Profiled Metal Bracket with Convex Elbow for Discreet Cable Tray Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable tray support brackets lack aesthetic appeal while being visible and cumbersome, failing to provide discreet fixing solutions for both walls and ceilings.
Innovation Solution
A profiled metal bracket with a convex bottom at the elbow and a fixing accessory that masks the openings and fastening members, allowing for compact and discreet installation on ceilings or walls, using a bead to close the space between returns and end pieces for a finished appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional brackets with visible openings and fastening members are used, then the cable tray can be securely fixed, but the appearance quality deteriorates due to visible fastening elements
Solution Approach 1:
The invention extracts the fastening members and openings from the visible exterior by using a cover element that completely encloses the bracket body. The fastening members are positioned inside the bracket body rather than on the exterior, and the cover element with its own fastening system hides all visible fastening elements, achieving a smooth appearance while maintaining secure fixing.
Solution Approach 2:
The cover element is designed to envelop and hide the bracket body containing the cable tray. The cover element acts as an outer shell that nests around the functional components, concealing the openings and fastening members within its structure while providing a finished aesthetic appearance.
2Shape
If the bracket structure is made compact and discreet, then the appearance quality improves, but the ease of manufacture deteriorates due to complex profiled metal element design
Solution Approach 1:
The invention divides the bracket system into separate modular components: a profiled metal element for structural function and a cover element for aesthetic enclosure. This segmentation allows each component to be manufactured independently using standard processes, avoiding the need for complex integrated manufacturing while achieving a compact overall appearance when assembled.
3Volume of moving object
If the returns are positioned on the inner side of the side walls, then the bracket becomes more compact, but the ease of operation deteriorates due to reduced access for fastening
Solution Approach 1:
The invention resolves the accessibility issue by moving the fastening operation to a different dimensional space. The cover element provides access to the cable tray through its own fastening system operated from the exterior, eliminating the need to access the inner side of the side walls. The returns remain positioned on the inner side for compactness, while the cover element's fastening members operate in the external dimension.
