Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial eyes for training purposes lack flexibility and realism, as they cannot accurately simulate different eye diseases or respond realistically to light conditions due to mechanical limitations and unrealistic light sensor placement.
Innovation Solution
An artificial eye system featuring a display unit with light cells that can both emit and detect light, controlled by a system that adjusts the image of the eye based on detected light patterns and patient profiles, allowing for dynamic simulation of eye characteristics and reactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical eyes with motorized pupils or irises are used, then the appearance can be changed according to light intensity, but the system lacks flexibility to simulate different diseases or change iris color and produces noise
Solution Approach 1:
The patent replaces the mechanical eye system with motors and moving parts with a display-based system using light cells (LEDs or similar). The display unit shows images of eyes with varying pupil sizes, iris colors, and pathological conditions without any mechanical movement. This substitution eliminates noise, reduces complexity, and increases versatility to simulate different diseases and eye conditions.
Solution Approach 2:
The system changes the parameters displayed on the screen (pupil diameter, iris color, presence of pathological features) to simulate different eye conditions and responses to light. By varying these visual parameters through software control of the light cells, the system achieves adaptability without mechanical complexity.
2Reliability
If a separate light sensor is positioned away from the display, then light detection can be implemented, but the system creates unrealistic scenarios where the sensor cannot detect light directed at the displayed eye
Solution Approach 1:
The patent merges the light detection function directly into the display unit by making certain light cells capable of both emitting and detecting light. When these light cells are in the off state, they can detect incident light, creating a realistic scenario where the eye responds to light directed at it. This integration eliminates the unrealistic gap between display and sensor that exists in separate-component designs.
Solution Approach 2:
The light cells are designed with multi-functionality, serving both as display elements (when emitting light) and as light sensors (when detecting incident light). This universal function allows the same component to both show the eye image and detect light directed at it, enhancing realism while reducing overall system complexity.
3Adaptability or versatility
If displays are used to simulate eyes, then the appearance can be modified to simulate different diseases, but the system lacks realistic light detection capability when light is directed at the displayed eye
Solution Approach 1:
The patent combines the display function and light detection function into the same light cell structure. The display unit shows eye images with various pathological conditions, while simultaneously being capable of detecting incident light through the same or adjacent light cells. This merging ensures that the system both displays eye conditions and realistically responds to light directed at the displayed eye.
Solution Approach 2:
The system implements feedback by having the light cells detect incident light and use this information to adjust the displayed eye image in real-time. When light is detected, the system modifies the pupil size or other eye parameters to simulate a realistic physiological response, creating a closed-loop system that enhances both adaptability and realism.
