Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glucose regulation apparatuses for blood glucose management lack accuracy and safety due to reliance on a single control mechanism and limited consideration of user activity and responsiveness, potentially leading to inadequate dosing of glucose-influencing substances.
Innovation Solution
Incorporating a second control means and additional sensors, such as accelerometers, heart rate sensors, and pH sensors, to independently determine the amount of substances influencing blood glucose levels, taking into account physical and mental activity, and using algorithms to adjust dosing based on multiple data inputs for improved accuracy and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single control means is used to determine the amount of substance influencing blood glucose levels, then the device complexity is reduced, but the reliability and accuracy of glucose regulation deteriorates
Solution Approach 1:
The control system is divided into two independent control means (first control means and second control means), each independently determining the amount of substance to be administered based on glucose sensor data. This segmentation allows cross-verification of dosing decisions, improving reliability while maintaining manageable complexity through modular design.
Solution Approach 2:
The second control means provides a feedback mechanism that independently verifies the dosing decision made by the first control means. Both control means receive data from the glucose sensor and independently calculate the required substance amount, creating a feedback loop that enhances dosing accuracy without requiring overly complex integrated control logic.
2Adaptability or versatility
If additional sensors (accelerometer, heart rate sensor, pH sensor) are incorporated to monitor user activity and responsiveness, then the adaptability and accuracy of dosing is improved, but the device complexity and cost increases
Solution Approach 1:
The control means is designed to process data from multiple sensor types (glucose sensor, accelerometer, heart rate sensor, pH sensor) through a unified algorithm that adapts dosing decisions based on any combination of these inputs. This multi-functionality approach allows the system to leverage various sensor data sources without requiring separate processing pathways for each sensor type, managing complexity while enhancing adaptability.
Solution Approach 2:
The system dynamically adjusts dosing parameters based on changes in physiological parameters detected by the sensors. The algorithm modifies the amount of substance to be administered according to real-time data from accelerometers (activity level), heart rate sensors (cardiovascular response), and pH sensors (metabolic state), allowing flexible adaptation without hardcoding specific response rules for each sensor.
3Manufacturing precision
If the control system independently determines dosing without considering user activity and responsiveness, then the device complexity is reduced, but the manufacturing precision and safety of dosing deteriorates
Solution Approach 1:
The system performs preliminary assessments of user state by continuously monitoring activity levels, heart rate, and pH levels before making dosing decisions. The control algorithm pre-evaluates multiple physiological parameters and prepares adjusted dosing recommendations based on predicted user responsiveness, enabling more precise dosing without requiring complex real-time calculations at the moment of administration.
