Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If spring-dampened supporting rods are used for elastic installation, then vibration isolation is improved, but angular-displacement control deteriorates during severe impact
Solution Approach 1:
The supporting rod is segmented into multiple functional components: upper connecting plate, lower connecting plate, spring component, dampening component, and angular-displacement-limiting component. Each segment performs a specific function, allowing vibration isolation while controlling angular displacement during impact.
Solution Approach 2:
An angular-displacement-limiting component is introduced as an intermediary element between the spring-dampened supporting rod and the mounting bases. This intermediary mechanism prevents excessive angular displacement while maintaining the vibration isolation benefits of the spring-dampening system.
2Loss of time
If dampening force is increased to reduce reset time, then response speed is improved, but reset accuracy deteriorates
Solution Approach 1:
The dampening component uses non-linear dampening characteristics where the dampening coefficient changes with displacement and velocity. This allows strong dampening during impact (fast reset) while providing gentle dampening during the final settling phase (high accuracy).
Solution Approach 2:
The vibration isolation system combines spring elements (for elastic support) with dampening elements (for energy dissipation) in a composite structure. This composite approach enables simultaneous optimization of reset speed and reset accuracy by tuning the properties of each material component.
3Adaptability or versatility
If device center of gravity is eccentric on upper mounting surface, then adaptability is improved, but elastic property adjustment becomes difficult
Solution Approach 1:
Each supporting rod is equipped with independently adjustable spring components and dampening components, allowing local adjustment of elastic properties at each mounting point. This enables adaptation to eccentric center of gravity conditions while maintaining ease of adjustment through modular components.

Function Achieved in This Case
The platform ensures precise positioning accuracy and reliable operation of optoelectronic equipment by effectively isolating and damping severe impacts and vibrations, enhancing service life and reducing structural reinforcement needs, while also supporting the transition of optoelectronic devices from fixed land to various carriers.

Implementation Method 2
the supporting rod adopts a spring-dampened form
Implementation Method 3
Liquid dampening is superior to dry friction dampening. Since liquid dampening force is proportional to speed change; therefore, when the liquid dampening is adopted for the severe impact, the larger the transient speed change ΔV is, the larger the dampening force would be.
