Mobile Elevator Control via Identification Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems require users to manually input floor selections using physical control panels, which can lead to incorrect entries and lack of additional functionality beyond basic operation.
Innovation Solution
A method utilizing mobile radio devices with software applications that receive floor-specific identification codes from transmitting units, allowing users to send travel requests to a remote server, which forwards the requests to the elevator control device, thereby enabling mobile device operation of elevator systems and providing additional features like information display and secure data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical control panels are used for floor selection, then users can operate the elevator system, but incorrect entries may occur and additional functionality is limited
Solution Approach 1:
The mobile device serves multiple functions: it acts as a control panel for floor selection, provides navigation assistance, displays building information, and enables communication with the elevator system. This multi-functional approach replaces the single-function physical control panel while adding versatility.
Solution Approach 2:
The patent replaces the mechanical physical control panel with a software-based mobile device interface. The mobile device uses radio frequency communication to interact with the elevator system, eliminating the need for physical button presses and reducing human error in floor selection.
2Adaptability or versatility
If mobile devices are integrated with elevator systems, then additional functionalities and information are provided, but system complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary between the mobile device and the elevator control system. The server handles communication protocols, data processing, and coordination, simplifying the integration complexity while enabling advanced functionalities like trip planning and building information display.
Solution Approach 2:
The system is divided into separate functional modules: the mobile device for user interaction, the server for data processing and coordination, and the elevator control system for execution. This segmentation allows each component to be developed and maintained independently, reducing overall system complexity.
3Ease of operation
If floor-specific identification codes are transmitted, then automatic floor identification is achieved, but data transmission requirements increase
Solution Approach 1:
The patent uses compact identification codes that encode floor information in a condensed format. By changing the representation parameters of floor data (using coded identifiers instead of detailed descriptions), the system achieves automatic floor identification while minimizing data transmission volume.
