Aircraft Power Unit Modular Assembly for Tight Installation Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft power units are limited by installation space, particularly in vertical takeoff and landing aircraft, necessitating a highly integrated design that fits within the available space while maintaining structural integrity, and existing assembly methods are not cost-effective.
Innovation Solution
A modular power unit design comprising a motor module, ESC module, and fixing connection rods that serially connect the modules and secure the unit to the aircraft body, using threaded and bearing portions for assembly and connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the power unit is designed to be highly integrated to fit limited installation space, then the installation space requirement is reduced, but the manufacturing and assembly complexity increases
Solution Approach 1:
The power unit is divided into separate motor module and ESC module that can be manufactured independently and then assembled together using fixing connection rods, reducing overall assembly complexity while maintaining compact integration
Solution Approach 2:
The fixing connection rods serve multiple functions: they connect the motor module to the ESC module, provide structural support, and enable modular assembly, thereby reducing the need for additional specialized components
2Ease of manufacture
If traditional non-modular assembly methods are used, then structural integrity is maintained, but production cost increases
Solution Approach 1:
The power unit is segmented into modular components (motor module, ESC module) that can be manufactured separately using standardized processes, reducing production costs while maintaining structural integrity through proper connection design
Solution Approach 2:
The motor module and ESC module are pre-assembled and tested as separate units before final integration, allowing for quality control and error correction at earlier stages, thereby reducing overall production costs while ensuring structural reliability
