Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mineral material processing systems, such as vibrating screens and feeders, require complex structures with synchronized drive shafts to generate an elliptical movement path, making them cumbersome and difficult to adjust.
Innovation Solution
A vibrating aggregate that uses a single rotatable shaft with a first element moving along a circular path and a second element moving linearly, perpendicular to the shaft's axis, to generate an elliptical path for mineral material processing devices like screens and feeders, allowing for adjustable ellipticity and direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If two or more drive shafts with eccentric masses are used to generate elliptical movement, then the elliptical path can be formed, but the device complexity increases due to synchronization requirements
Solution Approach 1:
The patent combines the functions of multiple drive shafts into a single drive shaft by integrating two eccentric masses (first and second eccentric masses) on the same shaft. This merging eliminates the need for complex synchronization mechanisms between separate shafts while maintaining the elliptical movement generation capability through the combined effect of the two eccentric masses rotating in different phases
Solution Approach 2:
The patent segments the elliptical movement generation into two independent eccentric masses mounted on the same shaft. Each eccentric mass generates a circular motion component, and their combination produces the elliptical path. This segmentation allows independent design and adjustment of each eccentric mass while simplifying the overall drive system structure
2Shape
If spring suspension and rotating eccentric masses are used to produce elliptical movement, then the vibrating screen can move along an elliptical path, but the structure becomes complex
Solution Approach 1:
The patent merges the functions of spring suspension and rotating eccentric masses into a single integrated aggregate structure. The eccentric masses are directly mounted on the drive shaft that is supported by the frame, eliminating the need for separate spring suspension systems while maintaining the elliptical movement capability through the combined elastic and inertial effects
3Shape
If multiple drive shafts are synchronized by gearing or cogged belts, then elliptical movement can be generated, but the ease of operation decreases
Solution Approach 1:
The patent combines multiple drive functions into a single drive shaft, eliminating the need for complex synchronization mechanisms. The phase difference between the two eccentric masses is achieved through their geometric arrangement and mounting positions rather than through complex gear or belt synchronization, significantly improving ease of operation and adjustability
Solution Approach 2:
The patent employs dynamic adjustment capabilities where the ellipticity and direction of the elliptical path can be modified by changing the positions or masses of the eccentric masses while maintaining a single drive shaft. This dynamic adjustability is much easier to implement than synchronizing multiple shafts and allows flexible adaptation to different processing requirements
