Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional stationary retinal cameras are used for eye imaging, then high quality images can be obtained, but professional operation and manual alignment are required, reducing ease of operation

Engineering Contradiction:
Improveimage qualityVSAvoidoperation requirement
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The mobile imaging device enables self-examination by automatically performing alignment and image capture without requiring professional operation. The system includes a processor that automatically processes captured images to determine alignment quality and provides feedback to the user for realignment, allowing the user to independently obtain high-quality eye images.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system provides real-time feedback to the user regarding image quality and alignment status. The processor analyzes captured images and communicates alignment quality to the user, enabling iterative self-adjustment to achieve optimal image quality without professional intervention.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If hand-held imaging devices are used for retinal screening, then ease of operation is improved, but precise alignment by a second person is still required, increasing device complexity

Engineering Contradiction:
ImproveportabilityVSAvoidalignment requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mobile device performs self-alignment by automatically processing captured images to determine alignment quality. The system eliminates the need for a second person to perform alignment by incorporating automated image analysis and user feedback mechanisms that guide the user to achieve proper alignment independently.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces manual mechanical alignment performed by a second person with automated electronic image processing and analysis. The processor automatically evaluates alignment quality based on captured images and provides digital feedback, substituting the mechanical alignment process with an automated computational approach.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If professional clinicians perform eye examinations, then image quality is ensured, but regular visits to doctor's office are required, increasing loss of time

Engineering Contradiction:
Improveimage qualityVSAvoidvisit frequency
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The mobile imaging device enables users to perform self-examinations at home, eliminating the need for regular visits to the doctor's office. The automated image capture and analysis functions allow users to independently monitor their eye health over time, significantly reducing time loss associated with travel and scheduling appointments.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system enables continuous monitoring of eye health by allowing users to capture and analyze images at any time without interruption. This continuous capability replaces periodic professional examinations with ongoing self-monitoring, maintaining image quality assessment without time loss from regular visits.

Inventive Principle:
Principle #20Continuity of useful action

4Ease of operation

If automated image quality determination is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveautomation levelVSAvoidprocessing capability
Core Design Contradiction:
