Headrest Sliding Hook for Secure Item Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles and other seating environments, items placed on seats can slide off during maneuvers, leading to potential damage or spillage, as there is no secure place to store them while allowing for easy access.
Innovation Solution
A headrest assembly with a sliding hook mechanism that can be moved between positions to stow or deploy, providing a secure surface for items without obstructing the seat's use, featuring a bracket with tongues and grooves for sliding engagement and protrusions/recesses for detent-type positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a headrest assembly with a sliding hook mechanism is added to provide secure item storage, then item security during vehicle movements is improved, but device complexity increases
Solution Approach 1:
The hook mechanism is nested within the headrest assembly, with the hook portions integrated into the headrest structure. The bracket with channel is attached to the headrest, and the hook slides within this bracket. This nesting approach allows the hook mechanism to be compact and integrated into the existing headrest space, providing secure item storage without significantly increasing overall device complexity.
Solution Approach 2:
The hook is designed to be slidable between multiple positions (first, second, and third positions) along the channel of the bracket. This dynamic capability allows the hook to be adjusted to different locations, enabling it to secure items at various points on the headrest while maintaining a relatively simple mechanical structure based on sliding engagement with detent-type positioning.
2Stability of the object's composition
If a hook mechanism is integrated into the headrest to secure items, then item stability is improved, but the seat's usability is worsened due to potential obstruction
Solution Approach 1:
The hook can slide between multiple positions along the channel, allowing it to be moved out of the way when not in use or when item storage is not needed. This dynamic positioning capability maintains item stability when the hook is deployed while preserving seat usability when the hook is repositioned or stowed, reducing obstruction to seat access.
3Adaptability or versatility
If a sliding hook mechanism with multiple positions is implemented, then adaptability is improved, but manufacturing precision requirements are worsened
Solution Approach 1:
The hook slides along a channel with detent-type positioning features (protrusions and recesses) that provide stable positioning at discrete locations. This approach achieves adaptability through multiple positions while using simple mechanical detents rather than complex precision mechanisms, balancing manufacturing precision requirements with versatile functionality.

AI summary
A headrest assembly may include a headrest having a first external surface and a second external surface and a hook slidingly engaged within the headrest. The hook may include a first hook portion and a second hook portion. When the hook is in a first position, the first hook portion is substantially flush with the first external surface and the second hook portion is substantially flush with the second external surface. When the hook is in a second position, the first hook portion is offset from the forward external surface and the second hook portion is offset from the rearward external surface.
