Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display format of an e-book changes (e.g., text size, font size, line spacing), then the device can accommodate different user preferences and display requirements, but the user loses their reading position and may miss parts of the document
Solution Approach 1:
The system performs preliminary action by detecting format changes before the user can lose their reading position, and proactively displays a notification showing the difference between content before and after the change. This prevents the user from actually losing their place by alerting them to the change and showing them what content may have been affected.
Solution Approach 2:
The system implements feedback by displaying a notification that shows the user the difference between content displayed before and after the format change. This feedback mechanism informs the user about potential content loss or position changes, allowing them to understand what has changed and take appropriate action to locate their reading position.
2Ease of operation
If the display format changes, then the e-book can be optimized for different reading conditions and user needs, but the user must search for their reading position and missing content
Solution Approach 1:
The system performs preliminary action by detecting format changes before the user needs to search for their reading position. By proactively displaying a notification with the difference between content before and after the change, the system prepares the user in advance, eliminating the need for time-consuming searches.
Solution Approach 2:
The system provides immediate feedback about format changes and their impact on content display. This feedback includes showing the user the difference between content before and after the change, enabling them to quickly understand what content may have been affected and locate their reading position without extensive searching.
3Adaptability or versatility
If the display format is changed to accommodate user input, then the reading experience can be customized, but the user may miss parts of the displayed e-book
Solution Approach 1:
The system implements feedback by displaying a notification that shows the user the difference between content displayed before and after the format change. This feedback mechanism ensures content visibility by alerting the user to potential content loss and showing them exactly what content may have been affected by the customization, allowing them to review and locate any missed parts.
