Positioning foot block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As solar panel weights and surface areas increase, existing positioning foot blocks struggle to provide sufficient stability and angular adjustment for secure mounting, leading to potential vibration issues.
Innovation Solution
A positioning foot block design featuring a support device with side lugs and a lateral screw mechanism that clamps the corner ends of an upright bar, allowing for angular adjustment and enhanced stability by securely fastening the upright bar to a corrugated sheet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the positioning foot block is designed to be more solid to support heavier solar panels, then the supporting strength is improved, but the device complexity increases
Solution Approach 1:
The positioning foot block is divided into multiple functional components: a support body for mounting, an extension member with clamping structure for angular adjustment, and a fastening mechanism. This segmentation allows each component to perform its specific function efficiently while keeping the overall design manageable and not overly complex.
Solution Approach 2:
The extension member is designed to be rotatable relative to the support body, enabling angular adjustment of the upright bar. This dynamic feature allows the structure to adapt to different mounting angles while maintaining firm clamping through the fastening mechanism, thus providing both flexibility and strength without excessive complexity.
2Device complexity
If the positioning foot block uses a simple clamping structure, then the device complexity is reduced, but the positioning stability deteriorates
Solution Approach 1:
The extension member is pre-configured with clamping surfaces and attachment points that engage with the upright bar corner ends. The fastening mechanism is pre-designed to apply clamping force in the correct direction, ensuring stable positioning from the moment of installation without requiring complex adjustment procedures.
Solution Approach 2:
The extension member acts as an intermediary between the support body and the upright bar, providing a specialized clamping interface that engages with the corner ends of the upright bar. This intermediary component translates the fastening force into effective clamping action, ensuring stable positioning with a relatively simple overall structure.
3Adaptability or versatility
If the positioning foot block allows angular adjustment, then the adaptability is improved, but the reliability deteriorates due to potential loosening
Solution Approach 1:
The extension member is designed to be rotatable relative to the support body, enabling angular adjustment of the upright bar. This dynamic feature allows the structure to adapt to different mounting angles while maintaining firm clamping through the fastening mechanism, thus providing both flexibility and reliability.
Solution Approach 2:
The fastening mechanism is designed to apply continuous clamping force that counteracts any loosening tendency. The clamping structure is pre-configured to maintain firm engagement with the upright bar corner ends even during angular adjustment, preventing loosening before it can occur.

AI summary
A positioning foot block for the mounting of an upright bar is disclosed to include a support device having a bottom wall, two side walls respectively extended from opposing left and right sides of the bottom wall and a positioning space surrounded by the bottom wall and the side walls for receiving the upright bar. Each side wall of the support device has two side lugs respectively extended from opposing front and rear sides thereof toward the positioning space and respectively clamped on respective corner ends of the upright bar. Thus, the structural design of the positioning foot block can clamp the corner ends of the upright bar firmly, prohibiting the upright bar from vibration and enhancing its positioning stability.
