Solution Overview

Problem

Existing electronic medication storage cabinets lack efficient methods for optimizing space and guiding users in optimally loading medications, leading to challenges in managing varying medication sizes and available storage capacity.

Innovation Solution

The implementation of an electronic medication storage system that includes sensors to identify pocket positions, a mapping algorithm to generate loading sequences, and automated unlocking and verification processes to assist users in efficiently loading medications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual organization and loading of medications is performed without optimization tools, then users can load medications into the cabinet, but the process becomes time-consuming and inefficient due to difficulty in gauging space requirements and available capacity

Engineering Contradiction:
Improvemedication loading efficiencyVSAvoidtime required for organizing and loading medications
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs automatic drawer unlocking, pocket identification, and loading sequence generation without requiring manual intervention. The cabinet autonomously determines the optimal loading sequence based on medication dimensions and available space, eliminating the need for users to manually organize and gauge space requirements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical organization with an automated control system that uses sensors to detect pocket positions and a mapping algorithm to generate loading sequences. This substitution of manual mechanical operations with automated electronic control significantly reduces the time and effort required for medication loading.

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

2Quantity of substance

If the cabinet is kept close to full capacity to maximize storage utilization, then storage space is optimized, but it becomes difficult to place critical medications and access becomes slower

Engineering Contradiction:
Improvestorage capacity utilizationVSAvoidaccessibility and placement of critical medications
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The system performs preliminary analysis of the loading sequence before actual loading occurs. It identifies optimal positions for critical medications and pre-arranges the loading sequence to ensure quick access, preventing the cabinet from reaching a state where medications are difficult to place or access.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors cabinet capacity and loading status through sensors. This feedback mechanism allows the system to adjust the loading sequence in real-time, ensuring that critical medications are placed in accessible positions even as the cabinet approaches full capacity.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If reconfiguration of drawers and storage pockets is performed to accommodate varying medication sizes, then storage flexibility is improved, but the complexity of the organization process increases

Engineering Contradiction:
Improveaccommodation of varying medication sizesVSAvoidcomplexity of reconfiguration process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cabinet automatically detects the positions of storage pockets using sensors and independently determines the optimal reconfiguration sequence. This eliminates the need for users to manually track and reorganize pockets, reducing the perceived complexity while maintaining high adaptability to different medication sizes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mapping algorithm serves multiple functions: it identifies pocket positions, calculates optimal loading sequences, and adapts to various medication dimensions. This single universal system handles diverse reconfiguration scenarios without requiring separate complex mechanisms for each case.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An electronic medication storage cabinet includes a plurality of drawers configured with a plurality of sensors arranged to identify a positioning of storage pockets within the drawers. Upon receiving an indication of a new medicine container to be loaded in the cabinet, a sequence of steps to load the medicine container into the cabinet is generated based on a mapping algorithm. A first step is displayed on a display associated with the cabinet, and a determination is made as to whether the first step is associated with one of the plurality of drawers. In response to determining that the first step is associated with one of the plurality of drawers, the drawer is automatically unlocked. In response to determining that the first step is successfully completed, a determination of whether execution of any additional steps is pending and indicated on the display.
