Multi-Grip Driver Assist Strap With Anti-Slip Articulating Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver assist straps have limitations such as a single large grip, lack of anti-slip features, insufficient weight barrier, and kinking issues due to fittings, compromising safety and convenience.
Innovation Solution
A strap apparatus with multiple grips, constructed from non-slip materials and featuring an articulating joint to prevent kinking, with a greater weight barrier and improved fittings for secure attachment to cargo vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single large grip is used in existing driver assist straps, then the strap provides basic support function, but it becomes difficult to store and use for drivers with smaller hands and/or heavier bodies
Solution Approach 1:
The single large grip is segmented into multiple smaller grips (first grip, second grip, third grip) along the strap. This allows drivers with smaller hands to select an appropriately sized grip, while the modular segmentation maintains manageable overall complexity of the strap system.
2Reliability
If a single grip design is used, then the strap structure remains simple, but it lacks anti-slip features causing slippage when drivers attempt to use the strap
Solution Approach 1:
Anti-slip features are applied locally to the grip surfaces rather than throughout the entire strap. Each grip (first, second, and third grips) incorporates non-slip material or textured surfaces at specific contact points, providing reliable hand grip without unnecessarily complicating the overall strap structure.
3Reliability
If existing fittings are used to secure the strap to cargo vehicles, then the attachment function is achieved, but kinking occurs in the strap compromising effectiveness and longevity
Solution Approach 1:
The fitting system is designed with dynamic characteristics that allow the strap to move and adjust naturally under load. The fitting includes a swivel mechanism or articulated connection that enables the strap to orient itself toward pulling forces, preventing kinking while maintaining secure attachment to the cargo vehicle.
4Strength
If existing driver assist straps are designed, then manufacturing is simplified, but the weight barrier is insufficient posing safety risks
Solution Approach 1:
The strap incorporates composite construction with high-strength materials such as webbing made from reinforced fibers or composite polymers. This provides enhanced weight-bearing capacity and safety margins while maintaining manufacturing processes that are adapted from conventional strap production methods.
