Solution Overview

Problem

Existing devices for storing and issuing objects, such as vending machines and key dispensers, face inefficiencies in transferring items from a storage compartment to an output due to reliance on motorized transport, which is time-consuming and requires complex maintenance.

Innovation Solution

The use of plug-in tags and inclined plug-in shafts with electromagnetically actuated bolts allows for gravity-assisted transfer, eliminating the need for continuous power and enabling fast, reliable, and secure object release and return, with contactless identification for secure access and tracking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If motorized transport devices are used to transfer objects from storage compartment to output shaft, then the transfer can be automated, but the process becomes time-consuming and requires complex maintenance

Engineering Contradiction:
Improveautomation of object transferVSAvoidtransfer time
Core Design Contradiction:
Extent of automationVSLoss of time

Solution Approach 1:

The patent replaces motorized transport mechanisms with a gravity-based passive transfer system. The plug-in shafts are arranged at an incline angle, allowing objects to slide from storage compartments to the output shaft through gravity alone, eliminating the need for motors, drivers, and associated control systems, thereby reducing transfer time and maintenance requirements

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

Solution Approach 2:

The patent creates a gravity-driven system where objects naturally move from higher potential energy positions (storage compartments at the top of inclined shafts) to lower potential energy positions (output shaft at the bottom). This equipotentiality approach eliminates the need for active motorized transport, achieving automation through gravitational force alone

Inventive Principle:
Principle #12Equipotentiality

2Extent of automation

If motorized transport devices are used to transfer objects, then automation is achieved, but device complexity and maintenance requirements increase

Engineering Contradiction:
Improveautomation of object transferVSAvoidcomplexity of transport mechanism
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent eliminates motorized transport systems and replaces them with a simple gravity-based passive transfer mechanism. The inclined plug-in shafts allow objects to move automatically from storage to output without motors, drivers, or complex control systems, significantly reducing device complexity and maintenance needs

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

Solution Approach 2:

The system uses gravitational force to automatically transfer objects without requiring external power sources or active control mechanisms. The inclined shafts are designed so that objects naturally slide down to the output shaft, making the system self-sufficient and eliminating complex motorized transport components

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If vertical stacking of plug-in compartments is used to accommodate more objects, then storage capacity increases, but installation depth must be increased

Engineering Contradiction:
Improvenumber of plug-in compartmentsVSAvoidinstallation depth
Core Design Contradiction:
Quantity of substanceVSLength of stationary object

Solution Approach 1:

The patent transitions from vertical stacking (depth-oriented) to horizontal arrangement of plug-in compartments along the inclined shafts. This dimensional change allows multiple compartments to be accommodated along the length of the inclined shaft rather than stacking them vertically, increasing storage capacity without increasing installation depth

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

AI summary

The invention relates to a device for storing and outputting objects, comprising a storage container, holders, an output shaft, and a controllable holding and releasing device. The holders comprise stationary insertion shafts, in which insertion tags connected to the objects are inserted, wherein the insertion tags can be locked or released in the insertion shafts by the controllable releasing device. Upon release, the insertion tags can be transferred independently from the insertion shafts into the output shaft under gravitational force and/or spring force.
