Solution Overview

Problem

Existing storage systems with mobile cabinets face challenges in manual movement, especially for large cabinets, due to the need for manual rotation of handwheels and issues with rail inclination causing gravity displacement, which are not easily addressed by existing safety devices or motorization solutions that are complex and difficult to install.

Innovation Solution

A motorization kit for storage systems with mobile cabinets, featuring a box-like body housing an electric motor, driven pinion, mechanical drive means, electronic adjustment and control systems, and safety sensors, allowing for automatic and wireless operation, including photocell sensors for obstacle detection and speed reduction, and eliminating the need for extensive wiring or customization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual rotation of handwheels is used to move large cabinets, then the cabinets can be moved along the rails, but the operation becomes physically demanding and inefficient

Engineering Contradiction:
Improveease of cabinet movementVSAvoidtime required for manual operation
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical handwheel system with an electric motor system. The motor is connected to the pinion gear through a gear reduction mechanism, automatically providing the rotational force needed to move the cabinet along the rack, thereby eliminating manual physical effort and reducing operation time.

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

Solution Approach 2:

The motorized system enables the cabinet to move itself without external manual intervention. The electric motor, powered through the control system and battery, autonomously drives the pinion gear to engage with the rack, allowing the cabinet to self-propel along the rails.

Inventive Principle:
Principle #25Self-service

2Reliability

If safety devices such as brakes are engaged to prevent gravity displacement on inclined floors, then cabinet stability is improved, but the system complexity and installation difficulty increase

Engineering Contradiction:
Improvecabinet stability on inclined surfacesVSAvoidcomplexity of safety device installation
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical brake systems with an electronically controlled motor system. The motor, controlled by electronic sensors and control circuits, can automatically engage and disengage to prevent gravity-driven displacement on inclined surfaces, thereby achieving stability without requiring complex mechanical brake installations.

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

Solution Approach 2:

The system incorporates sensors that detect the inclination of the floor and provide feedback to the control system. Based on this feedback, the control system automatically adjusts the motor operation to prevent unintended cabinet movement on inclined surfaces, eliminating the need for complex mechanical safety devices.

Inventive Principle:
Principle #23Feedback

3Extent of automation

If motorized drive systems are installed at pinions meshing with floor-mounted racks, then automatic cabinet movement is achieved, but the difficulty of installation and electrical connection increases

Engineering Contradiction:
Improveautomation of cabinet movementVSAvoidease of motor installation
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The patent divides the motorized drive system into modular components: the electric motor, the pinion gear, the battery, and the control system are separate, independently installable units. This segmentation allows each component to be installed and connected separately, reducing the overall installation difficulty and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The motor assembly is designed as a universal module that can be adapted to different cabinet types and rack configurations. The standardized mounting brackets and electrical connections allow the same motor unit to be installed on various cabinet models, thereby simplifying the manufacturing and installation process.

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

4Reliability

If extensive wiring and customization are required for motorization, then proper power supply and control are ensured, but the installation time and cost increase

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system incorporates a battery pack that is pre-installed and pre-charged, eliminating the need for complex electrical wiring during installation. The battery provides portable power that can be easily connected to the motor, thereby ensuring reliable power supply while significantly reducing installation time and complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces extensive electrical wiring with a simplified electrical connection system. The motor is designed with plug-and-play electrical connectors that can be easily attached to the battery and control system, thereby ensuring reliable power and control connections while minimizing installation time and reducing the need for professional electrical wiring.

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