Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting brackets for cable routing ducts face challenges in accommodating deviations in building wall alignment, requiring additional underlayment and lacking precision in adjustment mechanisms, which can lead to instability and displacement under impact.
Innovation Solution
An adjustable mounting bracket with U-shaped telescopic elements that can be precisely aligned and locked using a fastening screw, providing high static friction and stability, and a pivotable angle piece for adjusting to wall deviations without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mounting brackets are used to accommodate wall deviations, then additional underlayment components are required, but the device complexity increases and assembly becomes more difficult
Solution Approach 1:
The mounting bracket incorporates telescopic elements that can dynamically adjust their length to accommodate deviations in wall alignment. The first and second telescopic elements can be displaced relative to each other, allowing the bracket to adapt to various wall conditions without requiring additional underlayment components or complex assembly procedures.
2Reliability
If telescopic elements are clamped with high pretensioning force to prevent displacement, then stability improves, but the risk of deformation and damage to the cable routing duct increases
Solution Approach 1:
The clamping mechanism is segmented into multiple interaction points between the first and second telescopic elements. The legs of the second telescopic element extend in the direction of the base of the first telescopic element, creating multiple contact surfaces that distribute the clamping force. This segmentation allows stable clamping with lower individual pretensioning forces, reducing the risk of deforming or damaging the cable routing duct.
3Manufacturing precision
If the telescopic elements are arranged close together to minimize contact surface, then precision alignment is improved, but the bracing effect against displacement is reduced
Solution Approach 1:
The second telescopic element is nested within the first telescopic element, with the legs of the second element extending toward the base of the first element. This nesting arrangement creates a hollow profile structure that provides both precise alignment through the fitted interaction of the elements and effective bracing against displacement through the geometric interlocking of the nested configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures secure and stable mounting of cable routing ducts by allowing precise alignment and adjustment to wall irregularities, preventing displacement and facilitating easy assembly, even in complex spatial conditions.
Implementation Method 1
a very high level of static friction can be achieved there. As a result, it is not to be feared that impacts or blows against the cable routing duct that is ultimately installed will lead to a displacement of the telescopic elements in relation to one another.

AI summary
The bracket (10) has U-shaped telescopic elements (16, 18) movably arranged to each other. The telescopic elements include two legs extending from a base in a cross-section portion. The legs of one of the telescopic elements extend in direction of the base of the other telescopic element, where the telescopic elements partially form a hollow section. Distance between mutually facing inner surfaces of the legs of the latter telescopic element corresponds to distance between mutually opposite outer surfaces of the legs of the former telescopic element.
