Hollow Tip Drill Bit for Cable Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for installing cables in existing buildings require multiple steps, including creating an aperture, removing the drill bit, and guiding the cable through, which is inefficient and can be hindered by obstructions.
Innovation Solution
A drill bit with a hollow tip and attachment mechanism allows cables to be attached while the drill bit is still in place, enabling the cable to be pulled through the aperture without removing the drill bit, reducing steps and overcoming obstructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drill bit is removed from the aperture after drilling, then the cable can be guided through the aperture, 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, merging the drilling operation and cable insertion into one continuous action, eliminating the need to remove the drill bit and separately guide the cable through the aperture.
Solution Approach 2:
The cable is attached to the drill bit before the drilling operation begins. This preliminary attachment ensures the cable is ready for immediate insertion through the aperture as soon as the hole is created, eliminating delays between drilling and cable installation.
2Productivity
If the drill bit is kept in place during cable attachment, then the cable can be pulled through the aperture in one step, but the drill bit structure must accommodate cable attachment mechanisms
Solution Approach 1:
The cable is nested within or attached to the drill bit structure, with the cable running through or alongside the drill bit shaft. This nesting allows the cable to be pulled through the aperture using the drill bit as a guide while minimizing additional structural complexity.
Solution Approach 2:
The drill bit serves as an intermediary tool that facilitates cable insertion. By attaching the cable to the drill bit, the drill bit mediates between the cable and the aperture, enabling one-step cable installation while the drill bit's existing structural elements are utilized for cable attachment.

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.
