Modular Door Lock System with Expandable Function Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door locks are limited in functionality and cannot easily expand to include advanced features like crime prevention, fire detection, or home network interaction without replacing the entire lock, which is costly and inefficient.
Innovation Solution
An electronically controlled door lock system with a multi-purpose interface device that allows for the attachment of function expanding devices, enabling the addition of features such as fingerprint authentication, camera functions, and home network integration without replacing the lock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire door lock is replaced to add new functions, then the functionality and security performance are improved, but the cost and complexity increase significantly
Solution Approach 1:
The door lock system is divided into a base lock unit and separate functional modules (fingerprint module, camera module, fire detection module, home network module). Each module can be independently selected and attached, allowing functionality expansion without replacing the entire lock system.
Solution Approach 2:
The base lock unit is designed with a universal interface that can accommodate multiple different functional modules. The control unit can manage various functions through a unified architecture, making the system adaptable to different security and convenience requirements.
2Adaptability or versatility
If the entire door lock is replaced to add new functions, then the functionality and security performance are improved, but the cost increases
Solution Approach 1:
The system separates expensive electronic function modules from the base lock mechanism. Users only need to invest in the modules they require, rather than paying for a complete new lock system, significantly reducing overall cost.
Solution Approach 2:
The system allows dynamic configuration where users can start with basic functionality and add modules progressively as budget and needs permit. The modular architecture enables flexible scaling from simple to complex configurations.

AI summary
Disclosed is an easy-to-retrofit, electronically controlled door lock system designed to change or expand functions of a door lock without having to replace the door lock as a whole. The door lock system includes a door lock 100 for locking and unlocking a door in response to an input signal from a key means, the door lock having predetermined inherent functions, and a function expanding device 200 having additional functions other than the predetermined inherent functions of the door lock, the function expanding device being replaceably attached to the door lock.
