Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drone safety systems are inadequate for small, lightweight drones that are easily influenced by wind and may not have access to specific facilities like airports, making emergency situations challenging.
Innovation Solution
A circuit and method that includes a report unit to provide action-allowable time information to a base station, which then instructs a drone on actions based on defined danger levels in an emergency, using a map to guide safe landing or operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drones use existing airport-based emergency systems, then safety infrastructure is available, but drones cannot access specific facilities like airports making emergency situations challenging
Solution Approach 1:
The drone performs self-diagnosis of its own state (battery level, motor temperature, blade status) and autonomously determines emergency actions without requiring external airport infrastructure. The on-board controller enables the drone to independently assess its condition and execute appropriate emergency responses.
Solution Approach 2:
The system transitions from ground-based airport emergency infrastructure to aerial emergency handling capabilities. By defining danger levels for different spatial locations and enabling vertical landing options, the system creates a three-dimensional emergency response approach that eliminates the need for traditional airport facilities.
2Ease of operation
If drones are lightweight for easy operation, then ease of operation improves, but they are easily influenced by wind and may encounter emergency situations
Solution Approach 1:
The on-board controller continuously monitors drone state parameters (battery charge, motor temperature, blade status) and environmental conditions, providing real-time feedback to the control unit. This enables the lightweight drone to automatically adjust its operations and execute emergency actions when abnormal conditions are detected, ensuring safety without compromising ease of operation.
Solution Approach 2:
The system performs preliminary diagnosis of potential emergency conditions by monitoring battery levels, motor temperatures, and blade status before critical failures occur. Action-allowable time information is calculated in advance, enabling the drone to take preventive measures or execute emergency procedures before situations become critical.
3Speed
If autonomous decision-making is implemented for emergency actions, then response speed improves, but complexity of control increases
Solution Approach 1:
The control system segments emergency responses into distinct danger levels (first through fourth levels) with specific predefined actions for each level. This segmentation simplifies the decision-making process by providing a clear hierarchical structure, where the controller systematically evaluates conditions and executes corresponding actions without requiring complex autonomous judgment.

AI summary
Provided is a circuit including a report unit that reports action-allowable time information regarding an action-allowable time to a base station, and an action control unit that controls an action of a moving object on the basis of an action instruction. The action instruction is decided on the basis of the reported action-allowable time information and notified of by the base station. The action control unit further controls the action with reference to a map in which a danger level for each place is defined in an emergency situation.
