Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional mobile communication terminals require users to manually select their own number for each call, which is cumbersome, especially when communicating with the same party multiple times, as the terminal lacks automatic selection and updating of the appropriate number based on the intended use.

Innovation Solution

A mobile communication terminal with a number information memory, call origination directing means, judgment means, retrieval means, and first call origination means that automatically selects and updates the appropriate own number for outgoing calls based on the registered number information and intended use, eliminating the need for manual selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a portable wireless terminal registers multiple own telephone numbers in a UIM card and requires manual selection for each call, then the terminal can communicate using different numbers for different purposes, but the operation becomes bothersome and time-consuming

Engineering Contradiction:

Improveability to use different own numbers for different purposesVSAvoidmanual selection operation for each call

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary action by automatically determining and setting the own number before a call is made. The judgment means pre-judges which own number should be used based on the other-party number and call direction, eliminating the need for manual selection at call time. This resolves the contradiction by maintaining versatility while removing the bothersome manual operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminal performs self-service by automatically selecting and using the appropriate own number without user intervention. The control section autonomously determines which number to use based on stored number information and call direction, making the system self-sufficient and eliminating the need for manual selection operations.

Inventive Principle:

Principle #25Self-service

2Reliability

If the terminal requires selecting the same own number for repeated calls to the same party, then the terminal maintains number consistency, but the repeated manual selection becomes cumbersome

Engineering Contradiction:

Improvenumber consistency for repeated callsVSAvoidtime spent on repeated manual selection

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary determination of the own number before each call based on the other-party number and call direction. This pre-judgment ensures consistent number selection for repeated calls to the same party while eliminating the need for manual selection, thus resolving the time loss issue while maintaining reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from the number information memory to automatically select the appropriate own number. The judgment means references previously stored number information and call direction data to determine the correct own number, creating a feedback loop that ensures consistency without manual intervention and eliminates time loss.

Inventive Principle:

Principle #23Feedback

3Extent of automation

If the terminal stores number information mapping own numbers to other-party numbers, then the terminal can automatically retrieve the correct own number, but the device complexity increases

Engineering Contradiction:

Improveautomatic own number selectionVSAvoidnumber information storage and processing structure

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The number information memory serves multiple functions: it stores the mapping between own numbers and other-party numbers, provides reference data for the judgment means, and enables automatic retrieval operations. This multi-functionality reduces the need for separate dedicated components, thereby achieving automation while minimizing the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The number information memory acts as an intermediary between the call origination directing means and the retrieval means. It stores and mediates the relationship between own numbers and other-party numbers, enabling automatic retrieval without requiring complex direct connections between other components. This intermediary structure achieves automation while keeping complexity manageable.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A cellular phone 100 performs an own number extracting process via Step SA3, when a call origination operation is performed. In the own number extracting process, when an own number corresponding with an other-party number of the call recipient is registered in an address book storing section 14a, the corresponding own number is extracted from an own number storing section 14b. Then, the cellular phone 100 performs a call origination own number setting process via Step SA4. In the call origination own number setting process, when the own number extracted in the own number extracting process and the call origination own number stored in the call origination own number storing section 14c match, the extracted own number is set to the call origination own number. At Step SA5, the call is originated to the other-party number using the set call origination number.
