Fence Kit Groove and Pin Alignment System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fence assembly kits lack the ability to easily mount fences without numerous parts and joints, fail to provide adaptable and aesthetically pleasing solutions, and often have visible screws, which can be unsightly, especially in jointed fences.
Innovation Solution
A fence kit featuring posts with specifically designed grooves and positioning pins that ensure panels are aligned and secured without visible screws, using U-shaped and H-shaped pieces for panel support and alignment, and an anti-theft device for added security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional fence assembly methods are used with multiple parts and joints, then the fence can be assembled, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The fence system is divided into modular components: panels with integrated positioning pins and posts with corresponding grooves. This segmentation allows each component to be independently manufactured and easily assembled, reducing the overall complexity of the assembly process while maintaining structural integrity.
Solution Approach 2:
The positioning pins are integrated directly into the panels, and the grooves are formed as part of the post structure. This merging of functions into single components eliminates the need for separate fastening parts and joints, significantly simplifying the assembly process and reducing the number of components required.
2Strength
If visible screws are used to secure panels, then the panels can be firmly attached, but the aesthetic appearance deteriorates
Solution Approach 1:
The visible screw fastening method is extracted and replaced with an invisible positioning system. The positioning pins fit into grooves to provide alignment and retention, while separate screws are used internally to secure panels without visible external fasteners, maintaining both strength and aesthetic appearance.
Solution Approach 2:
The positioning pins and grooves act as intermediaries between the panels and posts. They provide the necessary alignment and positioning functions that would otherwise require visible external fasteners, enabling a clean aesthetic appearance while maintaining secure attachment through internal fastening mechanisms.
3Reliability
If panels are securely fixed to prevent theft, then security is improved, but the assembly process becomes more complex
Solution Approach 1:
The positioning pins are pre-installed on the panels during manufacturing, and the grooves are pre-formed on the posts. This preliminary action ensures that when assembly occurs, the security features are already in place, preventing theft without requiring complex assembly steps. The anti-theft functionality is built into the basic assembly process.

AI summary
This kit comprises at least two identical posts (2a, 2b), each having four longitudinal grooves (16; 19) suitable for receiving and holding panels, the first two being arranged to receive and hold panels located at 180°, the third being arranged to receive and hold panels located at 90° to each of the preceding panels, and the fourth, to receive and hold panels located at 45°, 135° and 225° respectively to the panels inserted into the preceding grooves; each groove having a bottom, two opposing side walls (13; 20, 21) connecting to the bottom, and a front wall (14; 20c-22d) having a longitudinal slot (15; 23) for the passage of the associated panels, a receiving groove (17; 24) for the edge of the panels being formed in the bottom of each groove;and a set of panels, each of which has, along each of its vertical edges in the mounting position, at least one positioning pin (10A) for said panel.
