Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable wall bushing technologies lack flexibility in adapting to different installation situations, limiting their applicability and effectiveness in sealing cables through various types of walls.
Innovation Solution
A cable wall bushing system comprising a housing component with integrally formed webs and a closure component that can be adjusted by breaking points to accommodate different sealing elements, allowing for flexible configuration of openings to accommodate multiple cables and provide a sealing solution for various wall materials, including plastic and metal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cable wall bushing uses a fixed housing structure with predetermined openings, then the manufacturing and assembly process is simplified, but the adaptability to different installation situations and cable configurations is reduced
Solution Approach 1:
The housing is segmented into a main body and a separate closure component that can be selectively removed. The closure component divides the housing into multiple separable sections, allowing individual openings to be accessed or sealed as needed. This segmentation enables the bushing to adapt to different cable configurations while maintaining a simple integrated housing structure for ease of manufacture.
Solution Approach 2:
The closure component introduces dynamic functionality to an otherwise static housing structure. By allowing the closure component to be selectively removed or retained, the housing transitions between closed and open states, enabling adaptation to various installation requirements without requiring multiple different housing designs.
2Reliability
If a cable wall bushing provides sealed enclosures for cables, then protection against moisture and dirt is improved, but the ease of assembly and disassembly for maintenance or reconfiguration is reduced
Solution Approach 1:
The closure component is divided into multiple separable sections corresponding to individual cable openings. Each section can be independently removed or retained, allowing selective access to specific cable passages while maintaining sealed enclosures for others. This enables maintenance or reconfiguration of individual cables without compromising the overall sealing integrity of the bushing.
Solution Approach 2:
The closure component can be completely removed from the housing when full access to all cable openings is required. This extraction capability allows for comprehensive maintenance, inspection, or reconfiguration of all cables passing through the bushing, while the housing structure itself remains intact and can be quickly resealed by reattaching the closure component.
