Reception Information Retention Using Validity-Based Auto Deletion

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing information processing systems fail to delete reception information from memory after the validity period expires, leading to unnecessary storage.

Innovation Solution

An information processing apparatus and method that includes a processor to receive reception information with a validity period, store it, and automatically delete it from memory when the period expires.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If reception information is stored in memory without automatic deletion, then data availability is maintained, but memory storage is wasted after validity period expires

Engineering Contradiction:

Improvememory storageVSAvoiddata availability

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The system performs preliminary action by setting up an expiration time for reception information when it is stored. The memory management unit establishes a validity period and automatically deletes the information when this period expires, without requiring manual intervention or continuous monitoring. This resolves the contradiction by proactively managing storage space while ensuring data is available during its valid period.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If manual deletion of reception information is required, then data integrity can be controlled, but operational complexity increases

Engineering Contradiction:

Improvedata managementVSAvoidmanagement process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The memory management unit implements self-service by automatically monitoring the validity period of stored reception information and deleting it when expired. The system serves itself by establishing automatic deletion based on pre-set expiration times, eliminating the need for manual intervention. This resolves the contradiction by making data management easier while the automatic mechanism handles the complexity internally.

Inventive Principle:

Principle #25Self-service

3Duration of action of moving object

If reception information is kept indefinitely, then future access is possible, but storage efficiency decreases

Engineering Contradiction:

Improvedata retention periodVSAvoidmemory usage

Core Design Contradiction:

Duration of action of moving objectVSQuantity of substance

Solution Approach 1:

The system applies parameter changes by dynamically adjusting the retention period of reception information based on its validity period. Instead of indefinite storage, the memory management unit changes the state of stored data from permanent to temporary, with automatic deletion scheduled at expiration. This resolves the contradiction by optimizing memory usage while maintaining data access during the appropriate time window.

Inventive Principle:

Principle #35Parameter changes

AI summary

An information processing apparatus includes a memory and a processor configured to: receive reception information from a user and authentication information including a validity period which is determined on a per user basis and throughout which a transmission destination apparatus transmitting the reception information is available; store the reception information on the memory; and delete the reception information from the memory when the validity period expires.
