Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods such as rulers and measuring tapes are used to assess bald areas, then the assessment process is simple and accessible, but the measurement precision and accuracy are inadequate
Solution Approach 1:
The patent replaces traditional mechanical measurement tools (rulers, measuring tapes) with a digital imaging system that uses a camera to capture images of the scalp and automatically calculates surface area through image processing algorithms. This substitution of mechanical systems with optical and computational systems resolves the contradiction by providing high measurement precision without requiring complex manual measurement devices.
Solution Approach 2:
The patent creates a digital copy (image) of the scalp surface and performs measurements on this copy rather than directly on the physical scalp. This allows for precise automated calculation of surface area while keeping the actual measurement device (camera) relatively simple and non-invasive.
2Measurement precision
If qualitative assessment methods such as the Norwood-Hamilton Scale are used, then the classification of baldness is standardized and widely recognized, but the quantitative measurement of bald surface area is not provided
Solution Approach 1:
The system performs automatic image processing and area calculation without requiring manual intervention for measurement. The software automatically detects scalp boundaries, calculates surface area, and provides quantitative results, making the process self-service and eliminating the need for complex manual measurement procedures while maintaining ease of operation.
Solution Approach 2:
The patent transforms the assessment from purely qualitative classification (Norwood-Hamilton scales) to quantitative measurement by introducing surface area calculation as a new parameter. This allows clinicians to obtain both the standardized classification and precise numerical measurements of bald area, combining the benefits of both approaches.
3Reliability
If existing assessment methods are used, then the evaluation process is quick and simple, but the accuracy in determining the exact dimension of scalp requiring surgical intervention is insufficient
Solution Approach 1:
The patent performs preliminary quantitative assessment of bald surface area before surgical planning, providing accurate measurements that guide the entire treatment process. This preliminary action ensures reliable data is available for surgical planning, reducing the need for repeated assessments and adjustments during the procedure.
Solution Approach 2:
By replacing manual measurement methods with automated image processing, the system achieves high reliability in measurements without significantly increasing procedure time. The automated calculation instantaneously processes images and provides results, eliminating the time-consuming nature of manual measurements while ensuring accuracy.
