Solution Overview

Problem

Existing browser extensions lack the ability to flag specified words or phrases typed into a web browser, leading to potential misuse or inappropriate content creation.

Innovation Solution

A browser extension recognition system that flags specified words or phrases by displaying a warning dialog when they are typed, allowing users to manage a list of blocked words, import/export lists, and switch the system between active and inactive states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If browser extensions are installed to add new features, then browser functionality is extended, but browser security and content control are compromised

Engineering Contradiction:
Improvebrowser functionalityVSAvoidcontent control
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary component - a browser extension that acts as a mediator between the user and the browser content. This extension monitors and controls what content can be displayed or interacted with by comparing it against a blocklist, thereby maintaining both extended functionality and improved content control through the intermediary mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system applies preliminary anti-action by pre-populating a blocklist with harmful or unwanted content identifiers before the browser encounters such content. The extension proactively prevents problematic content from being displayed or interacted with by checking against this pre-established blocklist, rather than reacting after the harm occurs.

Inventive Principle:
Principle #9Preliminary anti-action

2Object-affected harmful factors

If a blocklist of words is implemented to prevent typing, then content safety is improved, but user convenience deteriorates

Engineering Contradiction:
Improvecontent safetyVSAvoidtyping convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system applies partial action by blocking only specific words or patterns that match the blocklist criteria, rather than preventing all typing input. This selective approach maintains content safety for harmful terms while preserving user convenience for normal typing activities, avoiding excessive restriction.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The extension implements feedback by providing visual indicators or notifications when a blocked word is detected, allowing users to understand why their input was restricted. This feedback mechanism helps users learn from the blocks and adjust their typing accordingly, maintaining ease of operation while enforcing content safety rules.

Inventive Principle:
Principle #23Feedback

AI summary

A browser extension recognition system and methods are provided for flagging specified words when they are typed into a web-browser application. A warning dialog box is displayed when a typed word or phrase is determined to match a word or phrase in a saved list of the words to be blocked. The warning dialog box indicates that the word or phrase matches a blocked word or phrase and prompts an end-user to continue or stop typing the block word or phrase. Settings are configured to enable the end-user to add new words and phrases to the list of words and remove existing words and phrases from the list of words. A desired group of words and/or phrases to be blocked can be imported from an external file, and an external file containing a listing of all the words and phrases comprising the list of words can be exported.
