Skateboard Deck Axle Control via Pressure Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional skateboards lack efficient control mechanisms for direction and balance, making it difficult for users to navigate smoothly and safely, especially during turns and braking.
Innovation Solution
A skateboard control method and system that uses sensor groups on the deck to detect pressure differences, allowing the skateboard to turn and move based on pressure values, with the deck fixed on an axle, enabling precise control through turning angles, speeds, and braking torques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the skateboard deck is movably connected to the axle to allow flexible inclining, then the ease of operation is improved, but the device complexity increases and stability deteriorates
Solution Approach 1:
Instead of making the deck movable relative to the axle, the patent fixes the deck to the axle and makes the axle itself rotatable. This inverts the traditional rotation mechanism from the deck side to the axle side, simplifying the connection structure while maintaining steering capability
Solution Approach 2:
The patent replaces the mechanical balance-maintaining mechanism with an electronic control system that uses sensors to detect user pressure and automatically adjusts the axle rotation to maintain balance, eliminating complex mechanical balance components
2Ease of operation
If the skateboard deck is movably connected to the axle to allow inclining, then the ease of operation is improved, but the reliability worsens due to potential falling
Solution Approach 1:
The patent employs sensors to continuously monitor user pressure distribution on the deck and feeds this information back to the control system, which automatically adjusts the axle rotation to prevent abrupt turns and maintain user balance, thereby improving safety
Solution Approach 2:
The patent replaces manual balance-maintaining operations with an electronic control system that automatically adjusts the skateboard's orientation based on sensor data, reducing the risk of user falling during direction changes
3Measurement precision
If sensor groups are arranged on the skateboard deck to detect pressure differences, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent divides the pressure detection function into multiple sensor groups arranged at different positions on the deck, with each group detecting local pressure. This segmentation enables precise determination of user stance and intended direction through comparison of pressure differences across groups
Solution Approach 2:
The sensor groups serve multiple functions: detecting user presence, determining standing position, identifying intended direction, and monitoring balance status. This multi-functionality reduces the need for separate specialized sensors for each detection task

AI summary
The present disclosure relates to a skateboard and control method thereof, in the field of skateboard control. A skateboard deck of the skateboard is fixed on an axle of the skateboard, and a first sensor group and a second sensor group are sequentially arranged on the skateboard deck in a width direction. The method includes: acquiring a first pressure value of the first sensor group and a second pressure value of the second sensor group; controlling the skateboard to turn to a first direction when the first pressure value is greater than the second pressure value and a difference value of the two pressure values is greater than a first threshold; and controlling the skateboard to turn to a second direction when the second pressure value is greater than the first pressure value, and a difference value of the two pressure values is greater than a second threshold.
