Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick release mechanisms are not effective for convenient and repeated assembly and separation of circuit boards, drawers, or windows from their corresponding racks, chassis, or cabinets.
Innovation Solution
A quick release connecting device featuring an actuating retainer and a fixing member with a pivot portion and pin connection means, allowing limited sliding or rotational movement, and an elastic element for easy engagement and disengagement, enabling repeated assembly and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a quick release mechanism is provided on the circuit board or rack, then convenient assembling and fastening is enabled, but the mechanism is not effective for repeated assembly and separation
Solution Approach 1:
The patent applies dynamics by making the fixing member movable relative to the actuating retainer through pin connection means. The fixing member can rotate about a pivot portion and slide within limited ranges, transforming a static connection into a dynamic one that enables both secure engagement and easy release through controlled movement
Solution Approach 2:
The patent segments the connecting device into two main components: the actuating retainer and the fixing member. This segmentation allows independent movement of each component, with the fixing member able to rotate and slide relative to the retainer, facilitating repeated assembly and separation operations
2Stability of the object's composition
If the fixing member is rigidly fixed to the actuating retainer, then structural stability is maintained, but easy disengagement cannot be achieved
Solution Approach 1:
The patent replaces rigid fixed connection with dynamic movable connection through pin means that allow the fixing member to rotate about a pivot portion and slide within the actuating retainer. This dynamic connection maintains structural stability during normal operation while enabling easy disengagement through controlled movement
Solution Approach 2:
The pin connection means acts as an intermediary between the fixing member and the actuating retainer. It provides both structural support for stability and controlled movement for easy disengagement, mediating between the conflicting requirements of rigidity and mobility
3Ease of operation
If a movable connection is provided between the actuating retainer and fixing member, then easy separation is enabled, but device complexity increases
Solution Approach 1:
The patent implements a relatively simple movable connection where the fixing member rotates about a pivot portion and slides within limited ranges relative to the actuating retainer. This dynamic connection achieves easy separation without requiring complex mechanisms, maintaining simplicity while enabling the desired functionality

AI summary
A quick release connecting device includes an actuating retainer and a fixing member movably assembled to the actuating retainer. The fixing member includes a pivot portion and a pivot member movably mounted to the pivot portion; and the pivot member is coupled with a second object. The fixing member includes a limiting section and the pivot member includes a corresponding limiting section, such that the limiting section and the corresponding limiting section limit or stop each other at a specific location when the fixing member is moved or rotated. With these arrangements, the quick release connecting device can be applied to conveniently and repeatedly connect and separate a circuit board, a drawer, or a window to and from a corresponding rack, chassis, cabinet or window frame. The pivot member may be a pin that passes through a hole in the second object is retained by deformation of an end of the pin or by deformation of a portion of the second object.
