Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If generative AI is used to phase-classify search queries and generate description content, then analysis accuracy of user behavior is improved, but processing time and computational resources increase

Engineering Contradiction:
Improveanalysis accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary phase classification of search queries using generative AI before detailed analysis. By pre-categorizing queries into phases (awareness, consideration, decision), the system prepares structured data in advance that accelerates subsequent marketing analysis and reduces real-time processing requirements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments search queries into multiple distinct phases (awareness, consideration, decision) based on user intent. This segmentation allows the system to apply different analysis methods to each phase, improving overall analysis accuracy while enabling parallel processing that reduces total processing time.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If search queries are classified into multiple phases with detailed description content, then understanding of user intent is improved, but system complexity increases

Engineering Contradiction:
Improveunderstanding of user intentVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary classification layer that translates complex search query data into standardized phase categories (awareness, consideration, decision). This intermediary structure simplifies the representation of user intent while preserving essential information, making the data more manageable for marketing analysis without losing critical insights.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system transforms search query characteristics into phase classification parameters. By changing the parameter representation from raw query text to structured phase labels with description content, the system maintains comprehensive understanding of user intent while reducing data complexity for subsequent processing and analysis.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If phase classification and description generation are performed for all search queries, then marketing analysis effectiveness is improved, but processing cost increases

Engineering Contradiction:
Improvemarketing analysis effectivenessVSAvoidprocessing cost
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent applies phase classification and description generation selectively to search queries that meet specific criteria rather than processing all queries uniformly. By focusing computational resources on high-value queries (e.g., those indicating strong purchase intent or unique user behaviors), the system achieves effective marketing analysis while reducing overall processing costs and energy consumption.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An information processing apparatus according to the present application includes a specifying unit, a processing unit, and a provision unit. The specifying unit specifies search queries of a plurality of users using a predetermined query for a search. The processing unit causes generative AI to classify the search queries into a plurality of phases and to generate description content describing the phase for each of the phases by inputting information regarding the search queries specified by the specifying unit to the generative AI. The provision unit provides information for displaying information indicating the plurality of phases classified by the generative AI together with the description content generated by the generative AI.
