Concealed Stretch Back Layer for Outerwear Garment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional outerwear garments restrict arm, torso, and shoulder motion due to single-piece construction, long sleeves, full-length zippers, and bulkiness, making them less suitable for active environments while maintaining integrity and function.
Innovation Solution
An outerwear garment with a concealed stretch back layer comprising an outer shell layer, an exterior layer action back, and an arm sleeve panel, where the action back lining includes a stretch panel and shell panel integrated into the back portion, enhancing flexibility without compromising the garment's integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-piece construction is used for the outer shell, then the garment structure is simple and integrity is maintained, but the range of motion for arms, torso, and shoulders is restricted
Solution Approach 1:
The outer shell is divided into multiple panels including front panels, back panels, and sleeve panels that are selectively connected through zippered openings. This segmentation allows independent movement of garment sections, enabling greater range of motion for arms and torso while maintaining overall structural integrity when zipped closed.
Solution Approach 2:
The garment incorporates dynamic connectivity where panels can be connected or disconnected based on movement requirements. The zippered openings allow the garment to transition between a closed integrated state for protection and an open segmented state for enhanced mobility during active movements.
2Object-affected harmful factors
If long sleeves and full-length zippers are used, then coverage and protection are improved, but binding and restriction of arm and shoulder motion increases
Solution Approach 1:
The long sleeves are constructed with segmented panels connected by zippered openings, allowing the sleeve to be divided into sections that can move independently. This maintains full-length coverage for protection while enabling the sleeve to accommodate arm bending and shoulder movement without binding.
Solution Approach 2:
The garment uses adjustable zipper configurations that can be opened to varying degrees depending on movement requirements. When full protection is needed, zippers remain closed; when arm or shoulder movement is required, selective zipper sections can be opened to reduce restriction while maintaining coverage in other areas.
3Object-affected harmful factors
If bulky materials are added for cold weather protection, then warmth and skin protection are improved, but the garment becomes more restrictive and less suitable for active environments
Solution Approach 1:
Insulating layers are divided into separate panels that can be independently adjusted or removed. This allows the warmth-providing materials to be distributed strategically in areas needing protection while leaving movement areas less restricted, maintaining both thermal protection and range of motion for active environments.

AI summary
An outerwear garment with a concealed stretch back layer disclosed that improves a wearer's range of motion, while maintaining the integrity and function of the outerwear garment. The outerwear garment comprises an outer shell layer, an exterior layer action back, arm sleeve panel and an action back lining. The exterior layer action back is integrated into the back portion of the outer shell layer. The arm sleeve panel is attached to the outer shell layer at least at the front portion and the back portion of the outer shell layer. The action back lining comprises a concealed stretch back layer that is discrete from the outer shell layer and positioned in the back portion of the outer shell layer. The concealed stretch back layer comprises a stretch panel and a shell panel joined together and to the outer shell layer.
