Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high accuracy mode is used to determine display position, then measurement precision is improved, but use of energy increases due to computational overhead
Solution Approach 1:
The system dynamically switches between first mode (low complexity) and second mode (high complexity) based on whether position update conditions are met. When conditions are met, it uses the simpler first mode to save energy; when conditions are not met, it switches to the more accurate second mode. This dynamic adaptation resolves the contradiction between measurement precision and energy consumption.
Solution Approach 2:
The system changes the computational complexity parameter based on position update conditions. By adjusting the mode of computation (first mode vs. second mode) according to whether sensing data variations exceed thresholds or time intervals are satisfied, it optimizes the balance between accuracy and power consumption.
2Use of energy by moving object
If low accuracy mode is used to determine display position, then use of energy is reduced, but measurement precision deteriorates
Solution Approach 1:
The system dynamically adjusts the computation mode based on real-time conditions. When position update conditions are satisfied (sensing data variation is small or time interval is short), it uses the energy-efficient first mode. When conditions are not satisfied, it switches to the accurate second mode, thus dynamically balancing energy consumption and measurement precision.
Solution Approach 2:
The computational parameter (mode of determination) is changed based on position update conditions. By switching between first mode (low complexity) and second mode (high complexity) according to sensing data variations and time intervals, the system optimizes the trade-off between power consumption and display position accuracy.
3Device complexity
If single mode is used to determine display position, then device complexity is reduced, but adaptability deteriorates due to inability to respond to user state changes
Solution Approach 1:
The system implements dynamic mode switching between first mode and second mode based on position update conditions derived from user state (sensing data variations and time intervals). This dynamic adaptation enables the system to respond to changing user states while maintaining manageable device complexity through a structured dual-mode architecture.
Solution Approach 2:
The system achieves multi-functionality by incorporating both first mode and second mode determination methods within a single display device. This allows the device to adapt to different user states and requirements, providing both energy-efficient operation and high-accuracy positioning when needed, thereby enhancing versatility without excessive complexity.
