Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electronic devices store original and edited contents in a 1:1 ratio, leading to excessive storage space usage and potential leakage or damage of original contents.

Innovation Solution

Storing original contents in a secure memory area and edited contents with metadata in a general memory area, associating them with access information, allowing non-destructive editing and minimizing storage space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If original contents and edited contents are stored in a 1:1 matching manner, then each edited content can be properly managed, but storage space is excessively occupied

Engineering Contradiction:

Improveedited content managementVSAvoidstorage space

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

Multiple edited contents that share the same original content are merged by storing only one copy of the original content. The system stores the original content once and creates references/links to it from multiple edited contents, eliminating redundant storage while maintaining the ability to manage each edited content independently.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The original content stored in secure area serves multiple purposes simultaneously - it acts as the source for multiple different edited contents. This multi-functional original content reduces the need to store separate originals for each edited version, optimizing storage space while preserving non-destructive editing capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If original contents are accessible to users, then users can directly access and use them, but they may be leaked or damaged

Engineering Contradiction:

Improvecontent accessibilityVSAvoidcontent security

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The storage system is segmented into two distinct areas: a secure area for storing original contents with restricted access, and a general area for storing edited contents with user access. This segmentation allows users to access and operate with edited contents freely while the original contents remain protected in the secure area, eliminating the security risk while maintaining ease of operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Edited contents serve as an intermediary layer between users and original contents. Users interact with edited contents in the general area, which contain all necessary editing information and metadata. This intermediary structure allows users to access and manipulate content without directly accessing the secure original contents, thus preventing leakage or damage while maintaining full operational capability.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method and a device are provided. The device includes a camera module, a communication module, a memory, and a processor operatively coupled to the camera module, the communication module, and the memory, wherein the processor is configured to acquire a first content through the camera module or the communication module, generate a second content by editing the first content, based on a user input, store the acquired first content in a secure area of the memory, and store the second content including metadata corresponding to the second content and first content access information corresponding to the first content in a general area of the memory, and the first content access information associates the first content with the second content.
