Back-Opening Jacket With Detachable Flaps for Seated Child Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jackets that open from the front pose difficulties in removing and putting on a child in a seated position, such as in a car seat, due to the jacket being wedged between the child's back and the seat, requiring manual effort and time, especially since arms do not naturally bend backward.
Innovation Solution
A jacket design featuring a first and second back flap that are detachably connectable via connectors on the upper ends, allowing the back side to open and close, enabling easy removal and reattachment by pulling the jacket forward, similar to a conventional front opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the jacket opens from the front like conventional jackets, then the jacket structure is simple and familiar, but it becomes difficult to remove and put on when the child is in a seated position because the jacket is wedged between the child's back and the seat back
Solution Approach 1:
The jacket opening is inverted from the conventional front opening to a back opening. The first back flap and second back flap are positioned on the back side of the jacket, allowing the opening to be located at the rear rather than the front. This inversion enables easy removal and attachment when the child is seated, as the opening can access the child's back without being blocked by the seat back.
Solution Approach 2:
The opening mechanism transitions from a single-plane front opening to a multi-component back opening system. The first back flap and second back flap create a distributed opening structure on the back side, allowing the opening to function across different spatial dimensions and orientations, improving accessibility when the child is seated.
2Productivity
If the jacket is pulled off one arm at a time due to arms not bending backward naturally, then the jacket structure remains simple, but the process becomes time-consuming and effortful
Solution Approach 1:
The opening direction is inverted from front-to-back to back-to-front during removal. By positioning the opening on the back side, the jacket can be pulled off in a natural forward motion rather than requiring backward arm bending, significantly reducing the time and effort needed for removal and attachment.
3Reliability
If the jacket needs to be put back on prior to exiting the vehicle, then the child remains protected, but the repeated manual process increases frustration and time loss
Solution Approach 1:
The back opening design allows the jacket to be quickly put on and taken off by simply pulling the flaps apart or together along the back opening. This inverted opening mechanism eliminates the frustration of repeated manual fastening and unfastening, making the process quick and easy while maintaining continuous child protection.

AI summary
A jacket includes a first back flap, a main body including a front portion and second back flap, and a pair of sleeves. The first back flap and the second back flap are detachably connectable to one another to selectively open and close an opening on the back side of the jacket. The first back flap may include a first connector disposed on an upper end of the first back flap and the second back flap may include a second connector disposed on an upper end of the second back flap, the first connector and the second connector being detachably connectable to one another to facilitate the opening and closing of the opening in the jacket. The jacket may also include a hood detachably connectable to a collar on the first back flap.
