Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal management efforts are implemented to manage solar loading heat loads, then the electronic display is protected from damage, but additional power is consumed
Solution Approach 1:
The system performs preliminary detection of solar loading conditions using sensors before thermal damage occurs. The controller proactively adjusts thermal management operations based on detected solar angles and intensity, preventing damage before it happens rather than reacting after overheating occurs.
Solution Approach 2:
The system continuously monitors thermal conditions and solar loading using sensors, then feeds this information back to the controller which adjusts thermal management operations in real-time. This closed-loop feedback system optimizes power consumption by activating cooling only when and where thermal management is actually needed based on detected conditions.
2Illumination intensity
If electronic display brightness is adjusted to make images visible under solar loading, then image quality is maintained, but additional power is consumed
Solution Approach 1:
The system uses sensors to detect ambient light conditions and solar loading, then feeds this information back to the controller which dynamically adjusts display brightness. This feedback mechanism ensures images remain visible under varying solar conditions while minimizing power consumption by adjusting brightness only to the extent necessary for visibility.
Solution Approach 2:
The system changes the brightness parameter of the electronic display based on detected solar loading conditions and ambient light levels. By dynamically adjusting this parameter in response to environmental conditions, the system maintains image visibility while optimizing power consumption rather than operating at fixed high brightness.
3Use of energy by stationary object
If orientation detection devices and sensors are added to control operations based on solar angle, then thermal management and brightness are optimized, but device complexity increases
Solution Approach 1:
The controller is designed to perform multiple functions: it processes data from orientation detection devices, analyzes sensor information about thermal and light conditions, determines solar angles, and controls both thermal management and brightness operations. This multi-functional controller reduces overall system complexity by consolidating control logic rather than requiring separate dedicated components for each function.
Solution Approach 2:
The system merges orientation detection, environmental sensing, solar angle calculation, and control operations into an integrated system managed by a single controller. By combining these functions into one coordinated system rather than separate independent components, the patent reduces overall device complexity while achieving optimized thermal and brightness management.
