Solution Overview
Problem
Existing multicopters face challenges in precise positioning and control, especially for non-professional pilots, with current techniques requiring tilting movements that lead to rough landings and difficulty in navigating small spaces or windy conditions.
Innovation Solution
The multicopter is equipped with additional drive devices, such as propellers or airflow systems, that allow for horizontal movement without tilting, using control airflows generated by existing propellers or a compressor, enabling precise positioning and smooth navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional drive devices are added to enable horizontal movement without tilting, then positioning precision and ease of operation are improved, but device complexity increases
Solution Approach 1:
The patent applies multi-functionality by making the main propellers serve dual purposes: primary lift generation and secondary horizontal thrust generation through variable pitch control. This eliminates the need for separate dedicated horizontal propulsion devices, thereby improving positioning precision without proportionally increasing device complexity.
Solution Approach 2:
The patent merges the functions of vertical lift and horizontal propulsion into a single integrated propulsion system. By combining the tilt mechanism and variable pitch control into the existing multicopter structure, it achieves precise horizontal positioning without requiring entirely separate drive systems, thus balancing positioning precision with acceptable device complexity.
2Speed
If tilt mechanisms are used for horizontal movement, then mobility is improved, but ease of operation deteriorates due to rough landings and difficulty in small spaces
Solution Approach 1:
The patent applies dynamics by implementing variable pitch control that allows real-time adjustment of propeller blade angles. This enables the multicopter to generate horizontal thrust without tilting the entire vehicle body, maintaining stable landing posture and improving ease of operation in confined spaces while preserving mobility through dynamic thrust vectoring.
Solution Approach 2:
The patent substitutes the traditional mechanical tilt-based horizontal movement system with a blade pitch-controlled thrust vectoring system. This replacement eliminates the need for physical tilting mechanisms that cause rough landings, while achieving the same mobility effect through aerodynamic control, thereby improving ease of operation without sacrificing speed.
3Measurement precision
If variable pitch control is implemented for precise positioning, then positioning precision is improved, but device complexity and control system complexity increase
Solution Approach 1:
The patent applies multi-functionality by enabling the existing propeller pitch control mechanism to serve multiple functions: primary lift adjustment and secondary horizontal thrust generation. This unified control approach achieves precise positioning without requiring entirely separate control systems, thereby limiting the increase in control system complexity while improving positioning precision.
4Ease of operation
If separate auxiliary propellers are added for horizontal control, then ease of operation is improved, but device complexity and quantity of components increase
Solution Approach 1:
The patent applies multi-functionality by making the main propellers perform both vertical lift and horizontal propulsion functions through variable pitch control. This eliminates the need for separate auxiliary propellers, maintaining ease of operation through integrated control while reducing the total quantity of components required in the system.
