Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If larger power devices are installed to meet vertical take-off and landing requirements, then power output is improved, but structural integrity deteriorates
Solution Approach 1:
The power system is segmented into a modular integrated assembly comprising the motor module, ESC module, and fixing structure as a unified unit. This segmentation allows the power system to be designed as a compact module that delivers high power output while maintaining structural integrity through the integrated fixing structure with barrel body and extension part.
2Power
If more power devices are installed, then power capacity is improved, but installation space requirements increase
Solution Approach 1:
The motor module and ESC module are merged into a single integrated power module assembly, eliminating the need for separate mounting spaces. The fixing structure with barrel body and extension part combines multiple functions (mounting, positioning, and structural support) into one component, significantly reducing the overall installation space required while maintaining high power capacity.
3Area of stationary object
If power devices are installed in limited space, then space utilization is improved, but structural damage risk increases
Solution Approach 1:
The fixing structure is designed in advance with a barrel body and extension part configuration that pre-establishes optimal force distribution pathways. The extension part extending radially outward from the barrel body creates predetermined stress relief zones, preventing structural damage before it occurs during operation.
4Productivity
If modular assembly is implemented, then production efficiency is improved, but assembly complexity increases
Solution Approach 1:
The power system is divided into distinct modular components (motor module, ESC module, fixing structure) that can be manufactured separately and assembled efficiently. The fixing structure with its barrel body and extension part serves as a standardized interface component, simplifying the assembly process despite the modular nature of the system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The combined power module reduces structural damage, enhances production efficiency, and lowers costs by forming an independent module with uniform force distribution and enhanced heat dissipation.
Implementation Method 1
it further comprises a damping pad, the damping pad is located between the motor module and the ESC module, providing a damping function for the motor module during operation
Implementation Method 2
it can also conduct part of the heat from the bearing sleeve to the arm to increase heat dissipation
