Communication Device Call Request Notification Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems do not effectively allow callers to notify others of their availability for casual conversations without bothering the recipient, as they lack the ability to distinguish between urgent and non-urgent calls and require manual confirmation methods.
Innovation Solution
A communication device with a receiver specification section and a control section that transmits call request information to the receiving device for a predetermined time period, allowing the caller to notify their availability without disturbing the recipient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a caller sends a confirmation e-mail in advance to check availability, then the caller can confirm the other party's convenience, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The system performs preliminary action by automatically sending call request notifications to the recipient before the actual call. The notification is sent in advance with a predetermined display time, allowing the recipient to prepare and decide whether to answer, thereby eliminating the need for manual confirmation emails while ensuring reliable availability checking.
Solution Approach 2:
The system implements self-service by automatically managing the entire notification process. The caller's terminal automatically transmits the call request notification to the recipient's terminal without requiring the caller to manually send confirmation emails. The system handles the timing, transmission, and automatic deletion of notifications, making the operation simple and convenient.
2Loss of information
If presence information is continuously updated and transmitted, then the caller's condition can be accurately informed to the other party, but the device complexity and energy consumption increase
Solution Approach 1:
Instead of continuously updating presence information, the system performs preliminary action by determining the caller's availability status in advance and transmitting this information through a call request notification. The notification includes essential information (caller's desire to talk and predetermined display time) without requiring continuous updates, thereby maintaining information accuracy while simplifying the system.
Solution Approach 2:
The system extracts only the essential information needed for the recipient to make a decision (caller's availability and call request intent) from the complete presence information. By transmitting only this extracted critical information through the call request notification, the system avoids the complexity of continuous presence information updates while still providing accurate availability information.
3Loss of time
If call request notification is displayed for a long time, then the recipient has sufficient time to respond, but it may bother the recipient with unnecessary disturbances
Solution Approach 1:
The system applies dynamics by making the notification display time flexible and predetermined rather than fixed or indefinite. The caller can set an appropriate display time based on their availability, allowing the notification to be displayed long enough for the recipient to respond but not so long as to cause unnecessary disturbance. The notification is automatically deleted after the predetermined time expires.
Solution Approach 2:
The system implements periodic action by automatically deleting the call request notification after a predetermined display time. This creates a natural cycle where the notification is displayed for an appropriate duration to allow recipient response, then automatically removed to prevent ongoing disturbance. The periodic deletion ensures the notification serves its purpose without becoming a nuisance.

AI summary
A communication device, including a receiver specification section which specifies a receiving communication device; a control section which transmits, to the receiving communication device specified by the receiver specification section, call request information used for outputting a call request notification and deleting the call request notification after a predetermined time period; a time period setting section which sets a time period during when the call request notification is output by the receiving communication device; a message setting section which sets a call request message; and a cancel instruction section which inputs a cancel instruction of the call request notification.
