Solution Overview

Problem

Existing automated dispensers face challenges in loading and stabilizing carts with fixed wheels, making it difficult to insert them into enclosures safely and efficiently, especially in populated areas like hospitals.

Innovation Solution

The design incorporates a pivotable wheel support mechanism that allows carts with fixed wheels to be easily loaded into dispensers by pivoting the wheels from an external position to an internal position, facilitating stable and safe movement and alignment with the dispenser's interior.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If carts with non-swiveled (fixed) wheels are used for transporting cartridges, then stability during transport is improved, but difficulty in inserting the cart into the dispenser increases

Engineering Contradiction:
Improvetransport stabilityVSAvoidinsertion difficulty
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The wheel support mechanism is designed to be movable between extended and retracted positions, allowing it to dynamically adapt to different operational phases: extended during insertion to guide fixed wheels, and retracted during transport to maintain cart stability. This dynamic adjustment resolves the contradiction between insertion ease and transport stability.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If carts with only swiveled wheels are used for easy insertion, then ease of operation is improved, but transport safety and stability deteriorate

Engineering Contradiction:
Improveinsertion easeVSAvoidtransport safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The wheel support mechanism acts as an intermediary device that temporarily interacts with the cart's wheels during insertion. It provides guidance and support for fixed wheels without requiring the cart to change its wheel configuration, thereby maintaining transport safety while facilitating easy insertion.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If a wheel support mechanism is added to facilitate cart insertion, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improvecart loading easeVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wheel support mechanism is designed to be self-actuating through spring-loaded components that automatically extend to guide wheels during insertion and retract when not needed. This self-service capability eliminates the need for complex motorized controls or manual operation, reducing overall system complexity while maintaining ease of use.

Inventive Principle:
Principle #25Self-service

AI summary

A dispenser having an interior portion that is dimensioned for receiving a wheeled cart that is configured for storing items to be dispensed from the dispenser. The cart may, for example, be supported by at least two non-swiveled wheels disposed adjacent a first end of the cart and at least one swiveled wheel disposed adjacent a second end of the cart. In particular embodiments, the dispenser includes a pivotable wheel support that is adapted for: (A) supporting the cart's non-swiveled wheels; and (B) while supporting these non-swiveled wheels in respective, substantially fixed positions relative to the pivotable wheel support, pivoting from: (1) a first position in which the cart is positioned outside the dispenser; to (2) a second position in which the cart is positioned within the dispenser's interior. This may assist in loading the cart into the dispenser.
