Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pill dispensing systems face challenges in accurately recording the delivery and taking of medication without increasing system complexity, particularly in ensuring patients comply with their medication regimens effectively.
Innovation Solution
A monitoring device with a detector and controller system that distinguishes between the covering of a pill outlet region by a user and the passage of a pill using a light source and detector, providing a low-cost and compact solution for monitoring pill dispensing and taking, which can be integrated with pill dispensing stations or used as a portable device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a detector is used to monitor pill dispensing, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The detector serves multiple functions: it detects both the passage of pills along the exit channel and the covering of the outlet region by the user. This multi-functionality improves measurement precision for compliance monitoring while avoiding the need for additional separate sensors, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent combines the pill passage detection and user interaction detection into a single detector system. By merging these two detection functions into one component, the system achieves high measurement precision for both events without proportionally increasing device complexity.
2Measurement precision
If multiple sensors are added to distinguish user interaction from pill passage, then measurement precision is improved, but device complexity increases
Solution Approach 1:
A single detector is designed to perform multiple detection tasks: identifying pill passage through the exit channel and detecting when the outlet region is covered by the user. This multi-functional approach achieves high compliance data accuracy without requiring multiple separate sensors, thus avoiding increased device complexity.
Solution Approach 2:
The detector distinguishes between pill passage and user interaction by analyzing changes in detection signal parameters (such as signal duration, amplitude, or temporal patterns). This parameter-based differentiation allows one sensor to provide precise compliance data without needing multiple physical components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides more accurate compliance data by differentiating between user interaction and pill passage, enabling personalized medication management and alerting caregivers to non-compliance, thus improving patient adherence to medication schedules.
Implementation Method 1
The detector for example comprises a light source and a light detector. A light source and detector provides a low-cost sensing approach. The light detector is for example located adjacent the light source and is for detecting reflected light.
Data Source
AI summary
A device is provided for monitoring the delivery and taking of medication pills by detecting both the passage of a pill and the covering of a pill outlet region, which is indicative of an active operation of the user to remove the pill from the pill outlet region. In this way, pill delivery can be monitored as well as an indication of actual pill taking.
