Construction Vehicle Panel Fastener for Tool-Free Vibration Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction vehicles face challenges in quickly and easily coupling and decoupling panels without additional tools, while also needing to withstand high vibration levels that can cause rattling and component failure.
Innovation Solution
A fastening member with a movable lock stud and a ring assembly featuring inclined and parallel tabs that switch between locked and unlocked positions, providing a secure clamping force without requiring additional tools and enhancing vibration resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fasteners are used to couple panels, then the panels can be removably coupled, but the coupling and decoupling process requires additional tools and time
Solution Approach 1:
The fastening member is designed to be operated without additional tools. The release button allows the lock stud to be actuated manually, enabling the ring assembly to detach from the seating portion without requiring any external tools or fixtures.
Solution Approach 2:
The fastening member incorporates a movable lock stud that can transition between locked and unlocked positions. The ring assembly is designed to be movable relative to the vehicle component, allowing quick insertion and removal through dynamic movement rather than static fastening.
2Ease of operation
If simple fasteners are used for quick coupling, then tool-free operation is achieved, but sufficient clamping force to resist vibration may not be provided
Solution Approach 1:
The ring assembly features a curved or rounded geometry that complements the seating portion shape. This curved design allows the ring to be easily inserted and rotated into the locked position while providing uniform contact pressure around the lock stud, enhancing vibration resistance.
Solution Approach 2:
The fastening member combines multiple functions into a single integrated component: the ring assembly serves as both the coupling element and the clamping mechanism, while the lock stud provides both positioning and locking functions. This merging eliminates the need for separate fasteners and maintains structural integrity under vibration.
3Reliability
If multiple tabs are added to the ring assembly, then clamping force and vibration resistance are improved, but device complexity increases
Solution Approach 1:
The ring assembly is segmented into multiple tabs (first tabs and second tabs) that can independently engage with corresponding features on the vehicle component. This segmentation distributes the clamping force across multiple contact points, enhancing vibration resistance while maintaining a relatively simple overall structure.
Solution Approach 2:
Different tabs on the ring assembly have different orientations and functions: the first tabs provide primary clamping force, while the second tabs provide additional stabilization. This local differentiation of tab properties optimizes the overall performance without requiring a completely complex design.

AI summary
A construction vehicle includes a panel removably coupled to a vehicle component and fastening member for removably coupling the panel to the vehicle component. The fastening member includes a main body having a lock stud that is movable to switch the fastening member between a locked position and an unlocked position. The fastening member also includes a ring assembly. The ring assembly defines a first portion and a second portion. The first portion includes a base portion and one or more first tabs. The one or more first tabs are inclined relative to the base portion. The first portion further includes one or more second tabs parallel to the base portion. Further, the one or more first tabs and the one or more second tabs together define a seating portion for receiving the lock stud.
