Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors and detection methods are used to improve detection accuracy, then the reliability of detection results improves, but the device complexity increases
Solution Approach 1:
The patent combines multiple individual reliability indices (identification reliability, measurement reliability, etc.) into a single integrated reliability index through weighted summation. This merging approach maintains comprehensive assessment capability while simplifying the output structure, thereby improving reliability without proportionally increasing system complexity.
Solution Approach 2:
The integrated reliability index serves multiple functions: it evaluates both identification accuracy and measurement precision, works across different sensor types, and provides a unified metric for various detection scenarios. This multi-functionality allows the system to handle diverse detection requirements with a single standardized output.
2Reliability
If comprehensive detection information is provided to improve decision-making accuracy, then the quality of detection results improves, but the loss of time in processing increases
Solution Approach 1:
The system pre-calculates individual reliability indices for different aspects (identification, measurement, etc.) during the detection process itself, rather than computing them separately afterward. This preliminary action allows the integrated reliability index to be quickly assembled from pre-computed components, reducing additional processing time while maintaining comprehensive assessment.
3Measurement precision
If individual reliability indices for different detection aspects are calculated to improve measurement precision, then the accuracy of detection information improves, but the device complexity increases
Solution Approach 1:
The patent segments the overall reliability assessment into distinct individual indices (identification reliability, measurement reliability, etc.), each focusing on specific detection aspects. This segmentation allows precise evaluation of different detection dimensions while maintaining modular processing that reduces overall system complexity through structured decomposition.
Data Source
AI summary
An information processing apparatus includes an input interface, a processor, and an output interface. The input interface obtains observation data obtained from an observation space. The processor detects a subject image of a detection target from the observation data, calculates a plurality of individual indices indicating degrees of reliability, each of which relates to at least identification information or measurement information regarding the detection target, and also calculates an integrated index, which is obtained by integrating a plurality of calculated individual indices. The output interface outputs the integrated index.
