Solution Overview

Problem

Modern telephones, including VoIP systems, lack the ability to provide detailed information and facilitate actions for calls in call lists beyond basic call data, making it difficult for users to differentiate between calls of varying importance and manage follow-up actions effectively.

Innovation Solution

The implementation of flags and actions on call lists, allowing users to categorize calls by pressing specific keys on a handset, adding indicators or reminders, and associating text messages with calls, enabling users to prioritize and manage calls more effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If modern telephones maintain basic call lists with telephone numbers, then the device complexity is low and ease of operation is high, but the ability to provide detailed information and facilitate actions for calls is insufficient

Engineering Contradiction:
Improvecall information detailVSAvoidcall list management complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments call management into distinct categories (flagged calls, recalled calls, text message associated calls) allowing users to organize calls by type and priority. This segmentation enables detailed information provision without overwhelming the user with all call data at once, resolving the contradiction between information detail and system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically updates call list entries based on user actions (pressing keys to flag, recall, or associate text messages) and automatically manages call states. This dynamic behavior allows the system to provide detailed information on-demand while maintaining simple basic operations, balancing information richness with operational simplicity.

Inventive Principle:
Principle #15Dynamics

2Productivity

If users receive many different types of telephone calls, then the productivity is high, but the ease of operation deteriorates due to difficulty in differentiating call importance

Engineering Contradiction:
Improvecall handling efficiencyVSAvoidcall prioritization ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent applies local quality by allowing users to mark specific calls with different attributes (flagged, recalled, text message associated) based on their individual importance and requirements. This enables users to differentiate call importance locally for each call entry, improving ease of operation while maintaining high productivity through efficient call management.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system provides visual feedback through icons and indicators next to call entries showing their status (flagged, recalled, text message associated). This feedback mechanism helps users quickly differentiate call importance and prioritize accordingly, enhancing both productivity and ease of operation by making call status immediately visible and actionable.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If flags and actions are added to call lists, then the ease of operation improves for call management, but the device complexity increases

Engineering Contradiction:
Improvecall categorization easeVSAvoidcall list feature complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by enabling a single call list entry to support multiple operations and attributes (flagging, recalling, text message association) simultaneously. This universal approach allows users to manage calls efficiently with multiple features integrated into one system, improving ease of operation while managing device complexity through unified call management architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present invention provides a mechanism for categorizing telephone calls and for providing special information about calls that appear on call lists maintained in a telephone. The invention provides for both providing an indication and for providing an action. When an entry on a call list is highlighted (in a conventional manner), pressing one key adds a flag to the entry on the call list to indicate that follow up action is required. Pressing a second key initiates an action such as attaching a reminder so that the user will be reminded to take action later. Pressing a third key will provide a text message balloon indicating information about the call. The flags and text messages can be added by either the called party or the calling party.
