Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The power consumption of biomolecule detection devices, particularly those using decomposition reactions for power generation, is high due to the energy requirements of real-time radio signal transmission, which can exceed the power generated by the internal power generation unit.
Innovation Solution
A measuring system that utilizes a near-field wireless communication method to transmit information about the power generation amount from a measuring device attached to a living body to a container device, employing a power generation unit that converts biomolecules into electromotive force, oscillation signals, and a counter circuit to store and transmit data using minimal power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If real-time radio signal transmission is implemented in the measuring device, then information transmission capability is improved, but power consumption increases beyond the power generation capacity
Solution Approach 1:
The patent implements periodic action by transmitting radio signals only at specific intervals (e.g., when the measuring device is removed from the container or at predetermined time points) rather than continuously. The transmission control unit activates the radio signal transmission unit only during these periodic opportunities, significantly reducing overall power consumption while still maintaining information transmission capability.
Solution Approach 2:
The patent applies preliminary action by storing measurement results in the measuring device before transmission occurs. The measurement unit continuously accumulates data locally, and the transmission control unit prepares the data for transmission in advance during opportunistic moments (such as when removed from the container), eliminating the need for continuous real-time transmission.
2Measurement precision
If continuous measurement and transmission of power generation amount is performed, then measurement precision is improved, but power consumption increases
Solution Approach 1:
The measurement and transmission operations are performed periodically rather than continuously. The measurement unit measures the power generation amount at discrete intervals, and the transmission control unit transmits accumulated measurement results only at predetermined opportunities (such as when removed from the container), reducing power consumption while maintaining adequate measurement precision through sufficient sampling frequency.
Solution Approach 2:
The measurement unit performs preliminary measurements and accumulates multiple power generation amount data points before transmission. This allows the device to maintain precise measurement capability by continuously monitoring locally, while deferring the energy-intensive transmission operation to periodic opportunities when power consumption can be minimized.
