Omnidirectional Wheel Staggered Bracket Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional omnidirectional wheels suffer from uneven wear patterns, where minor wheels wear out faster than major wheels, leading to premature replacement of the entire wheel assembly even when major wheels are still intact.
Innovation Solution
The omnidirectional wheel design features major and minor brackets arranged in a staggered manner, with major wheels rotating orthogonally and minor wheels rotating at an angle, increasing lateral force on minor wheels and reducing contact time, thereby reducing abrasion and extending the lifespan of minor wheels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the omnidirectional wheel uses major wheels and minor wheels in a staggered arrangement, then the wheel can achieve omnidirectional movement, but the minor wheels wear out much faster than the major wheels
Solution Approach 1:
The invention divides the wheel assembly into independently replaceable major wheels and minor wheels. The minor wheels are designed as separate, detachable components that can be replaced individually without replacing the entire wheel assembly or the major wheels, thus resolving the contradiction by enabling selective replacement of worn minor wheels while preserving functional major wheels.
Solution Approach 2:
The invention changes the structural parameters of the minor wheels by providing different types of minor wheels (first type and second type) with different configurations. This allows optimization of the minor wheel design to reduce wear and extend service life while maintaining the omnidirectional movement capability of the overall wheel system.
2Productivity
If the minor wheels have higher rolling frequency to enable omnidirectional movement, then maneuverability is improved, but wear and damage occur more quickly
Solution Approach 1:
By segmenting the wheel system into major and minor wheels that can be independently replaced, the invention allows the minor wheels to operate at high rolling frequencies for improved maneuverability while knowing they can be replaced individually when worn, thus maintaining reliability without sacrificing productivity.
Solution Approach 2:
The invention treats minor wheels as consumable components that are expected to wear out faster and are replaced individually. This approach accepts the shorter service life of minor wheels as a trade-off for achieving the desired maneuverability, while the overall system reliability is maintained through easy replacement of these short-living components.
