Elevator User Preference Association System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Elevator systems lack the ability to personalize building actions based on individual user preferences, leading to inefficient use of resources and user experience, as they primarily focus on access authorization and destination calls without considering user-specific settings for environmental and service preferences.
Innovation Solution
An elevator system that identifies passengers using information from a database to send personalized instructions to building components such as temperature, lighting, multimedia, and service appliances, allowing for tailored preparations of spaces like restaurants or gyms before the user arrives, using an elevator control unit and building control unit in conjunction with a profile database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elevator systems only perform basic access authorization and destination calls, then the system complexity remains low, but the user experience and resource allocation efficiency deteriorate
Solution Approach 1:
The elevator control system is enhanced to perform multiple functions beyond basic access authorization and destination calls. It now includes user identification, preference retrieval from database, determination of personalized building actions, and communication with building components. This multi-functionality improves user experience while managing system complexity through integrated control.
Solution Approach 2:
The system performs preliminary actions by identifying users before elevator boarding, retrieving their preferences in advance, and preparing personalized building actions (such as adjusting temperature, lighting, or pre-ordering food) before the user arrives at their destination. This advance preparation enhances user experience without requiring complex real-time adjustments.
2Ease of operation
If personalized building actions are implemented for each user, then user experience is improved, but energy consumption and resource usage increase
Solution Approach 1:
The system determines and prepares personalized building actions in advance based on user preferences stored in the database. By preparing actions preliminarily (such as pre-adjusting environmental settings or pre-ordering services), the system avoids unnecessary energy consumption that would occur with continuous or reactive adjustments, while still providing personalized user experience.
Solution Approach 2:
The system uses stored user preference data to automatically determine appropriate building actions without requiring continuous user input or manual adjustment. This self-service approach optimizes resource usage by activating personalized features only when needed, based on pre-stored preferences, rather than maintaining all features continuously active.
3Adaptability or versatility
If user preferences are stored and processed in real-time, then personalized service is achieved, but data processing time and system response time increase
Solution Approach 1:
User preferences are retrieved and processed in advance from the database before the user reaches their destination. By performing data retrieval and processing preliminarily, the system prepares personalized building actions ahead of time, minimizing real-time processing delays and ensuring quick response when the user arrives.
Solution Approach 2:
The system replaces complex real-time mechanical or manual preference adjustment mechanisms with automated electronic data retrieval and processing. By using database storage and electronic communication between control units, the system achieves rapid access to user preferences without the time delays associated with manual configuration or complex real-time sensing.

AI summary
A user (270) can be detected and identified at or near an elevator installation (240). A record (252) for the user (270) can be read from a database (250), and based on information in the record (252), a personalized building action can be performed for the user (270). A portion of the building (210) can thus be "prepared" for the user (270).
