Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If visual displays are integrated into mobile computing devices, then display quality and size can be improved, but power consumption and cost increase significantly
Solution Approach 1:
The system divides the mobile computing device into two separate components: a portable computing device containing processing and storage components, and a visual display device. These segments communicate via wireless connection, allowing the display to be large and high-quality while the computing device remains small and low-power.
Solution Approach 2:
The visual display is extracted from the portable computing device entirely. The display hardware, power source, and processing components are separated into independent devices, eliminating the need for the computing device to house power-hungry display components.
2Adaptability or versatility
If visual displays are integrated into mobile computing devices, then display functionality is improved, but device cost increases
Solution Approach 1:
The portable computing device is designed to work with multiple different visual display devices through wireless communication. A single computing device can interface with various displays including projectors, televisions, and monitors, eliminating the need to manufacture different display hardware for each computing device variant.
Solution Approach 2:
Instead of embedding expensive display hardware in each computing device, the system uses wireless transmission to copy visual output to external displays. The computing device transmits digital signals that are rendered by the external display hardware, avoiding duplication of expensive display components.
3Use of energy by moving object
If computing and storage components are separated from visual displays, then power consumption is reduced, but device complexity increases
Solution Approach 1:
A wireless communication interface acts as an intermediary between the portable computing device and visual display device. This standardized communication layer simplifies the interaction between separate components, handling data transmission and synchronization without requiring complex integration hardware.
Solution Approach 2:
Physical connections and integrated circuits are replaced with wireless electromagnetic communication. The mechanical and electrical integration of display components is substituted by radio frequency or optical wireless links, reducing hardware complexity while maintaining functionality.
4Adaptability or versatility
If separate power sources are used for computing and display components, then operational flexibility is improved, but charging requirements increase
Solution Approach 1:
The system dynamically adapts to different power availability scenarios. The portable computing device and visual display device can operate independently with their own power sources, and the system can switch between different operational modes depending on which device has power available, optimizing flexibility while managing charging needs.
