Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door lock systems face challenges in handling door handing and thickness adjustments, leading to improper installation and functionality issues, and lack effective protection and sealing mechanisms for electronic components.
Innovation Solution
A door lock system with a toolless handing assembly and self-adjusting spindles that can be easily set and reset for left or right handing, and automatically adjust to different door thicknesses, along with reinforced wiring protection and sealing mechanisms to secure electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional door lock systems use fixed spindles, then the installation process is simple, but the system cannot adapt to different door thicknesses and handing configurations
Solution Approach 1:
The patent implements dynamic spindles that can automatically adjust their position along the lock axis based on door thickness. The spindles include adjustment mechanisms with springs and cam surfaces that allow automatic adaptation to different door configurations without requiring manual intervention or complex tooling procedures.
Solution Approach 2:
The spindle adjustment mechanism is designed to self-adjust to the correct position based on the door thickness. When the lock body is installed, the spindles automatically move to their proper positions through spring-loaded mechanisms and cam surfaces, eliminating the need for manual adjustment by the installer.
2Reliability
If electromechanical locking systems include electrical hardware mounted on both door surfaces, then the locking functionality is enhanced, but the electronic components become vulnerable to breaches and environmental conditions
Solution Approach 1:
The patent implements a nested housing structure where an inner housing containing electronic components is positioned within an outer housing. The inner housing is secured to the backplate with fasteners accessible only from the interior side, creating a protected nested configuration that shields electronic components from exterior environmental factors and potential breaches.
Solution Approach 2:
The backplate serves as an intermediary element that provides a secure mounting surface between the inner and outer housings. It anchors the inner housing with concealed fasteners and provides a sealed interface, acting as a mediator that protects electronic components while maintaining structural integrity and environmental sealing.
3Productivity
If the lock body is mounted without centering adjustment, then the installation process is faster, but the lock body may be improperly positioned on doors of varying thickness
Solution Approach 1:
The spindle adjustment mechanisms are designed to automatically center the lock body on the door during installation. As the spindles adjust to different door thicknesses, they self-center the lock body through symmetric spring-loaded mechanisms and cam surfaces, eliminating the need for manual centering adjustment while maintaining precise positioning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures universal installation and reliable operation by accommodating various door configurations and securely protects electronic components from breaches and environmental conditions.
Implementation Method 1
a spring configured to bias the disc toward a first position
Implementation Method 2
the first spindle and the second spindle exert equal and opposite forces on the lock body
Data Source
AI summary
A door lock system that adjusts to doors of different thicknesses. The door lock system may include self-adjusting spindles that engage and center a lock body in a door. The spindles may exert equal and opposing forces that center the lock body within the door and align the lock body with a latch.
