Hollow Tip Drill Bit for Cable Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing cables in existing buildings are inefficient, requiring multiple steps due to interference from building materials and structures, and involve complex procedures for guiding cables through apertures made by drill bits.
Innovation Solution
A drill bit with a hollow tip and attachment mechanism allows the cable to be attached and passed through the aperture without removing the drill bit, simplifying the installation process by enabling manual movement of the drill bit with the attached cable through the material, reducing the number of steps required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drill bit is removed from the aperture after making the hole, then the cable can be inserted, but the installation process requires multiple steps and more time
Solution Approach 1:
The patent combines the drill bit and cable guide functions into a single integrated tool. The cable is attached to the drill bit itself, allowing the drill bit to serve dual purposes: creating the aperture and then guiding the cable through it without removal. This merging of functions eliminates the need for separate cable insertion steps.
Solution Approach 2:
The cable is attached to the drill bit before the drilling operation is completed. This preliminary attachment allows the cable to be in position ready for insertion as soon as the aperture is created, eliminating the need for separate cable attachment and insertion steps that would follow drill bit removal.
2Ease of operation
If the cable is attached to the drill bit while the drill bit is in the aperture, then the cable can be pulled through easily, but the drill bit design becomes more complex
Solution Approach 1:
The cable is nested within or attached to the hollow shaft of the drill bit. The drill bit's hollow construction allows the cable to be fed through its length, with the cable essentially nested inside the drill bit structure during the pulling operation. This nesting arrangement simplifies the attachment mechanism while enabling easy cable retrieval.
3Ease of operation
If a guide wire or conduit is used to help insert the cable, then the cable can pass through the aperture, but additional materials and steps are required
Solution Approach 1:
The drill bit is designed to perform multiple functions: it creates the aperture through drilling, serves as a temporary holder for the cable during insertion, and acts as a pulling tool to retrieve the cable through the wall. This multi-functionality eliminates the need for separate guide wires, conduits, or other auxiliary insertion tools.

AI summary
A method of installing cable through material, for example, concrete, wood, masonry, plastic steel, or the like comprising a drill bit with a distal end having a hollow tip with an attachment mechanism for receiving the cable. The drill bit is drilled through the material, and left in place while the cable is attached to the proximal end of the drill bit. There is no need to remove the drill bit from the aperture or material to attach the cable thereto. After attachment to the drill bit, the cable is inserted through the aperture with the drill bit and removed from the drill bit after it passes through the material so it can be attached to a receiver device.
