Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fencing systems face challenges in seamlessly splicing horizontal rails while maintaining clear channels for cables or electrical wires, which are often obstructed by traditional fastening methods.
Innovation Solution
A splicing rail system with flexible tabs that secure adjacent horizontal rails without interfering with the channels, allowing cables or wires to pass through, and a bracket system for easy installation of heavy cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fastening methods are used to splice horizontal rails, then the rails can be securely connected, but the channels for cables or electrical wires become obstructed
Solution Approach 1:
The splicing mechanism is divided into separate functional components: the splicing rail with channel, the horizontal rails with end portions, and the tabs as independent fastening elements. This segmentation allows the channel to remain clear while the tabs provide secure fastening outside the channel path.
Solution Approach 2:
The fastening function is extracted from the channel interior and placed outside the channel. The tabs extend from the splicing rail and engage with the end portions of horizontal rails through slots or holes, removing the obstruction problem while maintaining secure connection.
2Object-affected harmful factors
If an external splicing system is used to avoid obstructing channels, then cable passage is maintained, but the complexity of the splicing mechanism increases
Solution Approach 1:
The splicing rail has different functional zones: the channel portion remains simple and clear for cable passage, while the tab portions provide the necessary fastening complexity only where needed. This local differentiation maintains simplicity in critical areas.
Solution Approach 2:
The tabs are simple, easily manufactured components that can be integrated into the splicing rail as a single piece or separate elements. Their simplicity reduces manufacturing complexity despite the external splicing configuration.
3Reliability
If tabs are flexed inward to secure horizontal rails, then the rails are prevented from moving or pulling out, but the installation process becomes more difficult
Solution Approach 1:
The tabs are designed as flexible elements that can dynamically change position during installation. They are initially in a neutral position for easy installation, then flexed inward to engage the horizontal rails, and finally held in the engaged position to provide secure fastening.
Solution Approach 2:
The tabs utilize elastic deformation as a parameter change to achieve their function. By flexing the tabs inward, their physical state changes temporarily during installation, allowing them to engage the rails, then they return to or remain in a secured state providing stable fastening.
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 system provides a seamless and secure connection between horizontal rails, enabling easy installation of cables or wires without obstructing the channels, enhancing structural integrity and safety.
Implementation Method 1
The splicing rail further includes flexible tabs formed or cut at the side of the splicing rail. With the horizontal rails received along the channel of the splicing rail, the tabs are flexed inward toward the channel and at least partially within slots of the horizontal rails to preclude or prevent the horizontal rails from moving or pulling out of the channels of the splicing rails.

AI summary
A fencing system includes a rail member having a slot. The rail member is configured to extend between adjacent posts of the fencing system. A splicing rail includes a channel and a flexible tab. With an end portion of the rail member received along the channel of the splicing rail, the flexible tab of the splicing rail flexes at least partially into the channel of the splicing rail and at least partially within the slot of the rail member to preclude the rail member from pulling out of the channel of the splicing rail.
