Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable railing systems face challenges with exposed fasteners, complexity in design, inability to use with solid wood or concrete support members, and difficulties in handling heavy gauge cables, particularly in vertical configurations where tensioning is problematic.
Innovation Solution
The development of straight and corner cable termination assemblies with elongated cylindrical tensioning tubes and receptacle assemblies that can be integrated into wood or concrete support members, allowing for tensioning and concealment of cables, and using tools for installation and tensioning, enabling the use of heavy gauge cables and providing a secure, aesthetically pleasing solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fasteners (turnbuckles) are used to tighten cable rails, then the cables can be tensioned effectively, but the fasteners become exposed and unsightly and can be tampered with
Solution Approach 1:
The patent extracts the fastener components from the exterior of the railing system and relocates them inside the hollow stanchions. The cables terminate within the stanchion cavity, and tensioning is achieved through internal mechanisms rather than external turnbuckles, eliminating the aesthetic and security problems of exposed fasteners while maintaining effective cable tensioning
Solution Approach 2:
The cable termination and tensioning mechanisms are nested within the hollow stanchions. The cables, terminators, and tensioning devices are contained inside the stanchion cavity, creating a nested structure where the fastening system is housed within the support member itself, achieving both aesthetic concealment and functional integrity
2Reliability
If a cable railing system uses hollow metal vertical stanchions with complex fastening systems, then the cables can be secured, but the system becomes complicated and cannot be used with solid wood or concrete support members
Solution Approach 1:
The patent designs a universal cable termination assembly that can be adapted to multiple support member types including hollow metal stanchions, solid wood posts, and concrete columns. The system uses adjustable components and various mounting configurations to achieve reliable cable securing across different material types and structural forms, eliminating the need for type-specific fastening systems
Solution Approach 2:
The fastening system is divided into separate functional modules: cable terminators, tensioning devices, and mounting components. This segmentation allows each component to be optimized independently and facilitates adaptation to different support member types by reconfiguring how these modular elements are assembled and mounted
3Object-affected harmful factors
If heavy gauge cables are used in vertical configurations to eliminate the ladder effect, then security is improved, but tensioning the cables becomes problematic
Solution Approach 1:
The patent introduces intermediary tensioning devices such as turnbuckles, threaded rods, or spring-loaded mechanisms that mediate between the heavy gauge vertical cables and the support structures. These intermediary components provide a mechanical advantage system that enables easy tensioning and adjustment of heavy cables without requiring direct manual tensioning, thus maintaining security while improving ease of operation
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 solution allows for easy installation and tensioning of heavy gauge cables in both horizontal and vertical configurations, using wood, metal, or concrete support members, while concealing fasteners and enhancing security by eliminating the ladder effect, thus providing a robust and visually appealing cable railing system.
Implementation Method 1
an elongated cylindrical threaded tensioning insert extending in the threaded channel of the body of the receptacle, the threaded tensioning insert having an elongated tensioning insert channel of sufficient size and shape to enable passage of the cable through the channel and being able to rotate, or free spin, in either clockwise or counterclockwise direction against the cable terminating part to effectuate tensioning of the cable
