Solution Overview

Problem

Existing motorized wheels for vehicles have large dimensions, leading to limited lateral extension of the bedplate, high center of gravity, inefficiency on uneven ground, and structural fragility, limiting their versatility and stability.

Innovation Solution

A compact, sturdy appliance with motorized wheels featuring a gearmotor-driven first wheel and a freely rotating second wheel, housed within the wheel hub, with a reduction unit and steering assembly, allowing for efficient load bearing and improved drivability on uneven terrain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a refrigerator is relocated by tilting and sliding it, then it can be moved to a new position, but the appliance may become damaged or injure persons during the process

Engineering Contradiction:
Improverelocation easeVSAvoidappliance safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the traditional mechanical tilting and sliding method with an automated robotic system equipped with sensors, motors, and controlled movement mechanisms. This substitution eliminates manual handling risks while providing precise, damage-free relocation of the refrigerator through electronically controlled transport.

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

2Ease of operation

If conventional moving methods are used, then relocation is simple, but the process is labor-intensive and requires multiple people

Engineering Contradiction:
Improverelocation simplicityVSAvoidmoving system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The refrigerator relocation system is designed to operate autonomously without human intervention. The appliance itself becomes the moving platform, with integrated sensors detecting obstacles and controlling the robotic mechanisms that transport it, thereby eliminating the need for multiple workers while maintaining simple operation through automated self-navigation.

Inventive Principle:
Principle #25Self-service

3Productivity

If the refrigerator is moved manually, then no special equipment is needed, but the process takes significant time and effort

Engineering Contradiction:
Improverelocation speedVSAvoidmoving equipment complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The robotic relocation system is designed as a universal platform capable of transporting various heavy appliances, not just refrigerators. By creating a multi-functional device that can handle different appliance types and sizes, the system achieves high relocation speed and efficiency while justifying the equipment complexity through broad applicability across multiple moving scenarios.

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