Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional transmissions and drive trains are used to convert rotational energy to linear motion, then the vehicle can be propelled, but energy loss and friction wear occur

Engineering Contradiction:
Improveenergy lossVSAvoidfriction wear
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent replaces conventional mechanical transmission systems with an inertial reaction mass system. Instead of using gears, belts, and shafts to convert rotational motion to linear motion, the invention uses the centrifugal force generated by rotating inertial masses to directly produce thrust through reaction forces, eliminating the need for complex mechanical power transmission components that cause friction and energy loss.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The inertial masses themselves generate the thrust force through their rotation and the reaction forces they produce. The system does not require external mechanical transmission components to convert motion types, as the rotating masses directly create the propulsive force through their inertial properties, making the system self-sufficient and eliminating frictional losses in transmission mechanisms.

Solution Approach 1:

The patent employs dynamically controllable inertial masses that can be independently controlled in terms of both magnitude and direction of their reaction forces. The system uses controllable mass acceleration and deceleration phases, along with adjustable mass distribution and rotation characteristics, to dynamically shape the thrust vector in any direction, providing full adaptability in thrust control.

Solution Approach 2:

The invention divides the thrust generation function into multiple independent inertial mass units, each capable of producing controllable reaction forces. By segmenting the total thrust into contributions from individual masses, the system can independently control the direction and magnitude of each mass's reaction force, enabling versatile thrust vector control that overcomes the limitations of single-axis or fixed-direction designs.

AI summary

A device that produces linear motion by sequentially and in a continuous sequence accelerating inertial thrust masses at well-defined times towards the axis of counter-rotating disks. The inertial thrust masses are contained in cavities placed equidistantly about the periphery of counter rotating capture disks mounted on a common axle. They are radially accelerated by a bi-directional impulse ramps that can be moved to any position around the periphery of the counter rotating capture plates and into and out of the paths of the gyrating thrust masses to any desired depth within the mechanical range of the impulse ramps which simultaneously engage and radially accelerate the inertial thrust masses of each counter-rotating capture plate.
