Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If aerial drones are used for inspection, then operational flexibility is improved, but risk of damage to the inspected object increases
Solution Approach 1:
The patent introduces an intermediary mechanism (adhesion system with thrust vectors) between the drone and the inspected object. This allows the drone to maintain proximity for detailed inspection while preventing direct contact that could cause damage, resolving the contradiction between operational flexibility and damage risk
Solution Approach 2:
The thrust system generates counteracting forces to balance gravitational pull and control the drone's position relative to the inspected object. By applying thrust in opposite directions, the system maintains safe distances while preserving inspection capability
2Reliability
If mechanical propulsion system is used to traverse multi-oriented surfaces, then adhesion capability is improved, but device complexity increases
Solution Approach 1:
The mechanical propulsion system serves multiple functions: it provides thrust for movement, generates adhesion forces through controlled contact, and enables traversal across varying surface orientations. This multi-functionality reduces the need for separate specialized systems, managing complexity while improving adhesion
3Ease of operation
If thrust system is used to oppose gravitational force, then control over multi-oriented surfaces is improved, but energy consumption increases
Solution Approach 1:
The thrust system dynamically adjusts its force magnitude and direction based on real-time surface orientation and gravitational requirements. By continuously adapting thrust parameters rather than maintaining constant maximum output, the system improves control while reducing unnecessary energy consumption
