Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing sweat diverters for headwear are cumbersome, difficult to attach, and often fail to effectively prevent sweat from reaching the eyes due to imperfect integration with the hat material, leading to saturation and ineffective sweat management.

Innovation Solution

A sweat diverting textile with an integrated gutter system, comprising upper and lower gutter sections connected via posts and reinforcement scrim, seamlessly integrated into headwear fabric to divert sweat away from the eyes, even when saturated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a sweatband is worn underneath the hat to absorb sweat, then sweat absorption capacity is improved, but the device becomes cumbersome and requires frequent replacement or wringing

Engineering Contradiction:

Improvesweat absorption capacityVSAvoidconvenience of wear

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The sweat management system is divided into separate functional components: the hat provides structural coverage while the integrated gutter system handles sweat diversion. This segmentation allows each component to optimize its function without the cumulative burden of a saturated sweatband.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The gutter system acts as an intermediary structure between the sweatband and the external environment. It collects sweat from the saturated sweatband and redirects it away from the eyes, preventing the harmful effect of sweat dripping while maintaining the sweatband's absorption function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a diverter device is attached to the interior of the hat using tabs and connectors, then sweat diversion capability is improved, but attachment difficulty and inconvenience increase

Engineering Contradiction:

Improvesweat diversion effectivenessVSAvoidease of attachment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The gutter system is merged with the hat structure through integration into the interior lining fabric. This eliminates the need for separate attachment mechanisms like tabs and connectors, allowing the diverter to be installed as part of the hat's construction process without requiring user assembly.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The hat design incorporates the gutter system as a self-contained feature that requires no additional attachment steps. The integrated design allows the sweat diversion function to be automatically activated when the hat is worn, eliminating the need for user intervention in the attachment process.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If a diverter device is not integrated into the hat material, then attachment flexibility is improved, but sweat diversion effectiveness decreases due to imperfect interface

Engineering Contradiction:

Improveattachment flexibilityVSAvoidsweat diversion effectiveness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The gutter system is constructed from materials and integrated in a manner that is homogeneous with the hat's interior lining. This ensures a seamless interface that prevents sweat leakage at the boundaries between the diverter and the hat material, maintaining diversion effectiveness.

Inventive Principle:

Principle #33Homogeneity

4Quantity of substance

If conventional sweatbands are used, then initial sweat absorption is improved, but effectiveness is lost after saturation

Engineering Contradiction:

Improvesweat absorption capacityVSAvoidduration of effectiveness

Core Design Contradiction:

Quantity of substanceVSDuration of action of stationary object

Solution Approach 1:

The gutter system provides continuous sweat diversion functionality that does not depend on the saturation state of the sweatband. While the sweatband continues to absorb sweat, the gutter simultaneously redirects excess sweat away from the eyes, maintaining effective sweat management throughout the wearing period without requiring removal or replacement.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A sweat diverting gutter integrated into headwear for removing perspiration that escapes the material including a substantially u-shaped gutter formed from upper and lower gutter portions connected by at least one connecting post and a corresponding post receptacle between the gutter parts. The placement of the diverting gutter on the exterior side of the headwear causes excess sweat to be laterally moved from on or around the wearer's forehead away from the eyes and face.
