Solution Overview

Problem

Mobile wireless communications devices face challenges in delivering targeted advertisements to users of unknown demographics, as they are used by a wide range of people, unlike traditional advertising venues which cater to specific demographics.

Innovation Solution

A communications system that includes an advertising server and mobile wireless communications devices equipped with processors, audio transducers, and wireless transceivers, which recognize keywords in voice communications to send targeted advertisements based on user interests, allowing for the presentation of ads during or after voice communications, and storing ad history to optimize ad delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If mobile wireless communications devices deliver advertisements to users of unknown demographics, then the device can reach a wide audience, but the advertisements cannot be effectively targeted to user interests

Engineering Contradiction:
Improveability to reach wide audienceVSAvoidlack of demographic information for targeting
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent introduces speech recognition technology as an intermediary that extracts meaningful information (keywords) from voice communications. This mediator bridges the gap between the device's lack of demographic knowledge and the need for targeted advertising by deriving user interests directly from spoken content during calls.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional demographic-based targeting mechanisms (which rely on user profiles, location data, or device characteristics) with a speech analysis-based system. Instead of using mechanical or statistical methods to infer user characteristics, the system directly analyzes voice communication content to determine advertising relevance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If keywords are recognized in real-time during voice communications to deliver targeted ads, then ad relevance to user interests is improved, but the system complexity increases

Engineering Contradiction:
Improvead relevance to user interestsVSAvoidsystem complexity for keyword recognition
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The mobile device performs speech recognition and keyword extraction independently during voice communications, without requiring external analysis systems. The device itself analyzes its own communication data to generate advertising targets, making the system self-sufficient and reducing overall system complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs speech recognition and keyword identification during the voice communication itself, before the advertising delivery phase. This preliminary analysis allows the system to prepare targeted advertisements in advance, smoothing the subsequent ad delivery process and reducing real-time complexity.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If advertisements are delivered during or after voice communications based on recognized keywords, then user engagement with ads is improved, but the risk of repetitive or unwanted ads increases

Engineering Contradiction:
Improveuser engagement with adsVSAvoidrepetitive or unwanted advertisements
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system uses recognized keywords from voice communications as feedback to dynamically select and deliver relevant advertisements. This feedback mechanism ensures that ads are based on actual user speech content rather than generic targeting, reducing repetitiveness while maintaining engagement through relevance.

Inventive Principle:
Principle #23Feedback
