Solution Overview

Problem

Existing wetsuits face challenges in providing a durable, comfortable, and easily accessible relief opening that maintains a watertight seal during marine sports, making it difficult to urinate while maintaining thermal insulation and flexibility.

Innovation Solution

A foldable, elastic funnel made from watertight material is integrated into the wetsuit, secured by a covering flap, allowing for easy access and closure to prevent water ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a relief opening is provided on the crotch area of a wetsuit, then ease of operation for urination is improved, but watertightness and thermal insulation are worsened

Engineering Contradiction:
Improveease of urinationVSAvoidwatertight seal
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The relief opening uses a dynamic flap mechanism that can transition between closed (watertight) and open (accessible) states. The flap is secured to the wetsuit interior and can be manually opened during urination, then closed to restore the watertight seal. This dynamic element allows the system to adapt between two functional states, resolving the contradiction between needing access for urination and maintaining thermal insulation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The relief opening incorporates a flexible flap made of elastic material that conforms to the wetsuit interior. This thin film structure provides a watertight barrier when closed while remaining flexible enough to allow easy opening and closing. The elastic properties enable the flap to return to its closed position after being opened, automatically restoring the thermal insulation without requiring complex mechanical components.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If a relief opening is provided on the crotch area of a wetsuit, then ease of operation for urination is improved, but structural durability is worsened

Engineering Contradiction:
Improveease of urinationVSAvoiddurability of relief opening
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The relief opening employs a dynamic flap mechanism rather than a permanent fixed opening. The flap can be opened only when needed and closed afterward, minimizing the time the structural integrity is compromised. This temporary, controlled access approach maintains overall structural durability while providing necessary functionality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The flap is constructed from elastic material that integrates with the wetsuit fabric, distributing stress across a larger area rather than creating a weak point. The flexible nature of the material allows it to stretch and flex with the wetsuit during movement, preventing tearing or detachment that would occur with rigid components in this high-stress area.

Inventive Principle:
Principle #30Flexible shells and thin films

3Reliability

If the wetsuit is made substantially watertight, then thermal insulation is improved, but ease of operation for relief is worsened

Engineering Contradiction:
Improvewatertight sealVSAvoidaccessibility of relief opening
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The flap mechanism provides a simple dynamic interface that requires minimal effort to operate. The elastic material and securement design allow the flap to be opened with one hand during sporting activities, maintaining ease of operation despite the overall watertight construction. The simplicity of the mechanism ensures it can be operated quickly without compromising the watertight seal when closed.

Inventive Principle:
Principle #15Dynamics
