Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electric motors are integrated into each roller of the rollerblade, then powered transportation capability is improved, but device complexity increases
Solution Approach 1:
The rollerblade system is segmented into multiple independent powered rollers, each with its own integrated motor. This segmentation allows distributed power delivery across different contact points with the ground, improving overall propulsion capability while maintaining modular complexity that can be managed through standardized motor units.
Solution Approach 2:
The motor, roller, and roller bearing are merged into a single integrated assembly. This combination eliminates the need for separate motor mounting structures and simplifies the overall device architecture, reducing device complexity while maintaining powered transportation capability.
2Ease of operation
If a remote control system is added to actuate motors, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A remote control unit serves as an intermediary between the user and the motor control system. This mediator allows the user to operate the motors from a distance, improving ease of operation by enabling control without direct contact with the rollerblade, while the wireless communication technology keeps the added complexity manageable.
Solution Approach 2:
The control unit mounted on the boot provides localized control capabilities, allowing the system to serve itself with basic motor actuation functions. This self-service approach to control reduces the need for complex external control systems while maintaining ease of operation.
3Speed
If motors are integrated into rollers, then speed control capability is improved, but manufacturing complexity increases
Solution Approach 1:
The motor, roller, and bearing are pre-assembled into an integrated unit before installation on the rollerblade. This preliminary assembly simplifies manufacturing by allowing standardized motor-roller-bearer units to be produced independently and then installed as complete assemblies, reducing the complexity of final integration while maintaining speed control capability.

AI summary
A motorized roller blade device for automatically urging rollerblades along a support surface includes a rollerblade and a pair of motors each integrated into a respective one of a plurality of rollers of the rollerblade. Each of the pair of motors rotates the respective roller when the pair of motors is turned on to facilitate the rollerblade to be driven along the support surface. A control unit is mounted to the boot for actuating or de-actuating each of the pair of motors. A remote control is held by the user of the rollerblade and the remote control is in remote communication with the control unit for remotely actuating or de-actuating the pair of motors to facilitate the user to remotely control the pair of motors.
