Core Removal Assembly With Nested Retention Against Falling Cores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coring techniques pose a danger when removing cores from structures located above vulnerable or high traffic areas, as the extracted core may fall into roadways or other sensitive areas.
Innovation Solution
A method and system that involves attaching a first elongated member to the structure, receiving a second elongated member of a drilling assembly with the first elongated member, drilling into the structure while receiving the second elongated member, and removing the portion of the structure attached to the first elongated member while urging it with the second elongated member, thereby preventing the core from falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional coring techniques are used to remove a core from a structure, then the core can be extracted for testing or utility purposes, but the extracted core may fall into vulnerable areas such as roadways carrying traffic
Solution Approach 1:
The core is retained within a series of nested elongated members (first elongated member, second elongated member, third elongated member) that form a containment system. Each member is received within the previous one, creating a nested structure that securely holds the core during extraction and prevents it from falling into vulnerable areas below.
Solution Approach 2:
The elongated members act as intermediary containment structures between the core and the vulnerable area below. These intermediaries provide a safe pathway for core extraction while preventing direct contact between the falling core and vulnerable areas such as roadways.
2Productivity
If conventional coring techniques are used, then core removal is simple and quick, but safety is compromised in locations above vulnerable or high traffic areas
Solution Approach 1:
The nested elongated members provide a reliable safety mechanism that does not significantly complicate or slow down the core removal process. The containment system is integrated into the extraction procedure, maintaining productivity while ensuring the core cannot fall into vulnerable areas.
Solution Approach 2:
The containment system is divided into multiple segmented elongated members that can be independently positioned and secured. This segmentation allows for efficient assembly and deployment during the core extraction process, maintaining productivity while providing reliable safety through multiple containment stages.
