Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic door trim systems for elevator systems face reliability issues due to complex wiring defects, leading to partial or complete system failures, and require extensive cabling for data transfer and communication.
Innovation Solution
The implementation of a battery-driven wireless communication system using radio transmission technology, such as ZigBee, which connects the electronic door trim online to an access control system, eliminating the need for extensive wiring and allowing real-time monitoring and control of door status through wireless communication units, including mortise locks with integrated sensors and recognition devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive complex wiring with cables is used for data transfer and communication, then the electronic door trim system can be connected to the access control system, but the system reliability deteriorates due to wiring defects and errors
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless communication system. The electronic door trim communicates with the access control system via wireless signals, eliminating physical cables and connectors. This substitution removes the source of wiring defects and errors while maintaining full communication functionality, directly resolving the contradiction between system reliability and wiring complexity.
2Reliability
If battery-driven wireless communication is implemented, then wiring errors are eliminated and system reliability improves, but energy consumption increases due to battery operation
Solution Approach 1:
The electronic door trim employs periodic communication rather than continuous transmission. The wireless system activates only when door status changes occur (opening, closing, locking, unlocking), transmitting data at these discrete moments. This periodic action pattern significantly reduces battery energy consumption compared to continuous communication, while maintaining reliable real-time monitoring capability.
3Ease of manufacture
If the electronic door trim is operated offline with complex wiring, then extensive cabling is required, but the system operation becomes unreliable due to wiring defects
Solution Approach 1:
The patent replaces the mechanical wiring installation process with wireless communication technology. The electronic door trim establishes communication with the access control system through wireless signals, eliminating the need for complex cable routing, connector installation, and wiring integration. This substitution simultaneously improves installation simplicity and system reliability by removing the entire wiring infrastructure.
4Ease of operation
If wireless communication units are used for online connection, then the door trim can react online to the access control system, but additional battery load is incurred
Solution Approach 1:
The wireless communication unit operates in a periodic manner, activating only when door status changes occur. The system monitors door opening, closing, locking, and unlocking events, transmitting wireless communications only at these discrete moments rather than maintaining continuous online connection. This periodic operation pattern enables the door trim to react online to access control system commands while significantly reducing battery load compared to continuous communication.
