Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual adjustment and fixed positioning of measurement equipment is used, then measurement accuracy can be ensured, but the time and physical effort required for each measurement increases significantly

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidtime required for measurement

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system automatically determines the user's body measurements and joint positions using sensors and image processing, eliminating the need for manual measurement and positioning by medical staff. The equipment self-adjusts based on automatically captured body data.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Manual mechanical adjustment of equipment positioning is replaced with automated sensor-based detection and computer-controlled positioning systems that automatically determine optimal measurement positions based on user body characteristics.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If manual adjustment and fixed positioning of measurement equipment is used, then measurement accuracy can be ensured, but the physical effort required for each measurement increases significantly

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidphysical effort

Core Design Contradiction:

Measurement precisionVSForce

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If hardware settings cannot be remembered between measurements, then equipment simplicity is maintained, but repeated measurements require repeating the entire setup process

Engineering Contradiction:

Improveequipment simplicityVSAvoidmeasurement efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The system stores user body measurement data and measurement settings in a database, automatically retrieving and applying previously stored information for subsequent measurements, eliminating the need to repeat setup procedures while maintaining system simplicity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

User body measurements and equipment settings are captured and stored in advance, so that when the same user returns for repeated measurements, the system automatically applies the pre-stored settings without requiring re-measurement or reconfiguration.

Inventive Principle:

Principle #10Preliminary action

4Adaptability or versatility

If accessory modules are manually replaced for different joint measurements, then measurement versatility is achieved, but the time and physical effort for module replacement increases

Engineering Contradiction:

Improvemeasurement versatilityVSAvoidtime for module replacement

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

A single integrated measurement system with adjustable components can measure multiple joint types (shoulder, elbow, wrist, hip, knee, ankle) by programmatically changing measurement parameters and positioning, eliminating the need for separate heavy accessory modules for each joint.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The measurement system dynamically adapts its configuration and parameters based on the target joint being measured, allowing one piece of equipment to perform multiple measurement functions through software control rather than physical module changes.

Inventive Principle:

Principle #15Dynamics

5Adaptability or versatility

If accessory modules are manually replaced for different joint measurements, then measurement versatility is achieved, but the physical effort for module replacement increases

Engineering Contradiction:

Improvemeasurement versatilityVSAvoidphysical burden on evaluator

Core Design Contradiction:

Adaptability or versatilityVSForce

Solution Approach 1:

Inventive Principle:
