Elevator Landing Guidance Device Using Distinct Guide Sounds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator landing guidance systems rely on audio messages, which can be ineffective for users with linguistic differences and may become indistinguishable in crowded conditions due to voice mixing.
Innovation Solution
An elevator landing guidance device using guide sounds, such as electronic or buzzer sounds, to direct users to the correct elevator machine, with separate sound generators for each elevator and a hall operation panel to ensure clear guidance regardless of language or visual impairment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio messages are used for elevator landing guidance, then users who can understand audio content receive effective guidance, but users with linguistic differences cannot understand the guidance
Solution Approach 1:
The patent replaces the acoustic field (audio messages) with the optical field (visual display devices). Instead of using speakers to output audio guidance, the system uses display screens to show visual information including text in multiple languages and icons, thereby eliminating language barriers while maintaining guidance effectiveness.
Solution Approach 2:
The visual display device serves multiple functions: it displays text information in multiple languages, shows icon-based universal symbols, provides directional arrows, and can adapt its content based on the selected language. This multi-functional approach ensures broad adaptability across different user groups including those with linguistic differences, hearing impairments, or in noisy environments.
2Loss of information
If audio guidance is used, then guidance information can be provided to users, but in crowded conditions the voice is mixed with passenger voices and is hard to hear and distinguish
Solution Approach 1:
The patent substitutes the acoustic guidance system with a visual guidance system. Display devices are installed at elevator landings to show visual information instead of relying on audio messages. This replacement eliminates the problem of voice mixing in crowded conditions, as visual information remains clear and distinguishable regardless of ambient noise levels or passenger density.
3Adaptability or versatility
If multiple-language guidance service is provided using audio messages, then linguistic diversity is accommodated, but the data amount is increased
Solution Approach 1:
The visual display device provides multi-language support through a single unified interface. The system can switch between multiple languages and display both text and icon-based universal symbols. Icons serve as language-independent visual cues that convey meaning without requiring translation, thereby supporting linguistic diversity while maintaining efficient data usage compared to storing separate audio files for each language.

AI summary
Provided is an elevator landing guidance device including: a hall operation panel (2) provided on each of floors, which is configured to output a guide sound (A) for informing a position of the hall operation panel (2) and accept input of landing call registration; and a guide sound generator (3), which is provided to a landing of each of the floors for each of elevator machines, and which is configured to output a guide sound (B) for informing a position of the landing. When the landing call registration is input to the hall operation panel (2), the guide sound (B) is output from the guide sound generator (3) installed so as to correspond to one of the elevator machines, which is assigned to the landing call registration.
