Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to appropriately utilize measurement data from sensors for monitoring industrial machines.
Innovation Solution
A logging apparatus that acquires and records measurement and operation data from sensors, and transmits it to an external apparatus at specified timings, utilizing a control unit to manage power supply interruptions and ensure data continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement data is continuously collected and stored, then monitoring capability is improved, but storage requirements and data management complexity increase
Solution Approach 1:
The patent extracts and transmits only essential measurement data to external devices at specified timings, separating the data collection function from the data storage and analysis function. This allows the logging device to maintain monitoring capability while reducing local data management burden.
Solution Approach 2:
The patent introduces an external device as an intermediary for data storage and analysis. The logging device acts as a data collection intermediary that transfers data to specialized external systems, dividing the overall system complexity across multiple components.
2Loss of information
If data is transmitted frequently to external apparatus, then data availability for analysis is improved, but communication overhead and energy consumption increase
Solution Approach 1:
The patent implements periodic data transmission at specified timings rather than continuous transmission. This periodic action ensures data is available for analysis while significantly reducing communication frequency, energy consumption, and network overhead compared to continuous transmission.
3Loss of time
If all measurement data is retained locally, then data access speed is improved, but storage resource consumption increases
Solution Approach 1:
The patent extracts data from local storage and transfers it to external devices at specified timings. This extraction approach maintains local access speed for immediate operations while offloading long-term storage requirements to external systems with greater capacity.

AI summary
Provided is a logging device comprising: an acquisition unit that acquires at least one of measurement data, measured at each point in time within a specific period by a sensor provided at a specific location of a device to be monitored, or operation data, indicating the operating status of the device to be monitored; a recording unit that records, in a storage device, the data acquired by the acquisition unit; and a transmission unit that transmits the data recorded by the recording unit to an external device at a specific timing.
