Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the control unit provides detailed and varied information display, then user understanding and utilization of features improves, but device complexity increases
Solution Approach 1:
The display is segmented into multiple loci with different data formats (fixed segment and dot matrix). Each locus presents specific information types in optimized formats, allowing detailed information display while organizing complexity into manageable segments that are easier to process and display.
Solution Approach 2:
The patent adds a temporal dimension to information display through parameter toggling capability. Users can switch between different parameter views (e.g., temperature, humidity, air quality) over time, enabling comprehensive information presentation without requiring all parameters to be displayed simultaneously, thus managing display complexity.
2Ease of operation
If the control unit offers flexible programming and display capabilities, then ease of operation improves, but device complexity increases
Solution Approach 1:
The control unit implements dynamic programming capabilities where parameters can be toggled and reconfigured based on user needs. The display adapts dynamically between different data formats and parameter sets, providing flexibility without requiring users to navigate complex static programming structures.
Solution Approach 2:
The control unit integrates multiple functions into a single device including environmental monitoring, scheduling, reminders, and customizable display options. By consolidating these diverse functions into one universal interface with standardized interaction patterns, the system achieves programming flexibility without proportionally increasing operational complexity.
3Loss of information
If the display presents multiple parameters simultaneously, then information completeness improves, but ease of operation deteriorates due to user confusion
Solution Approach 1:
Multiple parameters are segmented across different display loci with specialized formats. Critical parameters like temperature use fixed segment displays for immediate readability, while secondary parameters use dot matrix displays. This segmentation allows comprehensive information presentation while organizing data to reduce cognitive load and user confusion.
Solution Approach 2:
Different regions of the display (loci) are optimized for different parameter types with appropriate data formats. This local quality optimization ensures that each parameter is presented in the most suitable format for its nature, improving overall information completeness while maintaining ease of operation through format-appropriate presentation.
