Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single cable gland is used to thread multiple cables, then cost is reduced and structure is simplified, but applicability is limited to a specific cable diameter range and installation becomes difficult when cable numbers vary
Solution Approach 1:
The cable gland is divided into multiple independent threading holes, each capable of accommodating cables of different diameters. This segmentation allows the device to handle varying numbers and sizes of cables simultaneously, resolving the limitation of single-diameter applicability while maintaining structural simplicity.
Solution Approach 2:
Each threading hole is designed with universal adaptability to accommodate cables of different diameters within a broad range. The standardized hole design with adjustable sealing mechanisms enables the cable gland to serve multiple cable configurations, enhancing versatility without increasing overall device complexity.
2Reliability
If a single cable gland is used with few cables (2-5 cables), then installation is simplified, but waterproof performance deteriorates when cable numbers deviate from the optimal range
Solution Approach 1:
Each threading hole is equipped with localized sealing components that can independently adapt to the number and diameter of cables inserted. This local quality adjustment ensures that waterproof performance is maintained for each cable configuration, whether 2 cables or 5 cables, without requiring complex overall structural changes or difficult installation procedures.
3Reliability
If traditional cable gland structure is used, then IP68 waterproof rating is achieved, but installation steps become cumbersome requiring rotation of cover twice
Solution Approach 1:
The sealing components are pre-configured within each threading hole in an optimized position, eliminating the need for multiple rotation steps during installation. The preliminary arrangement of sealing elements ensures that waterproof performance (IP68 rating) is achieved automatically upon cable insertion, simplifying the installation process while maintaining high reliability.

Implementation Method 1
a tubular portion extending into the through hole, and a sealing core provided on an inner side of the tubular portion, so that the sealing hole is closed before threading, and the sealing core peels off and the position of the sealing core is occupied by the cables when the cables pass through
