Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional locks are difficult to install and lack adaptability, compromising their effectiveness in diverse home settings, and often require alterations to doors or door frames, which can damage them.
Innovation Solution
A lock mechanism that is easily installed without damaging the door, featuring a catch mechanism and release mechanism connected by a U bracket, allowing for secure attachment and operation from both sides of the door, with components designed to fit various door installations and door frame gaps, including options for tool-free installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locks are installed on existing doors, then secure door locking is achieved, but installation difficulty and time consumption increase
Solution Approach 1:
The lock device is divided into separate components: a lock body that attaches to the door, a strike plate that engages with the door frame, and a locking mechanism. This segmentation allows each component to be independently positioned and installed, simplifying the overall installation process while maintaining security functionality.
Solution Approach 2:
The patent introduces intermediate mounting elements such as adhesive strips, mounting brackets, or template guides that facilitate the attachment of the lock to the door and the engagement with the door frame without requiring direct complex integration, thereby reducing installation time and complexity.
2Reliability
If traditional locks are installed on existing doors, then secure door locking is achieved, but door or door frame damage occurs
Solution Approach 1:
The lock mechanism is designed to self-adjust and self-align during installation through features such as adjustable mounting positions, flexible strike plate engagement, and adaptive locking components. This self-service capability allows the lock to accommodate existing door variations without requiring forceful installation that could cause damage.
Solution Approach 2:
The patent incorporates adjustable parameters such as mounting hole positions, strike plate depth, and locking mechanism tension that can be modified during installation to match the specific door and frame characteristics, thereby achieving secure locking without damaging the door or frame structures.
3Reliability
If traditional locks are installed on existing doors, then door security is achieved, but adaptability to diverse door configurations decreases
Solution Approach 1:
The lock device is designed with universal mounting options that can accommodate various door types, thicknesses, and frame configurations. The system includes multiple mounting positions, adjustable components, and versatile engagement mechanisms that function across diverse door installations, making the same lock suitable for different home settings without requiring custom modifications.

AI summary
A door lock system includes a first component mounted on one side of a door and a second component mounted on the opposite side. The system features a structure that mechanically connects the two components, designed to pass through the gap between the closed door and its frame. Additionally, the system incorporates a communication link between the first and second components.
