Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Storage management systems for recording content face challenges in managing limited storage space, often leading to the deletion of important programs, as they lack efficient methods to prioritize and reduce storage usage without disrupting delayed viewing functions.

Innovation Solution

A storage management system that selectively reduces the quality level of previously stored content based on priority or age, converting selected content to lower quality levels when storage is full, allowing users to identify programs for conversion and providing options for quality reduction to free up space for new content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the system deletes low priority programs to free storage space, then storage space is freed for new recordings, but important programs may be deleted

Engineering Contradiction:

Improvestorage spaceVSAvoidprogram retention

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The system changes the quality parameter of existing video programs from high quality to lower quality, which reduces the storage space occupied by these programs. This allows the system to free up storage space without deleting programs, thereby maintaining program retention while accommodating new recordings.

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If the system converts video quality to lower levels, then storage space is reduced, but video quality deteriorates

Engineering Contradiction:

Improvestorage spaceVSAvoidvideo quality

Core Design Contradiction:

Quantity of substanceVSManufacturing precision

Solution Approach 1:

The system dynamically adjusts video quality levels based on storage space availability. When storage is sufficient, videos are maintained at high quality. When storage becomes limited, the system selectively converts lower priority videos to lower quality levels, creating a dynamic adaptation to storage conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system applies different quality levels to different video programs based on their priority classification. High priority programs maintain high quality, while low priority programs are converted to lower quality, creating local quality variations across the video library.

Inventive Principle:

Principle #3Local quality

3Productivity

If the system prioritizes storage management, then storage efficiency is improved, but delayed viewing functions may be disrupted

Engineering Contradiction:

Improvestorage efficiencyVSAvoiddelayed viewing operation

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system automatically monitors storage space and performs quality conversion on low priority videos without requiring user intervention. This self-service mechanism ensures storage efficiency is maintained while the delayed viewing function continues to operate uninterrupted, as the system handles storage management autonomously.

Inventive Principle:

Principle #25Self-service

AI summary

A storage management system selectively reduces a quality level of previously stored content. When storage in the system is becoming full, selected content is converted to a lower quality or lower storage size, based at least one of priority or age. Such conversion is performed in a computing background to minimize interference with programs being currently viewed. A user interface provides a list of programs that are candidates for conversion. The user selects programs to be converted or deleted to create additional storage for the new programs.
