Door Hardware Locating Tool with Rotatable Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of door hardware, such as door locks, latches, and deadbolts, is often time-consuming and requires accurate positioning of edge and cross bores, which can be inefficient and inconsistent, especially in large-scale projects like building construction or refurbishment.
Innovation Solution
A door hardware locating tool with an edge wall and rotatable insert that adjusts between two positions to set the backset distance, allowing for precise positioning of edge and cross bores on a door, facilitating consistent and efficient installation.

Engineering Contradiction Analysis
1Productivity
If traditional manual methods are used to mark and position holes for door hardware installation, then flexibility and adaptability are maintained, but installation time increases and consistency/precision decreases
Solution Approach 1:
The locating tool is pre-configured with standardized backset distances and hole positions built into its structure. The template includes pre-marked positions for edge bores and cross bores at standard distances (e.g., 2-3/8 inches or 2-3/4 inches from the edge), allowing installers to directly transfer these pre-determined positions to the door without manual measurement and calculation during installation.
Solution Approach 2:
The locating tool incorporates adjustable components that allow the template to be adapted to different door thicknesses and hardware configurations. The tool can be positioned and secured at various locations along the door edge, and the template markings can be adjusted or repositioned to accommodate different backset requirements, providing both consistency and adaptability.
2Ease of operation
If multiple separate tools are used for marking edge bores and cross bores, then versatility is achieved, but device complexity and installation time increase
Solution Approach 1:
The locating tool combines multiple functions into a single integrated template: edge bore positioning, cross bore positioning, and backset distance measurement are all incorporated into one device. The template includes multiple reference marks and positioning features that simultaneously guide the location of both the edge bore (in the door edge) and the cross bore (through the door face), eliminating the need for separate marking tools and measurement devices.
Solution Approach 2:
The locating tool is designed as a universal template that can accommodate various door hardware types and standard backset distances. The same basic tool structure can be used for different door thicknesses and hardware configurations by adjusting the positioning or using different template configurations, making it a multi-functional device that replaces multiple specialized tools.

AI summary
A door hardware locating tool includes an edge wall having a first side, a second side opposite the first side, and an edge bore aperture that extends through the first and second sides. The edge bore defines a first axis that extends centrally through the edge wall and through the first and second sides. The door hardware locating tool also includes a side wall adjacent the edge wall. The side wall includes a first side, a second side opposite the first side, and a cavity defined between the first and second sides. The door hardware locating tool further includes an insert at least partially positioned within the cavity of the side wall. The insert is rotatable about a second axis that is perpendicular to the first axis between a first position and a second position. The insert includes a cross bore aperture.
