Ceiling Anchoring Device Locking Rail System Concrete Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ceiling anchoring devices face issues with residual concrete obstructing the threading of the shaft and unwanted rotation of the anchor within the concrete, leading to labor-intensive installation and reduced stability.
Innovation Solution
A ceiling anchoring device with a locking rail system comprising a rod insertion rail, a pin insertion rail, and a locking rail, along with a plug and cap to secure the anchoring rod, preventing concrete entry and ensuring stability by eliminating threading and allowing easy concrete removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded shaft is used for anchoring, then the anchor can be securely fastened to the substrate, but residual concrete gets stuck in the threading making removal labor intensive
Solution Approach 1:
The shaft is divided into two distinct sections: a threaded section for secure anchoring and a smooth section for easy concrete removal. This segmentation allows each portion to serve its specific function optimally - the threaded portion provides reliable fastening while the smooth portion enables effortless concrete extraction without requiring manipulation to knock away concrete
2Ease of operation
If a circular head is used for the anchor, then the anchor can be easily inserted into the substrate, but the anchor rotates within the concrete reducing stability
Solution Approach 1:
The head is designed with an asymmetric hexagonal shape instead of a circular form. This asymmetric geometry prevents rotation within the concrete substrate while maintaining ease of insertion, as the hexagonal configuration allows straightforward driving into the substrate but resists rotational movement once installed
3Adaptability or versatility
If a threaded shaft with multiple diameters is used to accommodate different rod diameters, then the device becomes more versatile, but the threading complexity increases concrete obstruction problems
Solution Approach 1:
The shaft incorporates multiple smooth bore sections with different diameters instead of threaded sections, allowing accommodation of various rod diameters. This segmentation into differently sized smooth passages provides versatility for different rod sizes while eliminating the threading that causes concrete to become stuck
Solution Approach 2:
The smooth-bore design accepts that concrete will enter the shaft during installation, but designs the shaft so that concrete can be easily removed without damage or special tools. The shaft effectively 'disposes' of the concrete obstruction problem through its geometry, requiring no additional mechanisms to prevent or remove concrete

AI summary
A ceiling anchoring device with a locking rail system is disclosed. The device comprises an anchor having a shaft, a head attached with an end of the shaft, and a rail system. The rail system comprises rod and pin insertion rails, a turning space, and a locking rail. A rod having a perpendicular pin is inserted into the rod and pin insertion rails and pushed along the shaft until the rod and pin enter the turning space in the shaft. The rod and pin can then be turned one-quarter turn and be lowered into the locking rail, whereby the rod and pin are retained in the shaft of the anchor. A plug and cap are inserted into the turning space to secure the rod and pin within the locking rail.
