Vehicle Partition Hook Structure That Prevents Twist and Mis-Hooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing room separation devices for motor vehicles, such as net partitions, often have a rigid upper rod that is heavy and requires significant installation space, making them cumbersome when not in use, and alternative designs with flexible hooks can be prone to incorrect orientation and malfunction.
Innovation Solution
A room separation device featuring a hook element with a connecting section formed by double rod material, which provides increased strength and prevents rotation, ensuring correct orientation and secure attachment to the vehicle's roof structure, along with a flexible wall element that can be easily stored and deployed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid upper rod is used to support the net partition, then the hooks can be correctly positioned and attached, but the device becomes heavy and requires significant installation space
Solution Approach 1:
The rigid rod is segmented into multiple individual hooks, each capable of independent attachment. This eliminates the need for a continuous rigid rod while maintaining attachment reliability at each hook position. The wall element is divided into sections with discrete hooks at regular intervals, allowing flexible configuration without requiring a heavy continuous support structure.
Solution Approach 2:
The patent replaces the rigid rod structure with flexible wall elements that have hooks attached directly to them. The wall elements can be made of flexible materials that provide sufficient support without the weight and space requirements of rigid rods. The flexible nature allows the wall to conform to different mounting configurations while maintaining structural integrity.
2Weight of stationary object
If individual hooks are used to support the net partition, then the weight and installation space are reduced, but the hooks can twist and become incorrectly oriented
Solution Approach 1:
The hooks are designed with asymmetric geometry that prevents rotation and ensures correct orientation during attachment. The hook shape includes features such as asymmetric curvature or directional elements that naturally guide the hook into the correct position and prevent it from twisting or becoming misoriented after attachment to the wall element.
Solution Approach 2:
The hooks are pre-positioned and pre-oriented on the wall elements during manufacturing, ensuring correct orientation before installation. The wall elements are supplied with hooks already attached in the correct orientation, eliminating the risk of incorrect installation by the end user and ensuring reliable attachment from the first installation.
3Ease of manufacture
If hooks are made from round wire material, then the manufacturing is simple, but the hooks can rotate freely and may not engage correctly
Solution Approach 1:
Instead of using symmetric round wire hooks that can rotate freely, the patent employs hooks with asymmetric cross-sections or directional features. The hooks may have oval, rectangular, or specially contoured cross-sections that prevent rotation and ensure correct engagement orientation while maintaining manufacturability through standard forming processes.
Solution Approach 2:
The hooks are constructed using composite material structures that combine the manufacturing simplicity of wire forming with the rotational prevention features of shaped profiles. This may involve wire hooks with molded plastic inserts, or multi-layer wire constructions that provide both ease of manufacture and reliable engagement characteristics.
