Door Lock Installation Kit Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Installing door lock hardware on doors can be challenging due to the difficulty in accurately locating and aligning holes, especially with varying door widths and backset distances, which requires precise measurements and positioning.
Innovation Solution
A door lock installation kit that includes a side hole guide, a guide housing, a back housing, and a front hole guide, allowing for easy alignment and clamping of the door to position the guides correctly for drilling holes, accommodating different standard door widths and backset distances through movable components and a strike plate locator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional drilling methods are used to locate and position holes, then the installation can be completed, but the process requires difficult measurements and positioning with low accuracy
Solution Approach 1:
The patent introduces a guide tool as an intermediary device between the installer and the door. This guide tool includes positioning elements that physically locate the exact positions of the front face hole and side face hole, eliminating the need for complex measurements. The guide tool acts as a mediator that translates the installation requirements into precise physical positions, thereby improving measurement precision while maintaining ease of operation.
Solution Approach 2:
The guide tool performs preliminary positioning actions before the actual drilling process. By pre-establishing the correct positions and orientations of the holes through mechanical guides and positioning elements, the system eliminates the need for difficult measurements during the installation process. The preliminary positioning ensures high accuracy while simplifying the overall installation procedure.
2Adaptability or versatility
If a fixed guide tool is used, then the positioning can be simple, but it cannot accommodate varying door widths and backset distances
Solution Approach 1:
The guide tool incorporates adjustable and movable components that allow it to adapt to different door widths and backset distances. The positioning elements can be moved along guide rails or adjusted to different positions, enabling the same guide tool to accommodate various door specifications. This dynamic capability provides versatility without requiring multiple different guide tools for different door types.
Solution Approach 2:
The guide tool is designed as a universal device that can handle multiple door configurations. By incorporating adjustable positioning mechanisms and interchangeable components, the single guide tool can accommodate different door widths, thicknesses, and backset distances. This multi-functionality achieves adaptability while keeping the device structure relatively simple compared to having multiple specialized tools.
3Measurement precision
If precise measurements are taken for each installation, then hole positioning accuracy can be achieved, but the installation time increases
Solution Approach 1:
The guide tool performs all necessary positioning measurements and calculations in advance through its pre-configured mechanical structure. The correct hole positions are predetermined by the guide tool's design, eliminating the need for time-consuming measurements during installation. Installers simply attach the guide tool and drill through the pre-positioned openings, achieving high precision while maintaining fast installation speed.
Solution Approach 2:
The guide tool is self-positioning and self-aligning through its mechanical design. It automatically locates the correct positions on the door without requiring the installer to perform measurements or calculations. The guide tool serves itself by incorporating reference surfaces and positioning elements that naturally align with standard door features, thereby achieving accurate hole positioning rapidly without sacrificing productivity.
