Vehicle Upper Module Mounting with Lever-Lock Quick Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting systems for upper modules on vehicles require time-consuming bolting and nutting processes, making it difficult to easily attach and detach upper modules, particularly when switching between different types of modules.
Innovation Solution
A mounting unit that uses a lever-operated main rod and damper system to securely attach and detach upper modules from the underbody of a vehicle without the need for fastening bolts and nuts, allowing for quick and easy module changes by aligning the head of the main rod with the mounting bracket and using a cam mechanism to lock the module in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fastening bolts and nuts are used to mount the upper module, then the mounting is secure and reliable, but the attachment and detachment process becomes time-consuming and complex
Solution Approach 1:
The mounting system is divided into separate functional components: the mounting bracket with positioning holes, the main rod with head portion, and the operating lever. This segmentation allows each component to perform its specific function independently, enabling quick assembly and disassembly while maintaining secure mounting through the coordinated interaction of these segmented parts
Solution Approach 2:
The main rod is designed to be rotatable relative to the base, transforming from a static bolted connection to a dynamic lever-based mechanism. The operating lever rotates the main rod between a first position (mounting) and a second position (detachment), making the mounting process dynamic and controllable without requiring multiple fastening operations
2Stability of the object's composition
If multiple fastening points are used to secure the upper module, then the mounting stability is improved, but the alignment and positioning difficulty increases
Solution Approach 1:
The mounting bracket is pre-equipped with multiple positioning holes at predetermined locations before the mounting operation. This preliminary preparation eliminates the need for real-time alignment adjustments, as the operator simply needs to insert the head portion into any of the pre-positioned holes, thereby maintaining mounting stability while significantly improving alignment ease
Solution Approach 2:
The multiple positioning holes in the mounting bracket serve multiple functions: they provide various insertion points for the head portion, accommodate different upper module positions, and enable both secure mounting and easy detachment. This multi-functionality resolves the contradiction between stability and alignment ease by making the alignment process universal and straightforward
3Productivity
If a lever-operated main rod system is used instead of bolts and nuts, then the attachment and detachment speed is improved, but the device complexity increases
Solution Approach 1:
The operating lever is coupled to the main rod, merging the leverage mechanism with the mounting rod into a single integrated component. This combination allows the operator to utilize mechanical advantage through the lever while directly actuating the main rod, achieving fast attachment and detachment without requiring separate complex mechanisms for each function
Solution Approach 2:
The main rod's head portion is designed to be automatically caught and fixed by the mounting bracket when inserted into the positioning holes. This self-fixing mechanism eliminates the need for additional fastening components or complex locking mechanisms, thereby improving attachment speed while keeping the overall device complexity manageable
