Solution Overview
Problem
Current data logging systems for physiological parameters, especially for ovulation detection, face challenges such as high costs, cumbersome devices, limited battery life, and the need for frequent device recharging or removal, which can be inconvenient and risky for implanted devices.
Innovation Solution
A system comprising a data logger with a temperature sensor, a data store, control logic for periodic storage, a transceiver for wireless data transmission, and a data reader that estimates basal body temperature by extrapolating temperature changes during sleep periods, minimizing battery drain and allowing for wireless recharging, and incorporating an accelerometer to filter movement-related data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an implantable data logger is used for continuous temperature monitoring, then measurement accuracy and automation are improved, but battery replacement requires device removal causing patient stress and medical risks
Solution Approach 1:
The system uses periodic wireless data transmission at predetermined intervals, allowing the implantable device to remain in place while automatically transmitting stored temperature data to an external receiver, eliminating the need for frequent device removal for battery replacement or data retrieval
Solution Approach 2:
An external receiver device acts as an intermediary to receive wireless transmissions from the implantable data logger, enabling data retrieval and battery recharging without requiring surgical removal of the implanted device
2Duration of action of stationary object
If an implantable data logger is used for long-term monitoring, then continuous measurement is achieved, but device size and battery capacity are limited
Solution Approach 1:
The system separates the data logging function from the power supply function, with the implantable device containing only the temperature sensor and minimal electronics, while the external receiver handles data storage and processing, enabling extended monitoring without increasing implantable device volume
Solution Approach 2:
The external receiver serves as an intermediary that provides additional processing and storage capacity without being implanted, allowing the implantable device to remain small while achieving long-term monitoring capabilities through periodic wireless data transfer
3Device complexity
If manual temperature measurements are required for ovulation detection, then measurement simplicity is maintained, but patient compliance decreases due to inconvenience and forgetfulness
Solution Approach 1:
The implantable data logger automatically performs temperature measurements and stores data without requiring patient intervention, making the system self-servicing and eliminating the need for patients to remember to take measurements, thereby significantly improving compliance
4Duration of action of moving object
If frequent device removal for battery replacement is required, then battery life is extended, but measurement continuity is interrupted
Solution Approach 1:
The system implements periodic wireless data transmission at predetermined intervals, allowing the implantable device to remain continuously implanted while automatically transmitting stored temperature data to an external receiver, ensuring uninterrupted measurement coverage
Solution Approach 2:
The temperature monitoring function continues uninterrupted as the implantable device remains in place, with automatic periodic transmissions maintaining data flow without requiring device removal, thus preserving measurement continuity
