Elevator Guidance Device Using Personalized Projection Signs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical transportation machine guidance methods fail to clearly guide users to their selected elevators, especially in crowded conditions where multiple arrows are indicated simultaneously, leading to confusion, and users may miss or forget the guidance information.
Innovation Solution
A vertical transportation machine guidance device and method that acquires user identification information, selects the appropriate elevator, and provides personalized route guidance signs using projection technology on the floor, ensuring each user can easily follow the sign to the selected elevator's landing entrance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple arrows are indicated simultaneously for users heading for the same destination floor, then guidance information is provided to all users, but users cannot easily recognize which arrow is indicated for themselves
Solution Approach 1:
The patent applies local quality by assigning distinct visual characteristics (different colors, patterns, or shapes) to guidance arrows based on individual user identification. Each user receives a guidance arrow with unique visual properties that match their designated indication mode, allowing them to easily recognize their own arrow among multiple simultaneous indications. This resolves the contradiction by maintaining comprehensive coverage while enabling clear individual identification.
2Device complexity
If guidance information is provided only at the security gate exit, then the guidance system is simple, but users may fail to notice or forget the guidance information during movement to the elevator hall
Solution Approach 1:
The patent applies preliminary action by providing guidance information at multiple strategic locations (security gate exit, elevator hall entrance, and near the elevator) before the user reaches the destination. This ensures that guidance information is reinforced at key moments, preventing users from forgetting or missing the instructions. The system maintains relative simplicity while significantly improving reliability through multi-point guidance provision.
3Device complexity
If a single indication mode is used for all users, then the guidance system is simple to implement, but users in crowded conditions cannot distinguish their own guidance arrow
Solution Approach 1:
The patent implements local quality by varying the visual characteristics of guidance arrows according to individual user identification. Each user is assigned a unique indication mode (different colors, patterns, or shapes) that makes their arrow distinguishable from others. This resolves the contradiction by enabling clear user-specific identification while maintaining systematic implementation through automated identification and assignment processes.

AI summary
There is provided an elevator guidance device 40 including an identification information acquisition unit 41 configured to acquire identification information for a user heading for an elevator hall, a selected elevator information acquisition unit 42 configured to acquire information on a selected elevator selected from a plurality of elevators as an elevator for the user identified to take, and a guidance indication unit 43 configured to indicate, in an indication mode associated with the user, a leading guidance sign on a route starting from a leading start position, at which leading of the user identified is started, to a landing entrance of the selected elevator, the leading guidance sign leading the user to the landing entrance of the selected elevator.
