Solution Overview
Problem
Current vehicle drive systems rely on friction between tires and the road surface for propulsion, which can lead to slippage on low-friction surfaces like ice or mud, resulting in loss of control and energy inefficiency.
Innovation Solution

Engineering Contradiction Analysis
1Reliability
If traditional friction-based tire propulsion is used, then vehicle can propel on high-friction surfaces, but slippage and loss of control occur on low-friction surfaces like ice or mud
Solution Approach 1:
The patent replaces the traditional friction-based mechanical propulsion system with a gravitational propulsion system. The spherical vehicle uses internally rotating weights that generate gravitational force to propel the vehicle forward, eliminating dependence on tire-road friction. This substitution resolves the slippage problem by using gravity rather than friction as the propelling force.
Solution Approach 2:
The patent changes the fundamental propelling parameter from friction-based horizontal force to gravity-based vertical force conversion. By using rotating weights to convert gravitational potential energy into kinetic energy, the system maintains reliable propulsion across all surface conditions, including low-friction surfaces where traditional systems fail.
2Use of energy by moving object
If friction-based propulsion is used, then vehicle can achieve propulsion on dry surfaces, but energy is lost due to slippage
Solution Approach 1:
The patent substitutes the friction-dependent mechanical transmission system with a direct gravitational propulsion mechanism. The rotating weights directly convert gravitational energy into vehicle motion without requiring friction-based tire propulsion, thereby eliminating energy loss through slippage and improving overall propulsion efficiency.
3Ease of operation
If traditional steering mechanisms and gearboxes are used, then vehicle can control travel direction and torque, but large turning radius is required
Solution Approach 1:
The patent employs dynamic control of the spherical vehicle by independently adjusting the rotation of multiple weights. By changing the rotational speed and position of weights during movement, the vehicle can dynamically alter its trajectory and achieve tight turning radii without traditional steering mechanisms, allowing directional control in a much smaller area.
Solution Approach 2:
The patent divides the propulsion system into multiple independent rotating weight components, each capable of independent control. This segmentation allows the vehicle to control direction by differential rotation of weights, replacing traditional steering mechanisms and enabling tighter turning radii through distributed control rather than centralized steering.
4Power
If internal combustion engines and gearboxes are used, then vehicle can provide power and torque control, but device complexity increases
Solution Approach 1:
The patent replaces complex internal combustion engines and gearbox systems with a simplified gravitational propulsion system using rotating weights. The weights, when rotated, directly generate propulsive force through gravity, eliminating the need for combustion chambers, pistons, valves, and multi-speed gearboxes, thereby significantly reducing device complexity while maintaining propulsion capability.
Solution Approach 2:
The rotating weight system serves multiple functions simultaneously: it generates propulsive force, controls vehicle speed, and enables directional control, replacing what would traditionally require separate engine, transmission, and steering systems. This multi-functionality reduces overall device complexity while maintaining full propulsion and control capabilities.

AI summary
A propulsion apparatus and corresponding methods are provided. The apparatus employs weights within a spherical assembly that can rotate within the spherical assembly. Gravity, acting on the weights, causes a moment of a gravitational force to be applied to the spherical assembly, which can cause the spherical assembly to propel. The spherical assembly may also include one or more motors to rotate the weights within the spherical assembly. In some embodiments, the weights include magnetic cores and conductors. The apparatus can include magnetic windings that provide a magnetic flux through which the weights may rotate. The apparatus can also provide an electrical current to the conductors. As the weights with the magnetic cores rotate through the magnetic flux, the apparatus applies a current to the conductors. As such, a magnetic force is applied to the weights, which can propel the spherical assembly.
