Biological Sample Measurement Device Impact Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biological sample measuring apparatuses face low measurement accuracy due to impacts applied to the blood glucose level sensor before the completion of the measurement process, which can cause blood to fail in reaching the reaction reagent smoothly, leading to inaccurate results.
Innovation Solution
Incorporating an acceleration sensor in the biological sample measuring apparatus to detect excessive impacts during the measurement process, displaying an error message when the impact exceeds a predetermined value, thereby preventing the display of inadequate measured values and improving measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blood is spotted on the sensor and measurement is performed, then measurement function is achieved, but measurement accuracy deteriorates when impact is applied during the process
Solution Approach 1:
The acceleration sensor detects impact before it can affect the measurement result. By monitoring for impact events during the blood spotting and measurement process, the system can identify and flag measurements that were taken under compromised conditions, preventing inaccurate results from being displayed or used.
Solution Approach 2:
The system continuously monitors acceleration during the measurement process and provides feedback about impact events. When impact exceeding a threshold is detected, the system responds by indicating measurement invalidity, creating a closed-loop system that ensures measurement quality through real-time monitoring and correction.
2Reliability
If acceleration sensor is added to detect impact, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The acceleration sensor serves multiple functions: it detects impact during measurement, validates measurement conditions, and triggers appropriate system responses. This multi-functionality justifies the addition of the sensor by providing comprehensive protection against measurement errors through a single component rather than requiring multiple specialized sensors or systems.
