Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If combustible fuel engines are used in jetpacks, then sufficient thrust and power are achieved, but heat generation increases and requires insulating protective clothing
Solution Approach 1:
The patent replaces the mechanical combustion engine system with an electrical motor system. Electric motors convert electrical energy directly to mechanical thrust without combustion, eliminating the heat generation problem while maintaining sufficient thrust capability for jetpack operation.
Solution Approach 2:
The patent changes the energy source parameter from chemical (combustible fuel) to electrical (batteries). This parameter change fundamentally alters the energy conversion process, removing the exothermic combustion reaction that causes heat generation while preserving the ability to generate adequate thrust.
2Speed
If traditional jetpack designs are used, then vertical take-off capability is achieved, but flight time is very short due to high energy consumption
Solution Approach 1:
The patent replaces the high energy consumption combustion engine with an electrical motor system that can be powered by rechargeable batteries. This substitution reduces overall energy consumption while extending flight duration, as electrical motors are more efficient and batteries can store sufficient energy for longer operation.
Solution Approach 2:
The patent enables periodic operation through rechargeable batteries that can be recharged between flights. This periodic action allows the system to accumulate energy over time, effectively extending the operational duration beyond what a single fuel tank could provide.
3Speed
If reaction principle jetpacks are used, then personal flight is achieved, but controlled landing is not possible
Solution Approach 1:
The patent employs dynamic control systems with electric motors that can independently adjust thrust levels and direction. This dynamic capability enables precise control during landing, allowing the operator to modulate power output and achieve controlled descents and landings, unlike fixed reaction principle systems.
Solution Approach 2:
The patent incorporates feedback control systems that monitor flight parameters and adjust motor output accordingly. This feedback mechanism enables the operator to maintain stable flight and execute controlled landings by receiving continuous information about the system's state and making appropriate adjustments.
4Object-generated harmful factors
If electric motors are used instead of combustion engines, then heat and noise are reduced, but flight time is limited by battery capacity
Solution Approach 1:
The patent changes the energy storage parameter from limited fuel tanks to rechargeable batteries with higher energy density. This parameter change extends flight time while maintaining the low heat and noise advantages of electric motors, as batteries can be recharged and have sufficient capacity for extended operation.
Solution Approach 2:
The patent enables continuous useful action through rechargeable batteries that can be recharged between flights. This continuity allows the system to maintain low heat and noise operation while effectively extending total operational duration through repeated charging cycles.

AI summary
The Electric Jetpack Device has multiple electric ducted or clustered electric jets to create enough/sufficient controlled thrust with battery power alone. It is a lightweight vertical take-off with the electrical power of rechargeable batteries for a safe, vertical lift off vehicle. It is capable of carrying an average human or equivalent payload and flying for several minutes per charge. Motors and propellers are powered by the batteries and managed through an Electronic Speed Controller and a flight controller. The Flight Controller balances thrust and limits roll from side to side. By moving the control handles connected and mounted to an aluminum frame, the device and craft is directed. The pivots tilt the cluster of jetpacks slightly forward or back. The frame is connected to a harness, in which the pilot is strapped. The craft is modular and can be connected to another craft creating a “quadcopter” set-up.
