Elevator Notification Speed Control by User Physical Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator notification systems fail to consider user attributes beyond language type, leading to suboptimal information delivery.
Innovation Solution
A notification control device that identifies user physical attributes such as age and disability status to adjust information provision speed and language, using cameras and microphones to gather data and control notification devices like displays and speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If notification information is provided at a fixed speed for all users, then the notification device is simple to operate, but the information delivery is not optimized for individual user needs
Solution Approach 1:
The notification control device dynamically adjusts notification speed based on detected user attributes. The system transitions from a static, fixed-speed notification mode to a dynamic mode where notification parameters are automatically modified according to user characteristics such as language type, age group, and disability status, resolving the contradiction between operational simplicity and adaptive capability
Solution Approach 2:
The notification control device automatically detects user attributes and adjusts notification parameters without requiring manual user input or configuration. The system performs self-service by autonomously identifying user needs and optimizing information delivery accordingly, maintaining ease of operation while achieving adaptability
2Adaptability or versatility
If the notification system considers multiple user attributes beyond language, then information delivery is more personalized, but the system complexity increases
Solution Approach 1:
The notification control device segments user attributes into distinct categories (language type, age group, disability status) and processes each category independently through dedicated detection mechanisms. This segmentation allows the system to handle multiple attributes without creating unmanageable complexity, as each attribute type can be detected and processed through separate functional modules
Solution Approach 2:
The notification control device is designed as a multi-functional system that can detect and respond to various types of user attributes using a unified control architecture. By creating a universal platform that handles multiple attribute types through integrated functions, the system achieves high adaptability while avoiding the complexity that would result from separate specialized systems for each attribute
3Adaptability or versatility
If notification speed is adjusted based on user physical attributes, then information delivery is more appropriate for the user, but additional detection devices are required
Solution Approach 1:
The notification control device merges the detection functions for multiple user attributes into a single integrated control unit. By combining language detection, age estimation, and disability status detection within one unified device, the system achieves notification speed adaptation based on physical attributes without requiring separate detection devices for each attribute type, thus reducing overall system complexity

AI summary
A notification control device includes an attribute identification unit configured to identify a physical attribute of a user who uses an elevator, and a notification control unit configured to control, based on the physical attribute identified by the attribute identification unit, a notification speed at which information is provided by a notification device installed in a car in which the user having the identified physical attribute is to ride.
