Combat Shirt Torso and Collar Fabric Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ballistic protective apparel, especially undergarments, face challenges in providing both protective and wicking abilities while maintaining shape and preventing heat buildup during high metabolic activities, as the heavy and less breathable durable fabric beneath the armor can lead to shape distortion and discomfort.
Innovation Solution
A combat shirt with a wicking, lightweight torso element and durable collar and sleeves, where the collar connects the sleeves to prevent distortion and the torso element is overlain by the armored vest, using different fabrics for varying functions and properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a durable fabric is worn beneath the armor, then the wearer maintains uniform standards and protects from sun and dust, but heat build-up increases and breathability decreases
Solution Approach 1:
The combat shirt uses different fabrics for different body regions: a breathable wicking fabric for the torso area covered by armor, and a durable fabric for the sleeves and collar areas not covered by armor. This local differentiation allows each region to perform its specific function optimally.
Solution Approach 2:
The shirt is segmented into distinct functional zones with different material properties. The torso portion uses lightweight wicking material for moisture management, while the sleeves and collar use durable material for protection and shape retention, creating a multi-functional garment.
2Temperature
If a wicking lightweight fabric is used in the torso, then heat dispersion and moisture evaporation improve, but the shirt loses its shape and the sleeves pull down the resilient torso material
Solution Approach 1:
The collar is constructed from durable, low-stretch fabric that provides structural support and maintains the shirt's shape, while the torso remains made of elastic wicking material for comfort and moisture management. The durable collar locally compensates for the overall shapelessness caused by the elastic torso fabric.
Solution Approach 2:
The shirt combines two different fabric types with complementary properties: an elastic wicking fabric for the torso that manages moisture and heat, and a durable low-stretch fabric for the collar and sleeves that maintains shape and provides protection. This composite construction resolves the shape retention issue.
3Strength
If the collar and sleeves are formed of more durable material, then protection and shape retention improve, but the overall garment weight and complexity increase
Solution Approach 1:
Durability is applied locally only where needed (collar and sleeves exposed to environmental elements and friction) rather than throughout the entire garment. The torso portion remains lightweight for comfort and moisture management, minimizing overall weight while providing protection where required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively balances protective and wicking abilities while maintaining the shirt's shape, enhancing comfort and heat dispersion by using more durable materials for the collar and sleeves and a stretchy material for the torso, ensuring the garment remains secure and comfortable under armored regions.

AI summary
A protective body armor system for protection against ballistic threats has an armored element such as a vest with front and rear ballistic armor. A long-sleeved shirt is worn beneath the ballistic armor which has a wicking, lightweight, low thermal insulation torso element. Two long sleeves are connected to and extend from the torso element. The torso element is substantially overlain by portions of the armor element, while portions of the sleeve extend beyond the armored element. The shirt has a durable collar connected to the torso element and to the two sleeves. The collar extends upwardly from the armored element. The collar is less resilient than the torso element, and serves to connect the two sleeves and to restrain the garment from undesired distortion.
