Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing analysis systems for blood glucose monitoring, particularly those used by visually impaired or blind individuals, face challenges in ensuring accurate acoustic output of information, which is critical for user safety and precise insulin dosing, as incorrect acoustic signals can lead to misinterpretation of vital health data.
Innovation Solution
Incorporating an acoustic signal transmitter that emits a test signal to verify its functionality, allowing users to recognize correct or incorrect acoustic output, and using a control unit to manage this signal, which can be triggered by inserting a test element or initiating the analysis system, with customizable tone sequences and volumes to differentiate normal operation from malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an acoustic signal generator is used to output information in an analysis system, then information can be conveyed to visually impaired users, but the reliability of the acoustic output cannot be verified
Solution Approach 1:
The system performs a preliminary self-diagnosis by emitting a test tone before providing acoustic information output. This preliminary action verifies the acoustic signal generator's functionality in advance, ensuring reliability before the actual information conveyance occurs.
Solution Approach 2:
The system incorporates a feedback mechanism where the acoustic signal generator emits a test tone and the system monitors the output to determine functionality. This feedback loop allows the system to verify its own operational status and adjust or alert the user accordingly.
2Device complexity
If no functionality check is performed, then the system remains simple, but incorrect acoustic signals may lead to misinterpretation of health data
Solution Approach 1:
The system emits a test tone as a preliminary action before providing health information through acoustic signals. This simple preliminary check prevents the harmful effect of misinterpretation by ensuring the acoustic output is functional, without significantly increasing system complexity.
3Productivity
If the acoustic signal generator is not tested, then the analysis system operates continuously, but malfunctions may go undetected causing unnecessary testing or sample waste
Solution Approach 1:
The system performs a preliminary functionality check by emitting a test tone before conducting actual sample analysis. This prevents malfunctions from going undetected, thereby avoiding unnecessary testing and sample waste while maintaining continuous operational capability.
Solution Approach 2:
The system uses feedback from the test tone emission to determine whether the acoustic signal generator is functioning correctly. If a malfunction is detected through this feedback mechanism, the system can alert the user or prevent further operations that would result in sample waste.
