Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If fixed wings are attached to the chassis or engines, then the aircraft can provide lift during horizontal flight, but the aircraft experiences instability and increased energy consumption during takeoff, landing, and hovering in windy conditions
Solution Approach 1:
The patent applies the dynamics principle by making the wings free to rotate around their longitudinal axis rather than being fixed to the chassis or engines. This allows the wings to dynamically adjust their orientation in response to wind conditions, automatically optimizing their position to minimize drag and maintain stability during takeoff, landing, and hovering operations. The rotational freedom enables the wings to adapt to changing airflow patterns without requiring active control mechanisms.
Solution Approach 2:
The free-rotating wings embody the self-service principle by autonomously responding to wind conditions through passive aerodynamic forces. The wings automatically orient themselves to reduce drag and maintain stable flight characteristics without requiring external control systems, sensors, or energy input. This self-adjusting mechanism eliminates the need for complex stabilization systems while improving energy efficiency and stability.
2Productivity
If fixed wings are used to enhance energy efficiency in horizontal flight, then lift is improved, but drag and instability increase during vertical flight phases in windy conditions
Solution Approach 1:
The patent implements dynamics by enabling the wings to rotate freely around their longitudinal axis, allowing them to dynamically adapt to wind conditions during vertical flight phases. This rotational freedom enables the wings to automatically adjust their orientation to minimize the harmful effects of wind, reducing drag and instability during takeoff, landing, and hovering while maintaining flight efficiency during horizontal operation.
Solution Approach 2:
The invention applies parameter changes by allowing the wing orientation parameter to vary dynamically during flight. The wings can change their angular position relative to the airflow depending on the flight phase and wind conditions, optimizing performance across different operating regimes. This parameter adaptation reduces the negative impact of wind during vertical flight while preserving aerodynamic efficiency during horizontal flight.
3Stability of the object's composition
If actuators and mechanical mechanisms are added to stabilize the aircraft, then stability improves, but reliability decreases and weight increases
Solution Approach 1:
The patent applies self-service by eliminating the need for actuators and mechanical stabilization mechanisms. The free-rotating wings autonomously provide stability through passive aerodynamic forces, automatically adjusting their orientation in response to wind conditions. This removes critical failure points associated with active control systems, thereby improving reliability while maintaining stability enhancement.
Solution Approach 2:
The invention extracts and removes the complex mechanical stabilization systems (actuators, sensors, control mechanisms) that would otherwise be needed to achieve stability. By replacing these active systems with passive, free-rotating wings, the patent eliminates potential failure points while achieving the desired stability effect through purely aerodynamic means.
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
Enhances flight efficiency, reduces energy consumption, and improves stability by allowing the wings to respond to wind conditions, maintaining altitude and control during various flight phases.
Implementation Method 1
a free wing that can rotate freely around its longitudinal axis, thus providing the aircraft with lift during horizontal flight
Implementation Method 2
The free wings may be either controlled by an actuator or they may be uncontrolled, in which case the angle and lift they produce are a result of the flow of air in relation to them

AI summary
A multirotor aircraft that includes a chassis, at least three engines that are equipped with propellers, and one or more axial free wings that are connected to the chassis by axial connections. The leading edges of the one or more axial free wings are designed to face constantly same direction when the multirotor flying, and the attack angles of the one or more axial free wings are designed to be changed relatively to the chassis due to flow of air over the one or more axial free wings.
