Low-Profile X-Y Table for Accurate Multi-Format Pill Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for automatically filling prescriptions lack flexibility and accuracy, particularly in filling vials and blister packs from multiple canisters, as they are limited to dispensing a single type of pill or require multiple machines for different packaging formats.
Innovation Solution
A pill dispensing apparatus with a low-profile X-Y table and interchangeable platens that can move in both X and Y directions, allowing for precise placement and filling of pills into various vial or blister pack configurations, using identification devices like RFID or bar codes to manage pill types and quantities across multiple canisters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual labor is used for dispensing pills into vials or blister packs, then flexibility in handling different package types is maintained, but accuracy and productivity deteriorate due to human error and labor intensity
Solution Approach 1:
The system uses RFID readers and barcode scanners to automatically identify platens and canisters, with the control system autonomously determining dispensing parameters and coordinating the X-Y table movement, eliminating the need for manual intervention in the dispensing process while maintaining high accuracy
Solution Approach 2:
The patent replaces manual mechanical operations with an automated electromechanical system featuring an X-Y table with motors for precise positioning, automated platen identification through RFID/barcode reading, and computer-controlled coordination of all components to achieve accurate pill dispensing without human labor
2Adaptability or versatility
If fixed-type dispensing equipment is used, then device complexity is reduced, but adaptability deteriorates as it cannot handle multiple package types and medication varieties
Solution Approach 1:
The system employs interchangeable platens that can be configured for different package types (vials, blister packs, bottles), with each platen identifiable through RFID or barcode tags. The control system automatically adapts to the selected platen type, enabling a single device to handle multiple package configurations and medication types without requiring separate specialized equipment for each
3Productivity
If automated dispensing systems are implemented, then productivity increases, but manufacturing precision deteriorates due to positioning errors in placing pills into correct locations
Solution Approach 1:
The system incorporates RFID readers and barcode scanners that automatically identify the selected platen and canister, providing feedback to the control system. This feedback enables the controller to accurately determine the correct positioning coordinates for pill dispensing, ensuring precise placement into the intended locations while maintaining high dispensing speed through automated coordination
4Manufacturing precision
If simple X-Y table mechanisms are used, then device complexity is reduced, but manufacturing precision deteriorates due to inability to achieve accurate positioning for multiple package types
Solution Approach 1:
The X-Y table employs motorized drives with controllable speed and position, allowing dynamic adjustment of movement parameters based on the selected platen type and package configuration. This dynamic control enables precise positioning for different package types while the system adapts its complexity only when needed, rather than requiring maximum complexity for all operations
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
Enables accurate and flexible filling of prescriptions into vials or blister packs from multiple canisters, reducing errors and increasing efficiency by allowing a single machine to handle various pill types and packaging formats, while maintaining precise control over pill distribution.
Implementation Method 1
An X-drive motor is mounted to the platform and interfaced to an X-drive gear. An X-drive linear gear is slideably held within an X-direction slot of the platform and is in communication with the X-drive gear such that rotation of the X-drive gear results in linear movement of the X-drive linear gear
Implementation Method 2
A Y-drive motor is also mounted to the platform and interfaced to a Y-drive gear. A Y-drive linear gear is slideably held within a Y-direction slot of the platform and is in communication with the Y-drive gear such that rotation of the Y-drive gear results in linear movement of the Y-drive linear gear
Implementation Method 3
An X-plane truck is attached to the X-drive linear gear and has at least one X-plane bearing that is slideably held in the X-truck trough
Implementation Method 4
A Y-plane truck is attached to the Y-drive linear gear and has at least one Y-plane bearing that is slideably held in the Y-truck trough

AI summary
An X-Y table includes a platform and a frame which has an X and Y-truck trough. An X-drive motor interfaced to an X-drive gear. A Y-drive motor interfaced to a Y-drive gear. Both motors are affixed to the platform. An X-drive linear gear slideably held within an X-direction slot communicates with the X-drive gear whereas rotation of the X-drive gear results in linear movement of the X-drive linear gear. A Y-drive linear gear, slideably held within a Y-direction slot communicates with the Y-drive gear. An X-plane truck attached to the X-drive linear gear is slideably held in the X-truck trough. A Y-plane truck attached to the Y-drive linear gear is slideably held in the Y-truck trough. The frame moves in an X-direction responsive to rotation of the X-drive motor and in a Y-direction responsive to rotation of the Y-drive motor.
