Vehicle Suspension Device With Opposing Locking Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspension devices for attaching heavy components to vehicle structures are inefficient for quick and ergonomic mounting and demounting, particularly when access is limited to different directions during assembly and service operations.
Innovation Solution
A suspension device with a first and second bracket, and locking arrangements that can be screwed into a common locking sleeve from opposite sides, allowing for clamping and easy separation, enabling attachment and disassembly from two different directions, and providing a stiffer connection by applying clamping and pressing forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional suspension devices are used for mounting components from above, then assembly is possible from the intended direction, but demounting becomes difficult when access is limited to underneath the vehicle
Solution Approach 1:
The locking mechanism is divided into two separate locking arrangements (first and second locking arrangements) that can be operated independently from opposite sides of the suspension device. This segmentation allows the assembly to be mounted from above while demounted from underneath by releasing only the lower locking arrangement, resolving the contradiction between mounting direction and demounting accessibility.
Solution Approach 2:
The suspension device incorporates a universal locking system where both upper and lower locking arrangements connect to a common locking sleeve, enabling the same device to be securely mounted from above during assembly and efficiently demounted from underneath during service operations. This multi-functionality allows the device to adapt to different operational phases and access conditions.
2Reliability
If heavy components are attached to vehicle structure, then secure mounting is achieved, but the attachment process becomes time consuming and ergonomically unsound
Solution Approach 1:
The locking arrangements are pre-positioned on the suspension device body, and the brackets are designed with predetermined engagement features that align with the locking sleeve. This preliminary arrangement allows for rapid connection without complex alignment procedures, improving productivity while maintaining secure attachment through the robust locking mechanism.
Solution Approach 2:
The suspension device incorporates movable locking arrangements that can be quickly engaged and disengaged from opposite sides of the device. The locking elements are designed to move smoothly within the locking sleeve, enabling fast mounting and demounting operations while maintaining reliable secure attachment when locked.
3Strength
If rigid connection is used between brackets, then load transfer is improved, but the device becomes more complex and harder to assemble
Solution Approach 1:
The locking arrangements are merged with the bracket structure through integrated mounting features, where the locking elements directly engage with the brackets via the common locking sleeve. This merging creates a stiff, rigid connection for improved load transfer while avoiding additional separate components that would increase device complexity.
