Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in ensuring appropriate temperature management for medicines, particularly those for rare diseases, which are expensive and have low demand, making it difficult to verify their storage conditions, leading to barriers in their utilization and potential quality deterioration.
Innovation Solution
A cold storage box equipped with an RF tag and temperature sensor for each stored object, a control part that communicates with the RF tag at appropriate intervals, and a management system that records and transmits temperature history, alerts for temperature abnormalities, and reduces power consumption by adjusting communication based on lid state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous communication between control part and RF tag is implemented, then temperature monitoring reliability is improved, but power consumption increases
Solution Approach 1:
The control part communicates with the RF tag at predetermined time intervals rather than continuously. The communication frequency is adjusted based on the lid state: higher frequency when lid is closed (storage mode) and lower frequency when lid is open (access mode), thereby reducing overall power consumption while maintaining monitoring reliability
Solution Approach 2:
The system uses lid state detection as feedback to dynamically adjust communication frequency. When the lid is detected to be open, communication frequency is reduced to conserve battery power of the RF tag. When lid is closed, communication frequency increases to ensure accurate temperature monitoring, creating an adaptive power management strategy
2Measurement precision
If temperature monitoring frequency is increased, then temperature management accuracy is improved, but power consumption of RF tag increases
Solution Approach 1:
Temperature monitoring is performed at predetermined time intervals rather than continuously. The monitoring frequency is dynamically adjusted based on lid state, providing high accuracy when needed (lid closed) while conserving energy during access operations (lid open)
Solution Approach 2:
The system transitions from static continuous monitoring to dynamic adaptive monitoring. Communication frequency changes based on operational context (lid state), optimizing the balance between measurement precision and power consumption for the RF tag battery
3Measurement precision
If communication is performed at high frequency, then data accuracy is improved, but device complexity increases
Solution Approach 1:
The lid state detection mechanism automatically triggers appropriate communication frequency adjustments without requiring external intervention or complex control algorithms. The system self-regulates based on its own operational state, simplifying the control architecture while maintaining data accuracy
