Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for accommodating multiple drones at once has led to a higher likelihood of collisions due to limited space, necessitating a system that can prevent collisions and ensure safe transportation and landing of drones.
Innovation Solution
A drone equipped with an anti-torque compensation method using an anti-torque compensator, which includes a propulsor, a motor, and a torsion spring, that stabilizes the drone's posture and slows down its fall speed to prevent tumbling and allow time for parachute or airbag deployment, maintaining hovering and enabling a soft landing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple drones are accommodated and transported at once, then transportation efficiency is improved, but the risk of collision between drones increases
Solution Approach 1:
The patent introduces an anti-torque compensator as an intermediary device between the propulsor and the drone body. This compensator actively counteracts unwanted torque effects that cause tumbling during failure scenarios, thereby preventing collisions with other drones while maintaining close formation during transportation.
Solution Approach 2:
The anti-torque compensator enables the drone to self-correct its posture and stabilize itself during failure conditions without external intervention. By automatically compensating for torque imbalances, the drone protects itself from tumbling and potential collision, enabling safe close-formation transportation.
2Reliability
If the drone falls due to propulsor failure, then loss of control occurs, but tumbling increases fall speed and reduces safety
Solution Approach 1:
The anti-torque compensator applies preliminary counteracting torque before the drone can tumble during failure. By continuously monitoring and compensating for torque imbalances, the system prevents the development of tumbling motion that would otherwise accelerate the fall and reduce safety margins.
Solution Approach 2:
The compensator system prepares for potential failure by maintaining active torque compensation readiness. During actual failure, this pre-positioned compensation capability immediately counteracts destabilizing forces, effectively cushioning against the harmful effects of sudden torque loss and preventing catastrophic tumbling.
3Device complexity
If traditional anti-torque methods are used, then simplicity is maintained, but posture stability during failure is insufficient
Solution Approach 1:
The patent transitions from static anti-torque mechanisms to a dynamic compensator system that actively adjusts torque compensation in real-time. This dynamic approach allows the system to adapt to varying failure conditions and maintain posture stability across different scenarios, overcoming the limitations of fixed simple mechanisms.
Solution Approach 2:
The anti-torque compensator incorporates feedback control to continuously monitor drone posture and torque conditions. This feedback mechanism enables real-time adjustments to compensation forces, significantly improving posture stability during failure while maintaining reasonable system complexity through efficient control algorithms.
