Flying Body Obstacle Avoidance via Lift Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flying objects lack the ability to automatically detect and avoid obstacles or adjust to wind direction changes, leading to potential collisions and unstable flight, especially when unintentionally brought close to obstacles or subjected to sudden wind direction changes.
Innovation Solution
Incorporating an obstacle detecting unit, wind direction detecting unit, and a control unit that operates a steering mechanism, such as brake cords, to deploy a lift generating member like a paraglider, allowing the flying object to autonomously avoid collisions and adjust its flight path based on detected obstacles and wind conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional flying object is equipped with a deployment device for parachutes or paragliders, then the flying object can be decelerated during falling, but the flying object cannot automatically detect obstacles or wind direction changes to avoid collision or adjust flight path
Solution Approach 1:
The flying object is equipped with obstacle detecting units and wind direction detecting units that enable it to autonomously detect environmental conditions and automatically control the deployment of lift-generating members without external intervention, making the system self-service in terms of safety and navigation
Solution Approach 2:
The control unit receives detection signals from obstacle detecting units and wind direction detecting units in real-time, and based on this feedback information, automatically adjusts the deployment state of lift-generating members to optimize flight performance and avoid obstacles
2Object-affected harmful factors
If the flying object deploys a lift generating member to decelerate during falling, then collision impact can be mitigated, but the flying object cannot instantly respond to sudden obstacles at low altitude
Solution Approach 1:
The control unit is configured to automatically control the deployment of lift-generating members based on detection signals before the flying object actually collides with obstacles, enabling preliminary protective action to mitigate collision impact
Solution Approach 2:
The system detects obstacles and wind conditions in advance and takes counteracting measures by deploying or adjusting lift-generating members to prevent harmful effects such as collision or unstable flight
3Ease of operation
If the flying object uses a brake cord steering mechanism, then the lift generating member can be steered, but the flying object cannot automatically adjust steering based on wind direction changes
Solution Approach 1:
The wind direction detecting unit automatically detects wind direction changes and the control unit automatically adjusts the brake cord tension to steer the lift-generating member in the appropriate direction, making the steering system self-service without manual intervention
Solution Approach 2:
The control unit continuously receives wind direction information from the wind direction detecting unit and uses this feedback to automatically adjust the brake cord steering mechanism, creating a closed-loop automatic wind adaptation system

AI summary
To provide a flying object including a lift generating member deployment device that makes it easier than before to automatically avoid collision with an obstacle. A flying object 30 includes an obstacle detecting unit 5, a control unit 6, a battery 7, a storage unit 8 that stores information transmitted from the control unit 6, a transmitting/receiving unit 9 that receives an operation signal from a controller 40 and transmits information regarding the flying object 30 to the controller 40, and others. The obstacle detecting unit 5 is to detect the altitude of the flying object 30 and outputs an altitude detection signal, which represents the detected altitude information, to the control unit 6. In addition, upon detecting an obstacle present within a predetermined distance, the obstacle detecting unit 5 outputs an obstacle detection signal to the control unit 6, detects the distance between the flying object body 31 and the obstacle, and outputs a distance detection signal, which represents the detected distance information, to the control unit 6. The control unit 6 determines whether or not to actuate left and right brake cord pulling devices 10 in accordance with the signal received from the obstacle detecting unit 5.
