Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed fixing device is used, then the structure is simple, but it cannot accommodate photovoltaic panels of different specifications
Solution Approach 1:
The fixing device employs a dynamic clamping mechanism where the clamping block can slide along the mounting rail and the spring provides adjustable clamping force. This allows the device to adapt to different panel sizes and weights by adjusting the clamping position and force, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The mounting rail with mounting slots and the slidable clamping block design enables a single fixing device to accommodate multiple photovoltaic panel specifications. The universal design allows the same device to be used across different applications by adjusting the clamping position, eliminating the need for multiple fixed devices for different panel sizes.
2Ease of operation
If a fixed fixing device is used, then the structure is stable, but mounting and removal is inconvenient
Solution Approach 1:
The dynamic clamping mechanism allows easy mounting and removal by simply sliding the clamping block along the rail and releasing the spring pressure. Meanwhile, when clamped, the spring maintains continuous pressure ensuring stable fixation. This resolves the contradiction between ease of operation and fixing reliability.
Solution Approach 2:
The spring acts as an intermediary element that provides both the ease of operation (by allowing simple engagement and disengagement) and the reliability (by maintaining constant clamping force). The mounting slot serves as an intermediary structure that guides the clamping block and ensures proper positioning during both mounting and fixation phases.
3Productivity
If a fixed fixing device is used, then manufacturing is simple, but working efficiency is reduced
Solution Approach 1:
The dynamic components (slidable clamping block, spring mechanism) enable quick adjustment and repositioning, significantly improving working efficiency by allowing rapid mounting and removal of panels. While this increases manufacturing complexity compared to a fixed device, the modular design keeps the manufacturing process manageable through standardized components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a firm and adjustable mounting system that improves working efficiency and increases the reuse frequency of photovoltaic panels by accommodating various specifications and allowing for easy installation and removal.
Implementation Method 1
The spring and the limiting plate are both sleeved on the bolt. The spring is arranged between the medium pressure block and the limiting plate, with its two ends abutting against the medium pressure block and the limiting plate respectively. The spring is configured to push the limiting plate to move toward the clamping block
Implementation Method 2
A lower surface of the side plate in contact with side edge of the photovoltaic pane is corrugated, allowing the side plate to tightly clamp the side edge of the photovoltaic panel
Implementation Method 3
The clamping block is provided with upward clamping teeth; an upper edge of the mounting slot is provided with downward clamping teeth; wherein the upward clamping teeth are configured to engage with the downward clamping teeth, in order to limit the sliding of the clamping block in the mounting slot, and combine the clamping block to the mounting rail firmly
Implementation Method 4
The side plate is provided with a through hole. The fixing device further includes a screw, where the screw is configured to penetrate through the through hole to firmly fix the medium pressure block and the photovoltaic panel together
