Omnidirectional Roller Board with Elastic Biasing for Terrain Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lateral sliding roller boards and powered skateboards struggle to replicate the lateral sliding movement of snowboarding on flat or inclined terrain, limiting their adoption due to the need for specific inclines or hills, and fail to provide the unique movements associated with snowboarding.
Innovation Solution
A powered lateral sliding roller board with a platform, omnidirectional roller assemblies, and a ducted fan, where the roller assemblies are elastically biased and motor-driven, allowing for variable speed control and omnidirectional motion, enabling carving and smooth transitions between modes of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lateral sliding roller board is configured for riding down an incline, then the board can simulate snowboard movements, but the board cannot operate on flat terrain or up inclined terrain
Solution Approach 1:
The roller board incorporates dynamically adjustable roller assemblies that can change their orientation and function based on terrain requirements. The rollers are mounted on adjustable axles that allow them to pivot between lateral sliding mode (for snowboard simulation) and longitudinal rolling mode (for flat terrain and uphill movement), enabling the board to adapt to different terrains without fundamental redesign
Solution Approach 2:
The roller assemblies serve multiple functions: they can roll longitudinally like traditional skateboard wheels for flat terrain and uphill movement, and they can slide laterally across the ground to simulate snowboard movements on inclined terrain. This multi-functionality allows a single board design to operate across diverse terrains including flat surfaces, inclines, and declines
2Ease of operation
If a powered skateboard uses traditional skateboard trucks, then the rider can ride without human power, but the board cannot provide lateral sliding movement
Solution Approach 1:
The board replaces fixed skateboard trucks with dynamic roller assemblies mounted on adjustable axles. These rollers can pivot between rolling mode (enabling powered longitudinal movement) and sliding mode (enabling lateral movement perpendicular to the board's direction of travel), providing both powered riding and snowboard-like lateral sliding capabilities
Solution Approach 2:
The traditional integrated skateboard truck is segmented into separate functional components: longitudinal rolling function is provided by the roller assemblies, while lateral sliding function is enabled by the ability of these rollers to pivot and slide perpendicular to the board's longitudinal axis. This segmentation allows independent optimization of both rolling and sliding capabilities
