Threaded Railing Anchor Assembly for Leak-Free Roof Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for anchoring railings and fences on roofs and other structures face challenges such as water infiltration, difficulty in mounting radius posts, and lack of robust and reusable anchoring systems, especially when dealing with heavy loads and varying geometries like round or triangular posts.
Innovation Solution
A novel anchor and railing assembly featuring an anchor baseplate with a threaded bore and a baluster secured via a threaded mechanical fastener, allowing for easy installation and replacement, and providing a waterproof connection using a cylindrical post and U-shaped channel for glass railings, and adaptable for various geometries and applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional anchoring methods with bolts through the roof are used, then heavy structures can be mounted on roofs, but water infiltration occurs through the anchor conduits
Solution Approach 1:
The patent removes the traditional bolt-through-roof anchoring method entirely and replaces it with a surface-mounted baseplate system that attaches to the roof structure without penetrating the roofing membrane, thereby eliminating the water infiltration pathway while maintaining mounting strength
Solution Approach 2:
The patent introduces a baseplate as an intermediary component that distributes the mounting load across a wider area of the roof structure, eliminating the need for penetrating anchors while providing sufficient strength to support heavy structures
2Reliability
If adhesive and glue are used to seal anchor conduits, then water penetration is attempted to be prevented, but cracks develop over time due to roof movement causing leaks
Solution Approach 1:
The patent eliminates the vulnerable adhesive-sealed conduit system entirely by using a non-penetrating baseplate mounting approach, removing the source of crack development while maintaining long-term reliability
Solution Approach 2:
The baseplate design incorporates movement accommodation features that allow for thermal expansion and structural settling without compromising the seal or connection integrity, preventing cracks before they occur
3Ease of operation
If radius posts are mounted conventionally by passing through the structure, then posts can be attached to beams or rafters, but waterproofing becomes very difficult and vulnerable to leaks
Solution Approach 1:
The patent removes the penetrating post installation method entirely and replaces it with a surface-mounted baseplate system that accepts various post types without requiring penetration through the roof structure, thereby maintaining installation ease while achieving reliable waterproofing
Solution Approach 2:
The baseplate design provides universal mounting capability that accommodates multiple post geometries (round, square, rectangular) through a single standardized interface, eliminating the need for custom waterproofing solutions for each post type
4Strength
If conventional anchoring systems are used for heavy structures, then structures can be secured to roofs, but the systems create conduits for water penetration and are difficult to guarantee against water damage
Solution Approach 1:
The patent eliminates the water-penetration-prone conventional anchoring system and replaces it with a surface-mounted baseplate system that maintains anchoring strength while providing inherent waterproofing, enabling reliable guarantees against water damage

AI summary
An anchor and railing assembly for anchoring a baluster or balustrade to both outdoor and indoor structures, such as raised, generally flat or angled roof-like structures or indoor stairs or floors, which includes an anchor baseplate with a top surface and a bottom surface, and an internally threaded bore extending at least partially from the top surface generally towards the bottom surface, a baluster, fasteners for fastening the baluster to the anchor baseplate via its bore, and fasteners for fastening the anchor baseplate to either an outdoor or indoor structure.
