Headrest Item Holder with Closed-Loop Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for securing items in vehicles, such as purses, are inadequate as they often slide, tip over, or cause damage due to compressive forces, and safety concerns arise from hooks that can impale passengers. Current methods fail to accommodate a wide range of objects and do not effectively minimize movement during vehicle motion.
Innovation Solution
An item-holding device attachable to a car seat headrest, featuring a flexible attachment member and a double hook-shaped holding member with adjustable height and tension, which securely holds items of various shapes and sizes by wrapping around the headrest and providing a stable, adjustable mechanism to prevent swinging and impalement risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If open-ended hooks are used to hang items from the headrest, then items can be suspended above the floor, but the hooks may impale passengers or poke them in the eye during abrupt stops
Solution Approach 1:
Instead of using open-ended hooks that point downward and can impale passengers, the patent uses closed-loop hooks that encircle the headrest pole. This inverts the traditional hook design from an open endpoint to a closed circle, eliminating the sharp protruding end that causes injury while maintaining the suspending function.
Solution Approach 2:
The patent converts the potential harm of hook sharpness into a benefit by using the closed-loop design where the entire perimeter of the hook serves as the contact point with the headrest, distributing force evenly and eliminating concentrated stress points that could cause injury during sudden stops.
2Device complexity
If a single hook is used to hang an item, then the apparatus is simple, but the item can swing back and forth during vehicle motion
Solution Approach 1:
The patent merges two hook functions into a single dual-hook assembly where both hooks are attached to the same headrest pole and work together to suspend the item. This combination creates a stable triangular support structure with the item, preventing swinging motion while maintaining overall device simplicity.
Solution Approach 2:
The patent transitions from a single-point suspension to a multi-point suspension system by using two hooks positioned at different locations on the headrest pole. This adds spatial distribution in the vertical dimension, creating a more stable suspension geometry that resists swinging during vehicle motion.
3Adaptability or versatility
If fixed-height hooks are used, then the apparatus structure is simple, but it cannot accommodate items of different sizes
Solution Approach 1:
The patent implements a dynamic height adjustment system where the hooks can be repositioned vertically along the headrest pole. This transforms the fixed static structure into a flexible dynamic system that can adapt to different item sizes by adjusting the hook positions, while using simple mechanical features like slots or notches to enable adjustment without complex mechanisms.
