Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed excitation waveform is used for all cameras, then the measurement process is simple, but the shake evaluation accuracy deteriorates due to variations in camera specifications
Solution Approach 1:
The excitation waveform is made dynamic and adaptable to different camera specifications. The system automatically adjusts waveform parameters such as frequency, amplitude, and duration based on the specific camera being tested, transforming a static measurement process into a dynamic one that optimizes for each device
Solution Approach 2:
The system changes key parameters of the excitation waveform (frequency, amplitude, duration) based on camera specifications like weight and sensor type. This allows the same excitation apparatus to optimize its output for different camera models, improving measurement accuracy without requiring different hardware for each camera type
2Measurement precision
If the excitation waveform is adjusted for each camera specification, then the shake evaluation accuracy is improved, but the measurement process time increases
Solution Approach 1:
The system performs preliminary adjustments by pre-calculating optimal waveform parameters based on camera specifications before the actual shake measurement begins. This preparation phase allows the measurement itself to proceed efficiently without real-time computation delays
Solution Approach 2:
The system replaces manual waveform adjustment with automated computational algorithms that quickly determine optimal parameters based on camera specs. This substitution of automated processing for manual tuning significantly reduces the time required while maintaining high measurement accuracy
3Adaptability or versatility
If a standard excitation waveform is used, then the device complexity is low, but the adaptability to different camera types deteriorates
Solution Approach 1:
The excitation waveform generation system is designed to be universal, capable of adapting to multiple camera types and specifications through software configuration rather than hardware changes. This allows a single apparatus to serve multiple functions across different camera models
Solution Approach 2:
The system introduces an intermediary software layer that translates camera specifications into optimized waveform parameters. This intermediary component bridges the gap between the fixed excitation apparatus and variable camera characteristics, enabling adaptability without modifying the core hardware
