Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual focusing with subjective assessment is used, then the device structure remains simple, but the focusing precision and image quality deteriorate
Solution Approach 1:
The patent replaces manual mechanical focusing with an automated autofocus system that uses a focusing lens driven by a motor (such as a voice coil motor or stepper motor). The system incorporates an image sensor and processing unit that automatically detect image sharpness and adjust the focusing lens position, eliminating the need for subjective manual assessment while maintaining relatively simple device architecture.
Solution Approach 2:
The autofocus system enables the device to focus automatically without user intervention. The processing unit continuously analyzes images captured by the image sensor and autonomously adjusts the focusing lens to achieve optimal sharpness, allowing the device to serve itself in the focusing task.
2Adaptability or versatility
If separate image capture devices are used, then the viewing and capturing functions are independent, but the overall system complexity and operation difficulty increase
Solution Approach 1:
The patent merges the viewing function (through the eyepiece and optical system) and the image capture function (through the image sensor and camera module) into a single integrated device. Both functions share common optical components including the objective lens, focusing lens, and beam path, allowing the user to view and capture images of the same target simultaneously without switching between separate devices.
Solution Approach 2:
The optical system is designed to serve multiple functions: it acts as both a viewing instrument for direct observation through the eyepiece and an image capture system for electronic recording by the image sensor. The shared optical path and components enable universal usage for both observation and documentation purposes.
3Ease of operation
If manual operation is required for focusing and image capture, then the device structure remains simple, but the ease of operation and user comfort deteriorate
Solution Approach 1:
The patent replaces manual mechanical focusing operations with an automated autofocus system controlled by a processing unit that uses image analysis to determine optimal focus. This substitution significantly improves ease of operation, as users no longer need to manually adjust focusing mechanisms while waiting for focus confirmation.
Solution Approach 2:
The autofocus system and image capture trigger system enable the device to operate with minimal user intervention. The processing unit autonomously manages focusing adjustments and can automatically trigger image capture based on detected focus quality or user input, reducing the operational burden on the user.
