Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional foot therapy devices are used, then therapy function is provided, but the device is not ergonomic and cannot be used while walking

Engineering Contradiction:

Improveusability while walkingVSAvoidtherapy effectiveness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The insert is designed with flexible material that allows it to dynamically adapt to foot movements and pressure changes during walking, while maintaining its therapeutic function through controlled deformation and recovery

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If foot therapy devices are made customizable, then user needs are met, but device complexity increases

Engineering Contradiction:

ImprovecustomizabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The therapy device is segmented into a reusable base and interchangeable inserts, allowing customization through different inserts while keeping the base structure simple and unchanged

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A single base design serves multiple therapeutic purposes by accepting various inserts with different functions, making the base universal while the inserts provide specialized customization

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If secure coupling mechanism is added, then insert stability is improved, but manufacturing complexity increases

Engineering Contradiction:

Improveinsert retentionVSAvoidmanufacturing simplicity

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The insert utilizes its flexible material properties to create a secure coupling through elastic deformation and friction, eliminating the need for rigid mechanical fastening components

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The flexible insert automatically secures itself to the base through elastic recovery force when inserted, without requiring additional locking mechanisms or assembly steps

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If interchangeable components are added, then customization is enabled, but device complexity increases

Engineering Contradiction:

ImproveinterchangeabilityVSAvoidcomponent system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into modular components (base and inserts) that can be independently manufactured and assembled, enabling interchangeability while keeping each component's structure simple

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base is designed as a universal platform that can accommodate multiple types of inserts, achieving interchangeability without requiring complex adaptive mechanisms in the base

Inventive Principle:

Principle #6Universality (Multi-functionality)
