Solution Overview

Problem

Existing footwear designs for sailing lack adequate support and traction, particularly on wet surfaces, and fail to effectively prevent water ingress and pressure points, leading to instability and slipping during sailing maneuvers.

Innovation Solution

A sailing shoe with a water-durable upper, a slip-resistant sole featuring a herringbone pattern, and a substantially rigid support member extending from the toe to the front ankle, combined with an upper cover that prevents the support member from contacting the foot, providing additional protection and traction through a wrap-around sole and strategically placed gripping members.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing footwear designs for sailing are used, then the footwear provides basic water durability, but they lack adequate support and traction on wet surfaces, leading to instability and slipping

Engineering Contradiction:
Improvestability and traction on wet surfacesVSAvoidfootwear structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The footwear is divided into distinct functional segments: a water-durable upper material for water resistance, a slip-resistant sole with herringbone pattern for traction, and a substantially rigid support member for structural stability. Each segment addresses specific performance requirements independently, resolving the contradiction between reliability and complexity by modularizing the design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The footwear combines multiple materials with complementary properties: water-durable upper material for water resistance, rigid support member for structural integrity, and slip-resistant sole material for traction. This composite approach achieves superior stability and traction on wet surfaces without requiring overly complex structural designs.

Inventive Principle:
Principle #40Composite materials

2Reliability

If existing footwear designs are used, then the footwear allows flexibility and comfort, but they fail to effectively prevent water ingress and pressure points

Engineering Contradiction:
Improvewater ingress preventionVSAvoidfoot comfort and flexibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The footwear applies different material properties to different regions: the upper uses water-durable material specifically for water ingress prevention, while the support member provides rigid support in areas requiring pressure distribution. This localized application of material qualities maintains comfort and flexibility in non-critical areas while providing enhanced protection where needed.

Inventive Principle:
Principle #3Local quality

3Strength

If existing footwear designs are used, then the footwear provides basic protection, but they lack adequate support members, leading to pressure points and reduced stability

Engineering Contradiction:
Improvestructural support and pressure distributionVSAvoidsupport structure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The invention extracts and emphasizes the support member as a distinct, essential component separate from the upper and sole. This substantially rigid support member is specifically designed to provide structural support and distribute pressure, resolving the contradiction by isolating the support function into a dedicated element rather than relying on complex integration of multiple components.

Inventive Principle:
Principle #2Taking out (Extraction)
