Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical lens system is used to achieve higher magnification, then magnification capability is improved, but device weight and size increase making it inconvenient to use
Solution Approach 1:
The patent replaces the traditional optical lens system with a digital imaging system consisting of a camera, image sensor, and digital processing unit. This substitution eliminates the need for large, heavy optical lenses while achieving higher magnification through digital zoom and image processing algorithms, directly resolving the contradiction between magnification capability and device weight.
Solution Approach 2:
The patent creates a digital copy of the observed object through the camera and image sensor, then processes this digital copy to achieve magnification. Instead of using optical lenses to physically magnify the object, the system captures an image and digitally enlarges it, maintaining lightweight design while providing high magnification capability.

3Ease of operation
If optical loupes are customized to fit human eye pupil distance and eye vision, then usability is improved, but device complexity and customization requirements increase
Solution Approach 1:
The patent designs a universal mounting structure that can accommodate different camera sizes and configurations without requiring custom adjustments for each user. The adjustable mounting mechanism allows the device to adapt to various eye positions and prescriptions, providing a one-size-fits-all solution that maintains ease of use while reducing customization complexity.
Solution Approach 2:
The patent incorporates an adjustable mounting structure that allows dynamic positioning of the camera and display relative to the user's eyes. This dynamic adjustment capability enables a single device to adapt to different users' anatomical variations and preferences, achieving high usability without requiring multiple customized units.
