Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing core drilling methods are prone to inaccuracies and safety issues due to operator skill dependence, poor work practices, and the use of cumbersome or costly machinery, leading to inefficient and potentially dangerous drilling processes.
Innovation Solution
A core drill guide apparatus with an elongate body and fastening system, including an anchor bolt and anchor stud, that allows for secure attachment to a substrate, enabling precise guidance and easy removal of cores, reducing the need for complex machinery and minimizing operator risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing makeshift methods (tube, board held by feet) are used to guide core drilling, then some guidance is provided, but the operator's view of the proper location is blocked and safety is compromised
Solution Approach 1:
The guidance system is divided into separate components: a guide board with notches for positioning, a separate clamp mechanism for securing the guide board, and a core drill. This segmentation allows the guide board to provide accurate positioning without requiring the operator to hold it, eliminating the safety hazard of blocked views while maintaining precise core location control.
Solution Approach 2:
The guide board acts as an intermediary between the operator and the substrate. It provides a stable, pre-positioned reference structure that accurately locates the core drilling position without requiring the operator's body (feet, hands) to be in dangerous positions. The clamp mechanism serves as another intermediary to securely attach the guide board without temporary fixings into the floor.
2Measurement precision
If complicated machinery with temporary fixings is used for core drilling, then drilling guidance is improved, but the equipment becomes costly to purchase, operate, and store
Solution Approach 1:
The system is segmented into simple, separate components: a guide board, a clamp mechanism with anchor bolts, and a core drill. This avoids the need for complicated integrated machinery while maintaining accurate drilling guidance. Each component is simple enough to be easily manufactured and stored when not in use.
Solution Approach 2:
The guide board is designed to be self-positioning using notches that align with reference points on the substrate or surrounding structure. The clamp mechanism uses standard anchor bolts that can be installed without specialized equipment. This self-service capability eliminates the need for complicated adjustment mechanisms and reduces overall system complexity.
3Productivity
If levering is used to remove the core after drilling, then core extraction is attempted, but the process becomes awkward, dangerous, and time-consuming
Solution Approach 1:
The clamp mechanism serves as an intermediary that remains attached to the guide board after drilling. Instead of requiring awkward levering actions to remove the core, the clamp provides a secure attachment point that allows for safe and easy core extraction using appropriate tools, eliminating the dangerous levering process.
4Device complexity
If operator skill and accuracy are relied upon for core drilling, then no special equipment is needed, but the work quality becomes poor and unsafe practices occur
Solution Approach 1:
The guidance function is separated from the drilling function. The guide board with its notches and positioning features provides precise core location control independently of operator skill. The clamp mechanism secures the guide board in place, eliminating the need for operators to hold it with their feet or hands. This segmentation ensures consistent, high-quality core positioning while maintaining simple, safe operation.

AI summary
Disclosed is a core drill guide apparatus for providing a guide for a core drill apparatus to drill into a substrate to form a removable core. The apparatus includes an elongate body with an outer surface and inner space, having an entrance end, an exit end and side walls, a distance between the ends defining a length or height of the elongate body and a width. An passageway extends through the elongate body from entrance to exit end, adapted so that in use, it provides sliding receipt of a fastening system to clamp the apparatus to an outer surface surrounding a first hole in a substrate, allowing the apparatus to abut the outer surface and drill out a core in the substrate underneath and surrounding the first hole. A corresponding guide method and fastening system are also disclosed.
