Multi-Layer Undergarment Sweat-Curtailing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sweat marks and associated body odor in undergarments are considered unprofessional and can negatively impact performance, as existing undergarments fail to effectively conceal sweat and prevent odor formation, especially in stress or exertion situations.
Innovation Solution
The development of undergarments with a multi-layer sweat-curtailing design featuring a waterproof middle layer and antibacterial materials, minimizing seams in sweat-prone areas and incorporating stretchy, breathable fabrics like micro modal or bamboo with spandex for comfort and sweat absorption, along with an elongated waist for additional coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing undergarments are used, then basic comfort is provided, but they fail to effectively conceal sweat and prevent odor formation
Solution Approach 1:
The undergarment is divided into multiple functional layers: an outer layer with moisture-wicking properties, a middle waterproof layer to block sweat transmission, and an inner antibacterial layer to prevent odor. This segmentation allows each layer to address specific aspects of the sweat and odor problem independently.
Solution Approach 2:
The undergarment combines different materials with complementary properties: stretchy breathable fabrics (micro modal or bamboo) for comfort and moisture absorption, waterproof materials for sweat blocking, and antibacterial materials for odor prevention. This composite structure resolves the contradiction by integrating multiple functions into a single garment.
2Reliability
If waterproof materials are added to block sweat, then sweat visibility is reduced, but breathability and comfort may be compromised
Solution Approach 1:
The waterproof material is strategically placed only in the crotch and groin areas where sweat transmission is most problematic, rather than throughout the entire garment. This localized application maintains sweat blocking effectiveness while preserving breathability and comfort in other areas.
Solution Approach 2:
The garment combines waterproof materials with stretchy breathable fabrics and moisture-wicking materials in a multi-layer construction. This composite approach allows the waterproof layer to block sweat while the other layers maintain breathability and comfort.
3Object-generated harmful factors
If antibacterial materials are incorporated to prevent odor, then odor control is improved, but device complexity increases
Solution Approach 1:
The antibacterial, moisture-wicking, and waterproof functions are merged into a single integrated multi-layer garment structure. This consolidation achieves comprehensive odor and sweat control without requiring multiple separate garments or complex additional components.
Solution Approach 2:
Antibacterial materials are incorporated as one layer within the composite multi-layer structure, combining odor prevention with sweat blocking and moisture-wicking functions in a unified garment design.
