Door Latch Block with Rectangular Protrusion for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door latch assemblies often lack ease of mounting, precise alignment, and a clean, uniform appearance, especially in visible areas where doors need to provide a consistent surface when closed.
Innovation Solution
A door latch block apparatus with a first planar surface for mounting parallel to the door frame and a second planar surface for mounting flush, featuring a rectangular protrusion for secure attachment through the door frame and cylindrical openings for precise alignment of latch hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional door latch mounting methods are used, then installation is possible, but alignment precision and mounting ease are insufficient
Solution Approach 1:
The latch block is pre-configured with precisely positioned cylindrical openings and a rectangular protrusion during manufacturing. This preliminary preparation of alignment features eliminates the need for complex field alignment procedures, achieving high alignment precision while simplifying the actual mounting process.
Solution Approach 2:
The rectangular protrusion extending from the latch block serves as an intermediary alignment element that fits through the door frame aperture. This intermediary feature guides the latch block into precise position, ensuring accurate alignment without requiring complex mounting procedures.
2Shape
If visible area door requirements are considered, then aesthetic appearance is improved, but mounting flexibility is reduced
Solution Approach 1:
The latch block features a second planar surface specifically designed to mount flush with the door frame surface, creating a uniform appearance in visible areas. This localized design feature provides aesthetic quality where needed while the overall block structure maintains mounting flexibility through its standardized interface features.
3Reliability
If precise alignment of latching mechanism is achieved, then door securing reliability is improved, but mounting time and complexity increase
Solution Approach 1:
The cylindrical openings are pre-positioned with precise dimensions and locations during latch block manufacturing. This preliminary action ensures that when hardware is installed through these openings, the latching mechanism achieves precise alignment and reliable door securing without requiring time-consuming field adjustment procedures.
Solution Approach 2:
The rectangular protrusion acts as an intermediary alignment guide that facilitates quick and accurate positioning of the latch block relative to the door frame. This intermediary feature enables rapid mounting while ensuring the reliability needed for secure door latching.

AI summary
Various examples are directed to apparatus and methods for providing a door latch block assembly. An apparatus includes a first planar surface configured to mount parallel to and facing away from a first side of a door frame, and a second planar surface configured to mount flush with and facing toward the first side of the door frame. The apparatus further includes a rectangular protrusion extending from the second planar surface configured to extend through an aperture in the door frame and protrude from a second side of the door frame. The apparatus also includes cylindrical openings extending through the latch block apparatus configured to receive hardware for affixing a latching mechanism to a distal end of the protrusion. The apparatus is configured to provide precise alignment of the latching mechanism for securing the door frame to a door.
