Press-Type Switch Input Unit for Occupied-Hand Message Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information storage systems require manual input with both hands, making it difficult to store and share brief information, especially in situations where hands are occupied, and they often necessitate accurate text input, which can be cumbersome and lead to forgotten information.
Innovation Solution
An information storage system with a plurality of press-type switches that allow input of on-signal or off-signal for message association, connected to a data server for communication, enabling simple message output and sharing, even with one hand, and including features for message deletion and urgency flag indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If text data is input using a touchscreen with both hands, then accurate information can be stored, but the operation becomes complex and difficult when hands are occupied
Solution Approach 1:
The input method is segmented into two distinct modes: voice input for accurate information storage and button input for simple operations. The voice recognition device handles the complex task of accurate text input, while the button device provides simple one-hand operation capability, resolving the contradiction between input accuracy and operation simplicity
Solution Approach 2:
The voice recognition device acts as an intermediary between the user and the information storage system. Instead of directly manipulating the touchscreen with hands, the user speaks commands that are converted into text data by the voice recognition device, eliminating the need for manual touchscreen operation while maintaining input accuracy
2Loss of information
If detailed text data is input accurately, then complete information is stored, but the input process becomes time-consuming and may be forgotten
Solution Approach 1:
The system performs preliminary action by automatically storing information in a draft state before final confirmation. When information is input via voice or button, it is immediately stored in the information storage device in a preliminary state, allowing users to review and confirm later without losing the information, thus preventing information loss while reducing immediate input time
Solution Approach 2:
The system provides feedback by notifying users of stored information and allowing confirmation or deletion. The notification device alerts users about stored information, and users can confirm or delete through simple button operations, ensuring information completeness while minimizing the time and effort required for final processing
3Measurement precision
If both hands are used for touchscreen input, then text data can be entered accurately, but the system becomes unusable when hands are occupied
Solution Approach 1:
The system achieves universality by supporting multiple input methods (voice recognition and button input) that can be used in different situations. The voice recognition device provides accurate text input when hands are free, while button input enables operation when hands are occupied, making the system adaptable to various usage scenarios without sacrificing input accuracy

AI summary
An information storage system and an information storage method allow necessary information to be stored in the proper amount with a simple operation for people to share the information. The system includes an input unit including a plurality of press-type switches each of which accepts input for an on-signal or an off-signal and a data server storing pieces of identification information each identifying a corresponding one of the switches and messages in association with each other and outputs, in response to input accepted by each of the switches, a corresponding one of the messages. The input unit transmits an on-signal or an off-signal and a piece of identification information to the data server. The data server receives the on-signal or the off-signal and the piece of identification information and extracts and outputs a message associated with the piece of identification information received together with the on-signal.
