Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional quick release buckle design is used with a central drive key requiring sliding movement, then locking and unlocking functions are achieved, but two different forces in mutually perpendicular directions are required and the structure becomes complex
Solution Approach 1:
The locking member is divided into a first locking part and a second locking part that can move independently relative to each other. The first locking part engages with the first connecting member while the second locking part engages with the second connecting member, allowing separate control of locking and unlocking functions to simplify the overall structure and reduce the forces required for operation.
Solution Approach 2:
The locking mechanism transitions from requiring forces in multiple perpendicular directions to a primarily axial movement system. The first and second locking parts move along the axial direction of the buckle, converting a complex multi-directional force requirement into a simpler unidirectional axial movement that is easier to operate.
2Productivity
If an improved pressing method is used for unlocking, then the unlocking mechanism is simplified, but the unlocked part needs to move for a long distance to detach from the locked part resulting in low unlocking efficiency
Solution Approach 1:
The locking mechanism uses a dynamic spring-based system where the first locking part is connected to the second locking part through a compressible spring. This allows the locking parts to move dynamically during unlocking, with the spring providing restoring force to return the mechanism to its locked state, thereby reducing the overall movement distance required for effective unlocking while maintaining operational simplicity.
3Reliability
If a single unlocking method is provided in the quick release buckle, then the structure is simple, but the buckle becomes unusable if that single method fails in emergency situations
Solution Approach 1:
The buckle incorporates multiple unlocking methods within a single device: (1) axial pulling of the first locking part to disengage from the first connecting member, (2) axial pushing of the second locking part to disengage from the second connecting member, and (3) rotational movement of the locking member. This multi-functional design ensures that if one unlocking method fails or is inaccessible, alternative methods remain available, significantly improving reliability in emergency situations without substantially increasing structural complexity.
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
The buckle achieves rapid and accurate locking and unlocking with minimal movement, enhancing efficiency and adaptability, allowing for quick strap shortening without affecting locking, and providing multiple unlocking methods to prevent failure due to single method failure.
Implementation Method 1
the reset mechanism is a compression spring; the compression spring includes a first end abutted against one end of the track and a second end abutted against an inner part of the first connecting member
Implementation Method 2
the reset mechanism is a tension spring; the tension spring includes a first end fixedly connected to one end of the track and a second end fixedly connected to an inner part of the first connecting member
