Door Lock Mounting Assembly for Tool-Free Secure Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door lock mechanisms often require complex tool-based installation and lack seamless integration of manual and automated operation modes.
Innovation Solution
A door lock system featuring a mounting bracket that allows tool-free attachment to a door, combined with a manual thumb turn and a motorized drive train for automated operation, enabling easy installation and dual-mode functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional door lock mechanisms are used, then reliable locking function is achieved, but installation requires complex tools and procedures
Solution Approach 1:
The door lock system is divided into separate components: a body assembly, a mounting bracket, and a latch mechanism. The latch is movably mounted to the body, allowing it to be manipulated independently for tool-free attachment to the mounting bracket. This segmentation enables simplified installation procedures while maintaining the overall functional integrity of the locking system.
Solution Approach 2:
The latch mechanism is designed to be manually movable between open and closed positions by the user without requiring external tools. The latch can be moved to attach the body to the mounting bracket by hand, enabling self-service installation and removal of the door lock system.
2Ease of operation
If manual operation only is provided, then simple structure is maintained, but user convenience and automation capability are limited
Solution Approach 1:
The door lock system is designed to support multiple operation modes: manual operation via thumb turn and automated operation via motorized lock drive. The lock drive can be movably mounted to the body and coupled to the lock mechanism, allowing the same physical system to perform both manual and automated functions, thereby increasing user convenience without requiring separate systems.
Solution Approach 2:
The system transitions from a static manual-only operation to a dynamic system that can adapt between manual and automated modes. The lock drive mechanism can be engaged or disengaged as needed, allowing the system to change its operational characteristics based on user needs, thereby enhancing versatility while maintaining manageable complexity.
3Loss of time
If tool-free attachment is implemented, then installation time is reduced, but attachment security may be compromised
Solution Approach 1:
The latch acts as an intermediary mechanism between the body and the mounting bracket. It provides a controlled interface that enables tool-free attachment while maintaining secure connection. The latch can be moved to engage with the mounting bracket, creating a reliable mechanical connection without requiring tools, thus resolving the contradiction between installation speed and attachment security.

AI summary
A door lock that includes a latch adapted to be moved manually relative to a mounting bracket and lock body to attach the body to the mounting bracket. The latch may be movably mounted to the body, and arranged to capture a portion of the mounting bracket between the latch and the body. A detent may be used to hold the latch in the closed position relative to the body, and a spring may be adapted to bias the latch away from the body.
