Luggage Wheel Extractable Assembly with Rapid Engaging Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly groups for luggage wheels are difficult to disassemble quickly and safely, requiring significant time and effort, especially when trying to minimize space for loading luggage into a car.
Innovation Solution
An extractable assembly group featuring a rapid engaging mechanism with a slider, pushbutton, and elastic recall element allows for easy and safe disassembly and reassembly of the fork from the bracket, using a slider that slides along the bracket and support to transition between engaging and unengaging positions, facilitated by a cover to maintain the mechanism's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to couple the fork to the bracket, then the connection is fixed and safe, but the disassembly process is time-consuming and difficult
Solution Approach 1:
The engagement mechanism is divided into separate functional components: a slider element, an elastic recall element, and engagement protrusions. This segmentation allows the complex fastening function to be broken down into simple sliding and spring-loaded engagement actions, enabling quick release while maintaining secure connection during use.
Solution Approach 2:
The mechanism transitions from a static screw connection to a dynamic system where the slider can move between engaged and disengaged positions. The elastic recall element provides dynamic response, automatically returning the slider to the engaged position after release, ensuring reliable re-engagement without manual intervention.
2Device complexity
If traditional screw mechanisms are used, then the structure is simple, but the operation becomes difficult and slow
Solution Approach 1:
The elastic recall element performs the function of automatically returning the slider to the engaged position after release, eliminating the need for manual manipulation to reset the mechanism. The system serves itself by using the spring's stored energy to ensure proper re-engagement, reducing user effort and complexity.
Solution Approach 2:
The traditional multi-turn screw threading mechanism is replaced with a sliding mechanism actuated by elastic energy. This substitution transforms the operation from rotational mechanical threading to linear sliding motion with spring assistance, dramatically reducing the number of operations required for assembly and disassembly.
3Productivity
If the fork can be easily removed, then the loading process is faster, but the risk of dangerous unengagement increases
Solution Approach 1:
The elastic recall element is pre-loaded to store energy that will be released to ensure positive engagement of the fork with the bracket. This beforehand cushioning of spring energy ensures that when the slider is released, the engagement action is forceful and secure, preventing accidental unengagement during the quick-release process.
Solution Approach 2:
The slider acts as an intermediary element between the user's release action and the fork-bracket connection. It mediates the transition from engaged to disengaged state through controlled sliding motion, and then mediates the automatic re-engagement through spring force, providing a buffer that prevents direct, potentially dangerous, sudden movements of the fork.
