Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor is provided for each solar module to enable individual tracking, then the tracking precision and adaptability are improved, but the production cost and device complexity increase significantly
Solution Approach 1:
The patent merges multiple individual tracking mechanisms into a single group-level tracking mechanism. Multiple solar modules are arranged in rows to form groups, and each group is rotated simultaneously by a single linear actuator rather than requiring individual motors for each module. This consolidation reduces the number of driving components while maintaining the ability to track the sun's movement across the sky.
Solution Approach 2:
The linear actuator serves as a universal driving mechanism for entire groups of solar modules. Instead of specialized motors for each module, a single linear actuator performs the tracking function for multiple modules simultaneously, making the system more economical and easier to maintain while achieving the essential tracking capability.
2Ease of manufacture
If solar modules are arranged parallel to the ground for simple installation, then the ease of manufacture is improved, but the photovoltaic efficiency decreases during winter when sun altitude is lower
Solution Approach 1:
The patent transitions from a static parallel arrangement to a dynamic adjustable configuration. Solar modules are arranged in rows that can be rotated together as a group, allowing the inclination angle to be adjusted according to seasonal changes in sun altitude. This dynamic adjustment optimizes light reception during different times of the year while maintaining structural simplicity.
