Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mechanical vibration poses a significant challenge in sequencing systems, particularly affecting the imaging module's ability to capture clear images of nucleic acid molecules, leading to inaccurate sequencing results due to external and internal excitation.
Innovation Solution
A vibration damping structure with a double-layer body design, comprising an upper structure, lower structure, and intermediate structure, with a natural frequency greater than twice the internal excitation frequency, effectively suppresses vibrations through a double-layer structure and support system, including vibration-proof gel pads and supporting legs, to isolate and attenuate external and internal vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the imaging module is used to capture signals from nucleic acid molecules, then sequencing detection capability is achieved, but the system becomes highly sensitive to vibration causing image blur and reduced accuracy
Solution Approach 1:
The body is divided into an upper structure and a lower structure separated by an intermediate structure, creating a segmented dual-layer configuration. This segmentation isolates the imaging module (mounted on the upper structure) from vibrations generated by the lower structure, reducing vibration sensitivity while maintaining sequencing detection capability
Solution Approach 2:
The intermediate structure acts as a mediator between the upper and lower structures. It transmits necessary mechanical support while filtering and attenuating vibration transmission, serving as an isolation layer that protects the imaging module from harmful vibrations generated by the lower structure
2Device complexity
If a single-layer body structure is used, then device complexity is reduced, but vibration damping effectiveness is insufficient
Solution Approach 1:
The design transitions from a single-layer to a dual-layer body structure, adding a vertical dimension to vibration isolation. The upper and lower structures are separated by the intermediate structure, creating multiple vibration isolation pathways and enhancing damping effectiveness without excessive complexity
3Stability of the object's composition
If the natural frequency of the body is close to the internal excitation frequency, then resonance occurs amplifying vibration, but increasing the natural frequency requires structural modification
Solution Approach 1:
The natural frequency of the body is adjusted to be greater than or equal to twice the internal excitation frequency, changing the frequency parameter to avoid resonance. This is achieved through the dual-layer structure design with the intermediate structure, which modifies the overall stiffness and mass distribution to achieve the desired frequency relationship
