Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mechanical attachment systems are used for PV panels, then the panels can be securely attached to support structures, but the locking and unlocking process becomes complex and time-consuming
Solution Approach 1:
The patent replaces complex mechanical locking mechanisms with a magnetic attachment system. The magnetic support structure uses magnetic fields to securely hold PV panels, eliminating the need for complex mechanical locks, bolts, or clips. This substitution simplifies the attachment mechanism while maintaining secure fastening, allowing for easy installation and removal by simply bringing the panel near the magnetic support structure.
Solution Approach 2:
The patent changes the attachment parameter from mechanical interlocking to magnetic field interaction. By utilizing magnetic field strength as the attachment parameter, the system achieves secure holding without complex mechanical structures. The magnetic force can be easily controlled by adjusting the magnetic field parameters, enabling simple on/off attachment without complex operational steps.
2Reliability
If PV panels are permanently fixed to support structures, then stability is maximized, but maintenance and replacement become difficult
Solution Approach 1:
The patent creates a dynamic attachment system where the magnetic hold strength can be adjusted or deactivated. The magnetic support structure allows panels to be securely held during operation (maintaining reliability) but can easily release when needed for maintenance (improving ease of repair). This dynamic capability enables quick panel removal and reinstallation without permanent fixation, facilitating easy maintenance and replacement while ensuring operational stability.
3Ease of manufacture
If simple attachment mechanisms are used for PV panels, then installation is quick and easy, but the panels may not remain stable under environmental conditions
Solution Approach 1:
The patent replaces simple but inadequate mechanical attachments with a magnetic field-based system. The magnetic support structure provides strong, stable holding force that can securely resist environmental forces like wind and vibration, while maintaining the simplicity and speed of installation. The magnetic field naturally adapts to panel positioning, providing stable attachment without complex alignment procedures or multiple fastening steps.

AI summary
Apparatuses for locking PV panels to support structures, e.g., support beams. The support beams may be designed and built with corresponding connection elements, e.g., slots and tabs, which may be used to enable locking and unlocking of the PV panels on the support beams. Once in place, a ferromagnetic flap may be put into an engaged position, thereby closing and engaging a panel locking mechanism. The ferromagnetic flap may be lifted by using a magnet. The magnet may be may be embedded in a suction cup device which is designed to lift and maneuver an object with a relatively flat surface, e.g. a glass pane. The suction cup device may, when suction is applied, be attached to glass covering the PV panels, and thus the suction cup device may be used to move the PV panels.
