Lightning Protection Mounting Base External Roof Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for lightning arresters on building roofs face challenges such as requiring roof penetration or cutting, limited angular adjustment of tubular stands, and stability issues during storms due to restricted transverse expansion.
Innovation Solution
A holding device with a mounting base and tubular or rod-shaped tripod that allows stepless angular adjustment of the tripod's longitudinal axis and has a maximum transverse extent of at least 30 cm, enabling external fastening to the roof covering without penetrating it, with telescoping elements and adaptable fastening mechanisms for various roof types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mounting base is fastened under the roofing to the supporting structure, then the attachment is secure, but the roofing must be removed or cut open at the attachment point
Solution Approach 1:
The patent inverts the conventional mounting approach by fastening the mounting base from the outside of the roofing to the supporting structure, rather than from underneath. This allows the roofing to remain intact and properly sealed, eliminating the need to remove or cut open the roofing at attachment points while still achieving secure attachment through the roofing material.
2Ease of manufacture
If the tubular stand is fixed at predetermined angular positions, then the manufacturing is simplified, but the angular adjustment range is limited
Solution Approach 1:
The patent transitions from a static mounting system with fixed angular positions to a dynamic system that allows continuous angular adjustment. The holding means enables the tubular stand to be fixed at any angular position within a range, providing adaptability for different roof pitches while maintaining a relatively simple bracket and clamp mechanism.
3Area of stationary object
If the transverse extent of the mounting base is limited, then the device size is reduced, but stability during storms is compromised
Solution Approach 1:
The patent extends the mounting base in the transverse direction to achieve a maximum transverse extent of at least 30 cm, providing a wider base for better stability during storms. This dimensional extension allows the fastening means to be positioned farther apart, creating a more stable configuration that can withstand strong winds and storm conditions.
4Adaptability or versatility
If the tripod is mounted on the roof with limited transverse expansion, then the device fits smaller roofs, but stability problems occur during strong storms
Solution Approach 1:
The patent increases the transverse extent of the mounting base to at least 30 cm, creating a wider footprint that enhances stability during storms. This dimensional change allows the device to maintain stability across various roof sizes and wind conditions by positioning the fastening means farther apart in the transverse direction.
