One-Way Locking Rope Assembly with Presser Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing dust-proof covers on yachts or jet skis during transportation are inefficient, as they often fail to prevent the covers from being blown away and can jam, making it difficult to release the rope loop assembly.
Innovation Solution
A fast looping-up and releasing rope loop assembly with two one-way locking devices and a buckle, allowing for efficient tightening and release, featuring a metal slotted plate and a presser that can be depressed to release the rope when jammed, ensuring secure attachment and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a one-way locking device is used to secure the rope loop, then the rope loop can be tightened effectively, but it may get jammed and become difficult to release
Solution Approach 1:
The release mechanism is segmented into two independent parts: a presser for initial release and an operation arm for complete release. This segmentation allows the system to first relieve tension through the presser, then fully release through the operation arm, avoiding the jamming problem of single-step release mechanisms.
Solution Approach 2:
The presser performs a preliminary release action by depressing to initially release the rope, creating a buffering space before the operation arm completes the full release. This preliminary action prevents the operation arm from encountering resistance during release.
2Reliability
If a sufficient length of rope is used to entangle around fixation bars, then the cover can be secured during transportation, but the entangling process becomes elaborate and time-consuming
Solution Approach 1:
The rope loop assembly uses a dynamic tightening mechanism where pulling the rope causes it to be withdrawn in a single direction through the one-way locking device, automatically looping up the sack opening without requiring manual entangling around multiple fixation bars.
Solution Approach 2:
The invention extracts the complex entangling process and replaces it with a simple pull-to-tighten mechanism. The rope is threaded once through the one-way locking device and sack opening, eliminating the need to entangle around multiple fixation bars while maintaining securing effectiveness.
3Reliability
If the rope is over-tightened during transportation, then the cover is securely fastened, but it becomes difficult to release subsequently
Solution Approach 1:
The presser provides beforehand cushioning by being designed to depress and initially release the rope when the operation arm is actuated. This cushioning action relieves over-tightening tension before the complete release occurs, preventing the release mechanism from being blocked by excessive tension.
Solution Approach 2:
The presser acts as an intermediary element between the operation arm and the rope release mechanism. When the operation arm is actuated, the presser first depresses to partially release the rope, serving as a mediator that gradually reduces tension before full release, preventing jamming from over-tightening.

AI summary
A fast looping-up and releasing rope loop assembly includes two one-way locking devices, at least one band, and a buckle. The one-way locking device includes a body constituted by a base and a cover. The one-way locking device allows the pull rope to extend therethrough and to move with respect thereto along a single direction. By inserting the pull rope through a rope entry opening of the base of the one-way locking device and further extending the rope around a rotary disk and a rotary wheel arranged inside the locking device and extending out of the locking device, the one-way locking device that locks the movement of the rope in an opposite direction is completed. When the rope is jammed due to excessive tightening, a presser of the buckle is depressed to release the one-way locking device from the jamming condition so that efficient loop-up and release can be realized.
