Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a user manually determines the extent of damage to a vehicle, then the accuracy of damage assessment can be maintained through human judgment, but the process requires human intervention and is time-consuming
Solution Approach 1:
The damage detection process is segmented into multiple specialized detection modules: damaged area detector, damage depth detector, and damage characteristic detector. Each module focuses on a specific aspect of damage analysis, enabling comprehensive automated assessment while maintaining high precision through divided functional responsibilities.
Solution Approach 2:
The system transitions from two-dimensional image analysis to three-dimensional damage assessment by detecting damage depth in addition to damaged area and characteristics. This dimensional expansion enables more accurate automated evaluation of damage extent without requiring human intervention.
2Productivity
If detailed damage information is detected without human intervention, then the efficiency of repair cost estimation is improved, but the complexity of the detection system increases
Solution Approach 1:
The detection system is designed with multi-functional detectors that can identify multiple damage attributes (area, depth, characteristics) simultaneously from the same input data. This universal approach enables comprehensive damage assessment through a unified system rather than multiple separate devices, managing complexity while improving productivity.
Solution Approach 2:
The system introduces an intermediary processing layer that extracts feature amounts from vehicle images and feeds them to multiple detection modules. This intermediary feature extraction stage simplifies the overall system architecture by preprocessing data into standardized features that can be used across different detection functions.
3Measurement precision
If only basic damage detection is performed, then the system complexity remains low, but the accuracy of repair cost estimation is insufficient
Solution Approach 1:
The system applies local quality analysis by detecting specific damage characteristics at different locations and depths within the damaged area. Rather than treating all damage uniformly, the system analyzes local variations in damage depth and characteristics to provide precise assessment for repair cost estimation.
Solution Approach 2:
The system enhances basic damage detection by adding the depth dimension to the analysis. By detecting damage depth in addition to damaged area and characteristics, the system transforms simple 2D image analysis into comprehensive 3D damage assessment, significantly improving accuracy for repair cost estimation.
