Solution Overview
Problem
Conventional optical systems face challenges in achieving high throughput of focused images due to movement of components, leading to blurred images during rapid capture of different regions in biological or chemical analysis systems.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the optical system components are moved to capture images of different regions rapidly, then the productivity is improved, but the manufacturing precision deteriorates due to blurred images from vibration
Solution Approach 1:
The vibration capture assembly dynamically transitions between damping mode and isolation mode based on the operational state of the actuation assembly. During rapid movement phases, the system engages damping to resist vibration; during stationary capture phases, it switches to isolation mode to prevent vibration transmission, thereby maintaining image precision across different productivity levels
Solution Approach 2:
The system changes the physical state of the vibration capture assembly by altering the electrical resistance of the coil through selective voltage application. This parameter change enables the coil to generate or dissipate electromagnetic forces that counteract or allow vibration, dynamically adjusting the system's vibration characteristics to match operational requirements
2Productivity
If the actuation assembly moves the imaging assembly rapidly to capture different regions, then the productivity is improved, but the stability of the object's composition deteriorates due to frame vibration
Solution Approach 1:
The vibration capture assembly applies preliminary counteracting forces through electromagnetic damping during actuation phases. By generating electromagnetic forces that oppose the direction of vibration before it can significantly affect the frame, the system prevents instability while maintaining rapid movement capability for high productivity
3Stability of the object's composition
If the vibration capture assembly resists frame movement during actuation, then the stability is improved, but the energy consumption increases
Solution Approach 1:
The system applies voltage to the coil selectively during specific phases of operation - primarily during actuation when vibration occurs - rather than continuously. This periodic application of electromagnetic damping provides stability when needed while minimizing energy consumption during stationary image capture phases
Solution Approach 2:
The controller dynamically adjusts the electrical resistance of the coil by applying or removing voltage based on operational requirements. This parameter change allows the system to optimize between stability (when voltage is applied) and energy efficiency (when voltage is removed), matching energy consumption to actual stabilization needs
