Innovation Solution
A vision recovery training device with a housing that includes a pair of rotation modules, each containing a rotation disc with a magnetic body and a sensor module, which accurately identifies the position of different diopter lenses to prevent initial position errors and enhance vision without additional glasses, using a Hall sensor to detect magnetic changes and maintain the correct diopter setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotation modules with driving motors are used to change diopter lenses, then vision recovery training functionality is improved, but initial position setting errors occur causing malfunction
Solution Approach 1:
The patent applies preliminary action by pre-setting the initial position of the rotation disc using a magnetic body as a reference marker before operation begins. The sensor module detects this pre-positioned magnetic body to establish the starting position, ensuring accurate diopter lens alignment from the beginning of vision recovery training without requiring manual calibration during operation.
Solution Approach 2:
The patent implements feedback through a sensor module that continuously monitors the position of the rotation disc by detecting the magnetic body. This feedback mechanism ensures the rotation disc returns to and maintains the correct initial position, preventing positioning errors and enabling reliable automatic control of diopter lens changes during vision recovery training.
2Productivity
If multiple diopter lenses are rotated to train eye muscles, then vision improvement effectiveness is enhanced, but position detection accuracy deteriorates without proper sensing mechanisms
Solution Approach 1:
The patent replaces complex mechanical position detection mechanisms with a magnetic field-based sensing system. A magnetic body is attached to the rotation disc, and a Hall sensor or similar magnetic sensor detects its position without mechanical contact. This substitution maintains high measurement precision while enabling smooth, contactless rotation of multiple diopter lenses for effective vision training.
Solution Approach 2:
The patent introduces a magnetic body as an intermediary between the rotation disc and the sensor module. This magnetic intermediary carries position information from the rotating disc to the stationary sensor, enabling accurate position detection without direct mechanical coupling. This allows multiple diopter lenses to be rotated precisely for vision training while maintaining reliable position measurement.
