Multi-Lens Vision Training for Personalized Accommodation Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vision training devices fail to consider individual accommodative facility and accommodation time variations among users, leading to uncomfortable training experiences and suboptimal results due to uniform training times that do not align with user-specific lens adaptation times.
Innovation Solution
A vision training device that includes a lens holder movable with respect to a main body, a drive motor for switching lenses with different diopters, a user input unit, and a control unit to manage accommodation times based on user input or sensor feedback, allowing personalized training modes and accurate measurement of accommodative facility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single lens is used in the vision training device, then the device structure is simple, but the training effectiveness and versatility are limited
Solution Approach 1:
The lens unit is divided into multiple independent lenses with different diopter values, each capable of being independently positioned on the line of sight axis. This segmentation allows the system to provide multiple training scenarios (different accommodation distances) while maintaining a relatively simple overall structure, as each lens operates independently rather than requiring complex integrated mechanisms.
Solution Approach 2:
The lens holder is designed to be movable along the line of sight axis, allowing dynamic selection of which lens is active. The drive motor enables the lens holder to move between positions, making the system adaptable to different training requirements. This dynamic capability provides versatility without requiring multiple fixed lens assemblies, thus managing complexity while improving training effectiveness.
2Ease of operation
If manual selection of lenses is used, then the device structure is simple, but the operation convenience and training efficiency are reduced
Solution Approach 1:
The system automatically selects and positions the appropriate lens based on training parameters stored in memory, eliminating the need for manual lens selection by the user. The control unit autonomously manages the drive motor to position the correct lens on the line of sight axis, making the operation more convenient and efficient while the automated control handles the complexity of lens management.
Solution Approach 2:
The control unit stores training parameters and automatically adjusts lens positioning based on pre-programmed sequences or user inputs. This feedback mechanism ensures that the correct lens is selected and positioned without requiring manual intervention, improving ease of operation while the automated feedback loop manages the system complexity.
3Adaptability or versatility
If multiple lenses are positioned simultaneously on the line of sight axis, then the training versatility is improved, but the device complexity and space requirements increase
Solution Approach 1:
Each lens is positioned in a separate, discrete location along the line of sight axis, allowing multiple lenses to be stored and accessed independently. This segmentation enables the system to provide multiple training scenarios (different accommodation distances) while maintaining manageable complexity, as each lens position can be controlled independently rather than requiring a complex continuous adjustment mechanism.
Solution Approach 2:
The lens holder moves along the line of sight axis (adding a spatial dimension) to position different lenses. By utilizing the depth dimension along the optical axis rather than requiring lateral movement or rotation, the system can accommodate multiple lenses without increasing lateral complexity. This dimensional approach allows multiple training scenarios while keeping the mechanism relatively simple and space-efficient.
