Clamp Closure Flap Joint for Reliable Pin Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamps lack a material-saving and structurally simple yet reliable closure mechanism, which is essential for securely holding elongate objects while minimizing material usage and design complexity.
Innovation Solution
A clamp design featuring a closure flap that pivots through a passage opening to form a joint with a locking pin, utilizing an elastic ring to secure the flap in place, allowing for a compact and reliable closure mechanism with reduced complexity, where the flap catches the locking pin in a through-opening, preventing easy removal and allowing easy insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional locking mechanism is used to secure the closure flap, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines the locking flap and locking pin into a single integrated closure mechanism. The locking flap is formed as one piece with the closure element, eliminating the need for separate locking components. This merging reduces device complexity while maintaining reliable locking through the simple flap-pin interaction.
Solution Approach 2:
The invention extracts the essential locking function from complex traditional mechanisms and implements it through a simplified flap-pin system. By taking out only the necessary locking action and implementing it through a single flap element that pivots to engage with the pin, the mechanism achieves reliability without complexity.
2Device complexity
If a compact closure mechanism is used, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent employs parameter changes by providing adjustable positioning elements for the locking pin and flap. The pin can be positioned at different locations along its length, and the flap can be adjusted to different angular positions. This adjustability compensates for manufacturing tolerances and simplifies alignment requirements while maintaining the compact design.
3Reliability
If the locking pin is securely fixed in the clamp ring, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The invention applies dynamics by making the locking pin movable along the clamp ring circumference while maintaining secure fixation at the locked position. The pin can be easily inserted and removed by sliding it along the ring, but once positioned, it securely engages with the locking flap. This dynamic capability allows easy operation while maintaining reliability.
