Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed position installation without moving mechanism is used, then capital and operating costs are reduced and endurance in rugged conditions is increased, but power generation efficiency is compromised due to inability to track optimal solar positions
Solution Approach 1:
The patent applies the dynamics principle by implementing a moving mechanism that enables solar panels to transition between fixed and movable states. The system includes a carriage that can move along rails to adjust panel orientation and position, allowing the installation to dynamically track solar positions while maintaining structural stability through controlled movement rather than continuous adjustment
2Ease of operation
If conventional solar power systems are deployed in off-grid locations, then power supply is provided, but operator effort and complexity increase due to manual operation requirements and diverse skill set needs
Solution Approach 1:
The patent applies self-service principle through automated control systems that manage solar panel positioning, power generation optimization, and system monitoring without requiring manual intervention. The microcontroller-based system automatically adjusts panel orientations, monitors power output, and manages battery charging/discharging cycles, eliminating the need for operators with diverse technical skill sets
Solution Approach 2:
The system incorporates feedback mechanisms through sensors and monitoring circuits that continuously track solar irradiance, panel position, power output, and battery charge levels. This feedback enables the control system to automatically optimize performance by adjusting panel orientations and power distribution based on real-time conditions, reducing operational complexity
3Ease of operation
If solar panels are manually deployed by operators, then deployment is achieved, but force requirements exceed acceptable limits for ease of operation
Solution Approach 1:
The patent applies counterweight principle through the carriage system that supports solar panels during deployment and positioning. The carriage mechanism distributes the weight of large-format solar panels across multiple support points and uses mechanical advantage through rails and guides, reducing the force required by operators to maneuver panels into position
Solution Approach 2:
The patent introduces a carriage as an intermediary device between the solar panels and the ground/ mounting structure. This intermediary component facilitates easy panel installation by providing a movable platform that can be positioned and secured with minimal force, acting as a mediator that simplifies the deployment process while supporting panel weight during installation
