Enlarged-Head Belt Hook for Secure Floor Panel Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt hooks fail to securely anchor in floor panel openings under high tension forces without causing the floor panels to tear or deform, leading to potential loss of the hook from the opening.
Innovation Solution
A belt hook with an enlarged head, featuring a U-shaped hook with one leg widened to form a hammer head, which complements the oval openings of the floor panel, providing increased stability and secure anchoring by immersing itself at the longest point of the oval and lying captively against the edge areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional belt hook is used to anchor in floor panel openings, then the hook can be inserted into the opening, but under high tension forces the floor panel tears or deforms and the hook becomes dislodged
Solution Approach 1:
The belt hook is divided into distinct functional segments: a U-shaped hook portion with two legs, a connecting piece, and an enlarged head portion. This segmentation allows each part to perform its specific function - the hook legs engage with the opening edges while the enlarged head distributes tension forces, preventing both hook dislodgement and panel deformation
Solution Approach 2:
The belt hook transitions from a simple planar hook shape to a three-dimensional structure with an enlarged head that extends perpendicular to the hook plane. This dimensional addition creates a bearing surface that distributes loads across multiple points on the floor panel, preventing localized stress concentration that would cause tearing or deformation
2Reliability
If a conventional belt hook without enlarged head is used, then the device complexity is low, but the contact surface area with the floor panel is insufficient leading to hook dislodgement under tension
Solution Approach 1:
The enlarged head is positioned specifically at the critical location where the hook engages with the floor panel opening. This localized enlargement provides the necessary contact surface area and load distribution only where needed, without adding complexity to the entire hook structure. The rest of the hook maintains a simple U-shaped design for easy insertion

AI summary
The invention relates to a strap hook with an enlarged head for hooking into a base plate with openings, in particular into base plates with a plurality of openings. The strap hook, together with the base plate, forms a fastening arrangement and is in particular part of a tensioning strap, which is, for example, placed around a car tire for lashing or threaded around the spokes of car rims.
