Elongate Strap Headrest Mount for Vehicle Trash Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for containing trash in vehicles are either cumbersome, intrusive, or pose safety risks, particularly when trying to position a trash receptacle between front seats, and often fail to securely hold plastic grocery bags in place during vehicle motion.
Innovation Solution
An elongate strap with specially-shaped headrest post and bag handle portions that securely encircles both headrest posts, drapes over the seat shoulder, and features forward-projecting hooks to hold bag handles apart, ensuring easy disposal and resistance to motion-induced displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid trash can is placed on the floor or center console, then it provides stable trash containment, but it intrudes into passenger leg room and may be knocked over
Solution Approach 1:
The invention transitions the trash can from floor-level placement (2D horizontal space) to suspension from the headrest (utilizing vertical space and the third dimension). This allows the trash can to be positioned above the passenger compartment without occupying leg room, resolving the contradiction between stability and accessibility.
Solution Approach 2:
The invention introduces a headrest-mounted bracket as an intermediary structure between the headrest and the trash can. This mediator provides a secure attachment point that stabilizes the trash can while keeping it out of the way of passenger legs, simultaneously achieving both reliability and ease of operation.
2Ease of manufacture
If a flexible strap is used to suspend a plastic grocery bag, then it is cost-effective and simple, but the bag handle slips off during vehicle motion
Solution Approach 1:
The invention segments the attachment system into two distinct components: a rigid headrest-mounted bracket for secure anchoring and a flexible plastic grocery bag for trash containment. The bracket portion provides reliable handle retention through its rigid structure and secure mounting, while the bag portion maintains cost-effectiveness and simplicity by using an existing flexible plastic bag.
Solution Approach 2:
The invention introduces a rigid bracket as an intermediary between the headrest and the flexible plastic bag. This mediator translates the secure attachment capability of the rigid bracket to the flexible bag, preventing the bag handle from slipping off during vehicle motion while maintaining the cost-effectiveness of using a plastic grocery bag.
3Ease of operation
If hooks are used to hold bag handles, then it enables easy trash disposal, but the bag may swing during vehicle motion
Solution Approach 1:
The invention positions the trash can adjacent to the driver's door, creating a counterbalancing effect that reduces swinging during vehicle motion. This placement allows the trash can to act as a counterweight that stabilizes the bag position, preventing excessive swinging while maintaining easy accessibility for the driver to dispose of trash.

AI summary
A shaped elongate strap enables a plastic grocery bag to be used for trash disposal in a vehicle. It has a shaped headrest post gripping top portion at one end and a shaped grocery bag handle gripping portion at the other. The top portion encircles both headrest posts, allowing the strap to drape over the shoulder of the seat so that the bag gripping portion hangs between the seats. The bag gripping portion comprises two spaced-apart hook parts for the bag handles.
