Electric Skateboard Remote Battery Mounting and Drive Hub
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard motorized skateboards with onboard batteries face challenges in handling and torque due to the weight and placement of the battery, which affects the overall performance and usability.
Innovation Solution
A motorized skateboard design with a remote power supply, allowing the battery to be carried separately and integrated wiring techniques, along with a removable and interchangeable motor mount, enables improved handling and increased torque without modifying the standard skateboard deck, using standard wheels as drive wheels and securing the equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is mounted on the skateboard deck, then the power supply is integrated and stable, but the handling becomes difficult due to increased weight and altered center of gravity
Solution Approach 1:
The power supply system is segmented into separate components: the battery pack is detached from the skateboard deck and can be carried independently by the user (e.g., in a backpack or hand), while the skateboard retains only the motor, controller, and minimal wiring. This separation resolves the contradiction by maintaining power supply functionality without compromising handling.
Solution Approach 2:
The battery is extracted from the skateboard deck and relocated to an external position carried by the user. This extraction eliminates the negative impact of battery weight and positioning on handling while preserving the power supply function through external connection via wiring.
2Ease of operation
If the battery is removed from the skateboard, then the handling improves, but the power supply becomes remote and requires wiring connections
Solution Approach 1:
The wiring system is designed with universal connection points at both the skateboard (front and back of deck) and the battery pack, allowing flexible connection configurations. This multi-functionality enables the system to accommodate various battery positions and user preferences without increasing complexity, as the same wiring harness can connect to different locations.
Solution Approach 2:
The wiring connection system is made dynamic and adaptable, with connection points positioned at multiple locations (front and back of deck) to allow flexible routing. This dynamic design accommodates different user needs and battery positions without requiring complex fixed installations.
3Adaptability or versatility
If standard skateboard wheels are used as drive wheels, then compatibility with standard skateboards is maintained, but the torque transmission may be insufficient
Solution Approach 1:
The drive hub is pre-engineered with integrated toothed engagement features that mate with the motor output. This preliminary design ensures that when standard wheels are installed on the hub, torque transmission is immediately effective without requiring modification of the wheels themselves, thus maintaining compatibility while ensuring sufficient torque.
Solution Approach 2:
The drive hub acts as an intermediary component between the motor and the standard skateboard wheels. It provides the necessary mechanical interface (toothed engagement) to transmit torque effectively from the motor to the wheels, while still allowing standard wheels to be used, thus resolving the contradiction between compatibility and torque transmission.
4Stability of the object's composition
If the motor mount is fixed to the deck, then the motor alignment is stable, but modifications to the standard skateboard deck are required
Solution Approach 1:
The motor mounting system is segmented into a separate, removable motor mount that attaches to the skateboard truck rather than requiring direct modification of the deck. This segmentation allows stable motor alignment through the truck mounting interface while preserving the integrity and standard configuration of the skateboard deck.
Solution Approach 2:
The motor mount is designed as a universal component that interfaces with standard skateboard truck mounting patterns. This multi-functionality allows the motor to be securely mounted with stable alignment without requiring custom modifications to specific deck designs, as it utilizes the existing standardized truck interface.

AI summary
Embodiments relate to a motorized skateboard. Embodiments allow users to utilize a power supply, such as a rechargeable battery pack, that is remote with respect to the skateboard. Embodiments can have the battery mounted on, under, partially or wholly enclosed within, and/or integral with the skateboard deck. Embodiments can have a removable and interchangeable motor mount, which attaches to the hanger to align the motor with the drive train. The drive wheel adaptor (hub) allows the user to modify standard skateboard wheels to use as drive wheels for the electric skateboard. The strength of the bond between the drive hub and the wheel enables the skateboard to utilize more torque without failure. Embodiments can allow users to have wiring connections at the front and/or back of the skateboard deck. Board-integrated wiring techniques can also be utilized. The electronics can be attached using brackets that fit the industry standard bolt pattern.
