Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The challenge lies in delivering large format rich advertising content efficiently over wireless networks to mobile devices while respecting limited data throughput and power constraints, and ensuring convenient deployment, targeting, and measurement of advertising presentations.

Innovation Solution

The solution involves leveraging a multicast network for cost-efficient delivery of advertising content, using a client ad syndication interface that selects and renders advertisements based on filtering constraints, allowing for local caching and reporting usage metrics, thereby reducing the burden on mobile devices and networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If large format rich advertising content is pushed to mobile devices, then advertising quality and user experience are improved, but wireless network throughput and mobile device power are exceeded

Engineering Contradiction:

Improveadvertising content qualityVSAvoidmobile device power consumption

Core Design Contradiction:

Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The patent segments advertising content into multiple smaller packets that are transmitted separately over time. Instead of pushing a complete large-format ad in one go, the system divides the content into manageable segments that can be received and cached incrementally, reducing peak bandwidth requirements and power consumption while maintaining ad quality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by pre-fetching and caching advertising content on mobile devices before it is actually needed for display. The system proactively downloads ad content during periods of lower network usage or when the device is charging, so that when an ad opportunity arises, the content is already available locally, eliminating the need for high-throughput real-time transmission.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If advertising content is delivered individually to each mobile device, then targeted advertising is achieved, but network costs and complexity increase

Engineering Contradiction:

Improveadvertising targeting capabilityVSAvoidnetwork delivery complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges individual device-specific ad deliveries into a single multicast transmission. By identifying common advertising content that can be delivered to multiple devices simultaneously, the system consolidates what would otherwise be numerous separate unicast transmissions into one efficient multicast stream, reducing network complexity and costs while maintaining the ability to target specific device groups.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements universality by creating a multi-functional advertising delivery system that can operate in both unicast and multicast modes. The system universally handles different delivery scenarios - using multicast for broad distribution of common ad content and unicast for device-specific targeted ads - thereby achieving adaptability across different advertising requirements while optimizing network efficiency.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Speed

If advertising content is cached locally on mobile devices, then delivery speed is improved, but device storage and data management complexity increase

Engineering Contradiction:

Improveadvertising content delivery speedVSAvoidlocal cache management complexity

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary advertising management system that mediates between the network and mobile device caches. This intermediary layer handles the complexity of cache management, including tracking what ads are cached on which devices, determining what needs to be updated or removed, and coordinating with both the content delivery network and device storage. This allows fast local delivery while centralizing the management complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Measurement precision

If filtering constraints are applied to advertising content requests, then ad relevance is improved, but processing time and computational resources increase

Engineering Contradiction:

Improveadvertising relevance accuracyVSAvoidcontent selection processing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-filtering and pre-processing advertising content based on device profiles, user preferences, and contextual information before the content is cached or requested. Filtering constraints are evaluated in advance during content creation and initial caching, so that when an ad opportunity arises, the selection process is dramatically accelerated because much of the filtering work has already been completed.

Inventive Principle:

Principle #10Preliminary action

AI summary

Apparatus and methods for distributing advertising content to a mobile device. An application is executed on a mobile device containing an advertising opportunity. Advertising content is requested from an advertisement syndication interface. A filtering constraint applicable to the advertising content request is identified and used to select and advertisement from a local advertising cache. The selected advertisement is rendered in a composite with rendering of content of the application.
