Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the imaging module is used to capture signals from nucleic acid molecules, then detection capability is achieved, but the system becomes very sensitive to vibration causing image blur and sequencing inaccuracies
Solution Approach 1:
The system is divided into two separate modules: a vibration isolation module that handles external vibrations and a vibration damping module that handles internal vibrations. This segmentation allows each module to specialize in specific vibration frequencies and sources, improving overall vibration suppression effectiveness while maintaining detection precision.
Solution Approach 2:
A vibration isolation platform is introduced as an intermediary between the external environment and the imaging module. This platform acts as a mediator that captures and isolates external vibrations before they can affect the sensitive imaging components, thereby protecting the detection system while maintaining its sensitivity.
2Device complexity
If a single-layer structure is used for the vibration damping body, then device complexity is reduced, but vibration damping effectiveness is insufficient
Solution Approach 1:
The design transitions from a single-layer structure to a double-layer structure, adding a vertical dimension to the vibration damping approach. The first layer (vibration isolation platform) addresses external vibrations, while the second layer (vibration damping body with adjustable dampers) addresses internal vibrations, creating a multi-dimensional vibration suppression system that enhances reliability without excessive complexity.
3Ease of manufacture
If the natural frequency of the body is not adjusted relative to internal excitation frequency, then manufacturing is simpler, but internal vibration suppression is insufficient
Solution Approach 1:
The system incorporates adjustable vibration dampers that can modify the natural frequency of the vibration damping body. This parameter adjustment capability allows the system to optimize vibration suppression effectiveness by tuning the natural frequency away from internal excitation frequencies, while the adjustable design maintains reasonable manufacturing complexity through modular components.
