Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complete evaluation device with image processing and analysis capabilities is integrated into a single portable unit, then measurement precision and reliability are improved, but device complexity and cost increase significantly

Engineering Contradiction:
Improveevaluation reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The evaluation system is divided into two separate components: a simple portable reading device for image acquisition and a remote analysis device for image processing and analysis. This segmentation allows the reading device to remain simple and portable while the analysis functions are performed remotely, resolving the contradiction between reliability and device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A communication interface serves as an intermediary between the reading device and the analysis device, transmitting image data from the portable device to the remote analysis system. This intermediary enables the separation of functions while maintaining system integration and reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If calibration data is stored locally in each evaluation device, then measurement precision is improved, but manufacturing complexity and cost increase due to dedicated calibration requirements

Engineering Contradiction:
Improveanalyte evaluation precisionVSAvoidmanufacturing complexity
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The analysis device is designed to be universal and can process images from multiple different immunochromatographic devices. By centralizing the analysis function, the system eliminates the need for each device to have dedicated calibration data, simplifying manufacturing while maintaining precision through centralized calibration management.

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

Solution Approach 2:

Instead of embedding calibration data in each device, the system uses a centralized analysis device that can handle and process images from multiple sources. This copying approach allows the same analysis algorithm and calibration to be applied across different devices, reducing manufacturing complexity.

Inventive Principle:
Principle #26Copying

3Reliability

If analysis is performed locally on each device, then reliability is improved, but adaptability and scalability are reduced when pooling results for clinical trials

Engineering Contradiction:
Improveanalysis reliabilityVSAvoidresult pooling capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system merges the analysis functions into a centralized remote device that can process results from multiple reading devices. This combination enables result pooling and centralized management, improving adaptability for clinical trials while maintaining reliability through consistent analysis protocols applied across all devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The centralized analysis device provides feedback and standardized processing to multiple reading devices, ensuring consistent and reliable analysis across the network. This feedback mechanism maintains reliability while enabling scalable result pooling and centralized control.

Inventive Principle:
Principle #23Feedback
