Linear Vibration Conveyor Rotatable Spring Articulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear vibration conveyors experience adverse vibration transmission between the counterweight and foundation, leading to disruptions during operation and sorting of goods, and can also affect the environment with unwanted vibrations.
Innovation Solution
The use of rotatably articulated free spring sections at the ends of the second group of springs creates a pivot point, decoupling vibrations and allowing for flexible deformation, thereby reducing vibration transmission between the counterweight and foundation, and employing cylinder compression springs for enhanced vibration decoupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the counterweight is rigidly clamped to the foundation using leaf springs, then the structural stability is improved, but vibration transmission between the counterweight and foundation increases causing disruptions and noise
Solution Approach 1:
The patent changes the connection parameter from rigid clamping to rotatable articulation. The spring ends are articulated rotatably instead of being rigidly clamped, allowing the connection to adapt to vibration movements while maintaining structural stability. This parameter change enables the system to filter vibrations through rotational degrees of freedom rather than transmitting them rigidly.
Solution Approach 2:
The patent introduces dynamic capability to the spring connection by allowing rotatable articulation at the spring ends. This dynamic connection can adapt its orientation during operation, absorbing vibration energy through rotational movement while maintaining the required structural support, thus reducing vibration transmission to the foundation.
2Reliability
If rigid clamping is used at both spring ends, then the control strictness is improved, but the transmission of vibrations between counterweight and foundation increases
Solution Approach 1:
The patent modifies the connection parameter from fixed rigid clamping to rotatable articulation. This allows the connection to maintain control and support functions while introducing rotational freedom that prevents vibration transmission. The articulated connection preserves reliability through controlled movement rather than rigid constraint.
3Object-generated harmful factors
If the spring connection is made flexible with rotatable articulation, then vibration transmission is reduced, but the structural rigidity decreases
Solution Approach 1:
The patent employs dynamic rotatable articulation that provides rigidity when needed for structural support while allowing movement to filter vibrations. The articulated connection maintains structural strength through its load-bearing capability while the rotational freedom provides vibration isolation, achieving both requirements simultaneously.
Solution Approach 2:
The patent changes the connection parameter to allow rotational movement while maintaining load-bearing capacity. The articulated spring connection preserves structural rigidity for support functions while introducing rotational flexibility that reduces vibration transmission, achieving both structural strength and vibration isolation.
4Ease of manufacture
If rigid leaf springs are used, then the manufacturing simplicity is improved, but the noise development increases due to vibration transmission
Solution Approach 1:
The patent modifies the connection parameter from rigid clamping to rotatable articulation. This simple parameter change maintains manufacturing ease while fundamentally reducing vibration transmission and associated noise. The articulated connection requires minimal additional manufacturing complexity while achieving significant noise reduction.

Implementation Method 1
the springs of the second group of springs are connected to the foundation at a respective upper spring end and to the counterweight at a respective lower spring end... at least one free spring section is rotatably articulated in the area of its upper end on the foundation and/or in the area of its lower end on the counterweight
Implementation Method 2
at least one free spring section is rotatably articulated in the area of its upper end on the foundation and/or in the area of its lower end on the counterweight... creates a pivot point and thus a vibration radius of the counterweight relative to the Foundation
