Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the battery capacity is increased to improve endurance, then the device can operate longer without charging, but the device size and weight increase
Solution Approach 1:
The patent implements dynamic energy management by continuously monitoring energy availability levels and adjusting device operations in real-time. The system transitions between different operational states (normal operation, energy conservation mode, charging mode) based on current energy conditions, allowing the device to achieve extended endurance without requiring a permanently larger battery capacity.
Solution Approach 2:
The system performs preliminary assessment of energy availability by detecting charging resources and predicting future energy states before critical battery depletion occurs. This allows the device to proactively adjust operations, navigate to charging locations, or alert users in advance, preventing emergency situations and optimizing battery utilization without needing excessive capacity margins.
2Ease of operation
If the device operates continuously with high power consumption functions, then user experience is improved, but battery endurance decreases
Solution Approach 1:
The patent dynamically adjusts device operations based on energy availability levels. When energy availability is high (charging available), the system enables high-power functions and rich features. When energy availability is low (no charging available), the system automatically activates energy conservation modes, limiting non-essential functions while maintaining core operations, thus balancing user experience with battery endurance.
Solution Approach 2:
The system changes operational parameters such as screen brightness, processor frequency, network data transmission rates, and sensor activation based on energy availability. These parameter adjustments allow the device to optimize performance within available energy constraints, maintaining acceptable user experience across different battery states without requiring a larger battery.
3Adaptability or versatility
If charging resources are made more widely available, then battery endurance problem is resolved, but infrastructure complexity and cost increase
Solution Approach 1:
The patent enables devices to utilize multiple types of charging resources through a unified energy management framework. The system can detect and adapt to various charging infrastructures (wireless charging pads, charging piles, power banks, other devices as power sources) and automatically selects appropriate charging methods, making the device adaptable to diverse charging environments without requiring dedicated hardware for each charging type.
Solution Approach 2:
The system performs self-assessment of energy availability by autonomously detecting charging resources in the environment, evaluating their accessibility, and determining optimal charging strategies without requiring complex external coordination. The device independently navigates to charging locations, initiates charging protocols, and manages power intake, reducing the burden on charging infrastructure complexity.
