Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing domestic radiator wheel assemblies are complex, expensive, and generate significant friction, making them difficult to assemble and maneuver, especially when moving around corners.
Innovation Solution
A simplified wheel assembly design featuring an axle with elastic fittings at each end, where each hub is securely attached to the axle and each wheel is rotatable, reducing the number of parts and tool requirements, allowing independent wheel rotation and minimizing friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wheels are rigidly attached to the axle, then the assembly is simple and robust, but maneuverability deteriorates when moving around corners
Solution Approach 1:
The wheel assembly is segmented into independent rotatable hubs that can turn independently on the axle, separating the functions of support (axle) and maneuvering (rotatable hubs), thus achieving both structural simplicity and good maneuverability when moving around corners
2Ease of operation
If independent wheel rotation is allowed to improve maneuverability, then maneuverability improves, but device complexity increases requiring many parts and tools
Solution Approach 1:
The hub and wheel are merged into a single rotatable assembly that fits onto the axle, combining multiple functions (support, rotation, maneuvering) into one integrated component, reducing the total number of parts while maintaining independent wheel rotation capability
3Ease of operation
If complex assembly mechanisms are used to allow independent wheel rotation, then maneuverability improves, but ease of assembly deteriorates requiring tools and expertise
Solution Approach 1:
Instead of attaching wheels to a fixed axle, the invention inverts the approach by having the axle fit into rotatable hubs, allowing the hubs to rotate independently on the axle, achieving independent wheel rotation with simple tool-free assembly
4Ease of operation
If multiple rotating parts are used to allow independent wheel rotation, then maneuverability improves, but reliability deteriorates due to friction and twisting
Solution Approach 1:
The invention extracts the rotation capability from the axle itself and places it in the hubs, allowing only the hubs and wheels to rotate while the axle remains stationary, eliminating friction and twisting problems associated with rotating axles while maintaining independent wheel rotation
