Solution Overview
Problem
Concentrated Solar Power (CSP) systems face challenges in efficiently transferring force to solar mirror frames and maintaining alignment, as well as in effectively cleaning mirrors without using water, particularly in arid regions where water is a limited resource.
Innovation Solution
The development of torque plates with nodes and strut end pieces that allow for rotational alignment and attachment, combined with a method for cleaning mirrors using a blower assembly that blows air to remove dust and sand, addresses these issues by enhancing structural integrity and reducing water usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional connection methods are used for solar mirror frames, then assembly is simpler, but structural integrity and alignment precision deteriorate
Solution Approach 1:
The connection system is divided into separate functional components: torque plates for force transfer, nodes for structural connection, and alignment features for positioning. This segmentation allows each component to be optimized for its specific function while maintaining overall structural integrity.
Solution Approach 2:
The patent employs nested connection elements where nodes are integrated into frame members, and torque plates are attached to nodes. This nesting approach consolidates multiple connection functions into hierarchical structures, improving strength without proportionally increasing overall complexity.
2Productivity
If water-based cleaning methods are used for mirrors, then cleaning effectiveness is higher, but water consumption increases which is problematic in arid regions
Solution Approach 1:
The patent replaces water-based cleaning mechanisms with air-based pneumatic cleaning systems. Compressed air is used to blow dust and debris off mirror surfaces, eliminating water consumption while maintaining cleaning effectiveness through aerodynamic force.
Solution Approach 2:
The cleaning system utilizes pneumatic principles by employing compressed air flow to remove contaminants from mirror surfaces. This pneumatic approach provides effective cleaning without the need for liquid water, making it suitable for arid environments where water is scarce.
3Strength
If torque plates with nodes are used for force transfer, then structural efficiency improves, but manufacturing and assembly complexity increases
Solution Approach 1:
The patent optimizes torque plate parameters such as thickness, hole patterns, and material properties to achieve efficient force transfer. By carefully selecting and adjusting these parameters, the design achieves high structural efficiency while maintaining manufacturability through standard fabrication processes.
Solution Approach 2:
The nodes and torque plates are designed with self-aligning features and integrated connection elements that facilitate automatic positioning during assembly. This self-service approach reduces the skill level and time required for assembly, partially offsetting the increased manufacturing complexity.
