Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple scanning imaging systems are used to achieve 360° scanning coverage, then the scanning coverage and capability are improved, but the time synchronization accuracy between systems deteriorates due to independent scanning processes
Solution Approach 1:
The patent introduces a beam synchronization pulse signal as an intermediary to synchronize multiple scanning imaging systems. This external synchronization signal serves as a common reference that coordinates the independent scanning processes, allowing systems to maintain accurate time synchronization while operating independently to achieve comprehensive scanning coverage.
2Ease of operation
If independent scanning processes are used for each imaging system, then the operational independence and flexibility are improved, but the data accuracy deteriorates due to time synchronization delays
Solution Approach 1:
The patent implements a feedback mechanism where each scanning imaging system monitors the beam synchronization pulse signal and adjusts its detection data acquisition timing accordingly. This feedback loop ensures that while systems operate independently, they continuously align their operations to maintain accurate time synchronization and data accuracy.
Solution Approach 2:
The beam synchronization pulse signal acts as an intermediary that coordinates between independent scanning processes. It provides a common temporal reference that allows each system to maintain operational independence while ensuring synchronized data acquisition for accurate results.
3Productivity
If multiple scanning imaging systems operate simultaneously, then the scanning efficiency and productivity are improved, but the complexity of time synchronization increases
Solution Approach 1:
The beam synchronization pulse signal serves as a simple intermediary mechanism that coordinates multiple scanning imaging systems. This approach maintains high scanning efficiency by allowing simultaneous operation while avoiding complex synchronization protocols, as the shared pulse signal provides straightforward timing references for all systems.
