Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional glasses with fixed focal length lenses are used, then the structure is simple and easy to manufacture, but the vision is indistinct and eyes get tired when viewing objects at distances beyond the correction range
Solution Approach 1:
The patent applies dynamics by making the lens focal length adjustable rather than fixed. The lens module can dynamically change its focal length based on the distance to the observed object, allowing the glasses to adapt to different viewing distances and maintain clear vision across a broader range, thus resolving the contradiction between vision reliability and distance adaptability
Solution Approach 2:
The patent changes the optical parameter (focal length) of the lens dynamically. By adjusting the focal length parameter according to the object distance, the system maintains clear imaging for objects at various distances, solving the problem of limited correction range while preserving vision quality
2Adaptability or versatility
If multi-focus glasses with multiple focal lengths are used, then the correction range for different distances is improved, but the device complexity increases and manual adjustment is required
Solution Approach 1:
The patent implements self-service by enabling the lens module to automatically detect the distance to the observed object and adjust its own focal length accordingly. This eliminates the need for manual adjustment by the user while maintaining a relatively simple lens structure, thus improving adaptability without proportionally increasing complexity
Solution Approach 2:
The system uses feedback by detecting the distance to the observed object and using this information to automatically adjust the lens focal length. This closed-loop control allows the glasses to maintain clear vision across different distances without requiring complex manual intervention or overly complicated lens mechanisms
3Adaptability or versatility
If multi-focus glasses with segmented lenses are used, then the correction for different distances is improved, but the ease of operation deteriorates due to the need to manually adjust position
Solution Approach 1:
The lens module performs self-adjustment by automatically detecting the object distance and changing its focal length correspondingly. This eliminates the need for users to manually adjust the position or configuration of the lenses, maintaining ease of operation while providing adaptive focus for different distances
4Adaptability or versatility
If an electronically adjustable lens is used, then the focal length can be adjusted, but automatic detection and adjustment based on user's eye focus is not implemented
Solution Approach 1:
The system implements automatic focus detection by using a sensor to detect the user's eye focus state and using this feedback to automatically adjust the lens focal length. This creates a closed-loop system where the lens adapts to the user's viewing needs without manual intervention, achieving both focal length adjustability and high automation
Solution Approach 2:
The lens system serves itself by automatically detecting the required focal length based on object distance or eye focus state and adjusting its own parameters accordingly. This eliminates the need for manual control while providing adaptive focus, thereby increasing the extent of automation
