Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a light sensor is positioned away from the display, then the display can show eye images, but the light sensor cannot detect light beams propagated towards the pupil, creating unrealistic scenarios

Engineering Contradiction:

Improveability to simulate different eye diseases and responsesVSAvoidrealism of light detection response

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines the light sensor and display into a single integrated unit, where the light sensor is positioned directly behind the display. This merging ensures that the light sensor detects light beams propagated towards the displayed pupil, creating realistic scenarios while maintaining the ability to simulate different eye diseases and responses.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a hole as an intermediary element that allows light to pass from the external environment through the display to reach the light sensor. This intermediary structure enables the light sensor to detect light beams directed at the displayed pupil, resolving the contradiction between display functionality and light detection reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a light sensor is positioned behind the display with a fixed hole, then ambient light can be detected, but the system is limited in its ability to respond to dynamic light conditions

Engineering Contradiction:

Improvelight detection accuracyVSAvoidflexibility in simulating different eye responses

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent makes the hole position dynamic by allowing it to move or adjust based on the detected light conditions. This dynamic adjustment enables the system to respond flexibly to different light scenarios while maintaining accurate light detection, thereby improving both reliability and adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the position parameter of the hole in response to detected light intensity and patterns. By adjusting the hole position as a variable parameter, the system can adapt to different lighting conditions and simulate various eye responses, enhancing both detection accuracy and simulation flexibility.

Inventive Principle:

Principle #35Parameter changes

3Device complexity

If mechanical eyes are used, then the structure is simple, but the appearance cannot be changed to simulate different diseases or even change the color of the iris

Engineering Contradiction:

Improvestructural simplicityVSAvoidability to change appearance for different diseases

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent uses a display to create a visual copy or representation of the eye rather than using a physical mechanical eye structure. This digital copy can be dynamically changed to simulate different diseases, eye colors, and conditions, providing versatility while keeping the physical structure relatively simple.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent changes the visual parameters of the displayed eye image, such as color, shape, and pattern, to simulate different diseases and conditions. This parameter-based approach allows the same physical structure to represent multiple eye states, enhancing adaptability without increasing structural complexity.

Inventive Principle:

Principle #35Parameter changes
