Single Button Call System Using Press Timing for Distinct Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing call button systems with a single push button cannot effectively differentiate between multiple types of notifications, such as safe and unusual events, requiring multiple buttons for distinct notifications.
Innovation Solution
An information processing system that uses a single operation terminal to transmit signals, where the type of notification is determined by the time period of the signal reception, allowing for the output of different notification information based on whether the signal is received within a predetermined first time period or a second time period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single push button is used in the call button system, then the device complexity is reduced and ease of operation is improved, but the ability to provide multiple types of notifications is lost
Solution Approach 1:
The patent applies parameter changes by utilizing the timing parameter of button presses to differentiate between multiple notification types. The notification determination unit analyzes the time interval between button press events to determine whether to generate a first notification (unusual event) or a second notification (meal completion), thereby enabling a single button to provide multiple notification functions without increasing device complexity
2Adaptability or versatility
If two call buttons are used to provide both positive and negative notifications, then the notification versatility is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent implements universality by designing a single call button that can perform multiple functions. The notification determination unit distinguishes between different notification types (unusual events and meal completion) based on the timing of button presses, allowing one button to replace what would traditionally require two separate buttons, thereby reducing device complexity while maintaining notification versatility
3Measurement precision
If two call buttons are used to differentiate between safe and unusual events, then the measurement precision of event type is improved, but the ease of operation and device complexity worsen
Solution Approach 1:
The patent uses parameter changes by leveraging the temporal parameter (time interval between button presses) to achieve accurate event type differentiation. The notification determination unit compares the elapsed time since the previous button press against a threshold to precisely distinguish between unusual events (short interval) and meal completion (long interval), maintaining high measurement precision while simplifying operation to a single button

AI summary
An information processing system includes: a receiver that receives a signal transmitted by a call button including a push button, and a communicator which transmits the signal outside in response to detection of an operation performed on the push button by a user; and an outputter that outputs (i) first notification information, when the signal is received in a first time period within a predetermined period, and (ii) second notification information different from the first notification information, when the signal is received in a second time period within the predetermined period which is different from the first time period.
