Solution Overview
Problem
Solar tracking systems face issues with compressive forces and rotational loads on torque tubes, leading to deformation and slippage, which are not effectively addressed by existing damping systems that increase complexity and reduce density efficiency.
Innovation Solution
The introduction of support devices that enhance the connection surface area between the torque tube and attachment structures, distributing compressive forces and reducing rotational loads without the need for additional damping systems, thereby minimizing complexity and material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional damping systems are introduced to compensate for rotational loads, then the reliability of the connection points is improved, but the device complexity increases and density efficiency decreases
Solution Approach 1:
The support device segments the connection interface by introducing a multi-surface attachment structure that divides the force distribution across multiple discrete contact points (first surface, second surface, third surface) on the torque tube, rather than relying on a single damping component
Solution Approach 2:
The attachment structure utilizes three-dimensional spatial distribution of contact surfaces around the torque tube perimeter, engaging forces in multiple directions and planes simultaneously, thereby improving connection reliability without adding axial length or requiring additional damping components
2Reliability
If additional damping systems are introduced to compensate for rotational loads, then the reliability of the connection points is improved, but the area utilization decreases due to dead spaces
Solution Approach 1:
The attachment structure serves multiple functions simultaneously: it provides structural support, distributes compressive forces, resists rotational loads, and maintains connection stability—all through a single integrated component that engages with the torque tube's outer periphery, eliminating the need for separate damping systems and their associated dead spaces
3Strength
If tube clamps are over-torqued to secure connections, then the connection strength is improved, but the torque tube deformation increases
Solution Approach 1:
The support device introduces localized structural features (flanges, bracing elements) at specific positions around the torque tube perimeter to reinforce areas subject to highest stress concentrations, allowing the torque tube to maintain its overall shape while still achieving strong connections at critical points
4Stress or pressure
If support devices with enhanced connection surface area are used, then the compressive force distribution is improved, but the device complexity increases
Solution Approach 1:
The support device merges the functions of multiple structural elements (flanges for force distribution, bracing for rotational resistance, mounting features for attachment) into a single integrated component that engages with the torque tube, achieving improved stress distribution without proportionally increasing overall system complexity

AI summary
A support device may include a body that includes a surface. The surface may be configured to physically engage with at least a first surface section of a torque tube. In addition, at least a second surface section of the torque tube may be configured to engage with a surface of an attachment structure. The body and the attachment structure may together define an aperture configured to receive the torque tube.
