Container Wheel System with Telescopic Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheeled containers, such as trash containers, often have a narrow wheel base and narrow wheels, leading to instability and difficulty in moving over various surfaces like grass, snow, and soft ground, especially when full.
Innovation Solution
A wheel system that can be connected to existing wheels to increase the wheel width and base, featuring a wheel cover made from materials like plastic, rubber, or metal, which can be designed with a non-smooth surface for improved traction and a telescopically receiving cavity to enhance stability and ease of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If narrow wheels and narrow wheel base are used, then the device complexity is reduced and manufacturing is easier, but the stability deteriorates and the container tips easily when rolled
Solution Approach 1:
The wheel cover is designed to telescopically receive the existing wheel, with the cover fitting over the wheel like a nested structure. The cavity of the wheel cover is configured to accommodate the wheel while maintaining a telescopic connection, allowing the wheel to rotate within the cover without requiring complex integration mechanisms.
Solution Approach 2:
The wheel cover increases the width dimension of the wheel system by extending laterally beyond the original wheel width. This dimensional addition widens the wheel base without increasing the vertical height significantly, thereby improving stability through a different spatial dimension rather than simply making the wheel larger in all dimensions.
2Ease of operation
If narrow wheels are used, then the device complexity is reduced, but the ease of operation deteriorates when pulling over grass, snow, soft ground surfaces
Solution Approach 1:
The wheel cover is designed to telescopically receive the existing wheel, with the cover fitting over the wheel like a nested structure. The cavity of the wheel cover is configured to accommodate the wheel while maintaining a telescopic connection, allowing the wheel to rotate within the cover without requiring complex integration mechanisms.
Solution Approach 2:
The wheel cover increases the width dimension of the wheel system by extending laterally beyond the original wheel width. This dimensional addition widens the wheel base without increasing the vertical height significantly, thereby improving stability through a different spatial dimension rather than simply making the wheel larger in all dimensions.
3Stability of the object's composition
If wheel cover diameter is increased to improve stability, then the stability improves, but the device complexity increases and may interfere with existing container structures
Solution Approach 1:
The wheel cover is designed with a non-uniform diameter configuration where the majority of the cover's diameter extends beyond the wheel diameter to provide stability, but the cavity portion that contacts the wheel maintains a diameter matched to the wheel. This localized differentiation allows the cover to provide stabilizing width without creating excessive overall diameter that would interfere with container structures.
Solution Approach 2:
The wheel cover is designed to telescopically receive the existing wheel, with the cover fitting over the wheel like a nested structure. The cavity of the wheel cover is configured to accommodate the wheel while maintaining a telescopic connection, allowing the wheel to rotate within the cover without requiring complex integration mechanisms.
