Segmented Jacket with Free-Floating Sleeves for Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jackets and coats with water-repellent or wind-repellent materials often lack sufficient stretchability and breathability, restricting movement during physical activities, and may not provide adequate noise reduction.
Innovation Solution
A jacket/coat design featuring a layered construction with a partial shrug-like portion made from elastic material and a vest portion, where the sleeves are free-floating to eliminate shoulder seams, allowing for enhanced range of motion and ventilation, and optionally incorporating perforations for water drainage and a composite sleeve for improved breathability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water-repellent or wind-repellent materials are used in jackets, then protection from environmental elements is improved, but stretchability and breathability are reduced
Solution Approach 1:
The jacket is divided into multiple functional layers: an inner layer with water-repellent material for protection, and an outer layer with elastic material for stretchability. This segmentation allows each layer to perform its specific function without compromising the other, resolving the contradiction between protection and flexibility.
Solution Approach 2:
The jacket uses composite construction combining different materials with complementary properties - water-repellent fabric for environmental protection and elastic fabric for stretchability. The layered composite structure integrates the benefits of both material types, achieving both protection and flexibility simultaneously.
2Object-affected harmful factors
If conventional jacket materials are used, then environmental protection is improved, but range of motion during physical activity is restricted
Solution Approach 1:
The jacket structure is segmented into protective and flexible zones. The body portion uses water-repellent material for protection, while the sleeve portions use elastic material to accommodate arm movement. This segmentation enables the jacket to provide environmental protection where needed while allowing full range of motion in active areas.
Solution Approach 2:
Different regions of the jacket have different material properties tailored to their functional requirements. The sleeves and shoulder areas use highly elastic materials to accommodate arm movement, while the torso uses water-repellent material for protection. This local differentiation of material quality resolves the contradiction between protection and adaptability.
3Adaptability or versatility
If stretchable materials are used in jackets, then range of motion is improved, but noise during movement increases
Solution Approach 1:
Stretchable elastic material is applied locally only in the sleeve portions where movement is required, rather than throughout the entire jacket. This localized application provides the necessary range of motion while minimizing the surface area that could generate noise during movement.
Solution Approach 2:
The jacket is segmented so that noise-sensitive areas (torso) use quieter water-repellent materials, while movement-required areas (sleeves) use stretchable materials. This segmentation isolates the noise-generating potential to minimal areas while maintaining overall functionality.
4Ease of operation
If a loose fit jacket design is used, then comfort is improved, but protection from environmental elements is reduced
Solution Approach 1:
The jacket uses a segmented layered design where the inner layer provides a comfortable loose fit against the body, and the outer layer provides environmental protection. This segmentation allows the comfort function and protection function to be decoupled and optimized independently.
Solution Approach 2:
The layered composite construction combines a comfortable inner layer with a protective outer layer. The composite structure integrates the comfort benefits of loose fit with the protection benefits of water-repellent materials, achieving both comfort and environmental protection simultaneously.

AI summary
The present invention relates to a jacket/coat designed to provide an enhanced range of motion. This is accomplished by having a layered construction comprising different fabric/textile materials where the enhanced range of motion is desired. The jacket/coat in accordance with the present invention particularly provides an enhanced range of motion for a wearer around the shoulders and arms. This enhanced range of motion may be especially beneficial when the wearer is engaged in a physically demanding activity or any activity benefitting from a wide range of movement by the wearer's arms and shoulders.
