Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If software is installed to detect network errors, then network error detection capability is improved, but computer security deteriorates due to potential software loopholes and hacker attacks
Solution Approach 1:
The patent implements network error detection using the browser's built-in capabilities and native JavaScript code, eliminating the need for external detection software. The browser itself performs the detection function through integrated error detection mechanisms, ensuring security while maintaining detection capability
Solution Approach 2:
The patent extracts the network error detection function from separate external software and integrates it directly into the browser's core functionality. By removing the need for standalone detection applications, the system eliminates their associated security vulnerabilities while preserving error detection capabilities
2Difficulty of detecting and measuring
If external software is used for network error detection, then detection functionality is improved, but system complexity increases due to additional software installation and configuration
Solution Approach 1:
The patent merges the network error detection functionality with the browser's existing error handling mechanisms. By combining these functions into a unified system, the patent eliminates the need for separate detection software and its associated installation and configuration complexity
Solution Approach 2:
The patent makes the browser multi-functional by enabling it to perform both web browsing and network error detection. The browser's native capabilities are extended to include comprehensive error detection, eliminating the need for specialized detection tools and reducing overall system complexity

AI summary
A network error detecting method checks if a network connection device has an Internet protocol (IP) address, if domain name mapping of web pages is correct, and if data communication between a web browser and a web server is correct. Accordingly, the network connection device informs the web browser of an IP address error, a domain name mapping error, or a data communication error. The web browser displays the network errors to users when the network errors are detected.
