Solution Overview

Problem

Current medication dispensing systems lack efficient methods for accurately identifying and managing blister packs, particularly in ensuring timely administration and handling of medications arranged in blister bags, with limited capabilities for real-time monitoring and compliance with medication plans.

Innovation Solution

A medication dispensing device equipped with sensors and a control system that uses optical, capacitive, and mechanical sensors to identify blister packs, track their position, and manage dispensing based on pre-programmed schedules, including the use of guide bags for information and the ability to signal operating states through lighting and potentially discard or return packs as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple sensor types (optical, capacitive, mechanical) are integrated to identify and track blister packs, then measurement precision and reliability are improved, but device complexity increases

Engineering Contradiction:
Improveblister pack identification accuracyVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sensor system is divided into three independent sensor types (optical, capacitive, mechanical), each performing a specific detection function. This segmentation allows each sensor to be optimized for its specific task while maintaining overall system manageability and precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple sensor types are combined into a unified sensor system that works together to detect and track blister packs. The integration of optical, capacitive, and mechanical sensors creates a comprehensive monitoring system that improves overall measurement precision through multi-modal detection.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If real-time monitoring and tracking of blister packs is implemented, then productivity and compliance are improved, but device complexity increases

Engineering Contradiction:
Improvemedication dispensing efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control system continuously receives feedback from sensors about blister pack position, presence, and status. This real-time feedback enables automated adjustments and monitoring, improving dispensing efficiency and compliance tracking without requiring complex manual intervention systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically tracks and monitors blister packs through integrated sensors and control algorithms, enabling self-service functionality. The device independently manages medication dispensing operations, reducing the need for external monitoring and improving productivity.

Inventive Principle:
Principle #25Self-service

3Loss of information

If guide bags with information are used to characterize medication, then loss of information is reduced, but device complexity increases due to additional processing requirements

Engineering Contradiction:
Improvemedication information retentionVSAvoidinformation processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Guide bags serve as intermediary information carriers between the medication packaging and the device's control system. The guide bags contain printed information that the reading device captures and processes, acting as a mediator that preserves medication information without requiring direct complex communication protocols between the medication and device.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The reading device creates a digital copy of the information printed on guide bags through optical scanning. This copying process preserves medication information in digital form for processing and tracking, reducing information loss while using standard reading device technology.

Inventive Principle:
Principle #26Copying

4Loss of time

If automated dispensing based on pre-programmed schedules is implemented, then loss of time is reduced, but device complexity increases

Engineering Contradiction:
Improvemedication administration timingVSAvoidscheduling system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

Medication dispensing schedules are pre-programmed into the control system in advance. The system automatically executes these pre-planned dispensing actions at scheduled times without requiring real-time decision-making, reducing time loss while keeping the scheduling logic manageable through advance preparation.

Inventive Principle:
Principle #10Preliminary action
