Rotating Pivot Retaining Device for Vehicle Body Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retaining devices for vehicle body parts, such as snap-engaging devices, are not suitable for repeated assembly and disassembly without risk of damage, and screws are costly and time-consuming.
Innovation Solution
A retaining device with a box-like element, pivot, and elastically deformable wings that can snap-engage and retract, allowing easy assembly and disassembly by rotating the pivot between two angular positions, ensuring secure connection and safe disconnection without damaging the parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If snap-engaging retaining devices are used, then assembly speed is improved, but the device cannot be disassembled without risk of damage
Solution Approach 1:
The retaining device incorporates a pivot mechanism that can rotate between a first angular position (for assembly/snap-engagement) and a second angular position (for disassembly/release). This dynamic transformation allows the device to switch between locked and unlocked states, enabling both rapid assembly and damage-free disassembly through controlled rotational movement of the pivot and associated wings.
2Reliability
If screws are used, then reusability and reliability are improved, but assembly time and cost increase
Solution Approach 1:
The retaining device is divided into functional segments: a box-like element, a pivot, and elastically deformable wings. The wings can independently deform and retract, allowing the device to achieve secure engagement through snap-action while enabling quick release through pivot rotation. This segmentation eliminates the need for time-consuming screw operations while maintaining reusability.
Solution Approach 2:
The device utilizes elastic deformation of the wings as a key parameter change mechanism. During assembly, the wings deform elastically to pass through the opening and then snap into a locked position. During disassembly, the pivot rotation causes the wings to retract elastically, releasing the lock. This parameter change (elastic deformation) enables both rapid assembly and damage-free disassembly.
