Tolerance Compensation Mount With Deflecting Support Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for compensating tolerances between vehicle roof panels and support structures often deform when unscrewing, leading to irregular clearance and compromised seal functionality due to soft holding element clips, which can be deformed under elevated torque.
Innovation Solution
Incorporating a support wall with a deflection section that can be deflected along a diagonal line not perpendicular to the central longitudinal axis, allowing for controlled force distribution and maintaining stability, ensuring a defined overhang of the base element over the roof panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clips of the holding element are made soft to facilitate easy clipping into the roof panel, then the ease of operation is improved, but the clips can be easily deformed under elevated torque during unscrewing of the compensation element
Solution Approach 1:
The holding element is divided into functionally distinct parts: clips for engagement with the roof panel and a support wall for load bearing. The clips remain soft for easy installation while the support wall provides structural strength. This segmentation allows each part to be optimized for its specific function without compromise.
Solution Approach 2:
The load-bearing function is shifted from the clips (horizontal engagement) to the support wall (vertical support). By transferring the torque resistance function to a different structural element oriented perpendicular to the clip direction, the system achieves both easy clipping and high torque resistance.
2Adaptability or versatility
If the compensation element is unscrewed further to compensate for tolerances, then the adaptability is improved, but the clips deform causing irregular base element overhang
Solution Approach 1:
The holding element separates the tolerance compensation function (performed by the support wall and base element) from the positioning function (performed by the clips). This allows the base element to move vertically for tolerance adjustment while the clips maintain consistent horizontal positioning.
Solution Approach 2:
Tolerance compensation is achieved through vertical movement of the base element along the central longitudinal axis, while clip engagement remains in the horizontal plane. This dimensional separation ensures that tolerance adjustment does not affect the consistency of the base element's horizontal overhang.
3Strength
If the support wall has high stability to transmit forces in the direction of the central longitudinal axis, then the strength is improved, but the deflection section requires careful design to balance flexibility for installation
Solution Approach 1:
The support wall incorporates a deflection section that transitions from rigid to flexible behavior during installation. The deflection line creates a hinge effect that allows controlled bending during clipping, while the restored position after installation provides stable force transmission. This dynamic behavior resolves the contradiction between flexibility and rigidity.
Solution Approach 2:
The deflection section acts as a flexible element within the support wall structure, allowing controlled deformation during installation while maintaining overall structural integrity. This flexible section enables the rigid support wall to adapt during installation without compromising its load-bearing capacity.
