Solution Overview

Problem

Conventional automatic medicine packing machines are limited by the space constraint of medicine cassettes, leading to inefficiencies in medicine packing operations, and manual refilling is cumbersome and prone to errors, risking medical accidents.

Innovation Solution

An automatic medicine packing machine equipped with a medicine cassette replacement system using a transfer robot to swap empty cassettes with new ones, maintaining the same orientation and facilitating faster, larger-scale packing operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual refilling of medicine cassettes is performed, then the pharmacist can refill medicines, but the operation becomes cumbersome and error-prone

Engineering Contradiction:
Improvemedicine refilling operationVSAvoidmedicine packing accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables self-service automation where the medicine packing machine automatically detects empty cassettes and replaces them with full cassettes from the storage part, eliminating the need for manual pharmacist intervention in the refilling process

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical operation of removing and installing cassettes is replaced by an automated robot arm that performs the cassette replacement operation, substituting human manual labor with automated mechanical systems

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Area of stationary object

If medicine cassettes are placed in limited space on the main body, then the machine structure is compact, but the number of medicines that can be supplied is limited

Engineering Contradiction:
Improvemain body spaceVSAvoidmedicine supply capacity
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The system is divided into two separate functional parts: the main body with mounting part for active cassette usage, and a separate storage part for reserve cassettes. This segmentation allows the machine to maintain a compact main body while having access to additional cassettes in the storage part

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The robot arm acts as an intermediary between the storage part and mounting part, transferring cassettes from the storage part to the mounting part when needed, enabling the system to overcome the space limitation of the main body

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If cassettes are manually refilled by pharmacists, then refilling can be performed, but the process is time-consuming and reduces packing efficiency

Engineering Contradiction:
Improverefilling capabilityVSAvoidmedicine packing efficiency
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The system performs automatic self-service cassette replacement where the robot arm detects empty cassettes in the mounting part and replaces them with full cassettes from the storage part, maintaining continuous packing operation without pharmacist intervention

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Full cassettes are pre-stored in the storage part, ready for immediate replacement when mounting part cassettes become empty, ensuring continuous operation without interruption to packing efficiency

Inventive Principle:
Principle #10Preliminary action
