Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional analog optometric devices are used to prescribe progressive lenses, then the prescription process is simple and quick, but patients cannot experience the progressive lens effects before purchase leading to high return rates
Solution Approach 1:
The system performs preliminary simulation of progressive lens effects before the actual lens is manufactured. Patients use the simulator to experience different lens designs, corridor lengths, and power distributions in advance, allowing them to make informed decisions and reducing the need for return visits.
Solution Approach 2:
The system creates a virtual copy of the progressive lens experience through digital simulation. The progressive lens simulator reproduces the optical effects, distortion patterns, and visual experiences of actual progressive lenses, allowing patients to test-drive lens designs without physical trial frames.
2Adaptability or versatility
If only two distances (near and distance) are tested during prescription, then the examination process is quick, but it does not account for patients' unique usage patterns at multiple distances
Solution Approach 1:
The system transitions from static two-distance testing to dynamic multi-distance simulation. Patients can interactively adjust gaze distances and explore visual experiences at intermediate distances (computer work, dashboard viewing, etc.), allowing the examination to adapt to individual usage patterns while maintaining efficiency through automated guidance.
3Manufacturing precision
If progressive lens design optimization uses only 2-3 patient parameters, then the prescription process is efficient, but the lens design is under-defined and cannot achieve true optimization
Solution Approach 1:
The system implements feedback loops where patient responses to simulated lens designs inform subsequent design adjustments. The progressive lens simulator captures detailed feedback on visual comfort, distortion perception, and preference across multiple distances, which feeds back into the optimization algorithm to refine lens parameters beyond the traditional 2-3 measurements.
4Productivity
If modern optoelectronic technologies and AI are integrated into the prescription system, then lens design optimization and patient experience improve, but the system complexity and initial treatment time increase
Solution Approach 1:
The progressive lens simulator is designed to guide patients through self-directed exploration of lens designs. The system automatically presents different lens options, captures patient feedback, and adjusts simulations without requiring extensive optometrist intervention, allowing the complex technology to serve itself while reducing ongoing operational complexity.

AI summary
A Progressive Lens Simulator comprises an Eye Tracker, for tracking an eye axis direction to determine a gaze distance, an Off-Axis Progressive Lens Simulator, for generating an Off-Axis progressive lens simulation; and an Axial Power-Distance Simulator, for simulating a progressive lens power in the eye axis direction. The Progressive Lens Simulator can alternatively include an Integrated Progressive Lens Simulator, for creating a Comprehensive Progressive Lens Simulation. The Progressive Lens Simulator can be Head-mounted. A Guided Lens Design Exploration System for the Progressive Lens Simulator can include a Progressive Lens Simulator, a Feedback-Control Interface, and a Progressive Lens Design processor, to generate a modified progressive lens simulation for the patient after a guided modification of the progressive lens design. A Deep Learning Method for an Artificial Intelligence Engine can be used for a Progressive Lens Design Processor.
