Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a main rotor and tail rotor system is used in conventional helicopters, then torque compensation and control are achieved, but device complexity and cost increase significantly

Engineering Contradiction:
Improvetorque compensation capabilityVSAvoid rotor system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the tail rotor component entirely from the helicopter system. Instead of using a separate tail rotor for torque compensation, the invention uses the main rotor blades themselves to generate both lift and torque compensation forces through asymmetric pitch control and cyclic variation, eliminating the need for a dedicated tail rotor assembly

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The main rotor blades are designed to perform multiple functions simultaneously: generating lift, providing torque compensation, and enabling directional control. By varying the pitch angle cyclically during rotation, the same blades that produce upward thrust also generate horizontal force components that counteract torque and control yaw, making the rotor system universally capable of all primary flight functions

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If a main rotor and tail rotor system is used in conventional helicopters, then torque compensation and control are achieved, but manufacturing cost increases

Engineering Contradiction:
Improvetorque compensation capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

By removing the tail rotor assembly entirely, the patent eliminates multiple expensive components including the tail rotor blades, hub, mounting structure, and associated control linkages. This extraction of unnecessary components directly reduces material costs, assembly complexity, and maintenance requirements while achieving the same torque compensation function through the main rotor system

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The main rotor blades are designed to perform multiple functions simultaneously: generating lift, providing torque compensation, and enabling directional control. By varying the pitch angle cyclically during rotation, the same blades that produce upward thrust also generate horizontal force components that counteract torque and control yaw, making the rotor system universally capable of all primary flight functions

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If conventional helicopter designs are used, then stable flight is achieved, but adaptability to different applications is limited

Engineering Contradiction:
Improveflight stabilityVSAvoidapplication versatility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent employs dynamic pitch control where the blade pitch angles are continuously varied during rotation rather than remaining fixed. This allows the rotor system to adapt its aerodynamic characteristics in real-time, enabling stable flight while also providing the flexibility to adjust performance for different applications, loads, and environmental conditions

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The main rotor blades are designed to perform multiple functions simultaneously: generating lift, providing torque compensation, and enabling directional control. By varying the pitch angle cyclically during rotation, the same blades that produce upward thrust also generate horizontal force components that counteract torque and control yaw, making the rotor system universally capable of all primary flight functions

Inventive Principle:
Principle #6Universality (Multi-functionality)
