Multi-Axis Reflector Assembly for Solar Tower Tracking Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solar power tower systems lack advanced tracking and control systems that allow for multi-axis rotation of reflectors, which is necessary for efficient energy capture and storage, unlike parabolic trough reflectors that only rotate along a single axis.
Innovation Solution
A solar heating apparatus with a multi-axis reflector system that includes longitudinally and laterally extending shafts with two-axis bearings, rotating members, and motors to enable simultaneous rotation about multiple axes, allowing for precise control and positioning of reflectors to concentrate solar radiation effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single-axis rotation is used for reflectors, then device complexity is reduced, but energy capture efficiency deteriorates
Solution Approach 1:
The patent transitions from single-axis to multi-axis rotation by adding a second rotational dimension. The reflector assembly includes a first rotation mechanism for azimuthal rotation and a second rotation mechanism for elevation rotation, enabling the reflector to track the sun in both horizontal and vertical planes simultaneously, thereby capturing solar energy more efficiently throughout the day
2Productivity
If multi-axis rotation is implemented, then energy capture efficiency is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple rotation mechanisms into a unified reflector assembly. The first and second rotation mechanisms are integrated with the reflector assembly such that both rotational movements are coordinated to position the reflector optimally. This merging approach manages complexity by creating a coordinated system rather than separate independent mechanisms
3Device complexity
If reflectors are fixed in position, then device complexity is minimized, but adaptability to changing solar positions deteriorates
Solution Approach 1:
The patent transforms the reflector from a fixed position to a dynamic positioning system. The reflector assembly incorporates both azimuthal and elevation rotation mechanisms that allow continuous adjustment of the reflector's orientation. This dynamic capability enables the system to adapt to the sun's changing position throughout the day and across different seasons, maximizing solar energy capture

Data Source
AI summary
The solar heating apparatus includes driven and controllable reflectors for concentrating solar radiation on a solar tower or the like. Each of the reflectors provided in an array of reflectors is selectively driven to rotate about multiple axes of rotation. A plurality of groupings of optical reflectors, such as mirrors or the like, are mounted about a single, common longitudinally extending shaft, providing simultaneous rotation of the optical reflectors about a longitudinal axis. Through a two-axis bearing associated with each grouping of optical reflectors, the optical reflectors are also mounted on a laterally extending shaft associated with each individual reflector grouping. The laterally extending shafts are linked, each to the other, by a continuous belt or the like, providing selective simultaneous rotation of the optical reflectors about the lateral axis in addition to the simultaneous rotation about the longitudinal axis.
