Sensor Device Data Storage for Incontinence Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring incontinence-related data from absorbent products lack efficient data storage and transmission capabilities, particularly in situations where a stable communication link is not established, leading to incomplete or lost data and inefficient care planning.
Innovation Solution
A system with intermediate storage units in both the sensor device and a database arrangement, allowing raw measurement data to be stored and transmitted later when a secure link is established, along with a transceiver unit for wireless communication via a conventional telephone network, and a database structure for secure and reliable data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If sensor device transmits data continuously to server, then data availability is improved, but energy consumption increases and reliability decreases in areas with poor network coverage
Solution Approach 1:
The sensor device performs preliminary actions by storing measurement data locally in its memory unit before transmission is attempted. This ensures data is preserved and ready for transmission when network conditions permit, preventing data loss in areas with poor coverage while avoiding continuous transmission attempts that would waste energy and reduce reliability.
Solution Approach 2:
The memory unit in the sensor device acts as an intermediary between data generation and data transmission. It temporarily holds measurement data, allowing the device to decouple the sensing function from the transmission function, thereby maintaining data availability independent of network conditions while conserving energy.
2Loss of information
If sensor device stores measurement data locally, then data loss is prevented, but device complexity increases
Solution Approach 1:
The memory unit is merged with the sensor device, combining the sensing functionality with local data storage capability in a single integrated unit. This eliminates the need for separate storage infrastructure, reducing overall system complexity while ensuring data is preserved locally before transmission.
3Loss of information
If sensor device enters pending state before shutting off, then data transmission opportunity is maximized, but energy consumption increases
Solution Approach 1:
The sensor device employs periodic action by entering a pending state for a predetermined time period after removal from the absorbent product, during which it attempts to transmit stored measurement data. This time-limited periodic attempt balances the need for complete data transmission with energy conservation, as the device shuts off after the pending period expires if transmission is not completed.

AI summary
The invention relates to a process for collecting and storing data related to a condition of an absorbent product (3), comprising the steps of: receiving, in a server unit (12), measurement data related to said condition; storing said measurement data in a first database (13); and adapting said measurement data to a format in which it can be utilized by at least one application program configured for analyzing said condition. According to the invention, the process comprises: storing the adapted measurement data in a second database (14); and providing access to said second database (14) from at least one application program (16) arranged for analyzing said measurement data. The invention also relates to an arrangement for collecting and storing incontinence-related data.
