Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current device management systems, such as OMA DM, require user-initiated error reporting, which can lead to delayed error detection and handling due to user knowledge limitations and passive software developer responses, restricting the operators' ability to obtain terminal errors efficiently.
Innovation Solution
A method and system where terminal devices automatically report information through a DM Agent module to a DM Server, using extended OMA DM protocols, enabling active event-triggered messaging or adding special commands to facilitate timely and accurate error reporting and automatic fault resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If color difference is used as a scalar value in pattern search, then the pattern search process can be executed in color images, but the directional aspect of color distribution is ignored leading to false detections
Solution Approach 1:
The patent transforms the scalar color difference into a vector quantity by introducing directional information. The color difference is represented as a vector in color space that includes both magnitude and direction components, allowing the pattern search to consider the directional aspect of color distribution. This dimensional enhancement resolves the contradiction by maintaining color image processing capability while improving pattern matching accuracy through vector-based comparison.
Solution Approach 2:
The patent changes the parameter representation from scalar color difference to vector color difference. By transforming the single-value color difference metric into a multi-component vector that preserves directional information, the system maintains versatility in color image processing while eliminating false detections caused by ignoring color distribution direction. This parameter transformation directly addresses the accuracy issue without sacrificing adaptability.
2Device complexity
If normalized correlation value calculation ignores even concentration components, then calculation is simplified, but regions with similar relative color distribution but different absolute colors are mistakenly detected
Solution Approach 1:
The patent performs preliminary subtraction of even concentration components before calculating the normalized correlation value. By removing the uniform color component in advance, the calculation focuses only on the varying color distribution patterns. This preliminary action maintains computational simplicity while improving detection accuracy, as the correlation calculation now compares only the meaningful variable color patterns rather than being influenced by uniform background colors.
Solution Approach 2:
The patent extracts and separates the even concentration component from the color image data before performing pattern matching. By taking out the uniform color component that causes false correlations, the system maintains simplified calculation while improving reliability. The extraction isolates the relevant color distribution variations that truly indicate pattern matches, eliminating misleading correlations from uniform color regions.
3Adaptability or versatility
If relative color distribution comparison is used, then color variations are tolerated, but absolute color matching precision is lost causing false positives
Solution Approach 1:
The patent enhances the comparison from scalar to vector by incorporating directional information about color distribution. The vector representation preserves both the relative color relationships (providing variation tolerance) and the absolute color orientation (providing matching precision). This dimensional enhancement allows the system to distinguish between legitimate color variations and false positives by considering the direction of color differences in color space.
