Touch-Sensitive Destination Call Device for Elevator Floor Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems face inefficiencies in destination call input, including slow operation, high error rates due to decimal numeric keypads, poor information provision to users, and limitations in handling three-digit floor numbers, especially in high-rise buildings and portable devices.
Innovation Solution
A touch-sensitive destination call-giving device with a sliding indicator that allows users to select floors by moving a touching point in opposite directions on a display, enabling quick and simple floor selection, reducing errors, and accommodating access control, suitable for both large and small displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a decimal numeric keypad is used for floor selection, then any floor number can be entered, but the operation becomes slow and error-prone
Solution Approach 1:
The floor selection interface is segmented into individual floor buttons arranged vertically, each representing a specific floor. This allows users to select floors by simply tapping the corresponding button rather than sequentially entering multiple digits, dramatically reducing selection time while maintaining the ability to access any floor in the building.
Solution Approach 2:
All possible floor options are prepared and displayed in advance on the interface. The system pre-arranges floor buttons in sequential order, so users can directly select their destination without performing any calculation or sequential digit entry, thereby eliminating delays associated with manual number composition.
2Adaptability or versatility
If a decimal numeric keypad is used for floor selection, then any floor number can be entered, but errors increase due to incorrect keying
Solution Approach 1:
The floor selection interface is segmented into individual floor buttons arranged vertically, each representing a specific floor. This allows users to select floors by simply tapping the corresponding button rather than sequentially entering multiple digits, dramatically reducing selection time while maintaining the ability to access any floor in the building.
Solution Approach 2:
The system provides visual feedback by highlighting or indicating the currently selected floor button. This immediate feedback mechanism allows users to verify their selection before confirmation, preventing erroneous floor selections and enabling quick correction of mistakes without system errors.
3Reliability
If information about destination floor is provided only after entry, then security is maintained, but user experience deteriorates
Solution Approach 1:
The system displays all available floor options and their corresponding information (such as floor numbers and names) in advance on the interface, allowing users to review and confirm their destination selection before actual elevator dispatch. This preliminary information provision enhances user experience while access control security is maintained through the requirement of explicit user confirmation or authentication for actual floor access.

AI summary
The invention relates to a destination call-giving device (1) for giving destination calls in an elevator system, which comprises means available to a user for selecting a destination floor from a plurality of floors that are in a certain sequence, and an output for communicating the selected destination floor to the control system of the elevator system, which means for selecting a destination floor comprise a touch-sensitive display (3) forming a user interface for presenting to the user information related to the selection of a destination floor and for receiving the input of the user. The destination floor is arranged to be selectable by the user from the aforementioned plurality of floors by moving a touch-sensitive point on a touch-sensitive display (3). The invention also relates to an elevator system, and to a method for giving a destination call, and to a computer program product.
