Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable glands are used, then sealing protection is provided, but application is laborious and time-consuming
Solution Approach 1:
The gasket is divided into multiple longitudinal portions (first portion with greater deformability, second portion with lower deformability) that can be independently deformed during application. This segmentation allows the gasket to adapt to different cable sizes and shapes more easily, reducing installation time while maintaining sealing reliability.
Solution Approach 2:
The gasket incorporates portions with different deformability characteristics that allow dynamic adaptation during installation. The first portion with greater deformability can be compressed more easily to accommodate the cable, while the second portion maintains structural integrity, enabling quick application without compromising the sealing function.
2Reliability
If conventional cable glands are used, then sealing protection is provided, but versatility for various cable cross-sections is limited
Solution Approach 1:
Different portions of the gasket have different local properties: the first longitudinal portion has greater deformability to accommodate various cable cross-sections, while the second longitudinal portion has lower deformability to maintain sealing integrity. This local differentiation enables the single gasket design to work with diverse cable types and sizes while ensuring reliable sealing.
Solution Approach 2:
The gasket utilizes portions with different deformability parameters to adapt to varying cable cross-sections. The first portion's higher deformability allows it to conform to different cable geometries, while the second portion's lower deformability ensures consistent sealing pressure, providing versatility across cable types without sacrificing sealing reliability.
3Ease of operation
If the gasket body is made uniformly deformable, then easy application is achieved, but adhesion and sealing reliability are compromised
Solution Approach 1:
The gasket employs different deformability levels in different longitudinal portions: the first portion has greater deformability to facilitate easy application and cable insertion, while the second portion has lower deformability to ensure strong adhesion to the cable and reliable sealing. This local quality differentiation resolves the contradiction between ease of operation and sealing reliability.

AI summary
A gasket for electric cables includes a main portion made of elastic material; a through hole that passes longitudinally through the main body and constitutes the seat of a cable to be insulated; a longitudinal slit passes through the body of the gasket and connects the through seat to the outside, allowing, by virtue of the elastic deformability of the material of the gasket, the insertion of the cable in the through seat.
