Nested Core Removal Assembly for Controlled Structural Coring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coring techniques pose a safety risk as they often result in cores falling into vulnerable areas, such as roadways or pedestrian paths, due to the inability to retain the core during removal.
Innovation Solution
A drilling assembly system that includes a first elongated member attached to the structure, a second elongated member with a cavity to receive the first member, and a collar mechanism that compresses the first member to prevent it from falling, allowing for controlled removal and retention of the core.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
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 core may fall into vulnerable areas such as roadways carrying traffic
Solution Approach 1:
The patent implements a nested structure where the core is received within a first elongated member (core retention device), which is in turn received within a second elongated member (drilling assembly). This nested arrangement ensures the core is contained and transported safely through the structure without falling into vulnerable areas below.
Solution Approach 2:
The first elongated member acts as an intermediary device between the core and the external environment. It provides a protective interface that prevents direct contact between the falling core and vulnerable areas, while still allowing the core to be extracted and removed safely.
2Adaptability or versatility
If a core is removed from a structure located above vulnerable areas, then the core can be tested or accessed, but the removal process creates danger to areas below
Solution Approach 1:
The patent employs preliminary action by first receiving the core into the first elongated member before completing the removal process. This preliminary containment ensures that even if the core becomes dislodged during extraction, it remains confined within the retention device and cannot fall into vulnerable areas.
Solution Approach 2:
The nested elongated members provide a protective cushioning system that prevents the core from falling. The structure is designed in advance to accommodate and protect the core throughout the entire removal process, eliminating the hazard of falling objects before it can occur.
3Productivity
If conventional coring techniques are used, then core extraction is achieved, but the core cannot be retained or controlled during removal
Solution Approach 1:
The first elongated member serves multiple functions: it acts as a retention device to hold the core, a transport mechanism to move the core through the structure, and a control element to manage the removal process. This multi-functionality integrates extraction and retention control into a single operational system.
Solution Approach 2:
The patent merges the core extraction function with the core retention function by integrating the first elongated member into the drilling assembly. The second elongated member receives both the drilling tool and the first elongated member, combining multiple operations into a unified system that maintains control throughout the process.

AI summary
A method for removing a portion of a structure is disclosed. The method includes attaching a first elongated member to the portion of the structure, receiving a second elongated member of a drilling assembly with the first elongated member, drilling into the structure with the drilling assembly while receiving the second elongated member with the first elongated member, and removing the portion of the structure that is attached to the first elongated member while urging the first elongated member with the second elongated member.
