Low-Profile X-Y Table With Non-Overlapping Drive Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems for medicine, particularly those that fill vials and blister packs, lack flexibility and often result in errors due to the need for overlapping X-Y drive mechanisms, leading to thicker tables and increased complexity.
Innovation Solution
A low-profile X-Y table design that eliminates the need for overlapping X-Y drive mechanisms by using a platform and frame with separate X and Y drive motors/actuators, allowing for independent movement in both directions without increasing thickness, enabling efficient and flexible dispensing of pills into various container configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If overlapping drive mechanisms are used to move the frame in X and Y directions, then the dispensing system can achieve multi-directional movement, but the profile height of the X-Y table increases
Solution Approach 1:
The patent repositions the Y-axis drive mechanism from a vertical orientation (overlapping with X-axis) to a horizontal orientation along the Y-trough. This dimensional reconfiguration allows both X and Y drive mechanisms to operate in the same plane without vertical overlap, achieving low-profile construction while maintaining full bi-directional movement capability
2Adaptability or versatility
If multiple machines are used for filling different packaging types, then various packaging configurations can be handled, but the system complexity and error risk increase
Solution Approach 1:
The patent designs a universal X-Y table platform with interchangeable platens that can accommodate different packaging types (vials, blister packs, bottles). The standardized frame and drive mechanisms serve multiple functions by supporting various platen configurations, eliminating the need for separate dedicated machines for each packaging type and thereby reducing overall system complexity

AI summary
An X-Y table includes a platform and a frame which has an X and Y-truck trough. An X-plane truck is slideably held in the X-truck trough. A Y-plane truck is slideably held in the Y-truck trough. As the motor/actuator with drive mechanisms moves the frame in an X-direction the Y-truck moves through the Y-trough and as the motor/actuator with drive mechanisms moves the frame in a Y-direction the X-truck moves through the X-trough, thereby moving the frame in both the X-direction and the Y-direction.
