Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional quick release buckles require two steps for separation, are prone to accidental disengagement under pulling forces, and may suffer from reduced adhesion over time due to debris accumulation, posing safety risks during diving operations.
Innovation Solution
A quick release buckle design featuring a male member with elastic legs and a U-shaped part connected by a pulling member, allowing for single-step disassembly and enhanced connection security through elastic deformation, with features like guide blocks and slots for precise alignment and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the male member is designed with elastic legs that can be pressed inward to release the locking part, then the disassembly operation becomes simple, but the male member becomes prone to accidental disengagement under pulling forces
Solution Approach 1:
The patent inverts the traditional release mechanism by making the release action occur automatically when pulling force is applied in the normal direction. Instead of requiring deliberate pressing of the operation part to release, the pulling force itself triggers the leg deformation and locking part release, while simultaneous pulling activates the guide block-slot mechanism that prevents accidental disengagement
Solution Approach 2:
The guide block and guide slot serve as intermediary elements that mediate between the pulling force and the locking mechanism. When pulling force is applied, the guide block moves along the guide slot, which controls the timing and manner of leg deformation, ensuring that release only occurs when intentional pulling is applied while preventing release from lateral or accidental forces
2Strength
If the tongue of the male buckle is made more exposed for tighter locking, then the joint strength is improved, but users need to apply more force during assembly and disassembly
Solution Approach 1:
The patent employs dynamic leg structures that can deform elastically under load. During normal connection, the legs maintain a locked position providing strong joint strength. During disassembly, when pulling force is applied, the legs dynamically deform to release the locking part, reducing the force needed for disassembly compared to rigid tongue designs
Solution Approach 2:
The tongue is segmented into multiple functional parts: the main body providing structural strength, elastic legs providing locking and release functionality, and guide blocks providing controlled movement. This segmentation allows each part to optimize its function - the main body can be robust for strength while the legs and guide blocks enable easy operation
3Reliability
If conventional buckles require two steps for separation (pressing operation part then pulling out), then the locking mechanism is secure, but the disassembly process becomes time-consuming and complex
Solution Approach 1:
The patent merges the release action and the disassembly action into a single pulling motion. The guide block-slot mechanism ensures that when the user pulls the male member outward, this single action simultaneously releases the locking part from the locked part and separates the members, eliminating the need for separate pressing and pulling steps while maintaining secure locking
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
Enables secure, single-step assembly and disassembly while maintaining a tight connection under pulling forces or weight, reducing the risk of accidental release and improving operational convenience in emergency conditions.
Implementation Method 1
the two legs are deformed inward and elastically when the U-shaped part is pulled along the pull-out direction of the male member. Thus the male member is pulled out of the female member
Implementation Method 2
While a force in the pull-out direction of the male member being applied to and/or weight of an object connected to the male member acted on the base of the male member, the two legs are deformed outward and elastically. Thus the connection between the male and female members is getting tighter

AI summary
A quick release buckle is revealed. The quick release buckle includes a male member, a female member and a pulling member. The male member consists of two symmetrical legs that can be deformed elastically and a U-shaped part disposed between the two legs. Two ends of one side of the U-shaped part with an opening are respectively connected to each of the two legs. The female member is inserted by and locked with the male member while the pulling member is connected to the U-shaped part of the male member. When users pull the pulling member out, two ends of the U-shaped part with the opening are deformed inward. Thus the two legs are further driven to be deformed inward. Therefore the male member is pulled out of the female member.
