Detachable Threaded Anchor System for Secure Recovery and Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor systems face issues with unintentional separation and difficulty in detachment of the elongated tension element from the anchor body, leading to environmental contamination and handling challenges.
Innovation Solution
An anchor system with a detachable screw connection between the anchor body and the elongated tension element, utilizing a connection adapter with opposing threads and a hinge body with self-locking receptacles to prevent accidental separation, allowing for easy removal and reusability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tension element is permanently fixed to the anchor body, then the anchoring reliability is improved, but the ease of detachment and reusability deteriorates
Solution Approach 1:
The anchor system is divided into separable components: the anchor body with hinge body, the connecting element with T-shaped end, and the tension element with threaded end. These segments can be assembled and disassembled while maintaining secure connection during use. The hinge body with receptacle and crossbar provides a mechanical connection that is reliable during anchoring but allows for controlled detachment when needed.
2Ease of operation
If the connecting element uses a simple insertion method, then the ease of operation is improved, but the reliability against unintentional separation deteriorates
Solution Approach 1:
The connecting element features an asymmetric T-shaped end with a crossbar that fits into a corresponding receptacle in the hinge body. This asymmetric geometry provides inherent directional stability and prevents accidental disconnection, as the crossbar can only be removed by lifting upward rather than by lateral movement. The asymmetric design maintains simple operation while ensuring reliable connection.
3Strength
If the anchor body is driven deep into the ground, then the anchoring strength is improved, but the difficulty of removal and environmental impact worsens
Solution Approach 1:
The anchor system allows segmentation where the tension element and connecting element can be detached from the anchor body that remains in the ground. This enables the removable components to be recovered and reused while the anchor body stays embedded, reducing environmental impact and handling complexity for deep installations.
Solution Approach 2:
The design enables selective recovery of components: the tension element and connecting element can be detached and recovered for reuse, while the anchor body remains in the ground as a permanent fixture. This approach maximizes resource utilization and reduces environmental impact by recovering expensive components without requiring removal of the entire anchor system.
