Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data entry is performed using a computer mouse to copy and paste text, then data transfer between user interfaces is achieved, but the process is tedious and time-consuming with degraded accuracy due to repetitive tasks
Solution Approach 1:
The patent replaces manual mechanical operations (mouse clicking, highlighting, copying, pasting) with an automated optical system. The smart contact lens captures images of source and destination UIs, and the system automatically identifies and transfers data fields, eliminating the need for manual mechanical data entry operations.
Solution Approach 2:
The system enables self-service data entry by automatically capturing the user's gaze direction, identifying relevant data fields in source and destination UIs, and performing the copy-paste operation without requiring manual intervention. The system serves itself by using the user's natural eye movements as input signals.
2Reliability
If manual copying and pasting is used for data entry, then data transfer is accomplished, but accuracy degrades over time due to the repetitive nature of the tasks
Solution Approach 1:
The patent replaces error-prone manual operations with an automated computer vision system that consistently identifies and transfers data fields. The system processes images captured by the smart contact lens to automatically match source and destination fields, eliminating human error from repetitive copy-paste operations.
Solution Approach 2:
The system incorporates feedback mechanisms by continuously monitoring the user's gaze direction and eye movements. The captured images and gaze data are processed to provide real-time feedback on which fields are being viewed, allowing the system to automatically adjust and confirm data transfer operations, thereby maintaining high accuracy.
3Ease of operation
If smart contact lenses with multiple components (micro camera, memory unit, sensors, LED) are used, then hands-free data capture and transmission is enabled, but device complexity increases
Solution Approach 1:
The patent merges multiple functional components (micro camera for image capture, memory unit for data storage, sensors for gaze tracking, and LED for light-based communication) into a single smart contact lens device. This integration enables hands-free operation while consolidating what would otherwise be separate devices into one wearable unit.
Solution Approach 2:
The smart contact lens is designed as a multi-functional device that simultaneously performs image capture, gaze tracking, data storage, and wireless communication through LiFi. This universal design allows a single device to replace multiple separate tools, justifying the increased component density through its versatile capabilities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates fast, accurate, and efficient data transfer between user interfaces, reducing the burden of repetitive tasks and enhancing data entry precision through real-time parallel processing and secure LiFi transmission.
Implementation Method 1
The transmission may be leveraged by light fidelity ('Lifi'). The smart contact lens may include a light emitting diode ('LED') attached to a substrate on the smart contact lens. The LED may be connected to a microcontroller. The LED may be operable to transmit the data captured at the first UI to the second terminal.
Data Source
AI summary
Systems and methods for transferring data via a smart contact lens from a first user interface (“UI”) to a second UI is provided. Methods may include triggering a tracking of the focus of the user's eyes on the first UI and further tracking a start point and an end point of the focus of the user's eyes based on detection of deliberate blink gestures. Methods may further include capturing a segment of data within the start point of focus and the end point of focus and storing the segment of data in memory on the smart contact lenses. Methods may further include updating the second UI based on an instruction in a data packet transmitted to the second UI, by inputting the segment of data at a point of focus of the user's eye on the second UI.
