Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cement foundations are used to secure supporting structures, then system stability is improved, but installation complexity and cost increase, and removal becomes difficult
Solution Approach 1:
The invention extracts and eliminates the cement foundation component from the supporting structure system. Instead of using cement foundations, the patent employs adjustable supporting structures that can be directly installed on the installation surface, thereby simplifying the overall system while maintaining stability through adjustable positioning and rigid connection mechanisms.
Solution Approach 2:
The supporting structures incorporate adjustable parameters including height, angle, and positioning. These adjustable parameters allow the structures to adapt to various installation surfaces and achieve optimal stability without requiring complex cement foundations. The adjustability enables precise alignment and secure installation through mechanical means rather than chemical bonding.
2Manufacturing precision
If adjustable supporting structures are used to correct positioning errors, then installation accuracy is improved, but device complexity increases
Solution Approach 1:
The supporting structures incorporate dynamic adjustment capabilities that allow positioning corrections after installation. The structures can be adjusted in height, angle, and lateral position to compensate for alignment errors. These adjustments are achieved through simple mechanical mechanisms rather than complex systems, maintaining ease of use while improving precision.
Solution Approach 2:
The invention incorporates preliminary adjustment features in the supporting structures that enable correction of positioning errors before final assembly. The adjustable components allow installers to pre-position elements accurately, and subsequent adjustments can be made to fine-tune alignment without requiring complex disassembly or specialized equipment.
3Ease of manufacture
If simple supporting structures without cement foundations are used, then ease of removal is improved, but positioning accuracy deteriorates
Solution Approach 1:
The supporting structures incorporate dynamic adjustment capabilities that allow positioning corrections after installation. The structures can be adjusted in height, angle, and lateral position to compensate for alignment errors. These adjustments are achieved through simple mechanical mechanisms rather than complex systems, maintaining ease of use while improving precision.
Solution Approach 2:
The supporting structures are designed to be self-aligning and self-adjusting through their inherent mechanical features. The structures include built-in adjustment mechanisms that enable installers to achieve accurate positioning without requiring external equipment or complex procedures. The design allows the structures to compensate for installation surface irregularities autonomously.

AI summary
A supporting device for photovoltaic panels in tracking photovoltaic systems comprises at least one supporting upright extending substantially longitudinally and extending from an installation surface of the system, a fixing plate for the photovoltaic panel and a connecting member between the upright and the plate that is supported on the upright so as to keep the panels spaced from the installation surface during operation of the system, and comprises a rolling member capable of connecting the fixing plate in a rotary manner about a tracking axis and further to enable the fixing plate to rotate at least in a limited manner about a first adjustment axis substantially orthogonal to the tracking axis and the direction of longitudinal extension of the upright.
