Layered Seal Structure to Prevent Projecting Portion Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional seal structures for electrical connectors experience reduced sealability and increased size due to abnormal deformation of projecting portions, leading to decreased pressure on the sealed structure and required spacing between projecting portions.
Innovation Solution
A seal structure comprising a first layer with a harder composition material and a second layer with a softer composition material, where at least part of the first layer's projecting portion is covered by the second layer's projecting portion, inhibiting abnormal deformation and enhancing sealability while allowing for reduced size dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single layer with projecting portions is used, then the structure is simple, but abnormal deformation occurs leading to reduced sealability
Solution Approach 1:
The seal structure is divided into a first layer and a second layer, each with distinct functions. The first layer provides structural support while the second layer ensures sealing, preventing abnormal deformation that occurs in single-layer designs.
Solution Approach 2:
The invention uses composite material construction with a harder first layer and a softer second layer. This combination of materials with different properties prevents abnormal deformation while maintaining sealability, resolving the contradiction between reliability and structural simplicity.
2Ease of operation
If the projecting portion deforms abnormally, then insertion is easier, but the pressure on the sealed structure decreases reducing sealability
Solution Approach 1:
By separating the sealing function (second layer) from the structural support function (first layer), the design allows controlled deformation for easy insertion while the first layer prevents excessive deformation that would compromise sealing pressure.
Solution Approach 2:
The invention changes the hardness parameter of different layers - the first layer is harder to maintain structural integrity and pressure, while the second layer is softer to allow controlled deformation for insertion. This parameter differentiation resolves the contradiction between ease of operation and reliability.
3Reliability
If spacing is provided between projecting portions to prevent abnormal deformation, then sealability is maintained, but the overall width of the seal structure increases
Solution Approach 1:
The composite structure with a harder first layer provides structural support that prevents abnormal deformation of the projecting portions, allowing them to be placed closer together without compromising sealability. This reduces the overall width while maintaining reliability.
Solution Approach 2:
By changing the hardness parameter of the first layer material, the invention enables the projecting portions to resist abnormal deformation forces, allowing reduced spacing between them and thus reducing the overall width of the seal structure while maintaining sealability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The configuration provides improved sealability and increased pressure on the sealed structure, while reducing the overall size of the seal structure, specifically in electrical connectors, by limiting the deformation of the projecting portions and allowing for more efficient sealing without increasing the size of the connector housing.
Implementation Method 1
a composition material of the first layer is harder than a composition material of the second layer

AI summary
A seal structure includes a first layer having at least one first upward projecting portion, and a second layer having at least one first upward projecting portion. At least part of the first upward projecting portion of the first layer is covered with the first upward projecting portion of the second layer, and a composition material of the first layer is harder than a composition material of the second layer.
