Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If existing eco modes are activated to save battery power, then battery consumption is reduced, but user experience is significantly degraded due to uniform reduction of CPU/GPU performance and electrochromic features
Solution Approach 1:
The patent applies local quality by selectively managing power consumption of specific electrochromic features (such as automatic tint adjustment, color changing, and transition speed) rather than uniformly degrading all device functionalities. The system identifies and optimizes power consumption at the feature level, allowing users to maintain acceptable performance of critical functions while reducing power usage of less essential electrochromic features.
Solution Approach 2:
The system dynamically adjusts electrochromic feature parameters based on real-time battery state and usage patterns. Instead of static eco mode settings, the system continuously monitors battery charge levels, usage frequency, and user preferences to adaptively control feature activation and performance, enabling flexible power management that responds to changing conditions.
2Use of energy by moving object
If generic eco modes are applied to all smart devices, then battery power is saved, but the solution is inefficient for electrochromic eyewear where electrochromic features consume approximately 90% of total power
Solution Approach 1:
The patent segments the power management approach by specifically targeting electrochromic feature power consumption rather than applying generic device-wide eco modes. The system divides power management into distinct controllable features (automatic tint adjustment, manual color changing, transition speed control) and optimizes each independently, recognizing that electrochromic features consume approximately 90% of total power in EC eyewear devices.
Solution Approach 2:
The system changes operational parameters of electrochromic features based on battery state and usage analysis. This includes adjusting transition speeds, limiting color palette options, reducing frequency of automatic adjustments, and modifying activation thresholds for electrochromic functions, thereby directly addressing the primary power consumption source in EC eyewear.
3Use of energy by moving object
If existing eco modes are used, then battery saving is achieved in emergency situations, but the generic degradation approach is not suitable for long-term optimized efficiency
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring battery charge levels, usage patterns, and feature performance. This feedback loop enables the system to learn from user behavior and adjust electrochromic feature management strategies over time, optimizing battery autonomy for long-term use rather than just providing emergency battery saving measures.
Solution Approach 2:
The system performs preliminary analysis of usage patterns and user preferences to proactively configure optimal power management strategies before battery depletion occurs. By pre-configuring feature settings based on learned usage patterns, the system prepares efficient power consumption profiles that extend battery autonomy without requiring users to reactively activate emergency eco modes.
