Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional snowboard design is used, then the structure remains simple and easy to manufacture, but the user cannot easily control and manage movement across different snow conditions and terrain surfaces
Solution Approach 1:
The snowboard is divided into functional modules: a traditional snowboard body for riding, and a separate controllable propulsion assembly with drive belts and motors that can be independently operated to assist movement across different terrains
Solution Approach 2:
The propulsion assembly with dual drive belts is designed to perform multiple functions: propelling the snowboard forward, providing traction on varied snow conditions, and enabling controlled descent, making the system adaptable to different snowboarding scenarios
2Adaptability or versatility
If existing snowboard designs are used, then the device complexity remains low, but the user cannot independently control and glide across different snow conditions or terrains
Solution Approach 1:
The propulsion assembly incorporates adjustable drive belts that can dynamically adapt to different snow conditions and terrain types, allowing the system to optimize its performance characteristics for each specific environment
Solution Approach 2:
The controllable propulsion assembly enables the snowboard to self-propel and self-steer across different terrains without requiring external assistance, with the drive system automatically adjusting to maintain optimal traction
3Ease of operation
If a controllable propulsion assembly is added to enable user control, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The propulsion assembly is designed as a separate module that can be manufactured independently and then integrated with the traditional snowboard, allowing each component to be optimized for its specific manufacturing process
Solution Approach 2:
Drive belts serve as intermediary elements that connect the motorized propulsion system to the snowboard, providing a flexible coupling that simplifies the transmission of power while accommodating manufacturing tolerances

AI summary
The present invention discloses a personal transportation device comprising a frame structure, a board platform, and a propulsion assembly. The board platform mounted on an upper portion of the frame to support a standing rider. The propulsion assembly mounted to a lower portion of the frame comprises an axle assembly, a first wheel assembly, a second wheel assembly, an endless drive unit, a drivetrain assembly, and a suspension system. The axle assembly comprises a first axle and a second axle opposite to the first axle. Each axle comprises a pair of wheels. The endless drive unit is engaged with the wheels to rotate in response to the wheel rotation to propel the device. The drivetrain assembly coupled to the axle assembly comprising a motor assembly. Each motor transfers rotational energy to the wheels. A suspension assembly connected between the frame structure and wheels to enable multidimensional articulation and absorb vibrations.
