Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mechanical vibration poses a significant challenge in detection systems and sequencing systems, particularly affecting imaging modules that are sensitive to external and internal vibrations, leading to inaccurate and unreliable sequencing results.
Innovation Solution
A vibration damping structure with a double-layer body design, comprising an upper and lower structure connected by an intermediate structure, with a natural frequency greater than or equal to √{square root over (2)} times the internal excitation frequency, effectively suppresses vibrations in both two-dimensional and three-dimensional movements.
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 improved, but sensitivity to vibration increases leading to inaccurate sequencing results
Solution Approach 1:
The body is divided into an upper structure and a lower structure as separate segments, connected through intermediate structures. This segmentation allows independent vibration control of each segment, enabling the upper structure to be isolated from vibrations generated by the lower structure's movement, thereby improving sequencing accuracy while maintaining detection capability
Solution Approach 2:
Intermediate structures serve as mediators between the upper and lower structures. These intermediates include vibration damping components that filter and reduce vibration transmission, allowing the imaging module on the upper structure to capture clear images of nucleic acid molecules without interference from vibrations generated by the lower structure's two-dimensional movement
2Device complexity
If a single-layer body structure is used, then device complexity is reduced, but vibration damping effect is insufficient
Solution Approach 1:
The design transitions from a single-layer structure to a double-layer structure with upper and lower bodies separated in the vertical dimension. This dimensional change creates space for intermediate vibration damping structures, enabling effective vibration isolation while maintaining relatively simple overall device architecture
Solution Approach 2:
The vibration damping structure employs composite construction with upper and lower structural layers connected by intermediate damping elements. This composite approach combines rigid structural components with vibration-absorbing materials, achieving effective vibration damping without significantly increasing device 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 natural frequency requires structural modification
Solution Approach 1:
The design changes the natural frequency parameter of the body by modifying the structural configuration to a double-layer system with intermediate damping elements. This parameter change ensures the natural frequency is greater than or equal to √2 times the internal excitation frequency, avoiding resonance and reducing vibration amplification while maintaining structural feasibility
