Base Unit Display System for Caller Information Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems do not provide sufficient additional information to called parties beyond the caller's telephone number and name, limiting the ability to display relevant details such as messages, dates, and times of calls.
Innovation Solution
A system comprising a base unit device with a microprocessor, Ethernet port, telephone port, transceivers, and antennas, along with a display unit featuring a liquid crystal display and keys, allows for the retrieval and display of additional information like caller names, messages, dates, and times on called party devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only basic caller ID information is displayed, then device complexity is reduced, but information completeness deteriorates
Solution Approach 1:
The system divides the information display function into two separate units: a base unit that collects and processes call information (ANI, CNAM, messages, dates, times) and a display unit that presents the information to the user. This segmentation allows the display unit to remain simple while the base unit handles the complexity of information gathering and management, thereby improving information completeness without significantly increasing display unit complexity.
Solution Approach 2:
The base unit acts as an intermediary between the telephone network and the display unit. It retrieves additional information from the network, processes it, and transmits it to the display unit. This intermediary approach enables the display unit to access comprehensive call information without needing to directly interface with complex network systems, thus maintaining simplicity while improving information completeness.
2Adaptability or versatility
If additional information is displayed, then user satisfaction is improved, but processing requirements increase
Solution Approach 1:
The base unit performs preliminary actions by collecting, validating, and organizing call information (ANI, CNAM, messages, dates, times) before it reaches the display unit. This pre-processing reduces the computational burden on the display unit, allowing it to focus on presenting information to the user. As a result, the system can provide comprehensive information that improves user satisfaction without overloading the display unit's processing capabilities.
3Productivity
If real-time information is provided, then communication effectiveness is improved, but system complexity increases
Solution Approach 1:
The system merges the information collection, processing, and display functions into a coordinated two-unit system. The base unit and display unit work together as an integrated system, with the base unit handling data acquisition and the display unit handling presentation. This merging of functions across two units enables real-time information provision that improves communication effectiveness while distributing system complexity across both components rather than concentrating it in one device.
