Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems face difficulties in managing state quantity values for maintenance and monitoring due to overlapping values and challenges in appropriately specifying reliable values for device management.
Innovation Solution
An information processing device that acquires and processes state quantity values from multiple measurement instruments, using an extraction unit to group values by identical state quantities and a specification unit to select values based on reliability, ensuring accurate management even with overlapping data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple measurement instruments measure the same state quantity, then measurement coverage and redundancy are improved, but data management complexity and reliability assessment difficulty increase
Solution Approach 1:
The patent segments the management of multiple measurement values by introducing an extraction unit that separates and groups values belonging to the same state quantity. This segmentation allows the system to handle multiple measurements systematically by organizing them into structured groups, thereby reducing management complexity while maintaining reliability through comprehensive data collection.
Solution Approach 2:
The specification unit acts as an intermediary between the multiple measurement values and the final state quantity determination. It introduces reliability as an intermediate assessment criterion, evaluating each measurement value's reliability and selecting the most appropriate one. This intermediary mechanism resolves the contradiction by providing a systematic way to handle redundancy without increasing management complexity.
2Loss of information
If multiple values for identical state quantity are collected, then data completeness is improved, but difficulty in specifying reliable values increases
Solution Approach 1:
The patent implements a feedback mechanism where the specification unit continuously evaluates measurement values based on reliability criteria. The system feeds back reliability assessments to determine which values to adopt, creating a closed-loop process that systematically resolves the difficulty of specifying reliable values while maintaining data completeness through comprehensive collection and evaluation.
Solution Approach 2:
The patent changes the parameter used for value selection from simple temporal or arbitrary selection to reliability-based selection. By introducing reliability as the key parameter for specifying which value to adopt, the system transforms the value specification process from a difficult subjective judgment to an objective parameter-driven decision, thereby reducing specification difficulty while maintaining data completeness.
3Quantity of substance
If all acquired values are used for management, then information completeness is improved, but processing load and analysis complexity increase
Solution Approach 1:
The extraction unit extracts and identifies values belonging to the same state quantity from the acquired measurement data. This extraction process organizes the information by state quantity, allowing the system to maintain information completeness while reducing processing load by grouping related values together for systematic handling rather than processing them as individual isolated data points.
Solution Approach 2:
Instead of processing all acquired values equally, the patent applies partial action by selectively specifying only the necessary values for management based on reliability assessment. The specification unit determines which values within each group are most appropriate for management purposes, avoiding the excessive processing of all available data while maintaining sufficient information completeness for effective device management.
