Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the aerial vehicle is equipped with computational and hardware resources for docking, then the docking function can be performed, but the weight of the aerial vehicle increases
Solution Approach 1:
The docking control system is extracted from the aerial vehicle and relocated to the docking station. The docking station now contains the computational and hardware resources needed for docking, while the aerial vehicle only needs simple magnetic docking components, significantly reducing its weight
Solution Approach 2:
A magnetic docking mechanism serves as an intermediary between the aerial vehicle and the docking station. The magnetic attraction force enables automatic docking without requiring complex sensors or control systems on the aerial vehicle, resolving the contradiction between docking reliability and vehicle weight
2Measurement precision
If the aerial vehicle carries docking hardware and computational resources, then accurate docking can be achieved, but the device complexity increases
Solution Approach 1:
Complex docking control electronics, sensors, and computational resources are extracted from the aerial vehicle and placed in the docking station. The aerial vehicle is simplified to carry only basic magnetic docking components and power source
Solution Approach 2:
The docking station performs all computational and control functions autonomously to guide the aerial vehicle into the correct docking position. The aerial vehicle simply responds to magnetic attraction forces, eliminating the need for complex onboard docking systems
