Solution Overview
Problem
Existing cable bushing devices are complex, costly, and inefficient in terms of space usage and assembly effort, particularly when routing multiple cables through partition walls, with suboptimal sealing and strain relief for cables of different diameters.
Innovation Solution
A simple, cost-effective cable bushing device comprising a soft body with multiple bores and membranes, manufactured as a single unit using polyurethane or silicone gel, which can be easily adapted to various cable diameters, providing reliable sealing and strain relief through a deformable membrane that forms a funnel shape around the cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual cable bushing modules are used to route several cables through a partition wall, then each cable achieves optimal sealing and strain relief, but the device complexity increases and assembly becomes time-consuming
Solution Approach 1:
The patent combines multiple cable bushing functions into a single integrated soft body with multiple body bores and body membranes. This unified structure eliminates the need for multiple separate cable bushing modules, reducing device complexity while maintaining sealing quality for each cable passage. The soft body integrates multiple sealing and strain relief functions into one component that can accommodate several cables simultaneously.
Solution Approach 2:
The soft body is designed as a universal component that can handle multiple cables of different diameters through its multiple body bores. Each bore with its corresponding body membrane provides individualized sealing and strain relief, while the overall structure serves as a single multi-functional element that replaces numerous individual cable bushings.
2Reliability
If multiple individual cable bushing modules are used to ensure consistent sealing quality for each cable, then sealing reliability is maintained, but the assembly effort and installation time increase significantly
Solution Approach 1:
By merging multiple cable bushing functions into a single soft body component, the patent enables all cable passages to be installed simultaneously as one unit. This eliminates the sequential assembly process required for multiple individual modules, dramatically reducing assembly time while maintaining consistent sealing quality across all cable bores through the standardized body membrane design.
3Quantity of substance
If traditional cable bushing devices are used to route multiple cables through a partition wall, then cable passage is achieved, but the space required increases and packing density decreases
Solution Approach 1:
The soft body is designed with multiple body bores arranged in a compact, space-efficient configuration that allows cables of different diameters to pass through in close proximity. The nested arrangement of multiple functional bores within a single soft body structure maximizes cable routing capacity while minimizing the overall space occupied by the cable bushing device.
4Strength
If precise matching of cutouts to cable diameter is required in multi-layer compressible material bushings, then cable fixation is achieved, but manufacturing precision requirements increase and quality varies across different cable positions
Solution Approach 1:
The body membranes are designed with varying thicknesses at different locations to accommodate cables of different diameters. This parameter variation in membrane thickness allows each body bore to provide optimal sealing and strain relief for its specific cable size without requiring precise pre-matched cutouts, thereby reducing manufacturing precision requirements while maintaining cable clamping strength.
