Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aerial vehicle systems face challenges in efficiently lifting and maneuvering payloads, particularly when payloads vary in size, as they require multiple aircraft, which are costly, risky, and not scalable due to the need for coordinated operation by skilled pilots or operators.
Innovation Solution

Engineering Contradiction Analysis
1Force
If multiple aircraft are used to lift a payload larger than a single aircraft's capability, then the lifting capability is improved, but the operational cost and complexity increase significantly
Solution Approach 1:
The payload is divided into multiple segments that can be independently lifted by individual aircraft. Each aircraft handles a portion of the total payload, eliminating the need for complex coordination of multiple aircraft around a single large payload. The segments are then transported to the destination and reassembled.
Solution Approach 2:
A centralized control system acts as an intermediary that coordinates the operations of multiple aircraft. This control system manages thrust adjustments, positioning, and synchronization of all aircraft in the formation, reducing the coordination complexity that would otherwise be borne by multiple pilots or operators.
2Ease of operation
If multiple aircraft with operators are used to maneuver a payload, then the maneuvering capability is improved, but the operational cost increases due to multiple operators
Solution Approach 1:
The aircraft are equipped with autonomous navigation and control systems that enable them to maneuver the payload without human operators on board or directly controlling each aircraft. The system automatically adjusts thrust, position, and orientation based on pre-programmed instructions or real-time sensor data, eliminating the need for multiple operators.
Solution Approach 2:
Manual control systems operated by human pilots are replaced with automated flight control systems. These systems use sensors, processors, and actuators to automatically manage aircraft behavior, substituting mechanical human operation with an automated control architecture that can coordinate multiple aircraft more efficiently.
3Productivity
If aircraft operate in close proximity to lift a single payload, then the lifting efficiency is improved, but the safety risk increases due to coordinated operation requirements
Solution Approach 1:
The aircraft are equipped with sensors that continuously monitor the position, velocity, and orientation of each aircraft and the payload. This data is fed back to the control system in real-time, allowing for automatic adjustments to maintain safe separation distances and proper formation geometry, thereby reducing safety risks while maintaining lifting efficiency.
Solution Approach 2:
The control system incorporates safety margins and buffer zones in the coordination algorithms. Before potential conflict situations arise, the system pre-adjusts aircraft positions and velocities to maintain safe separation. Emergency protocols are pre-programmed to automatically activate if anomalies are detected, providing a cushion against safety risks.
4Quantity of substance
If a single aircraft is used to lift a payload, then the operational cost is reduced, but the maximum payload size is limited by the aircraft's lifting capability
Solution Approach 1:
Large payloads that exceed the capability of a single aircraft are divided into smaller segments that can each be handled by standard-capacity aircraft. This segmentation allows the use of more readily available, less expensive aircraft while still achieving the goal of transporting large overall payloads through coordinated multi-aircraft operations.
Solution Approach 2:
The system is designed to accommodate various payload sizes and configurations using the same basic multi-aircraft coordination approach. By standardizing the coordination protocol and control architecture, the system can adapt to different payload requirements without requiring specialized aircraft or procedures, enhancing versatility.
