Adjustable Door Lock Mounting Bracket for Trim Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door lock mounting systems face compatibility issues due to differences in mounting patterns between trims and exit devices, limiting their interchangeability and universal application.
Innovation Solution
A mounting system featuring a chassis with a sliding attachment bracket that can translate within a mounting plane, allowing the attachment posts to adjust between different positions to accommodate various mounting patterns, ensuring compatibility with multiple exit devices and trims.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting pattern is used for door locks, then the mounting structure is simple and stable, but compatibility with different exit devices and trims is limited
Solution Approach 1:
The attachment bracket is designed to slide within a pocket along a guide surface, transitioning from a fixed position to a dynamically adjustable position. This allows the mounting system to adapt to different mounting patterns while maintaining structural stability through controlled movement constraints.
Solution Approach 2:
The mounting system is divided into separable components: a chassis with pocket, an attachment bracket with guide surface, and fasteners. This segmentation allows the bracket to be independently adjusted and repositioned to accommodate different exit devices and trims without replacing the entire mounting system.
2Adaptability or versatility
If different mounting patterns are used for various exit devices, then compatibility is improved, but the mounting process becomes more complex and time-consuming
Solution Approach 1:
The attachment bracket is pre-configured with a guide surface and pocket interface that enables quick sliding adjustment. This preliminary design allows installers to rapidly reposition the bracket between different mounting patterns without complex assembly or disassembly procedures, significantly reducing installation time.
Solution Approach 2:
The attachment bracket serves multiple functions: it provides a stable mounting interface, enables adjustment between different mounting patterns, and works with various fastener types. This multi-functionality allows a single bracket design to accommodate multiple exit devices and trim combinations, reducing the need for multiple specialized mounting components.
3Adaptability or versatility
If the attachment bracket is made adjustable to accommodate different positions, then compatibility with various mounting patterns is improved, but the stability and precision of mounting may be compromised
Solution Approach 1:
The attachment bracket implements controlled dynamics through a guide surface that constrains movement to a specific linear path within the pocket. This ensures adjustability along the desired axis while preventing unwanted movements that would compromise mounting stability and precision.
Solution Approach 2:
The guide surface acts as an intermediary element between the attachment bracket and the pocket. It mediates the adjustment process by providing a controlled sliding path that maintains proper alignment and positioning, ensuring that the bracket remains stable once positioned at any point along the adjustment range.

AI summary
A mounting system for a door lock is provided. The mounting system may include a chassis having a pocket and an attachment bracket. The attachment bracket may include at least one attachment post extending parallel to an attachment post axis and a retaining plate affixed to the at least one attachment post. The attachment bracket may move relative to the chassis between at least a first position and a second position to provide different mounting patterns for a variety of associated door lock components such as exit devices or trims.
