Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching electrical wiring to support surfaces using staples are cumbersome and prone to damaging the wiring, especially when working in confined spaces or on ladders.
Innovation Solution
A drill bit with a central gear and planetary gears that drive two screw-driving tools to securely fasten staples with parallel screws, preventing deep penetration and potential wiring damage, while allowing for easier and faster attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hammer and staple are used to fasten wiring to support surfaces, then the wiring can be attached to the support, but the wiring may be damaged and the process is slow and difficult in confined spaces
Solution Approach 1:
The patent replaces the traditional hammer-staple mechanical system with a power drill-driven screw fastening system. The drill provides controlled rotational force to drive screws into the support surface, eliminating the need for manual hammering and reducing the risk of wiring damage while improving ease of operation in confined spaces
Solution Approach 2:
The invention changes the fastening mechanism from impact-driven staples to rotation-driven screws. This parameter change allows for controlled insertion depth and force application, preventing wiring damage while maintaining secure attachment to support surfaces
2Reliability
If a hammer and staple are used to fasten wiring to support surfaces, then the wiring can be attached to the support, but the process is time-consuming and labor-intensive
Solution Approach 1:
The patent replaces the manual hammer-staple system with a power drill-driven screw fastening system, significantly increasing fastening speed and productivity while maintaining secure attachment through the controlled driving of screws into the support surface
Solution Approach 2:
The drill-driven screw system provides self-aligning and self-controlling fastening action. The screw threads automatically engage with the support material, and the drill controls the insertion depth, reducing the need for manual adjustment and improving overall productivity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quicker, safer, and more efficient attachment of electrical wiring to support surfaces without damaging the wiring, improving worker safety and efficiency.
Implementation Method 1
The drill bit includes a first planetary gear and a second planetary gear, which are meshed with the central gear. The central gear rotates the planetary gears, which, in turn, rotate two screw-driving tools.

AI summary
A drill, drill bit and staples for use in attaching staples to a support by driving two parallel screws in the same direction simultaneously, one held by each side of the staple, so as to secure wiring to the support using the staple. The drill bit includes a central gear and two planetary gears, which gears rotate a screw-driving tool. The drill bit is held by the chuck of a drill and, when its central gear is rotated, rotates the planetary gears that drive the two screws. A harness may used to attach the housing of the drill bit to the drill to prevent rotation of the housing when the central and planetary gears are rotating. The drill may be rotatable from horizontal to vertical, telescoping and permit the bit to be rotated 90 degrees.
