Door Lock Nesting Resilient Component in Casing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door locks, including mechanical combination locks, are vulnerable to unauthorized access due to ease of drilling through the door rather than the lock, and users may inadvertently reveal their codes/passwords, compromising security.
Innovation Solution
A mechanical combination door lock design featuring an inner door assembly with a locking assembly casing that houses the positioning resilient component, requiring intruders to break both the door and the lock to access it, and a mechanism that prevents code rings or buttons from being manipulated without proper authorization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the positioning resilient component is exposed in the mounting space, then the door lock can be operated easily, but the positioning resilient component becomes vulnerable to drilling attacks through the door
Solution Approach 1:
The positioning resilient component is nested inside the locking assembly casing, which is mounted within the mounting space of the door. The controlling component extends through the door to allow operation from either side, while the critical resilient component remains protected within the casing structure, preventing direct access via drilling through the door.
Solution Approach 2:
The locking assembly casing serves as an intermediary structure that houses the positioning resilient component. This casing acts as a protective barrier between the resilient component and potential drilling attacks through the door, while still allowing the controlling component to transmit operational forces to unlock the mechanism.
2Ease of operation
If the code rings or password buttons are left displayed after unlocking, then the door lock provides convenient access, but the unlocking code/password is exposed to unauthorized users
Solution Approach 1:
The controlling component is designed to dynamically return to its initial position after being actuated. When the door is unlocked, the controlling component automatically resets to its original configuration, which conceals the code rings or password buttons, preventing unauthorized users from reading the unlocking information.
Solution Approach 2:
Instead of maintaining the code display in a fixed visible state for convenience, the system inverts the approach by automatically concealing the code after use. The controlling component's return to its initial position actively hides the unlocking information, making unauthorized access difficult while still providing convenient operation for authorized users.
3Ease of manufacture
If the door structure is weaker than the mechanical combination lock, then the door assembly is easier to manufacture, but intruders can drill through the door to reach and manipulate the locking mechanism
Solution Approach 1:
The locking assembly casing is nested within the mounting space of the door, creating a layered structure. This nesting arrangement ensures that even if the door itself is drilled through, the locking assembly casing provides an additional barrier that protects the positioning resilient component and prevents direct manipulation of the locking mechanism.
Solution Approach 2:
The locking assembly casing acts as an intermediary protective layer between the door structure and the critical locking components. This intermediary structure shields the positioning resilient component from drilling attacks through the door, allowing the door itself to remain structurally simpler while maintaining overall security.
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
Enhances security by protecting the positioning resilient component within the locking assembly casing, making it harder for intruders to unlock the door and ensuring the lock remains secure even when the door is struck, while also preventing accidental code exposure.
Implementation Method 1
The reset resilient component is connected to the controlling component and configured to drive the controlling component to protrude out of the indoor handle
Implementation Method 2
The positioning resilient component is mounted on the protecting tube, located in the locking assembly casing, and configured to switch the door lock between a locked state and an unlocked state

AI summary
A door lock has an inner door assembly, an indoor doorknob assembly, and an outdoor doorknob assembly. The inner door assembly has a locking assembly casing. The indoor doorknob assembly has a positioning resilient component located in the locking assembly casing and configured to switch the door lock between a locked state and an unlocked state. The door is provided with enhanced protection by enclosing the positioning resilient component in the locking assembly casing, so the safety is further improved.
