Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple connection between drive motor rotation shaft and solar panel is used, then device complexity is reduced, but reliability deteriorates due to overload and damage from external forces
Solution Approach 1:
The patent introduces a gear assembly as an intermediary mechanism between the drive motor and solar panel. This gear assembly includes a drive gear connected to the motor shaft and a driven gear connected to the panel, with a gear shaft connecting them. This intermediary structure protects against direct overload transmission while maintaining the simple overall design philosophy.
2Reliability
If gear assembly is installed between drive motor and solar panel, then reliability is improved, but device complexity increases and backlash occurs
Solution Approach 1:
The gear assembly is segmented into distinct functional components: drive gear, driven gear, gear shaft, and gear housing. This segmentation allows each component to be optimized independently while maintaining overall simplicity. The modular structure makes the complex gear mechanism easier to manufacture, assemble, and maintain.
3Device complexity
If conventional fixed installation is used, then device complexity is reduced, but productivity deteriorates due to low solar power generation efficiency
Solution Approach 1:
The patent transforms the static fixed installation into a dynamic rotating system. The solar panel can rotate around the pole axis to track the sun's movement, maximizing sunlight capture throughout the day. This dynamic capability significantly improves power generation efficiency while the simple pole-and-panel structure keeps device complexity low.
4Device complexity
If solar panel is placed on top of pole with simple rotation connection, then device complexity is reduced, but stability deteriorates due to shaking from wind and backlash
Solution Approach 1:
The gear assembly acts as a mechanical intermediary that provides stable power transmission between the motor and panel. The meshing gears transmit rotational force smoothly, reducing vibrations and shaking caused by direct connections. This intermediary mechanism enhances stability while maintaining rotational capability.
