Tiltable Cable Bushing for Angled Wall Passages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable bushings lack the ability to efficiently accommodate cables passing through obliquely angled passage openings in walls or floors, limiting their tilting range and accessibility.
Innovation Solution
A cable bushing with a tiltably mounted design, featuring a central axis that can be inclined by at least 10° relative to the surface normal, allowing for tilting between two end positions and a middle position, enabling the bushing to be tilted up to 45° in any direction, and utilizing a ball joint or knee joint bearing for maximum angular range, along with a soft material contact surface for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional fixed cable bushing is used, then the installation is simple and structure is straightforward, but the bushing cannot accommodate obliquely angled passage openings
Solution Approach 1:
The bushing is made tiltable relative to the flange part through a bearing connection, allowing the bushing center axis to change its angle relative to the surface normal. This dynamic adjustment capability enables the bushing to accommodate both straight and obliquely angled passage openings, directly resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If the bushing is made tiltable to accommodate angled openings, then adaptability improves, but the mounting complexity increases
Solution Approach 1:
The bearing connection enables the bushing to tilt within a specific angular range (at least 10° inclination from surface normal) while maintaining a secure mounting. This dynamic capability allows the bushing to adapt to various passage angles without requiring complex adjustment mechanisms, achieving a balance between tilting range and mounting simplicity.
Solution Approach 2:
The bearing is designed to allow tilting within a defined angular parameter range, with the bushing center axis capable of inclining by at least 10° relative to the surface normal. This parameter-based design provides predictable and controlled adaptability while maintaining structural simplicity.
3Adaptability or versatility
If the bushing is tilted at an angle, then accessibility for angled cables improves, but sealing reliability may be compromised
Solution Approach 1:
A soft material contact surface is provided between the flange part and the bushing, creating a flexible sealing interface. This soft material can deform to maintain effective sealing contact even when the bushing is tilted at angles up to 45°, thus preserving sealing reliability while enabling cable accessibility through angled openings.
