Rotating Cavity Anchoring Stick for Fall Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fall protection equipment faces challenges in quickly and easily engaging with supporting anchors, especially those located in difficult-to-reach areas, such as ceilings, requiring cumbersome equipment like ladders.
Innovation Solution
An anchoring stick with a shaft, handle, and a cavity system that can change orientation from open to closed, featuring a locking mechanism and a hook for attaching safety harnesses to building anchors, allowing for quick and secure attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fall protection equipment is used to reach ceiling anchors, then workers can access anchors, but the equipment becomes cumbersome and requires ladders
Solution Approach 1:
The device is segmented into a shaft portion and a head portion that can rotate relative to each other. The head portion contains the cavity and opening mechanism, while the shaft provides reach. This segmentation allows the device to be manipulated in stages - inserting the shaft first, then rotating the head to close the opening, making the operation simpler despite the device's capability to reach difficult locations
Solution Approach 2:
The opening in the cavity is configured to rotate from an open position to a closed position, transforming the device from an open-state configuration to a locked-state configuration. This dynamic transformation allows the device to adapt its state during operation - open for insertion and closing for security - thereby simplifying the engagement process while maintaining secure attachment
2Productivity
If the cavity opening remains open for easy insertion, then anchoring is quick, but the attachment is not secure
Solution Approach 1:
The opening transitions dynamically from open to closed state. During insertion, the opening remains open to allow quick engagement of the anchor. Once the anchor is positioned, the opening rotates to close, securing the anchor inside the cavity. This dynamic state change resolves the contradiction by providing both quick insertion and secure retention
Solution Approach 2:
The device is designed with the opening预先 in an open state, allowing the anchor to be inserted first without obstruction. After insertion is complete, the opening then closes to secure the anchor. This preliminary open state enables quick attachment, while the subsequent closing action ensures security
3Reliability
If the anchoring stick has a fixed closed cavity, then security is maximized, but insertion becomes difficult
Solution Approach 1:
The cavity opening is designed to rotate between open and closed positions. During insertion, the opening is in the open position, allowing the anchor to be easily placed inside the cavity. After insertion, the opening rotates to the closed position, maximizing security by preventing the anchor from being removed. This dynamic configuration resolves the contradiction between ease of insertion and attachment security

AI summary
In some embodiments, an anchoring stick comprises a shaft, a handle located at one end of the shaft and a hook located at the other end. The hook defines a cavity. The anchoring stick has a first orientation and a second orientation. A perimeter of the cavity comprises an opening in the first orientation. The cavity is defined by a closed perimeter in the second orientation.
