Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid framework is used to connect propulsion devices with wings, then structural stability is improved, but device complexity and weight increase
Solution Approach 1:
The patent removes the rigid framework and wings from the system, extracting only the essential propulsion devices that can be worn on the body. The human body itself serves as the supporting structure, eliminating the need for complex external frameworks while maintaining flight capability through direct body-mounted propulsion units.
Solution Approach 2:
The human body's natural strength, balance, and kinesthetic senses are utilized to control and stabilize the flight system. The wearer's own physiological capabilities serve the function of maintaining stability and controlling thrust direction, eliminating the need for artificial stabilization mechanisms.
2Ease of operation
If propulsion assemblies are mounted on the user's forearms and torso, then ease of operation is improved by using natural balance senses, but weight distribution and structural load increase
Solution Approach 1:
The propulsion assemblies are distributed to specific locations on the body (forearms and torso) where they can effectively utilize local muscle groups and skeletal structures for support. This localized mounting strategy optimizes the use of specific body regions' strength characteristics while maintaining overall balance and control.
3Reliability
If multiple propulsion assemblies are used to distribute load, then reliability is improved, but device complexity increases
Solution Approach 1:
The flight system is divided into multiple independent propulsion assemblies mounted on different parts of the body. Each propulsion unit operates semi-independently, providing redundant thrust capability and load distribution. This segmentation enhances reliability by ensuring that failure of one unit does not compromise the entire system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides stable flight without the need for rigid frameworks, allowing users to support their weight and navigate with ease, maintaining consistent thrust and stability through body alignment and fuel management.
Implementation Method 1
Each propulsion assembly is able to provide a maximum thrust of at least 400N... The thrust provided by a propulsion assembly produces an equal and opposite force on the user
Implementation Method 2
the difficult control problem of correctly angling a variety of thrusts produced by a plurality of propulsion assemblies may be delegated to the wearer's natural senses of balance, proprioception, and kinesthesia

AI summary
A disclosed device allows a person to fly. A disclosed wearable flight system includes a plurality of propulsion assemblies including a left-hand propulsion assembly configured to be worn on a user's left hand and/or forearm and a right-hand propulsion assembly configured to be worn on a user's right hand and/or forearm. A further embodiment includes a body propulsion device that is configured to provide a net force along an axis defining a net body propulsion vector and a support device configured to support a user's waist or torso. The support device is configured to hold a user's body relative to the body propulsion device such that a line extending between center the of the user's head and the center of the user's waist extends, relative to the orientation of the net body propulsion vector during use, by a body propulsion elevation angle that is greater than zero.
