Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated packaging systems for oral solid pharmaceuticals lack the capability to verify with absolute confidence that the medications are precisely placed according to patient prescription data within a single system, particularly in blister carded packaging, often requiring manual review and prone to errors and delays.
Innovation Solution
The implementation of robotic pick-and-place automation combined with various sensors, including imaging and optical sensing units, to verify the accurate placement of oral solid pharmaceuticals into package locations based on patient prescription data, ensuring precise matching and preventing erroneous transfers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated packaging systems are used to place oral solid pharmaceuticals into packages, then packaging speed and efficiency are improved, but the ability to verify precise placement according to patient prescription data deteriorates
Solution Approach 1:
The system incorporates sensors that detect the presence and characteristics of pharmaceutical products in package cavities, providing real-time feedback to the controller. The controller compares sensor data with prescription requirements and adjusts the pick-and-place operation accordingly, enabling automatic verification that maintains both speed and accuracy.
Solution Approach 2:
Manual verification by technicians is replaced with automated optical or electromagnetic sensors that detect pharmaceutical product characteristics. This substitution enables continuous automatic verification without sacrificing packaging speed, as sensors can rapidly detect multiple cavities simultaneously.
2Reliability
If manual review by trained technicians is performed to verify packaged pharmaceuticals, then verification accuracy is improved, but time consumption and operational complexity increase
Solution Approach 1:
The packaging system performs self-verification through integrated sensors and controllers that automatically check whether pharmaceutical products are correctly placed in package cavities according to prescription data. This eliminates the need for separate manual review steps, maintaining high accuracy while reducing time loss.
Solution Approach 2:
The verification function is merged with the packaging operation itself. Sensors are integrated into the pick-and-place system, allowing verification to occur during the packaging process rather than as a separate post-packaging step, thereby eliminating additional time consumption.
3Reliability
If multiple independent verifications are implemented within a single automation system, then reliability is improved, but device complexity increases
Solution Approach 1:
The controller serves multiple functions: it manages the pick-and-place operation, processes sensor data, compares product characteristics with prescription requirements, and controls verification logic. This multi-functionality reduces overall system complexity while maintaining multiple verification points through a single integrated control unit.

Implementation Method 1
an imaging unit associated with the pick-and-place device verifies that the oral solid pharmaceutical product presented by the tray or canister matches the size and shape and/or color of an expected oral solid pharmaceutical product
Implementation Method 2
a variety of sensors are used in order to verify that the oral solid pharmaceuticals have been properly placed in the desired oral solid pharmaceutical package locations
Data Source
AI summary
Robotic pick-and-place automation is used to transfer oral solid pharmaceuticals from moveable trays or canisters. Sensors are used to verify that the pharmaceuticals have been properly placed in the desired pharmaceutical locations precisely according to the patient prescription data. A pharmacist places pharmaceutical products within dispensing trays or canisters to present the pharmaceutical products for picking and placing via the robotic pick-and-place machinery. Once the canister or tray is located adjacent the pick-and-place device, a sensor or imaging unit associated with the pick-and-place device verifies that the pharmaceutical product, the size, shape, and/or color of an expected pharmaceutical product that is to be placed within the packaging material in accordance with patient prescription data stored by a computer associated with the system. Sensors verify that each individual pharmaceutical specified by a patient prescription have been deposited into each specified location strictly in accordance with the patient prescription data.
