Solution Overview

Problem

Existing shoe uppers for sports shoes lack both stability and comfort, often fitting either too tightly and uncomfortably or loosely, leading to poor control during movements and rapid changes in direction.

Innovation Solution

A shoe upper design where at least 50% of the surface is covered by a tape portion comprising connected tapes, which provide stability and flexibility by distributing external forces evenly and allowing for stretching, while being lightweight and comfortable, with the tapes connected along their parallel edges through stitching, gluing, or welding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the upper is made with traditional materials and construction, then it provides enclosure and basic stability, but it is either too tight and uncomfortable or too loose and provides poor control

Engineering Contradiction:
Improvewearing comfortVSAvoidfoot control stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The upper is divided into multiple independent tape elements (first tape element, second tape element, third tape element, fourth tape element) that can move independently relative to each other. This segmentation allows each tape to adapt to foot movements separately, providing both comfort through flexibility and stability through coordinated support across multiple segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The tape elements are designed to be dynamically movable relative to one another, allowing the upper structure to adapt in real-time to foot movements during sports activities. This dynamic configuration enables the upper to transition between providing a snug fit for control and allowing natural foot expansion for comfort.

Inventive Principle:
Principle #15Dynamics

2Reliability

If tapes are added to increase stability, then foot control improves, but the upper becomes heavier and less comfortable

Engineering Contradiction:
Improvefoot stabilityVSAvoidupper weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent uses thin, flexible tape elements made from lightweight materials that provide structural support without significant weight. These tape elements function as flexible shells that conform to the foot's shape and movements, delivering stability through their arrangement and connectivity rather than through heavy rigid structures.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The upper combines different materials with complementary properties: the base upper material provides enclosure and comfort, while the tape elements provide additional stability. This composite construction integrates materials with different functional properties to achieve both lightness and stability simultaneously.

Inventive Principle:
Principle #40Composite materials

3Reliability

If the upper material is made non-elastic for stability, then foot control improves, but wearing comfort deteriorates due to lack of stretching

Engineering Contradiction:
Improvefoot controlVSAvoidmaterial flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

By segmenting the upper into multiple movable tape elements, the patent creates a structure where each segment can independently stretch and adapt to foot movements. This segmentation allows the overall structure to maintain stability through its multi-point attachment while providing flexibility through the independent movement of each tape element.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dynamic connectivity between tape elements allows the upper to transition from a rigid stable structure to a flexible adaptive structure during movement. The tapes can shift relative to each other to accommodate foot expansion while maintaining their stabilizing function, providing both control and adaptability.

Inventive Principle:
Principle #15Dynamics
