Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If large-language models (LLMs) are used to handle user queries and identify media items, then the system can process broad intent queries using world knowledge, but the computational cost and time consumption increase significantly

Engineering Contradiction:
Improveability to handle broad intent queriesVSAvoidcomputational efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system segments the query processing into two distinct paths: (1) LLM-based processing for broad intent queries that require world knowledge, and (2) structured query processing for specific media item retrieval. This segmentation allows each component to operate optimally within its designated scope, reducing unnecessary computational overhead.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary structured query generation step that translates natural language queries into efficient search queries. This intermediary layer acts as a bridge between the LLM's world knowledge and the media database, enabling the system to leverage LLM capabilities while avoiding direct computational burden on the LLM for routine retrieval operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If LLMs are used to directly identify media items from user queries, then the system can provide accurate results based on world knowledge, but the processing time increases due to multiple passes through the neural network

Engineering Contradiction:
Improveaccuracy of media item identificationVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary action by generating structured queries from natural language inputs before executing the actual media item retrieval. This preliminary structuring of the query allows subsequent database operations to be performed efficiently without requiring multiple passes through the neural network, thus reducing processing time while maintaining accuracy.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If the system uses only structured queries for media item identification, then computational efficiency improves, but the system loses the ability to effectively handle broad intent queries requiring world knowledge

Engineering Contradiction:
Improvecomputational efficiencyVSAvoidability to handle broad intent queries
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system dynamically selects the appropriate processing path based on the nature of the user query. For queries requiring world knowledge and broad interpretation, the LLM path is activated. For queries that can be directly translated into structured search operations, the structured query path is used. This dynamic adaptation allows the system to optimize computational efficiency while maintaining versatility.

Inventive Principle:
Principle #15Dynamics

AI summary

An electronic device associated with a media-providing service stores, in a vector space, a plurality of respective vector representations for respective media content items. The electronic device receives a user input, including a text string. The electronic device generates, using a neural network, a structured query based on the text string. The electronic device determines, based on the structured query, whether to generate a vector representation of a portion of the text string. When the electronic device determines to generate the vector representation of the portion of the text string, it generates the vector representation of the portion of the text string, wherein the vector representation is embedded in the vector space, and identifies a set of media items using the vector representation of the portion of the text string. And the electronic device provides one or more select media items from the set of media items to a user.
