Motorized Wheel Assembly With Oscillation for Uneven Ground
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
2Ease of operation
If conventional moving methods are used, then relocation is simple, but the process is labor-intensive and requires multiple people
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.
3Productivity
If the refrigerator is moved manually, then no special equipment is needed, but the process takes significant time and effort
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.
