Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of optical and digital zoom is used, then the medical image can be optimized for the display, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system automatically determines the display dimensions and calculates the optimal zoom factor without user intervention. The processor receives display dimension information, computes the appropriate optical and digital zoom settings, and adjusts the imaging system automatically, allowing the system to serve itself rather than requiring manual operation.
Solution Approach 2:
The system pre-determines the optimal zoom settings by first receiving display dimension information and calculating the required zoom factor before actual image display. This preliminary calculation of zoom parameters based on display characteristics enables immediate optimal image presentation without requiring manual adjustment during operation.
2Extent of automation
If automatic zoom adjustment is implemented, then user intervention is reduced, but the system complexity increases
Solution Approach 1:
The processor performs multiple functions: receiving display dimension information, calculating optimal zoom factors, controlling optical zoom, and coordinating digital zoom. By consolidating these functions into a single processing unit that already handles image processing and system coordination, the patent achieves automatic zoom adjustment without proportionally increasing overall system complexity.
Solution Approach 2:
The system uses an intermediary processing step where the processor calculates the optimal zoom factor based on display dimensions before applying the zoom. This mathematical calculation acts as a simple intermediary that translates display characteristics into appropriate zoom settings without requiring complex mechanical or optical mechanisms.
3Manufacturing precision
If optical and digital zoom are both used for image optimization, then the image can be properly sized, but the device complexity increases
Solution Approach 1:
The system dynamically adjusts the combination of optical and digital zoom based on the calculated optimal zoom factor. The processor determines the appropriate split between optical zoom (via lens adjustment) and digital zoom (via image processing), allowing flexible dynamic adjustment rather than fixed mechanical arrangements, thereby achieving precise image sizing with adaptable complexity.
Solution Approach 2:
The system changes parameters (optical zoom level and digital zoom level) to achieve the desired image size. By controlling the optical zoom through lens parameter adjustment and digital zoom through image processing parameters, the system achieves precise image sizing through parameter optimization rather than complex mechanical reconfiguration.
