Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If lithium batteries are used as the power source for electrically driven hovercars, then the hovercar can achieve vertical take-off and landing capability, but the flight duration is limited to about 20 minutes and flight distance is only tens of kilometers
Solution Approach 1:
The patent combines a hydrogen fuel cell system with an electric motor system to create a hybrid power plant. The hydrogen reactor generates electricity through electrochemical reactions, which is then used to drive the motor that powers the propeller, thereby extending flight duration beyond what lithium batteries alone can achieve
Solution Approach 2:
The hydrogen fuel cell system serves multiple functions: it generates electrical energy for the motor, produces thermal energy that can be utilized, and enables longer operational duration. This multi-functional approach addresses both the energy capacity and duration limitations of battery-only systems
2Force
If the hovercar structure is designed for vertical take-off and landing, then flexible take-off and landing without runway is achieved, but the thrust generation capability is insufficient for forward flight
Solution Approach 1:
The patent merges the vertical take-off capability (from electrically driven propellers) with forward thrust capability (from the hydrogen-fueled propulsion system) into a single integrated power plant, enabling both hover and forward flight modes without requiring separate systems
3Duration of action of moving object
If a hydrogen reactor is added to create a hybrid power system, then flight duration and thrust are improved, but the device complexity increases
Solution Approach 1:
The hydrogen reactor system is designed to perform multiple functions simultaneously: power generation through electrochemical reactions, thermal management through controlled reactions, and fuel storage. This multi-functionality reduces the need for separate dedicated systems, thereby limiting the increase in overall device complexity while achieving extended endurance

The hydrogen electric hybrid power plant enhances hovercar endurance and acceleration, reduces weight, and increases flight distance by providing a reliable electric power source and forward propulsion, overcoming the limitations of airborne batteries and thrust generation.
Implementation Method 1
A hydrogen reactor is arranged in the first-stage duct
Implementation Method 2
One end of a return pipe is arranged at an outlet end of the first-stage duct, and the other end of the return pipe is connected into a rear end of the filter and an inlet of the hydrogen reactor
Implementation Method 3
Some warm and humid airflow and liquid water are returned to the inlet of the hydrogen reactor through the return pipe. The returned warm and humid air low and liquid water can effectively heat and humidify internal materials of the hydrogen reactor
Implementation Method 4
A motor is electrically connected with a turbofan, and the turbofan is installed in the transition duct or the second-stage duct
