Jacket Pocket Arrangement With Movable Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cold weather apparel becomes bulkier and less comfortable to maintain warmth, necessitating a solution that enhances insulation without adding bulk or weight.
Innovation Solution
A jacket design featuring interconnected pocket cavities with a movable pocket insert that allows for shared insulation between hands, reducing air leakage and enhancing warmth through a zipper and sealing member configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional cold weather apparel uses thicker insulation to maintain warmth, then warmth is improved, but bulk and weight increase
Solution Approach 1:
The patent divides the insulation system into separate modular components - a liner with insulation that can be detached and stored. This allows the insulation to be segmented from the main jacket body, providing warmth when needed while eliminating bulk and weight when the liner is removed or stored in a pocket.
Solution Approach 2:
The jacket incorporates a dynamic insulation system where the liner can be inserted or removed based on environmental conditions. The pocket member with mating insert provides a dynamic storage mechanism that allows the liner to be concealed within the jacket body when not in use, transforming the static jacket into a dynamically adaptable system.
2Temperature
If conventional cold weather apparel uses thicker insulation to maintain warmth, then warmth is improved, but bulk increases
Solution Approach 1:
The liner is designed to nest within the jacket body when not in use. The pocket member with its mating insert creates a nested configuration where the insulated liner can be stored inside the jacket's own structure, eliminating external bulk while preserving the insulation capability when needed.
3Ease of operation
If separate pocket cavities are used for each hand, then accessibility is improved, but insulation efficiency decreases due to air leakage
Solution Approach 1:
The patent merges the two separate pocket cavities into a single shared insulated space when the liner is inserted. The first and second pocket members with their mating inserts create a unified continuous insulation barrier, eliminating air leakage paths between separate pockets while still allowing independent access to each pocket opening.
4Loss of energy
If a shared pocket cavity is used for both hands, then insulation efficiency is improved, but accessibility and independence decrease
Solution Approach 1:
While the insulation is shared, the pocket system is segmented into two independently accessible openings. Each hand can access its own pocket cavity through separate openings in the liner, maintaining operational independence while benefiting from the continuous insulation barrier that prevents air leakage.

AI summary
A jacket includes a body portion having an exterior surface and a first edge for mating with an opposing second edge. A first pocket opening extends through the exterior surface of the body portion. A first pocket member at least partially defines a first pocket cavity in communication with the first pocket opening and the first pocket member at least partially defines a pocket mating opening. A second pocket opening extends through the exterior surface of the body portion and a second pocket member at least partially defines a second pocket cavity in communication with the second pocket opening. The second pocket member at least partially defines a pocket mating insert that is moveable between a retracted position spaced inward from the first edge and an extended position extending outward from the second edge. The pocket mating insert is configured to be received by the pocket mating opening.
