Medication Support Device Skipping Abnormal Dispensing Processes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medication support devices face challenges in efficiently dispensing medicines to patients while ensuring accuracy and preventing medication errors, particularly in identifying and addressing abnormalities during the dispensing process.
Innovation Solution
A medication support device that includes a container for storing medicine packages, a pickup device to retrieve packages, a conveyor for transporting them, a medicine dispenser with a prescribed position for dispensing packages, a medication-related information reader for identifying patient information and medication times, and processing circuitry to control the dispensing operation based on read information, allowing the system to skip abnormal processes and continue the dispensing operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system performs strict verification of medication-related information for every medicine package, then medication accuracy is improved, but dispensing speed and operational efficiency deteriorate
Solution Approach 1:
The system implements a skip mechanism that allows the dispensing operation to bypass processes with abnormalities. When the verification unit detects an abnormality in medication-related information, the control unit enables the dispensing to continue by skipping that particular verification step, rather than halting the entire process. This resolves the contradiction by maintaining overall dispensing speed while still performing verification where normal.
Solution Approach 2:
The system performs verification selectively rather than uniformly for all medicine packages. The verification unit focuses on detecting abnormalities in medication-related information, and the control unit applies partial verification - complete verification for normal cases and skipped verification for abnormal cases. This partial action approach maintains accuracy for critical cases while improving overall dispensing efficiency.
2Reliability
If the system halts dispensing operation when an abnormality is detected, then medication safety is improved, but operational continuity and efficiency deteriorate
Solution Approach 1:
The control unit is configured to skip processes with abnormalities and continue the dispensing operation. When the verification unit detects abnormal medication-related information, the system skips that specific abnormal process rather than halting the entire dispensing operation. This allows the system to maintain operational continuity while still identifying and flagging safety concerns for later review.
Solution Approach 2:
The system implements a feedback mechanism where the verification unit continuously monitors medication-related information and provides feedback to the control unit. When abnormalities are detected, the feedback triggers a skip action for that specific process while maintaining overall operational flow. This feedback loop ensures safety monitoring without causing complete operational interruptions.
3Reliability
If the system verifies medication-related information for every package, then medication errors are reduced, but processing time and operational complexity increase
Solution Approach 1:
The system skips verification processes for packages with detected abnormalities rather than performing exhaustive verification on every single package. The verification unit identifies abnormal medication-related information, and the control unit skips further processing for those specific cases, reducing overall processing time while maintaining error prevention for normal packages.
Solution Approach 2:
The verification system applies partial verification - performing complete medication-related information verification only when necessary (when abnormalities are detected), and skipping verification for normal packages. This selective partial action reduces processing time for the majority of normal packages while maintaining thorough verification where needed to prevent errors.

AI summary
A medication support device includes a container to store a medicine package in which a plurality of medicines are packed, a pickup device to pick up the medicine package from the container, a conveyor to convey the medicine package picked up by the pickup device, a medicine dispenser including a prescribed position to which the medicine package conveyed by the conveyor is dispensed, a medication-related information reader to read medication-related information including at least a name of a patient who takes medicines and a time of medication, and processing circuitry to control a medicine dispensing operation in which the medicine package picked up from the container is dispensed to the medicine dispenser, based on the medication-related information read by the medication-related information reader, and skip a process with an abnormality and make the medicine dispensing operation continue after the medicine dispensing operation starts.
