Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Mobile communication devices struggle to receive and store tracking cookies, which are essential for websites to offer full functionality, as they do not receive and store cookies as readily as personal computers.

Innovation Solution

Encoding specific pixels with numeric values in the Red Green and Blue (RGB) color code within website content transmitted to a network access device, allowing for unique identification of the user without relying on cookies, enabling customized web page content delivery based on user profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If tracking cookies are used to identify users and provide personalized content, then user personalization and website functionality are improved, but mobile devices cannot reliably store and transmit cookies, causing tracking failures

Engineering Contradiction:

Improveuser personalizationVSAvoidcookie storage and transmission

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts the tracking functionality from the cookie-based system and implements it through alternative methods: device fingerprinting (analyzing device characteristics), localStorage/IndexedDB storage (alternative client-side storage), and server-side session management. This removes the dependency on cookies while maintaining the core personalization capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a universal tracking system that works across multiple device types (mobile, desktop, tablet) by implementing multiple identification mechanisms simultaneously: device fingerprints, stored tokens, and session identifiers. This multi-functional approach ensures reliable user identification regardless of device capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If cookies are used to track browsing history and user behavior, then content personalization is improved, but user privacy and data security are compromised

Engineering Contradiction:

Improvecontent personalizationVSAvoiduser privacy exposure

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements local quality by processing and storing user data locally on the user's device using localStorage and IndexedDB, rather than relying on server-side cookies. This allows personalization to be maintained while giving users greater control over their data and reducing privacy exposure to external servers.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces an intermediary layer between user behavior tracking and server communication. Device fingerprints and locally stored tokens act as intermediaries that enable personalized content delivery without directly exposing detailed user browsing history to servers, thereby protecting user privacy while maintaining personalization functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)
