solution Approach 1:
The sealing member and wire cover are molded as a single integrated component in one manufacturing process. The wire cover portion is formed integrally with the sealing member body, eliminating the need for separate manufacturing and assembly operations. This integration reduces manufacturing complexity and cost while ensuring reliable insulation and sealing performance.
3Reliability
If an electric wire cover made of resin is used, then insulation is provided, but the cover is ruptured by external force such as shock
Solution Approach 1:
The patent employs a sealing member made of elastomeric material that integrates both the sealing function and the wire cover function. The elastomeric material provides both electrical insulation properties and high resistance to external forces such as shock and vibration. This composite approach eliminates the weakness of pure resin covers while maintaining insulation performance through the inherent insulating properties of the elastomeric material.
4Object-affected harmful factors
If the electric wire is stretched by external force, then the wire can be ruptured at the joint portion, but no protection is provided
Solution Approach 1:
The sealing member integrates multiple protective functions: it seals between the housing and terminal joint part, provides insulation, and protects the electric wire from external forces. The wire cover portion of the sealing member extends to cover the wire near the joint portion, providing mechanical protection against stretching and shock without requiring additional protective structures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents short circuits without increasing costs by using a resilient material for the electric wire protecting part, which is molded integrally with the sealing member, ensuring reliable protection against external forces.
Implementation Method 1
a sealing member which is made of a resilient material having waterproof and insulation properties to seal between the housing and the terminal joint part
Implementation Method 2
a sealing member which is made of a resilient material having waterproof and insulation properties
Implementation Method 3
since the electric wire protecting part is made of a resilient material, as compared to the case in which an electric wire protecting part is made of hard resin, it is possible to prevent the electric wire without being damaged by an external force, such as shock, from an exterior
