Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for removing wishbones from motor vehicles are not adaptable to varying vehicle geometries, leading to suboptimal performance, easy slippage, and the need for multiple costly tools for different vehicle types.
Innovation Solution
A device with a lever, fastener, and position-adjustable engagement element, allowing optimal adaptation to the wishbone geometry, featuring a detachable and adjustable hook mechanism to facilitate the separation of the wishbone from the spring strut, and an elastic element to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-geometry lever is used for removing wishbones, then the device structure is simple, but it cannot adapt to different vehicle geometries and slips off easily
Solution Approach 1:
The lever device incorporates an adjustable engagement element that can be positioned at multiple locations along the lever arm, transforming a static fixed-geometry tool into a dynamic adaptable tool. This allows the same device to accommodate different vehicle geometries by adjusting the engagement point, directly resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The lever is designed with a universal structure that can serve multiple vehicle types through adjustment of the engagement element position. The same lever body can be used across different vehicle models by repositioning the engagement element, achieving multi-functionality without requiring multiple specialized tools for each vehicle type.
2Reliability
If multiple specialized levers are acquired for different vehicle types, then each lever is optimized for its specific vehicle, but the cost and storage space increase significantly
Solution Approach 1:
The lever device is designed as a universal tool that can be applied to multiple vehicle types through adjustment mechanisms. By incorporating an engagement element that can be repositioned along the lever arm, a single device replaces the need for multiple specialized levers, reducing both the quantity of tools required and the associated storage and cost burdens.
Solution Approach 2:
The lever device is segmented into adjustable components, particularly the engagement element that can be independently positioned. This segmentation allows the same lever body to be configured for different vehicle geometries, enabling one tool to perform the function of multiple specialized tools without requiring physical multiplication of the entire device.
3Adaptability or versatility
If the engagement element is made detachable and position-adjustable, then adaptability to different wishbone geometries improves, but the device complexity increases
Solution Approach 1:
The engagement element is designed with detachable and position-adjustable characteristics, allowing it to be reconfigured for different wishbone geometries. This dynamic capability enables the same engagement element to adapt to various configurations through simple repositioning or detachment, achieving high adaptability without requiring complex replacement mechanisms.
