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 the dynamics principle by incorporating a pivot portion that enables the fixing member to rotate between a first position (engaged with the retainer) and a second position (disengaged). This dynamic movement allows the mechanism to transition between locked and unlocked states, enabling repeated assembly and separation operations while maintaining reliability through controlled mechanical motion.
Solution Approach 2:
The patent segments the connecting device into distinct functional components: an actuating retainer with retaining sections, a fixing member with a pivot portion, and pin connection means. This segmentation allows each component to perform its specific function independently, improving the overall effectiveness for repeated operations by enabling the fixing member to pivot and disengage cleanly from the retainer.
2Strength
If the fixing member is firmly engaged with the retainer, then secure connection is achieved, but difficult to separate without excessive force
Solution Approach 1:
The dynamic pivot mechanism allows the fixing member to rotate from an engaged position (providing strong connection) to a disengaged position (enabling easy separation). The pivot portion acts as a fulcrum, allowing user force applied to the handle to generate sufficient moment to overcome the engagement force and release the connection without requiring excessive pulling force.
Solution Approach 2:
The patent introduces rotational movement as an additional dimension to the linear engagement relationship. Instead of only pulling the fixing member directly away from the retainer, the user can rotate the fixing member about the pivot portion, creating a leveraged motion that easily overcomes the engagement force and achieves separation.
3Stability of the object's composition
If the actuating retainer and fixing member are rigidly connected, then structural stability is improved, but the device cannot achieve quick release function
Solution Approach 1:
The patent replaces rigid connection with a pinned connection that allows controlled rotation. The pin connection means provides a stable hinge point that maintains structural integrity during engagement, while simultaneously allowing the fixing member to pivot for release. This dynamic connection achieves both structural stability and quick release functionality.
Solution Approach 2:
The pin connection acts as an intermediary element between the actuating retainer and the fixing member. It provides a stable connection point that maintains structural stability while enabling the necessary rotational movement for quick release, serving as a mediator that reconciles the conflicting requirements of rigidity and mobility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates repeated and efficient assembly and separation of objects by allowing limited sliding or rotational movement, ensuring secure connection and easy release with minimal manual effort.
Implementation Method 1
an elastic element, which has an end limited in place by the actuating retainer and another end pressed against the fixing member... the actuating retainer and the fixing member can move relative to each other within a limited range and then return to their respective original position under the elastic force of the elastic element
Implementation Method 2
the push of the second push section against the third object causes a lever displacement, a rotational displacement, or a limiting displacement of the quick release connecting device
Implementation Method 3
the push of the second push section against the third object causes a lever displacement, a rotational displacement, or a limiting displacement of the quick release connecting device

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.
