Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional sweat absorbers in headwear, especially free-sized ones, fail to provide adequate elasticity, comfort, and functionality, often causing compression impressions and sweat leakage due to single elastic bands or weakened elasticity when using cover portions, which limits their effectiveness in absorbing sweat and maintaining temperature control.

Innovation Solution

A multi-functional sweat absorber design featuring a first sweat absorber with polypropylene yarns for elasticity and a second sweat absorber with different materials and textures, providing detachable Velcro fastening, which enhances stretchability, comfort, and aesthetic appeal while maintaining antibacterial and deodorization functions, and temperature control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the sweat absorber is formed of an only elastic band to improve elasticity and allow various expressions, then elasticity is improved, but impressions remain on the forehead and compression sensations occur reducing wearing comfort

Engineering Contradiction:

ImproveelasticityVSAvoidwearing comfort

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The sweat absorber is divided into two separate components: a first sweat absorber (elastic band) and a second sweat absorber (cover portion). This segmentation allows each component to fulfill its specific function - the elastic band provides elasticity while the cover portion prevents impressions and compression sensations on the forehead.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first sweat absorber (elastic band) is placed inside the second sweat absorber (cover portion). The elastic band is inserted into the cover portion and secured, creating a nested structure where the inner elastic component provides stretchability while the outer cover component provides comfort and prevents direct contact issues.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If a cover portion surrounds the elastic band to reduce impression and compression problems, then wearing comfort is improved, but elasticity is weakened reducing adaptability to various head sizes

Engineering Contradiction:

Improvewearing comfortVSAvoidelasticity

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The elastic band is nested inside the cover portion, allowing the elastic component to maintain its elasticity while being protected and comfort-enhanced by the outer cover. The nested structure enables both components to function simultaneously without compromising each other's properties.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Shape

If characters or logos are woven on the cover portion, then aesthetic appeal is improved, but workability deteriorates and loss occurs due to cutting

Engineering Contradiction:

Improveaesthetic appealVSAvoidworkability

Core Design Contradiction:

ShapeVSEase of manufacture

Solution Approach 1:

Instead of weaving characters or logos on the cover portion (which requires complex weaving and causes cutting loss), the invention inverts the approach by weaving the characters or logos directly on the elastic band. This reversal simplifies manufacturing, eliminates cutting loss, and maintains aesthetic appeal.

Inventive Principle:

Principle #13The other way round (Inversion)
