Cable Duct Upper Part Asymmetrical Profiles Flush Offset Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable routing ducts require multiple variants to achieve flush and offset mounting positions, increasing manufacturing and distribution costs and the number of parts during assembly, which is unsatisfactory.
Innovation Solution
A cable routing duct with asymmetrical lid-retaining profiles on the lower and upper parts, featuring differently dimensioned geometric structures on both sides, allowing a single upper part to achieve either flush or offset mounting positions by rotating the upper part 180°, facilitated by leg elements of varying lengths interacting with lid holding profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two different mounting variants are offered to meet different customer requirements for flush or offset positions, then customer needs are satisfied, but manufacturing and distribution costs increase and the number of parts during assembly increases
Solution Approach 1:
The patent applies asymmetry by designing the upper part with a symmetrical body but asymmetrical attachment means on its underside - specifically, two different attachment profiles (first and second attachment profiles) that are mirror images of each other. This allows a single upper part to achieve both flush and offset mounting positions by rotating it 180 degrees, eliminating the need for separate variants while maintaining design versatility
Solution Approach 2:
The upper part is designed as a universal component that can serve multiple mounting configurations. By incorporating both attachment profiles on the same upper part and enabling 180-degree rotation, the single component performs the function of what would traditionally require two different components, thereby reducing part complexity while maintaining adaptability
2Adaptability or versatility
If two different mounting variants are offered for flush and offset positions, then customer requirements are met, but manufacturing and distribution costs increase
Solution Approach 1:
The patent merges the functionality of two separate upper parts into a single unified component. The upper part incorporates both the first attachment profile and the second attachment profile on opposite sides, allowing it to be manufactured as one piece rather than two separate components, thereby reducing manufacturing complexity and distribution costs while maintaining both mounting options
3Adaptability or versatility
If asymmetrical support structures are used to achieve different mounting heights, then different positions are possible, but the structure becomes more complex and requires significant development work
Solution Approach 1:
The patent utilizes asymmetry in the attachment profiles - the first and second attachment profiles are designed as mirror images with different geometric configurations. This asymmetrical design enables the upper part to achieve different mounting positions (flush or offset) through simple 180-degree rotation, without requiring complex asymmetrical support structures throughout the entire duct system

AI summary
The channel has a U-shaped lower part (2), and a U-shaped upper part (1) at which two geometrically differently formed form profiles are designed. Two geometrically differently formed U-shaped cover retaining profiles are formed at the lower part and include inner brackets (26, 43), bases (25, 44), outer brackets (21, 40) and support strips (12, 34) that cooperate with the retaining profiles. The form profiles and the retaining profiles are cooperated with each other. The form profiles have upper side elements (18, 30) that run up to support strips and are variably long.
