Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable glands are limited in their ability to accommodate a range of cable diameters and numbers, leading to suboptimal waterproof performance and complex installation processes, particularly in humid environments where multiple cables must be intertwined to fit through a single gland.
Innovation Solution
A cable threading component comprising a substrate with through holes, a sealing sheet with sealing holes, and a mounting plate with guide holes, forming independent threading holes that allow cables to pass through while maintaining sealing, with a tubular portion and sealing core for enhanced sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cable gland is used to accommodate multiple cables, then the device complexity is reduced and cost is lowered, but the waterproof performance deteriorates when the number of cables is not within the limited range
Solution Approach 1:
The single cable gland is segmented into multiple independent cable glands arranged in an array. Each cable gland can independently accommodate one or more cables, allowing the system to handle varying numbers and sizes of cables while maintaining IP68 waterproof performance for each individual cable path.
Solution Approach 2:
The array of cable glands is designed to be universally applicable to different cable configurations. By providing multiple cable glands in an array, the system can accommodate various numbers of cables (from 1 to many) and different cable diameters, replacing the need for a single cable gland that is limited to specific cable ranges.
2Adaptability or versatility
If cables are intertwined to fit through a single cable gland, then the cable diameter range is extended, but the installation difficulty increases and waterproof performance deteriorates
Solution Approach 1:
Instead of forcing multiple cables through a single cable gland by intertwining them, the invention segments the cable entry point into multiple independent cable glands. Each cable can pass through its own dedicated cable gland without needing to be intertwined with other cables, significantly simplifying installation while maintaining adaptability to various cable diameters.
Solution Approach 2:
Each cable gland in the array is designed with specific dimensions suitable for particular cable diameter ranges. This local optimization allows each cable to be accommodated in the most appropriate cable gland for its size, ensuring proper sealing and ease of installation without requiring cables to be bundled or intertwined.
3Ease of manufacture
If a single cable gland is used for cost considerations, then the device cost is reduced, but the applicability to different cable configurations is limited
Solution Approach 1:
The array of cable glands provides universal applicability to different cable configurations. By arranging multiple cable glands in an array format, the system can accommodate various numbers of cables and different cable diameters, making it suitable for diverse applications while maintaining cost-effectiveness through standardized manufacturing.
Solution Approach 2:
The cable glands are pre-arranged in an array configuration during manufacturing, with each position ready to accommodate specific cable types. This preliminary arrangement eliminates the need for complex field modifications or customizations when installing different cable configurations, reducing both cost and installation complexity.
4Device complexity
If multiple cables are intertwined through a single cable gland, then the number of cable glands is reduced, but the installation steps increase and time is consumed
Solution Approach 1:
The invention segments the cable entry system into multiple independent cable glands arranged in an array. This segmentation allows each cable to be installed independently through its own cable gland, eliminating the time-consuming process of intertwining multiple cables through a single gland while keeping the overall device complexity manageable through standardized modular construction.
