Door Hardware Locating Tool for Precise Bore Alignment
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 labor-intensive, especially in large-scale projects where consistency in height and position across multiple doors is desired.
Innovation Solution
A door hardware locating tool with a clamping mechanism and a movable insert that adjusts between two backset positions, allowing for precise alignment and drilling of edge and cross bores, along with a hole saw and plug for controlled cutting, facilitates quick and accurate installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual marking and drilling methods are used for door hardware installation, then flexibility in operation is maintained, but installation time and labor intensity increase significantly
Solution Approach 1:
The locating tool is divided into multiple functional components: a body with clamping mechanism for positioning, an insert with aperture for drilling guidance, and a depth stop mechanism. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability
Solution Approach 2:
The locating tool integrates multiple functions into a single device: it clamps to the door edge, positions the cross bore location, controls drilling depth, and guides the drill bit. This multi-functionality eliminates the need for multiple separate tools, directly improving installation speed without proportionally increasing complexity
2Manufacturing precision
If precise manual measurement and marking are performed for each door, then positioning accuracy is achieved, but installation time increases due to repetitive manual operations
Solution Approach 1:
The locating tool is pre-configured with fixed dimensional relationships between its components. The insert's aperture is positioned at a predetermined distance from the clamping surface, and the depth stop is set to a specific height. This preliminary action ensures that when the tool is clamped to the door, accurate hole positions and depths are automatically achieved without time-consuming manual measurements
Solution Approach 2:
The tool performs self-positioning through its clamping mechanism. When clamped to the door edge, the tool automatically aligns itself, and the aperture and depth stop self-adjust to the correct positions based on the clamping force. This self-service capability eliminates the need for manual alignment and measurement operations
3Stability of the object's composition
If consistent hole positions are required across multiple doors, then uniformity in installation is achieved, but the complexity of maintaining consistency increases with manual methods
Solution Approach 1:
The single locating tool is designed to be universally applicable to multiple doors with consistent geometry. Its clamping mechanism and fixed dimensional relationships ensure that the same hole positions and depths are achieved on every door, providing installation consistency without requiring complex adjustment mechanisms for each door
Solution Approach 2:
The tool allows for parameter standardization through its fixed design. The distance between the clamping surface and the aperture, as well as the depth stop height, are set to standard values that ensure consistent installation across all doors. This parameter standardization maintains stability and uniformity in the installation composition

AI summary
A door hardware tool includes an edge wall with a first side, a second side opposite the first side, and an edge bore aperture that extends through the first side and the second side. The edge bore defines a first axis that extends centrally through the edge bore and through the first side and the second side. The door hardware tool also includes a side wall coupled to the edge wall. The sidewall includes a first side, a second side opposite the first side, a cavity defined between the first and second side, and a cross bore aperture moveable between a first setback position and a second setback position within the cavity along a second axis. The second axis is parallel and offset from the first axis.
