Drilling Tool Hollow Shaft Cabling Chaseway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools fail to efficiently run cabling through existing walls due to obstructions and difficulties in creating and maintaining holes, with prior solutions like wire snakes and conduits being cumbersome and prone to obstruction or damage.
Innovation Solution
A drilling tool with a hollow primary shaft attached to a drill bit that creates a hole and simultaneously forms a protected chaseway for cabling, allowing for easy insertion of cabling or conduits, adaptable to various wall thicknesses and types of cabling, and featuring removable components for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a drill is used to create a hole through existing walls, then access to the interior is achieved, but the hole is frequently obstructed by materials within the wall making it difficult to run new cabling
Solution Approach 1:
The hollow shaft is attached to the drill bit before drilling begins. As the drill bit creates the hole through the wall, the hollow shaft simultaneously forms a clean, unobstructed passage through the same path. This preliminary action ensures that the cabling pathway is prepared in advance, eliminating the problem of obstructions that would otherwise block the hole after drilling is complete.
2Ease of operation
If wire snake devices are used to pull cabling through walls, then cabling can be inserted, but the wire must be attached to the device which involves effort and time, and the attachment may break or the wire may be damaged during pulling
Solution Approach 1:
The invention extracts the problematic attachment step entirely from the process. Instead of requiring the wire to be attached to a separate snake device, the hollow shaft itself becomes the cabling pathway. The shaft is simply inserted into the drilled hole and the cabling is fed directly through it, eliminating attachment points that could fail and removing the wire from contact with potential damage sources during insertion.
3Reliability
If rigid or semi-rigid conduit is used to run cabling, then cabling can be protected, but inserting the conduit into walls is just as difficult as inserting cabling directly due to obstructions and alignment difficulties
Solution Approach 1:
The invention merges the hole-drilling function with the conduit-formation function into a single integrated tool. The hollow shaft is permanently attached to the drill bit, so that one operation simultaneously accomplishes both tasks: creating the hole and forming the protected cabling pathway. This eliminates the separate step of inserting a conduit after drilling, which is difficult due to alignment requirements and obstructions.
4Reliability
If conventional drilling and separate conduit insertion is performed, then cabling can be protected, but the process requires multiple steps and is time-consuming
Solution Approach 1:
The hollow shaft combines multiple functions into a single component: it serves as both the drill attachment and the final cabling conduit. This merger allows the installer to complete both hole creation and conduit installation in one continuous operation, dramatically reducing the time and steps required compared to conventional methods that require separate drilling and conduit insertion steps.

AI summary
An improved drilling tool for drilling into and through walls for the purpose of inserting cabling within same, comprising a drill bit and an elongated primary shaft suitably adapted to create a chaseway within a wall during the drilling process. The elongated primary shaft may itself be the chaseway, in which case it is hollow, or it may carry a chaseway in the form of a conduit placed over a solid primary shaft. The cabling is then placed into the wall by use of the chaseway or by use of a separate conduit inserted into the wall through the chaseway.
