Double-Sided Wheel Assembly for Luggage Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage wheels have a limited turning radius due to their single-wheel design, which restricts maneuverability in crowded areas, poses safety risks, and limits luggage load capacity.
Innovation Solution
A double-sided wheel assembly featuring multiple wheels, including a first wheel, a second wheel, and a center member, which distributes the load and reduces ground contact, allowing for improved turning radius and load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single wheel is used in luggage, then the structure is simple, but the turning radius is limited and maneuverability is poor
Solution Approach 1:
The single wheel is segmented into multiple wheels (first wheel and second wheel) arranged side by side. This segmentation allows the luggage to pivot more easily between the wheels, improving the turning radius and maneuverability in crowded areas while maintaining structural simplicity through the shared center member and carriage.
2Strength
If a single wheel is used in luggage, then the device complexity is low, but the load capacity is limited
Solution Approach 1:
The load-bearing function is segmented across multiple wheels (first wheel and second wheel), distributing the luggage weight and increasing overall load capacity. The center member and carriage provide structural support to handle the increased load while maintaining a relatively simple overall structure.
3Ease of operation
If a single wheel contacts the ground, then the ground contact area is large, but this resists wheel rotation and limits turning radius
Solution Approach 1:
The ground contact is segmented from a single large contact patch into two smaller contact patches (first wheel and second wheel). This segmentation reduces the frictional resistance at each contact point, allowing easier rotation and tighter turning radius while still maintaining stable ground contact.
