Pivoting Webbing Clamp for Flat, Secure Strap Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing web-adjustment clamps are bulky, prone to webbing twisting and puckering, and do not securely lock or allow for quick adjustments, often unlocking inadvertently when pulled in certain directions.
Innovation Solution
A compact web-adjustment clamp design featuring a main body with lateral channels, a fold channel, and an exit channel, along with a pivotally coupled locking door that securely locks webbing in place, preventing twisting and puckering, and enabling easy adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If known webbing clamps are used, then webbing can be adjusted and secured, but the clamps become bulky and large
Solution Approach 1:
The clamp body is divided into distinct functional segments: a base portion for structural support, a door portion for locking action, and integrated channels for webbing routing. This segmentation allows each component to perform its specific function efficiently while maintaining a compact overall structure, eliminating the need for bulky separate components found in traditional clamps.
2Reliability
If known webbing clamps are used, then webbing can be locked down, but the webbing twists, puckers, or moves
Solution Approach 1:
The locking mechanism operates in a dimension perpendicular to the webbing tension direction. The door rotates on a pivot axis that is perpendicular to both the webbing and the locking direction, allowing the locking ledge to engage the webbing from the side rather than from the front. This dimensional change prevents webbing distortion while maintaining secure locking.
Solution Approach 2:
The fold channel is pre-configured with a specific geometry that guides the webbing into a folded configuration before it reaches the locking mechanism. This preliminary folding action ensures the webbing enters the clamp in a controlled, flat state, preventing twisting and puckering before the locking action occurs.
3Ease of operation
If known webbing clamps are used, then webbing can be adjusted, but quick and easy adjustment is precluded
Solution Approach 1:
The door is designed to rotate dynamically on a pivot rather than requiring manual assembly or complex locking steps. The rotational movement allows the door to be quickly opened for adjustment and securely closed for locking with a single motion, dramatically reducing adjustment time compared to traditional clamps that require multiple steps or tools.

AI summary
A web-adjustment clamp includes a main body including a first lateral channel, a second lateral channel, a fold channel, and an exit channel. The first lateral channel, the second lateral channel, the fold channel, and the exit channel are configured to accept, have passed through, and retain a first webbing. The fold channel may be further configured to accept, have passed through, and retain a second webbing. In at least one embodiment, a locking door is pivotally coupled to the main body. The locking door is configured to be moved between an open position and a closed position. The first webbing is adjustable in relation to the web-adjustment clamp when the locking door is in the open position, and locked in place when the locking door is in the closed position.
