Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VR equipment with screen, convex lens and step motor is used for vision training, then ciliary muscle exercise function is improved, but equipment weight increases causing user discomfort
Solution Approach 1:
The patent extracts the heavy components (screen, convex lens, step motor) from the wearable vision device and relocates them to a separate portable electronic device. The wearable device retains only the essential optical components (optical units) needed for vision training, significantly reducing its weight while preserving the core vision training functionality through wireless communication with the portable device.
Solution Approach 2:
The vision training system is segmented into two independent parts: a lightweight wearable vision device with optical units and a separate portable electronic device containing the heavy processing and display components. This segmentation allows the wearable portion to be comfortable for extended use while the portable portion provides full training capabilities.
2Adaptability or versatility
If screen is disposed close to user's eyes in VR equipment, then vision training effectiveness is improved, but risk of eye diseases increases
Solution Approach 1:
The screen is extracted from the wearable vision device and placed in a separate portable electronic device that the user holds at a safe distance. This eliminates the need to position the screen close to the eyes, removing the harmful effect while preserving vision training effectiveness through the optical units' light deflection control.
3Ease of operation
If manual user input is required for vision training setup, then device operation control is improved, but ease of operation deteriorates especially for young children
Solution Approach 1:
The portable electronic device automatically captures user information (such as photos or video feeds) and uses image recognition technology to extract relevant vision training parameters. This self-service approach eliminates manual input requirements, making the device accessible to young children and non-technical users while maintaining precise control over training parameters.
Solution Approach 2:
The manual input mechanism is replaced with an automated optical recognition system. Instead of requiring users to manually enter information through buttons or keyboards, the system uses the camera and image processing algorithms to automatically capture and analyze user characteristics, substituting mechanical interaction with optical-field-based automation.
4Device complexity
If VR equipment displays limited objects for training, then device complexity is reduced, but training effectiveness and user engagement deteriorate
Solution Approach 1:
The portable electronic device serves multiple functions: it acts as both the vision training device and a universal media player capable of displaying various video sources including educational content, entertainment videos, and interactive games. This multi-functionality provides diverse and engaging training content without increasing the complexity of the wearable vision device itself.

AI summary
A method for implementing vision training is implemented using a portable electronic device and a vision device that includes two optical units that are arranged in front of two eyes of the user, respectively. The method includes: displaying an icon on the portable electronic device to enable the user to see through the vision device a clear image of the icon; controlling the optical units to dynamically adjust a physics variable; in response a user-input termination command indicating that the user sees two blurry images of the icon, determining a current physics variable of each of the optical units; calculating a test score based on the current physics variables of the optical units; and initiating a vision training session that includes playing a video source and controlling the optical units to adjust the physics variable in one of a refractive error process and a recovery process.
