Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If large motors and associated gearing are used to provide electric power assistance, then sufficient power is delivered, but the device becomes cumbersome and costly
Solution Approach 1:
The patent merges the electric motor, battery, control electronics, and wheel into a single integrated assembly that fits within the footwear. This consolidation eliminates the need for separate motor housing, transmission systems, and supporting structures, thereby delivering sufficient power while minimizing device complexity and bulk
Solution Approach 2:
The motor is positioned centrally within the wheel structure, with the battery and control electronics nested within or adjacent to the motor assembly. This nested arrangement maximizes space utilization and minimizes the overall footprint of the powertrain system
2Power
If large motors and associated hardware are used, then sufficient power is delivered, but the device becomes costly
Solution Approach 1:
The integration of motor, battery, and control systems into a single modular assembly reduces manufacturing steps, assembly operations, and associated labor costs. The compact design allows for standardized production techniques and reduces the need for expensive custom fabrication
Solution Approach 2:
The patent employs cost-effective materials and construction methods appropriate for consumer footwear, utilizing readily available components and simplified manufacturing processes that reduce production costs while maintaining adequate performance for the intended application
3Power
If large motors and associated hardware are used, then sufficient power is delivered, but storage and parking become difficult
Solution Approach 1:
The motor is positioned centrally within the wheel structure, with the battery and control electronics nested within or adjacent to the motor assembly. This nested arrangement maximizes space utilization and minimizes the overall footprint of the powertrain system
Solution Approach 2:
The electric motor, battery, control electronics, and wheel are merged into a single integrated assembly that fits within the footwear, eliminating the need for separate motor housing and supporting structures, thereby minimizing the volume required for storage
4Power
If large motors and associated hardware are used, then sufficient power is delivered, but maintenance becomes difficult
Solution Approach 1:
The integration of motor, battery, and control systems into a single modular assembly simplifies maintenance by reducing the number of separate components that require individual attention. The compact design allows for easier access and potential replacement as a single unit
Solution Approach 2:
The sealed, integrated design protects internal components from environmental contaminants and reduces the need for routine maintenance. The system is designed to be largely maintenance-free, with components selected for durability and resistance to wear
5Power
If large motors and associated hardware are used, then sufficient power is delivered, but the center of mass is substantially changed
Solution Approach 1:
The motor is positioned centrally within the wheel structure, with the battery and control electronics nested within or adjacent to the motor assembly. This nested arrangement maximizes space utilization and minimizes the overall footprint of the powertrain system
Solution Approach 2:
The powertrain components are strategically positioned within the footwear to optimize the center of mass location. The motor is placed centrally within the wheel, and the battery is positioned to balance the overall weight distribution, minimizing adverse effects on performance

AI summary
An exemplary motorized personal transportation apparatus is provided that may include a motorized heeling apparatus, a motorized heel bracket or a motorized wheel assembly. The motorized heeling apparatus may include a heeling apparatus and an electric motor mounted adjacent the heeling apparatus to impart forward rotation to at least one wheel adjacent the heel of a footwear to allow walking/running on forefoot, and transition to passive rolling and then electric powered rolling.The motorized heel bracket may include a heel support structure, which may be incorporated in footwear, for supporting at least a portion of the user's heel, wheel(s) mounted adjacent the heel bracket, and an electric motor positioned adjacent the heel support structure and operable to impart forward rotation to the wheel(s).The motorized wheel assembly includes an electric motor with a wheel around the motor such that the casing or external housing rotates to impart rotation to the wheel assembly. The wheel assembly may be used in virtually any transportation apparatus moving platforms, and footwear.
