Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed frame projection systems or LCD-based projectors are used, then dynamic content can be projected, but the device complexity and cost increase significantly
Solution Approach 1:
The patent uses a simplified projector that projects only essential information (copies of critical data) rather than attempting to replicate full LCD display functionality. This allows dynamic content to be conveyed through simplified visual cues without the complexity of conventional projection systems.
Solution Approach 2:
The invention employs inexpensive, simple projection components that can be easily replaced or updated, rather than investing in complex, expensive LCD-based projectors. This approach prioritizes cost-effectiveness and simplicity over high-fidelity dynamic display.
2Productivity
If conventional fixed frame projection systems are used, then projection stability is achieved, but the system cannot efficiently provide critical driver information in real-time
Solution Approach 1:
The system extracts only the most critical information elements needed for driver safety and presents them through simplified projection. By removing non-essential features from conventional projection systems, the patent achieves faster information delivery while maintaining sufficient stability for safety-critical notifications.
Solution Approach 2:
The projection system is designed to dynamically adjust its output based on real-time vehicle data and driver needs, rather than operating as a static fixed-frame system. This allows the projector to prioritize and adapt information delivery for maximum efficiency while maintaining adequate stability.
3Loss of information
If complex LCD-based projectors are used for dynamic content, then comprehensive information can be displayed, but the cost and manufacturing complexity increase
Solution Approach 1:
Rather than attempting to display all possible information with equal quality, the system focuses projection resources on delivering specific critical information with high clarity. This localized approach to information quality maintains manufacturing simplicity while ensuring essential data is communicated effectively.
Solution Approach 2:
The patent employs cost-effective projection components that can be manufactured simply and replaced if needed, rather than investing in expensive LCD-based projectors. This approach accepts that the projection system is a consumable component rather than a long-term capital investment.
