Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting elements for control cabinet housings suffer from shifting and limited tolerance accommodation due to the pivoting movement of clamping elements, complicating assembly and accommodating manufacturing tolerances.
Innovation Solution
A mounting element with a clamping element adjustable in the longitudinal direction via a drive mechanism, guided by a linear guide, allowing flexible adaptation to cabinet housing tolerances and preventing shifting during clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clamping element pivots relative to the mounting rail according to the toggle lever principle, then the mounting element can be clamped in the control cabinet housing, but the mounting element shifts during clamping
Solution Approach 1:
The clamping element is made adjustable in the longitudinal direction of the mounting rail through a drive mechanism, allowing dynamic adaptation during clamping. This longitudinal adjustability compensates for manufacturing tolerances and prevents shifting by enabling the clamping element to move along the mounting rail's length rather than pivoting, thus maintaining position accuracy while achieving reliable clamping.
2Adaptability or versatility
If the clamping element pivots relative to the mounting rail, then the mounting element can accommodate the control cabinet housing, but it can only accommodate manufacturing tolerances to a very limited extent
Solution Approach 1:
The drive mechanism enables the clamping element to adjust longitudinally along the mounting rail, providing dynamic adaptability to manufacturing tolerances. This adjustment capability allows the mounting element to accommodate variations in the distance between opposing contours of the control cabinet housing while maintaining precise positioning, thereby significantly improving tolerance accommodation compared to the fixed pivot point in traditional toggle lever designs.
3Adaptability or versatility
If the clamping element is adjustable in the longitudinal direction via a drive mechanism, then the mounting element can adapt to manufacturing tolerances, but the device complexity increases
Solution Approach 1:
The drive mechanism replaces the traditional toggle lever pivoting system with a linear adjustment system. This substitution eliminates the complex pivoting motion and associated tolerances while providing straightforward longitudinal adjustability. The drive mechanism can be implemented using simple threaded connections or linear guides, reducing overall device complexity compared to the pivoting mechanism while achieving the desired adaptability.

Function Achieved in This Case
Ensures process-reliable clamping within control cabinet housings, accommodating manufacturing tolerances without tilting or obstructing assembly, and enabling secure electrical contact through spring elements.
Implementation Method 1
The slide can have a spring constant or elasticity suitable for absorbing a clamping force. In one embodiment, the slide can have a rigid slide plate onto whose edge facing away from the mounting rail a spring element for absorbing the clamping force is mounted, the spring element having a suitable spring constant or elasticity for this purpose.
