Solution Overview

Problem

Traditional methods for dispensing bottled medication in hospitals and pharmacies are inefficient, error-prone, and labor-intensive, and existing automatic dispensing devices are not well-suited for bottled medications due to jamming issues and increased costs.

Innovation Solution

A baffle blocking type medication dispensing unit with a medication container angled at greater than 10° and a rotary dispensing baffle mechanism that ensures smooth dispensing by blocking and opening to prevent jamming, using an elastic strip to secure the baffle in place, allowing for reliable and efficient dispensing of medications in a single row.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple rows and columns of bottled injections are placed in the medication container, then the medication storage capacity is increased, but the blocking is prone to happen during the process of adjacent sawteeth of sorting turntable driving the bottled injection, resulting in unsmooth medication dispensing

Engineering Contradiction:
Improvemedication storage capacityVSAvoiddispensing smoothness
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent divides the medication container into multiple single-row compartments, each handling one bottle at a time. This segmentation prevents multiple bottles from interfering with each other during dispensing, eliminating blocking issues while maintaining adequate storage capacity through vertical stacking of containers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from horizontal multi-row storage to vertical stacking of single-row containers. By utilizing the vertical dimension, the system maintains high storage capacity without the horizontal crowding that causes blocking during dispensing operations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If a detection device is added to detect vacancy in the placement position, then the dispensing accuracy is improved, but the cost is increased

Engineering Contradiction:
Improvevacancy detection accuracyVSAvoiddetection device cost
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses the physical presence or absence of bottles themselves to indicate vacancy, rather than adding separate detection devices. The single-row configuration with gravity-fed dispensing makes vacancy detection inherent to the mechanical operation, eliminating the need for additional sensors or detection systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent employs simple, low-cost mechanical indicators such as position markers or visual indicators that can be easily replaced or reset, avoiding expensive electronic detection systems while maintaining adequate vacancy detection capability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of operation

If the medication container is tilted at an angle greater than 10°, then the medication discharging end is lower than its rear end, but the structure complexity is increased

Engineering Contradiction:
Improvemedication discharge efficiencyVSAvoidcontainer positioning structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent designs the container and dispensing mechanism as an integrated unit where the tilt angle is built into the structure, creating a natural gravity flow path. This eliminates the need for complex adjustable positioning mechanisms while maintaining the beneficial gravity-assisted dispensing effect.

Inventive Principle:
Principle #12Equipotentiality

Solution Approach 2:

The patent optimizes the tilt angle parameter to greater than 10° to ensure proper gravity flow for medication discharge. This specific parameter change creates sufficient gravitational force to move bottles smoothly without requiring additional mechanical assistance, balancing discharge efficiency with structural simplicity.

Inventive Principle:
Principle #35Parameter changes
