Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If lossless video compression is used in SSD data compression solutions, then data integrity is maintained, but real-time video processing capability is not supported

Engineering Contradiction:

Improvedata integrityVSAvoidreal-time video processing capability

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent merges video transcoding functionality directly into the SSD controller, combining storage operations with video processing capabilities. This integration allows the SSD to perform both data storage and real-time video transcoding operations, resolving the contradiction between maintaining data integrity and enabling real-time processing.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The SSD controller is designed to perform multiple functions: traditional data storage/compression and video transcoding. By making the storage device universal and capable of handling both generic storage tasks and specific video processing tasks, the system achieves both data integrity and real-time video processing capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If video transcoding functionality is added to digital video recording devices, then user experience and performance are enhanced, but device complexity increases

Engineering Contradiction:

Improvevideo processing capabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of adding separate video processing hardware, the patent combines video transcoding functionality into the existing SSD controller. This merging approach enhances video processing capability while avoiding the increase in device complexity that would result from adding separate dedicated video processing units.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The SSD controller is designed as a universal component that handles both storage operations and video transcoding. This multi-functionality allows the device to achieve enhanced adaptability and versatility without requiring additional specialized hardware, thereby controlling device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If HDD is used for DVR storage, then cost is reduced, but power consumption and reliability are worsened

Engineering Contradiction:

ImprovecostVSAvoidpower consumption

Core Design Contradiction:

Ease of manufactureVSUse of energy by moving object

Solution Approach 1:

The patent changes the fundamental parameter of storage technology from magnetic (HDD) to solid-state (SSD). This parameter change results in dramatically reduced power consumption and improved reliability, while the integration of video transcoding functionality ensures that the system remains cost-effective by utilizing the SSD's full capabilities.

Inventive Principle:

Principle #35Parameter changes

4Use of energy by moving object

If SSD is used for DVR storage, then power consumption is reduced, but cost increases

Engineering Contradiction:

Improvepower consumptionVSAvoidcost

Core Design Contradiction:

Use of energy by moving objectVSEase of manufacture

Solution Approach 1:

The patent merges video transcoding functionality into the SSD controller, which adds value to the SSD investment. By combining storage and processing capabilities, the system maximizes the utilization of the SSD, making the higher initial cost more justifiable through enhanced functionality and performance.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The SSD is designed as a universal device that performs both storage and video transcoding functions. This multi-functionality increases the effective value and utility of the SSD, helping to offset the higher cost by providing additional capabilities that would otherwise require separate hardware components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An enhanced digital video recording device is provided to enhance digital video recording performance, features and user experience. The recording device has a processor and a storage unit, where the storage unit has multiple computer memory units, such as SSDs, HDDs, and video transcoder for transcoding video data in a data stream. The video transcoder interacts with a controller of the storage module to differentiate between video data packets and non-video data packets of the data stream based on one or more determination criteria. Responsive to data stream being video data stream, the video transcoder transcodes the data packets of the data stream. Responsive to the data packets being encrypted, the video transcoder obtains and/or generates encryption keys and decrypts the data packets. The video transcoder also periodically provides feedback data generated from transcoding process to enhance the transcoding operations.
