Elevator Car Digital Marker for Dynamic Directory Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional elevator systems lack the ability to provide passengers with dynamic and detailed information about the floors they are traveling to, as the static car operating panels do not offer real-time updates or interactive content, making it difficult for users to navigate and access information about tenants, services, and other floor-specific details.
Innovation Solution
Incorporating a digital readable marker on the car operating panel that connects to a digital storage system, allowing users to scan or read the marker with a device to access and display directory information, including augmented reality and interactive elements, which can be updated dynamically based on changes in the building.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standardized user interface components are used, then manufacturing and maintenance costs are reduced, but user experience and information provision capabilities are limited
Solution Approach 1:
The patent uses a digital readable marker (QR code or barcode) that contains encoded information about floor directories. This digital copy approach allows the same physical marker to provide different information dynamically through digital content, eliminating the need for multiple physical interface designs while maintaining rich information delivery capabilities.
Solution Approach 2:
The patent replaces traditional mechanical information display methods (physical signs, printed directories) with a digital system. Users scan the marker with their devices to access directory information, substituting the mechanical display system with an optical-digital interface that provides flexible, updatable information without physical changes.
2Device complexity
If static car operating panels are used, then device complexity is reduced, but information dynamism and interactivity are lost
Solution Approach 1:
The digital readable marker serves as a compact digital copy of floor directory information. Instead of displaying all information statically on the panel, the marker encodes references to dynamic digital content that users can access on demand, maintaining panel simplicity while enabling information dynamism through digital replication.
Solution Approach 2:
The patent introduces a digital readable marker as an intermediary between the static panel and dynamic information. The marker itself remains simple and static, but it mediates access to dynamic directory information through digital storage systems, separating the physical interface from the information content.
3Reliability
If physical changes are made to update directory information, then information accuracy is maintained, but manufacturing and installation time increase
Solution Approach 1:
The system uses digital copying of directory information into a readable marker format. When floor directory information changes, only the digital content needs to be updated and re-encoded into the marker, rather than physically replacing signs or panels. This maintains information accuracy through controlled digital updates while enabling rapid deployment.
Solution Approach 2:
The patent transforms the static physical information system into a dynamic digital system. The readable marker can be updated remotely and instantly reflects current floor directory information, allowing the system to adapt quickly to building changes without physical intervention, thereby maintaining accuracy while improving update speed.

AI summary
Elevator systems having an elevator car located within an elevator shaft, the elevator car moveable between a plurality of floors of a building, a car operating panel located within the elevator car and having a plurality of buttons operable for selection of a destination floor of the plurality of floors, a digital readable marker located within the elevator car that is at least one of scannable and readable by a user device, and a digital storage system having information stored thereon, the information including directory information, wherein the directory information includes information associated with the floors selectable by operation of the plurality of buttons. When a user device scans or reads the digital readable marker, the digital storage system transmits the directory information to the user device so that the user device can display the directory information to a passenger.
