Dashboard Assembly Connector With Adjustable Anti-Play Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly parts for connecting a dashboard to a vehicle body allow play between components, leading to vibrations and noise due to imprecise adjustment and difficulty in easy assembly and disassembly.
Innovation Solution
A unidirectional adjustable assembly part with a male portion engaging the dashboard and a female portion engaging the vehicle body, featuring a hook-shaped design and toothed areas to prevent translational movement, allowing for precise adjustment and secure engagement, and an elastic stop for easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing assembly parts are used to connect dashboard to vehicle body, then assembly is simple, but play and vibrations occur due to imprecise adjustment
Solution Approach 1:
The male portion is designed with a hook-shaped free second end that can move perpendicular to the central plane, allowing dynamic adjustment during assembly. The unidirectional adjustable approaching movement between the female portion and body part enables precise positioning while maintaining structural simplicity.
Solution Approach 2:
The male portion extends in a longitudinal direction from the first end to the hook-shaped second end, creating a spatial configuration that allows adjustment in one dimension (approaching movement direction) while preventing movement in other dimensions through the hook shape and side walls with protuberances.
2Ease of operation
If existing assembly parts are used, then structure is simple, but disassembly is difficult once mounted
Solution Approach 1:
The elastic stop provides a dynamic solution where the dashboard can be easily pushed against it for disassembly, while the same elastic stop maintains secure engagement during normal operation. The unidirectional adjustable approach allows easy assembly by pushing the female portion toward the body part.
Solution Approach 2:
The assembly part is segmented into distinct functional elements: the male portion for dashboard engagement, the female portion for body part engagement with unidirectional adjustment, side walls with protuberances for lateral constraint, and an elastic stop for controlled disengagement. This segmentation allows each element to perform its specific function independently.
3Object-affected harmful factors
If existing assembly parts are used, then assembly is easy, but play generates vibrations and noise
Solution Approach 1:
The side walls are provided with openings that cooperate with protuberances on the male portion, creating localized constraint points that prevent translational movement without requiring complex overall structure. The hook-shaped second end provides localized engagement with the dashboard opening.
Solution Approach 2:
The toothed areas on the arms automatically engage with corresponding toothed areas on the body part to prevent translational movement in the opposite direction to the approaching movement, providing self-constraining functionality without additional components.
