Solution Overview

Problem

Conventional communication terminal devices require cumbersome operations to manage storage space by deleting unnecessary destination information when the storage device reaches capacity, leading to inefficient use of storage area.

Innovation Solution

A communication terminal device with a receiving unit, registration information storage unit, and searching unit that efficiently registers origination information as destination information by determining its existence in an external information supplying device, and only registers information satisfying a preset condition, thereby optimizing storage usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all origination information is registered as destination information without distinction, then the storage device fills up quickly requiring frequent deletions, but this approach ensures no useful information is lost

Engineering Contradiction:

Improveinformation retentionVSAvoidstorage management operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system automatically determines whether to register origination information by checking against external information supplying devices, eliminating the need for manual user judgment and operations. The terminal device performs self-service by autonomously filtering and selecting which information to retain.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system establishes a feedback mechanism by continuously checking whether origination information already exists in external information supplying devices before registration. This feedback loop prevents redundant storage operations and optimizes storage space utilization.

Inventive Principle:

Principle #23Feedback

2Quantity of substance

If the storage device capacity is increased to store all destination information, then no deletions are needed, but the device size and cost increase

Engineering Contradiction:

Improvestorage capacityVSAvoiddevice size

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The system extracts only the necessary destination information from received origination information by checking against external information supplying devices. Only information that cannot be obtained from external sources is stored locally, minimizing storage requirements while maintaining functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system dynamically changes the storage parameter by selectively registering only those origination information items that are not found in external information supplying devices. This parameter-based selection optimizes storage space utilization without requiring increased device capacity.

Inventive Principle:

Principle #35Parameter changes

3Quantity of substance

If manual deletion of unnecessary destination information is implemented when storage is full, then storage space is recovered, but user time and effort are consumed

Engineering Contradiction:

Improveavailable storage spaceVSAvoidtime for deletion operation

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The system performs preliminary action by proactively checking whether origination information exists in external information supplying devices before registration. This prevents unnecessary information from being stored in the first place, eliminating the need for future deletion operations and saving user time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system autonomously manages storage space by automatically determining which information to register and which to exclude, based on availability in external information supplying devices. This self-service approach eliminates the need for manual intervention in storage management.

Inventive Principle:

Principle #25Self-service

4Quantity of substance

If selective registration of origination information is implemented based on external information availability, then storage space is optimized, but the device complexity increases

Engineering Contradiction:

Improvestorage space utilizationVSAvoidregistration control mechanism

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The system uses external information supplying devices as intermediaries to determine whether local storage is necessary. By checking availability through these intermediary sources, the system optimizes storage space without requiring complex local decision-making mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)
