Eccentric U-Shaped Connection Device for Angular Grid Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fence grid connection techniques fail to satisfactorily connect grids arranged angularly to a single post without compromising aesthetics or requiring additional posts, as they cannot be fixed at the same height, leading to costly and aesthetically detrimental solutions.
Innovation Solution
A U-shaped connection device with an eccentrically positioned screw opening allows for the fixation of grids at the same height on a post, enabling the connection of both aligned and angularly arranged grids to a single post, preserving the fence's aesthetic continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a single connection device is used to connect two grids arranged angularly to the same post, then the aesthetic continuity of the fence is preserved, but the connection devices cannot be fixed at the same height, requiring heavy modifications to the rails
Solution Approach 1:
The connection device incorporates an asymmetric fixing wing with an eccentric opening positioned at a distance from the centerline. This asymmetric design allows the device to be fixed at a specific height on the post while accommodating angularly arranged grids, eliminating the need for rail modifications and preserving aesthetic continuity.
2Reliability
If two juxtaposed posts are used to connect grids arranged at an angle, then the connection is structurally feasible, but the cost increases and assembly becomes more complex
Solution Approach 1:
The connection device is designed as a universal component that can connect grids in both aligned and angular arrangements to a single post. The tubular portion with U-shaped cross-section and eccentric fixing wing provides multi-functional capability, eliminating the need for additional posts and simplifying the overall fence structure.
3Ease of operation
If connection devices are fixed at different heights on the same post for angular grids, then the connection is possible, but the aesthetic appearance is compromised
Solution Approach 1:
The connection device features a localized asymmetric fixing wing with an eccentric opening that enables the device to be fixed at a specific height while accommodating angular grid arrangements. This local asymmetric design allows both angular grids to be connected at the same height on the post, maintaining visual continuity while enabling the connection.
