Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional friction-based braking systems are used, then braking force is achieved, but brake pads wear out and thermal energy is wasted
Solution Approach 1:
The patent replaces the conventional friction-based mechanical braking system with a gyroscopic braking system that uses rotational inertia and angular momentum. The gyroscopic body rotates about multiple axes, generating braking force through gyroscopic effects rather than friction, thereby eliminating wear and thermal energy loss.
Solution Approach 2:
The invention changes the fundamental parameter of braking from friction-based force to inertia-based force. By utilizing the gyroscopic effect and rotational dynamics, the system transforms how braking force is generated, eliminating the need for friction between brake pads and rotors.
2Loss of energy
If electrical regenerative braking systems are used, then kinetic energy is converted to electrical energy, but system complexity and cost increase
Solution Approach 1:
The patent replaces complex electrical regenerative braking systems with a purely mechanical gyroscopic braking system. The kinetic energy is managed through the rotational inertia of the gyroscopic body, eliminating the need for electric motors, generators, batteries, or capacitors while still achieving energy recovery and utilization.
Solution Approach 2:
The invention uses a simple, inexpensive gyroscopic mechanism instead of expensive electrical components. The gyroscopic braking device can be manufactured at lower cost and does not require costly electrical systems, making it an economical alternative for kinetic energy management.
3Loss of energy
If mechanical regenerative braking systems with flywheels are used, then kinetic energy is stored mechanically, but the flywheels are large and heavy
Solution Approach 1:
The invention changes the approach to mechanical energy storage by using a multi-axis gyroscopic body instead of a traditional single-axis flywheel. The gyroscopic configuration allows for more efficient use of rotational inertia, achieving the same energy storage and management capabilities with reduced weight and improved dynamics.
Solution Approach 2:
The patent employs dynamic rotational motion about multiple axes to achieve kinetic energy management. The gyroscopic body's ability to rotate about three mutually perpendicular axes allows for dynamic energy storage and release, providing better vehicle dynamics compared to static heavy flywheels.
4Force
If conventional braking systems are used, then braking force is generated, but large thermal energy is produced requiring cooling devices
Solution Approach 1:
The patent replaces the friction-based mechanical braking system that generates heat with a gyroscopic braking system that uses rotational inertia. The braking force is generated through the gyroscopic effect and angular momentum, eliminating friction and the associated thermal energy production, thus no cooling devices are required.
