Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional systems are used for advertisement delivery, then user behavior tracking is implemented, but keyword extraction and contextual advertisement generation are ineffective

Engineering Contradiction:

Improvekeyword extraction accuracyVSAvoidadvertisement generation effectiveness

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent introduces a keyword extraction engine as an intermediary component between web page content and advertisement generation systems. This engine automatically extracts relevant keywords from web pages and uses them to generate contextual advertisements, bridging the gap between content analysis and ad delivery without manual intervention.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual or rule-based keyword extraction methods with an automated keyword extraction engine that uses computational algorithms to identify and extract relevant keywords from web page content, substituting mechanical manual processes with automated computational systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If merchants implement their own transaction tracking and rewarding systems, then purchase transactions can be monitored, but administrative burden increases significantly

Engineering Contradiction:

Improvetransaction tracking accuracyVSAvoidsystem administrative complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the transaction tracking and rewarding functionality from the merchant's core system and places it in a separate affiliate program management system. This extraction allows merchants to monitor transactions without implementing complex tracking infrastructure themselves, reducing their administrative burden while maintaining reliable tracking.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an affiliate program management system as an intermediary that handles transaction tracking and reward distribution. This intermediary layer processes transaction data and manages affiliate rewards without requiring merchants to build their own tracking infrastructure, simplifying the merchant's system while maintaining accurate tracking.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If affiliate programs are implemented for transaction tracking, then purchase transactions can be rewarded, but fraudulent transactions risk increases

Engineering Contradiction:

Improvetransaction processing efficiencyVSAvoidtransaction fraud prevention

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where the affiliate program management system continuously monitors transaction patterns, validates transaction authenticity, and adjusts reward distributions based on verified legitimate transactions. This feedback loop helps identify and prevent fraudulent transactions while maintaining efficient processing of legitimate ones.

Inventive Principle:

Principle #23Feedback

4Measurement precision

If manual keyword extraction methods are used, then web page content can be analyzed, but time efficiency decreases

Engineering Contradiction:

Improvecontent analysis accuracyVSAvoidkeyword extraction time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual keyword extraction with an automated keyword extraction engine that uses computational algorithms to rapidly analyze web page content and identify relevant keywords, substituting time-consuming manual processes with efficient automated computational systems while maintaining or improving extraction accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A computer-implemented system and method for keyword extraction and contextual advertisement generation are disclosed. The system in an example embodiment includes a keyword extraction service to receive from a consumer application a request for activation of a keyword extraction service via an application programming interface, the request including an identity of a content source, the request further including an identification of a particular extraction process to be used by the keyword extraction service on the identified content source; determine if the keyword extraction service has already processed the identified content source and retained extracted keywords in a data store; extract keywords from the identified content source using the particular extraction process identified in the request; and make the extracted keywords accessible to the consumer application.
