Segmented Hole Anchor Head Assembly for Simplified Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hole anchors have complex manufacturing processes and assembly challenges due to the monolithic anchor head, requiring multiple through holes and intricate processing, making them time-consuming and difficult to assemble.
Innovation Solution
The anchor head is divided into two side rods with recesses and recessed openings, allowing for easier manufacturing and assembly, with a pivot unit and guiding cord enabling greater rotational degrees and secure engagement with a snap hook.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the anchor head is made as a monolithic column, then the structure is simple in design, but the manufacturing process becomes complex and assembly becomes difficult
Solution Approach 1:
The anchor head is divided into two separate side rods (first side rod and second side rod) that are juxtaposed to each other. Each side rod has its own through holes and recesses that can be manufactured independently, avoiding the complexity of processing multiple through holes in a monolithic structure. The side rods are then assembled together using a pivot unit, simplifying both manufacturing and assembly processes.
2Ease of manufacture
If the monolithic anchor head is processed with multiple through holes, then the anchor shaft and cord can be disposed, but the processing becomes more complicated and time-consuming
Solution Approach 1:
By segmenting the anchor head into two side rods, each with fewer through holes (one per side rod), the processing time for each component is reduced. The assembly of these pre-processed side rods is then completed by simply connecting them with the pivot unit, significantly reducing total assembly time compared to processing all holes in a monolithic structure.
Solution Approach 2:
The side rods are prepared in advance with their respective through holes and recesses before final assembly. This preliminary preparation allows for parallel processing of components, reducing the overall manufacturing cycle time.
3Device complexity
If the anchor head is a monolithic column, then the structure is unified, but matching holes during assembly is difficult and time-consuming
Solution Approach 1:
The anchor head is segmented into two side rods with corresponding recesses and through holes. The pivot unit serves as a connecting element that aligns and joins the side rods. This segmentation makes hole matching straightforward during assembly, as each side rod has predetermined connection points, eliminating the difficulty of matching multiple holes in a monolithic structure.

Function Achieved in This Case
Simplifies manufacturing and assembly by dividing the anchor head into two parts, facilitating easier alignment and secure fixing in a hole, reducing assembly time and complexity.
Implementation Method 1
A spring fits around a periphery of the anchor shaft, wherein a top end and a bottom end of the spring respectively abut against the plug and the annular structure
Implementation Method 2
making the anchor head assembly that is rubbing against the hole wall to rotate to restore to its original position and to be stuck at the hole for fixing

AI summary
A hole anchor has a plug. An anchor shaft and a cord respectively pass through a center and a periphery of the plug. A top end and a bottom end of the anchor shaft respectively have a head and an annular structure. A spring is disposed between the annular structure and the plug. Two side rods of an anchor head assembly are juxtaposed respectively on a left side and a right side of the head. Two sides of each of the side rods respectively have a closed end and an open end. The two closed ends are engaged with each other via a concave-convex structure. A top side of each of the two open ends is pivotally connected to a pin connected to the cord. A pivot unit pivotally penetrates a middle of the two side rods and the head.
