Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If automated stabilization system is used, then vehicle stability is improved, but device complexity increases and reliability decreases due to electronic failure risk
Solution Approach 1:
The patent removes the complex automated stabilization electronics from the vehicle design, extracting the instability problem to be solved through passive mechanical means instead. The vehicle achieves stability through its physical design—low center of gravity, wide wheelbase, and inherent mechanical balance—rather than relying on electronic sensors and motors.
Solution Approach 2:
The vehicle is designed to be self-stabilizing through its mechanical structure, requiring no external electronic control systems. The inherent design features (low center of gravity, wheel configuration) enable the vehicle to maintain stability automatically without electronic intervention.
2Power
If combustion engine is used, then vehicle power is improved, but environmental harm increases due to exhaust emissions
Solution Approach 1:
The patent replaces the combustion engine with an electric motor, substituting a mechanical-thermal system with an electrical system. This eliminates exhaust emissions while maintaining vehicle power through electromagnetic motor operation.
3Ease of operation
If user stands on vehicle for balance control, then ease of operation is improved, but safety worsens due to trauma risk from falling
Solution Approach 1:
The vehicle design incorporates a low center of gravity that acts as a counterweight mechanism, providing inherent stability that reduces the need for active user balance control. This passive stability reduces the physical effort required while maintaining safety by minimizing fall risk through improved balance characteristics.
4Device complexity
If electric motor is integrated in wheel, then device complexity is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent combines the electric motor directly into the wheel assembly, merging two previously separate components into one integrated unit. This reduces the overall number of parts and simplifies the mechanical structure, though it requires precise manufacturing to ensure proper motor-wheel alignment and integration.

AI summary
A vehicle comprising a framework in form of beam, wheel, drive and braking system, while the vehicle is partially loaded with the weigh of user and the user stands on roller skates and holds the vehicle on the beam so that the wheel is behind the user and contacts with its tire the road surface; and when the user activates the drive, the wheel starts rotating and, as a result of friction between the wheel's tire and the road surface, there arises a force making the vehicle with user move. Additionally, another technique for operation of the same vehicle is being offered, at which the vehicle on the move is positioned in the front of user.
