Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solar panels are mounted on roofs in fixed positions, then installation space is utilized, but aesthetic appearance deteriorates and energy output is limited
Solution Approach 1:
The solar tracking system is divided into separate modular components including individual tracking assemblies that can be independently positioned. This allows the solar panels to be segmented and arranged in configurations that maintain aesthetic appearance while enabling tracking functionality for increased energy output
Solution Approach 2:
The system transitions from fixed two-dimensional roof mounting to three-dimensional spatial positioning with tracking capability. Panels can move in multiple dimensions to follow the sun's path, dramatically increasing energy capture while being positioned to minimize visual impact on the building structure
2Productivity
If large arrays of solar panels are deployed, then energy generation increases, but space requirements increase
Solution Approach 1:
The solar tracking system employs dynamic positioning mechanisms that allow panels to move and reposition themselves throughout the day. This dynamic capability enables a smaller array to capture the same amount of energy that would require a much larger fixed array, reducing overall space requirements while maintaining high energy generation
Solution Approach 2:
The system changes the operational parameters of the solar panels by enabling continuous adjustment of panel orientation and position. This parameter change from fixed to variable positioning maximizes energy capture per unit area, allowing high energy generation with reduced space requirements
3Productivity
If conventional solar systems are installed, then energy production is achieved, but system cost increases
Solution Approach 1:
The solar tracking system is designed to be self-regulating and autonomous, automatically adjusting panel positions without requiring complex control systems or frequent maintenance. This self-service capability reduces manufacturing costs and operational expenses while maintaining high energy production levels

AI summary
A free-standing solar tracker comprises a base, a support frame, a panel assembly comprising one or more solar panels, and an actuator to rotate the panel assembly to track the movement of the sun. The solar tracker is designed to be free-standing and requires no foundation. When the solar tracker is deployed, the base forms a pan to contain a ballast material for holding the base in place. The base of the solar tracker is designed to serve as a “suitcase” to contain most of the components of the solar tracker, making it easier to transport the solar tracker 10 to a location where the solar tracker is installed.
