Indoor Positioning Bookmark System for Automated Elevator Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current elevator systems require manual operation of control panels for issuing elevator calls, which does not account for the user's presence or purpose within a building, leading to inefficient use of passageways.
Innovation Solution
A method utilizing indoor positioning information to determine a user's location and activate bookmarks, which include specific locations and functions for operating passageways, allowing for automatic control of elevator systems based on user presence and intended destinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation of elevator control panels is used, then the system is simple to operate, but the passageway operation efficiency deteriorates
Solution Approach 1:
The system automatically detects user presence via indoor positioning information and activates bookmarks without manual intervention. The passageway system serves itself by autonomously determining user location, comparing it with bookmark locations, and executing appropriate operations, eliminating the need for users to manually operate control panels while maintaining simplicity.
Solution Approach 2:
Bookmarks are pre-configured at specific locations within the structure with predetermined passageway operations. When a user approaches a bookmark location, the system has already prepared the appropriate operation, enabling immediate automated response without requiring manual input from the user, thus improving efficiency while keeping the interface simple.
2Productivity
If automated bookmark activation based on positioning is implemented, then passageway operation efficiency improves, but device complexity increases
Solution Approach 1:
The bookmark system serves multiple functions: it stores location information, defines passageway operations, triggers automated responses, and manages user preferences. By consolidating these functions into a single bookmark mechanism, the system achieves high automation efficiency without proportionally increasing complexity, as one component performs diverse roles.
Solution Approach 2:
The bookmark acts as an intermediary between the indoor positioning system and the passageway control system. Instead of directly complex interactions between positioning data and control commands, the bookmark serves as a pre-configured mediator that simplifies the automation logic, reducing overall system complexity while maintaining high productivity.
3Reliability
If manual elevator call issuance is used, then the system is reliable and easy to understand, but adaptability to user needs deteriorates
Solution Approach 1:
The system continuously receives indoor positioning information as feedback about user location and compares it with bookmark locations. This feedback loop enables the system to adaptively determine when and where to activate bookmarks, providing versatile response to different user needs while maintaining reliable automated operation through consistent positioning data monitoring.
Solution Approach 2:
The system dynamically adjusts passageway operations based on real-time user positioning data. Instead of static manual calls, the bookmark activation system adapts its behavior according to the user's current location and movement patterns, enabling versatile response to varying user needs while maintaining operational reliability through automated consistency.
Data Source
AI summary
Indoor positioning information is received for positioning a user within a structure including at least one passageway and one or more bookmarks, a bookmark including a location of the bookmark within the structure, and a function for operating the passageway, when the bookmark is activated. Location of the user is determined and compared with the locations of the bookmarks. At least one bookmark is determined to be activated and activated, on the basis of the correspondence of the user's location and the locations of the bookmarks. Current operational state and future operational state of the passageway are determined for controlling the passageway from the current operational state towards the future operational state that is determined on the basis of the activated bookmarks. The controlling is performed, when the current operational state and the future operational state are different.
