Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional fixed acquisition methods are used, then system simplicity is maintained, but measurement precision and adaptability deteriorate due to inability to compensate for environmental variations
Solution Approach 1:
The patent implements dynamic switching between temporal and angular acquisition schemes based on real-time environmental conditions. The system transitions from static fixed acquisition methods to dynamic adaptive methods, where the acquisition strategy is adjusted during operation to maintain measurement precision despite environmental variations such as temperature fluctuations and successive accelerations.
Solution Approach 2:
The system changes acquisition parameters dynamically by switching between two distinct acquisition schemes: temporal acquisition (acquiring measurements at regular time intervals) and angular acquisition (acquiring measurements at regular angular intervals of the beam scanner). This parameter change allows the system to adapt to different environmental conditions and maintain measurement accuracy without requiring complex hardware modifications.
2Measurement precision
If temporal acquisition scheme is used, then acquisition speed is maintained, but measurement precision deteriorates under environmental variations
Solution Approach 1:
The patent makes the acquisition system universal by implementing multi-functionality that allows switching between temporal and angular acquisition schemes. The same acquisition engine can operate in multiple modes depending on environmental conditions, making the system adaptable to various scenarios while maintaining measurement precision. This multi-functionality resolves the contradiction by enabling the system to select the appropriate acquisition mode for each specific situation.
3Productivity
If fixed acquisition instructions are executed, then processing simplicity is maintained, but productivity and adaptability deteriorate due to inability to respond to real-time conditions
Solution Approach 1:
The system prepares both temporal and angular acquisition instruction sets in advance, but only executes the relevant one based on real-time environmental assessment. This preliminary preparation of multiple instruction sets allows the system to quickly switch between acquisition modes without complex real-time processing decisions, maintaining processing efficiency while enabling adaptive response to changing conditions.
