Compact Tablet Dispenser with Vertical Cassette and Chute Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tablet dispensers are often complex, large, and prone to contamination, requiring two hands for operation and involving high manufacturing costs due to automated features.
Innovation Solution
A compact, semi-automatic tablet dispenser with vertically arranged cassettes and chutes on the front face, allowing for easy assembly and maintenance, featuring adjustable chutes that dispense tablets into cylindrical containers without the need for additional structures, and a control system for efficient dispensing based on prescription data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hopper projects directly from the front face of the tubular chamber, then the dispensing function is achieved, but the overall depth becomes large and the structure becomes complicated
Solution Approach 1:
The patent repositions the hopper from a front-face projection to a rear-side attachment on the tubular chamber. This spatial reconfiguration in the depth dimension eliminates the need for deep front projections while maintaining dispensing functionality, directly resolving the contradiction between achieving dispensing function and minimizing overall depth.
2Device complexity
If assorted solid medicines are discharged through the same chute, then the dispensing operation is simplified, but residue from prior medicines adheres to the chute causing contamination
Solution Approach 1:
The patent divides the single chute into multiple separate chutes, with each chute dedicated to a specific medicine type. This segmentation prevents cross-contamination between different medicines while maintaining simplified dispensing operations, as each chute handles only one medicine type without residue interference.
Solution Approach 2:
Each chute is assigned a specific function for a particular medicine type, creating localized functionality. This ensures that residue from one medicine does not contaminate other chutes, as each chute's interior surface is dedicated to a single medicine type, eliminating cross-contamination while keeping the system relatively simple.
3Ease of operation
If the operator uses two hands for the dispensing operation, then the dispensing control is precise, but the operation becomes less efficient
Solution Approach 1:
The patent designs the system so that the tablet container itself performs the function of positioning and triggering dispensing. The container is placed in a receptacle that automatically positions it relative to the chute, and the container's presence or insertion triggers the gate to open, eliminating the need for manual two-handed operation while maintaining precise control.
4Productivity
If a fully automatic tablet dispenser is configured to automatically supply tablet containers and dispense tablets, then the productivity is improved, but the device structure becomes complicated and manufacturing costs increase
Solution Approach 1:
The patent implements partial automation rather than full automation. The system automatically dispenses tablets when a container is placed in the receptacle, but requires manual placement of the container itself. This partial automation achieves improved productivity for the critical dispensing function while avoiding the complex structure and high costs of fully automated container supply mechanisms.

AI summary
A tablet dispenser includes a device body and a plurality of tablet cassettes disposed on one face of the device body. Each tablet cassette is capable of accommodating a plurality of types of tablets and of dispensing the tablets contained therein in a lateral direction. A plurality of chutes are in communication with the plurality of tablet cassettes. Each chute is disposed on the one face of the device body, adjacent to a corresponding tablet cassette. Each chute retains tablets dispensed from the corresponding tablet cassette and dispenses the tablets in a downward direction into a container.
