Fence Post Buckle Structure for Fast Cross Bar Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fence structures require time-consuming assembly using screw pieces and are not adaptable for cross bars made of different materials like aluminum, wood, or glass.
Innovation Solution
A vertical post structure with axially extending combining slots, notches, clamping boards, and buckle parts that allow easy assembly and secure attachment of cross bars, along with a connecting base for different materials, and an upper stop plate to prevent separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw pieces are used to connect vertical posts and cross bars, then the connection is secure, but the assembly time is excessive
Solution Approach 1:
The patent replaces the traditional screw-fastening mechanical system with a buckle-based mechanical interlocking system. The buckle parts engage with the combining slots to provide secure connection without requiring threading or tightening operations, thereby eliminating the time-consuming aspect of screw assembly while maintaining connection security through the interlocking buckle-slot mechanism.
Solution Approach 2:
The invention extracts and removes the screw pieces from the connection system, replacing them with integrated buckle parts that are part of the vertical post structure. This extraction eliminates the need for separate fastening components and simplifies the assembly process to a direct snap-fit or interlocking action.
2Ease of manufacture
If the vertical post structure is designed for specific cross bar materials, then the connection is optimized, but the adaptability to different materials is reduced
Solution Approach 1:
The patent designs the combining slots and buckle parts with universal geometric features that can accommodate cross bars made of different materials (aluminum, wood, glass, etc.). The slots are dimensioned and shaped to provide consistent engagement regardless of the cross bar material, allowing the same vertical post structure to be used with various material types without requiring design modifications.
Solution Approach 2:
The invention maintains consistent geometric parameters of the combining slots and buckle parts across different applications. By keeping the slot dimensions, buckle shape, and engagement geometry unchanged, the structure achieves material-agnostic adaptability while maintaining optimized connection characteristics for each specific material type through proper sizing and tolerancing.
3Productivity
If a simple connection structure is used, then the assembly is quick, but the security of attachment is insufficient
Solution Approach 1:
The connection system is segmented into distinct functional components: the combining slots in the vertical post, the buckle parts that engage the slots, and the cross bars. This segmentation allows for a simple, quick assembly process where each component performs a specific function, while the cumulative effect of multiple engagement points (multiple slots and buckles) provides secure attachment.
Solution Approach 2:
The buckle parts are designed to nest within or engage the combining slots, creating a nested connection structure. The cross bars pass through or engage with the buckle parts, forming a nested sequence of interconnected components. This nesting provides structural security through multiple levels of engagement while maintaining assembly simplicity.

AI summary
A vertical post structure of a fence comprises an axial slot on at least one side of a post, and an axial notch at an end of the slot facing the post. An inner wall of the slot and the two sides near to the notch extend obliquely to form a clamping board, wherein a tail end of the clamping board has a buckle part. Each buckle part is positioned within the projection range of the notch, and a plate is fixed with a stop end of the post and corresponds to the slot. The buckle parts directly clip and buckle the end parts of the cross bars to fix them to the post, or the post can be assembled with the cross bars fixed inside the slot and to a base, and the plate prevents separation of the cross bars from the post.
