Elevator Operation Panel Non-Contact Detection Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-contact type elevator operation panels, users face difficulties in intuitively determining the correct proximity to the panel for operation, leading to a high likelihood of accidental contact, which is undesirable for hygiene and operation accuracy.
Innovation Solution
The elevator system incorporates an operation panel with an input determination unit to detect non-contact operations, an input information transmission unit to send detected information to the elevator control device, and a registration floor display processing unit that outputs an operation sound and changes button displays upon object approach, ensuring proper registration without physical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a non-contact type operation panel is used to prevent infectious diseases, then hygiene is improved, but users cannot intuitively determine the correct proximity for operation, leading to accidental contact
Solution Approach 1:
The operation panel provides immediate visual feedback by changing the displayed image when an object approaches within the operation distance. This feedback mechanism allows users to intuitively understand whether they are at the correct proximity for non-contact operation, eliminating the uncertainty about proper spacing while maintaining hygiene through contactless interaction.
Solution Approach 2:
The operation panel changes the color or brightness of the displayed image in response to object approach. This visual transformation provides clear indication of the operation state, enabling users to intuitively grasp the correct proximity without physical contact, thus resolving the contradiction between hygiene and ease of operation.
2Reliability
If a non-contact operation detection method with a certain threshold time is used, then erroneous registration is prevented, but users do not know whether the operation is detected, leading to finger contact
Solution Approach 1:
The system provides real-time visual feedback by changing the displayed image when an object approaches within the operation distance, before the threshold time elapses. This immediate feedback informs users that their non-contact operation is detected, preventing accidental finger contact while maintaining reliable error prevention through the threshold time mechanism.
Solution Approach 2:
The operation panel changes the display image in advance before the threshold time period completes, providing preliminary feedback to the user that the operation is being detected. This preliminary action ensures users know their non-contact input is registered, eliminating the need to touch the panel while maintaining accurate error prevention.
3Measurement precision
If the button is turned on after continuous approach for a certain time, then registration accuracy is improved, but operation time is extended and user patience is reduced
Solution Approach 1:
The system performs a partial action by changing the display image immediately when the object approaches within the operation distance, providing preliminary feedback. The complete registration action occurs after the threshold time elapses. This partial action reduces perceived operation time and improves user experience while maintaining accurate registration through the full threshold time verification.
Solution Approach 2:
The display image changes in advance before the threshold time period completes, providing preliminary indication of the selected floor. This preliminary action gives users immediate visual confirmation of their selection, reducing perceived waiting time while the full threshold time mechanism ensures accurate registration and prevents erroneous input.

AI summary
Disclosed is an elevator including an operation panel capable of registering a destination floor with non-contact operation of a display panel, in which the elevator can perform an appropriate non-contact operation while preventing the display panel from being touched. The operation panel outputs an operation sound from a sound device when an input determination unit detects an approach of an object to the display panel. Then, when the input determination unit continuously detects the approach of the object for a predetermined time, the operation panel changes a display of the button displayed at a location where the approach of the object to the display panel is detected, and a registration floor display processing unit, when the input determination unit no longer detects the approach of the object, causes the display panel to display the destination floor allocated to the button as a registration floor.
