Electronic Door Strip for Integrated Apartment Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems require residents to manually unlock both the residence and apartment doors, and installation is complicated due to the separation of intercom systems and electric locks, which are often located at different distances from the apartment doors.
Innovation Solution
An integrated access control system with an electronic door strip that combines intercom equipment and electric locks, allowing residents to unlock both doors from within their apartments, and simplifies installation by integrating all components into a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control units are used for residence door and apartment door, then each door can be controlled independently, but the installation complexity increases and the system becomes more complicated
Solution Approach 1:
The patent combines the control unit with the intercom system into a single integrated device. The control unit includes a microprocessor that can both communicate with the intercom system and control the electric lock, eliminating the need for separate control units for the residence door and apartment door. This integration maintains independent door control capability while significantly reducing installation complexity.
2Device complexity
If the control unit is housed within the electric lock casing, then the system structure is simplified, but the intercom system must be located elsewhere in the apartment requiring complex interfacing
Solution Approach 1:
The patent merges the control unit and intercom system into a single integrated device that is installed at the apartment door. This eliminates the need for separate housing locations and complex interfacing between distant components. The integrated device includes all necessary components (microprocessor, intercom interface, lock control) in one unit, making installation straightforward.
3Shape
If the intercom system is located away from the apartment door, then the door structure is simplified, but the interfacing becomes difficult and installation is not straightforward
Solution Approach 1:
The patent integrates the intercom system directly with the control unit at the apartment door location. This eliminates the need for long-distance interfacing between separately located components. The integrated design maintains door structure simplicity while making installation straightforward, as all components are housed in one unit installed at the door.
4Ease of operation
If a single integrated electronic door strip is used, then installation is simplified and operation is easier, but all components must be integrated into one unit
Solution Approach 1:
The patent integrates multiple components (control unit, intercom system, electric lock control, touch screen interface) into a single electronic door strip. While this creates a multi-component integrated unit, the integration is achieved through a modular design where components communicate via standard interfaces, making the overall system easier to install and operate compared to separate distributed components.
