Adjustable Inlet Wall for Pharmaceutical Singulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated pharmacy systems for dispensing pharmaceuticals lack efficient mechanisms for adjusting the size of the inlet to singulate pharmaceutical articles, leading to potential dispensing errors and inefficiencies.
Innovation Solution
An apparatus with a housing assembly and an adjustment system that includes a moveable second inlet wall relative to a first inlet wall, allowing for tactile and/or audible feedback to operators, enabling precise adjustment of the inlet size to singulate pharmaceutical articles passing through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the inlet size is fixed, then the device structure is simple, but the ability to singulate pharmaceutical articles of different sizes is poor
Solution Approach 1:
The patent implements a movable second inlet wall that can be adjusted relative to the first inlet wall, transforming the fixed inlet structure into a dynamic one. This allows the inlet size to be changed to accommodate different sizes of pharmaceutical articles, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The inlet structure is divided into two separate walls (first inlet wall and second inlet wall) that can move independently. This segmentation allows one wall to remain fixed while the other is adjusted, providing adaptability without requiring complete structural redesign.
2Measurement precision
If the inlet size is adjusted without feedback mechanism, then the device complexity is low, but the adjustment precision is poor
Solution Approach 1:
The patent incorporates an operator feedback mechanism that provides tactile and/or audible feedback during adjustment. This feedback system allows operators to precisely determine when the inlet reaches the desired size, significantly improving adjustment precision while adding only moderate complexity through simple feedback components.
3Productivity
If automated dispensing is implemented, then productivity is improved, but dispensing errors may occur due to improper inlet size
Solution Approach 1:
The system requires inlet size adjustment to be completed before automated dispensing begins. This preliminary action ensures that the inlet is properly configured for the specific pharmaceutical articles, preventing dispensing errors while maintaining automated efficiency.
Solution Approach 2:
The feedback mechanism provides confirmation that the inlet has reached the correct size, serving as a verification step before dispensing. This reduces the risk of dispensing errors by ensuring proper configuration, thereby improving reliability without significantly impacting productivity.

AI summary
An apparatus for dispensing pharmaceutical articles includes a housing assembly and an adjustment system. The housing assembly includes a first inlet wall and a second inlet wall that is moveable relative to the first inlet wall. The housing assembly defines a hopper chamber that houses pharmaceutical articles, and a dispensing channel fluidly connected to the hopper chamber. The dispensing channel has an inlet and an outlet and defines a flow path. The inlet is defined at least in part by the first and second inlet walls. The adjustment system is operable to adjust the position of the second inlet wall relative to the first inlet wall to adjust the size of the inlet to singulate the pharmaceutical articles passing through the inlet. The adjustment system includes an input mechanism and an operator feedback mechanism. The input mechanism is selectively operable by an operator to selectively move the second inlet wall relative to the first inlet wall. The operator feedback mechanism provides tactile and/or audible feedback to the operator responsive to operation of the input mechanism by the operator to indicate prescribed increments of movement of the second inlet wall relative to the first inlet wall.
