Cargo Tie-Down Clip Eliminates Loop Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo tie-down assemblies in motor vehicles fail to effectively eliminate free play, vibration, and noise when not in use, as they lack a mechanism to securely engage the tie-down loops.
Innovation Solution
A cargo tie-down assembly featuring a clip with a grooved projection that engages the tie-down loop, combined with resilient mounting lugs for secure attachment to the base, limits free play and vibration by securely fastening the clip over the base, using a cylindrical aperture and arcuate section design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cargo tie-down assembly uses a simple base with tie-down loop without additional components, then the device complexity is low, but free play, vibration, and noise cannot be eliminated
Solution Approach 1:
The base is divided into functional segments: a cylindrical aperture for loop reception, a sleeve-like portion for structural support, and an opening for clip engagement. This segmentation allows each part to perform its specific function while collectively eliminating free play without excessive complexity
Solution Approach 2:
A clip is introduced as an intermediary component between the base and the tie-down loop. The clip carries a projection that engages the loop within the cylindrical aperture, acting as a mediator that secures the loop and eliminates free play, vibration, and noise while maintaining manageable device complexity
2Reliability
If the tie-down loop is left unsecured in the base, then the ease of operation is high, but vibration and noise occur during vehicle operation
Solution Approach 1:
The clip is designed with resilient mounting lugs that automatically snap over the edges of the base when the clip is placed on the base. This self-service mechanism secures the clip to the base without requiring additional fastening operations, eliminating vibration and noise while maintaining ease of operation
Solution Approach 2:
The resilient mounting lugs change their physical state from flexible to locked position when snapped over the base edges. This parameter change allows the clip to transition from an easily installable component to a securely fixed element that eliminates vibration and noise during vehicle operation

AI summary
A cargo tie-down assembly is provided. The cargo tie-down assembly includes a base, a tie-down loop carried by the base, and a clip carried on the base. The clip engages a portion of the tie-down loop held in the base to limit free play and vibration of the tie-down loop with respect to the base.
