Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional footwear is used without fluid pressure control, then the structure is simple and manufacturing is easy, but foot support pressure cannot be dynamically adjusted leading to discomfort and performance issues

Engineering Contradiction:
Improvefoot support pressure adjustmentVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic foot support pressure adjustment through a fluid distribution system with a manifold and multiple valves that can actively change pressure levels in different foot regions based on real-time needs, transforming static footwear into a dynamic, adaptive system

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The footwear is divided into multiple independent foot support regions (heel, toe, midfoot) with individually controllable fluid-filled bladders, allowing selective pressure adjustment in specific areas through a segmented control system

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If fluid pressure control system is added to footwear, then foot support pressure can be dynamically adjusted, but the device complexity increases with manifold, valves, and fluid containers

Engineering Contradiction:
Improvepressure controlVSAvoidsystem components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The fluid distribution manifold serves multiple functions simultaneously: it distributes fluid to multiple foot regions, collects fluid from regions, and integrates with the pump system, reducing the need for separate dedicated components for each function

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the fluid storage container, pump mechanism, and distribution manifold into an integrated foot support system that is embedded within the footwear structure, merging multiple functional components into a unified system

Inventive Principle:
Principle #5Merging (Combining)
