Anti-odor Apparel with Elastic Lifting Sleeve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-odor solutions for underarm regions, such as antiperspirants, armpit patches, and functional fabric cut pieces, face issues like skin allergies, user discomfort, visibility, and high costs due to the need for specialized materials and manufacturing, which are not effectively addressed by commercially available full-piece antibacterial clothing.
Innovation Solution
An anti-odor apparel design featuring an extended sleeve made from functional fabric with anti-odor properties, stitched to form a loop-shaped connection around the underarm area, and a lifting unit using elastic strings or members to ensure the fabric covers and contacts the underarm area effectively, providing antibacterial and deodorizing functions without additional stitches or visible cut pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full-piece antibacterial and deodorant clothing is used, then underarm odor elimination is improved, but manufacturing cost increases significantly
Solution Approach 1:
The invention divides the apparel into two parts: a standard upper body garment and a separate extended sleeve component. Only the extended sleeve portion that contacts the underarm area is made from expensive functional fabric with antibacterial and deodorant properties, while the rest of the garment uses conventional materials. This segmentation allows the functional fabric to be applied locally where needed, reducing overall manufacturing cost while maintaining odor elimination effectiveness.
Solution Approach 2:
The invention applies functional fabric with special antibacterial and deodorant properties only to the extended sleeve portion that directly contacts the underarm area, rather than using it throughout the entire garment. This local quality approach ensures that the expensive functional materials are concentrated where they are most needed for odor elimination, optimizing both performance and cost-effectiveness.
2Reliability
If additional functional fabric cut pieces are sewn to armpit parts, then odor elimination is improved, but appearance is compromised due to visible stitches and cut pieces
Solution Approach 1:
The invention merges the extended sleeve with the main upper body garment through stitching, creating a unified appearance. The extended sleeve is designed to extend from the existing sleeve and wrap around the underarm area, forming a continuous fabric surface without visible cut pieces or separate attachments. This merging approach maintains a natural, seamless appearance while providing effective odor elimination through the functional fabric.
3Reliability
If armpit patches are used, then odor elimination is improved, but user comfort deteriorates due to sticky and wet patches
Solution Approach 1:
The invention uses functional fabric with inherent antibacterial and deodorant properties that can be washed and reused multiple times, replacing the need for disposable armpit patches. The functional fabric is integrated into the washable extended sleeve, providing long-term odor elimination without the discomfort of sticky, disposable patches that need frequent replacement.
4Reliability
If antiperspirant and deodorant are applied directly to underarm, then odor elimination is improved, but health risks increase due to skin allergies and potential cancer risk
Solution Approach 1:
The invention extracts the deodorant function from direct skin application and transfers it to a fabric-based system. The functional fabric with antibacterial and deodorant properties is incorporated into the extended sleeve, eliminating the need for direct application of chemical antiperspirants and deodorants to the skin. This extraction approach reduces exposure to potentially harmful chemicals while maintaining odor elimination effectiveness through the fabric barrier.
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 provides effective antibacterial and deodorizing performance for underarm areas without the drawbacks of existing solutions, maintaining a natural appearance and allowing for adjustable tension, concealment, and washability, while using less fabric and being cost-effective.
Implementation Method 1
a lifting unit including an elastic string that has two opposite connecting end portions and that is positioned at and that extends along the loop-shaped sewing connection. The connecting end portions of the elastic string are held to the loop-shaped sewing connection at two different lifting points of the loop-shaped sewing connection, respectively, such that the elastic string is held under tension so as to generate a lifting force that acts on the extended sleeve to elastically lift at least one of the lower end portions of the sleeve segment and the extension segment toward the underarm area

AI summary
An anti-odor apparel includes: an upper body clothing that defines an open end; an extended sleeve stitched to the open end to form a loop-shaped sewing connection, the extended sleeve having a sleeve segment and an extension segment which respectively have lower end portions that are made from a functional fabric; and a lifting unit including an elastic string that has two connecting end portions and that extends along the loop-shaped sewing connection. The connecting end portions of the elastic string are held to the loop-shaped sewing connection such that the elastic string is held under tension so as to elastically lift at least one of the lower end portions of the sleeve segment and the extension segment toward the user's underarm area.
