Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually check manuals or execute specific applications to solve errors, then they can obtain error solutions, but the time required to resolve errors increases and user convenience deteriorates
Solution Approach 1:
The mobile terminal automatically detects errors through screen information monitoring and autonomously searches for and displays guide information without requiring users to manually execute applications or check manuals. The system serves itself by automatically identifying error states and providing corresponding solutions, eliminating the need for user intervention in the error resolution process.
Solution Approach 2:
The system pre-prepares guide information for various error conditions and makes it readily available. When an error occurs, the corresponding guide information is already prepared and can be immediately displayed, eliminating the time delay associated with manual search processes. The error detection mechanism continuously monitors screen information to identify errors at their earliest occurrence.
2Ease of operation
If detailed manuals are provided for each function, then users can correctly use functions, but the device complexity and information volume increase
Solution Approach 1:
The system extracts only the necessary guide information related to the specific error that has occurred, rather than requiring users to navigate through comprehensive manuals containing all possible function descriptions. By monitoring screen information and identifying specific error states, the system selectively retrieves and displays only the relevant troubleshooting steps, filtering out unnecessary information.
Solution Approach 2:
Instead of providing uniform comprehensive manuals for all functions, the system provides localized, context-specific guide information tailored to the actual error state detected. Each error condition receives customized guidance based on the specific screen information analyzed, ensuring that users receive precisely the information needed for their current problem rather than generic manual content.
3Measurement precision
If the system monitors screen information changes to detect errors, then error detection accuracy improves, but the processing load and system complexity increase
Solution Approach 1:
The controller continuously monitors screen information output and uses this feedback to detect error states. By establishing a closed-loop monitoring system that tracks changes in screen information and compares them against known error patterns, the system achieves accurate error detection. The feedback mechanism allows the system to adaptively identify errors based on actual runtime behavior rather than relying on pre-defined error conditions.
