Screed End Gate Assembly Single Actuator Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endgates for screeds require operation of two independent adjustment means to control the elevation and orientation of wear shoes, making the process cumbersome and inefficient.
Innovation Solution
An assembly comprising a first member, a second member adjacent to the first member, and a first actuator that rotates the second member while transferring a biasing force, along with a second actuator for translation, allowing for single-actuator operation to adjust the wear shoe's position and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two independent adjustment means are used to control elevation and orientation of wear shoes, then the adjustment precision is improved, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines two independent adjustment means (elevation adjustment and orientation adjustment) into a single integrated actuator mechanism. This single actuator simultaneously controls both the elevation and orientation of the wear shoe, reducing device complexity while maintaining adjustment precision through coordinated motion control.
Solution Approach 2:
The single actuator is designed to perform multiple functions: it simultaneously adjusts both the elevation and orientation of the wear shoe. This multi-functional design eliminates the need for separate adjustment mechanisms, thereby reducing device complexity while preserving comprehensive adjustment capability.
2Measurement precision
If two independent adjustment means are used to control elevation and orientation of wear shoes, then the adjustment precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent merges two independent adjustment operations into a single actuator that simultaneously controls both elevation and orientation. This integration allows the operator to adjust both parameters with one operation, significantly improving ease of operation while maintaining the precision benefits of controlled adjustment.
Solution Approach 2:
The single actuator is designed with universal functionality to perform both elevation and orientation adjustments. This multi-functional design simplifies the operating procedure, allowing one component to handle multiple adjustment tasks that previously required separate mechanisms, thereby improving ease of operation.
3Ease of operation
If a single actuator is used for translation and rotation, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The single actuator is designed with segmented functional components that independently handle translation and rotation tasks. By dividing the actuator into functional segments (translation mechanism and rotation mechanism integrated within one unit), the design achieves ease of operation through single-actuator control while managing complexity through modular functional segmentation.
Solution Approach 2:
The actuator operates in multiple dimensional spaces simultaneously - it provides both linear translation and rotational movement. By designing the actuator to function across different motion dimensions (linear and angular), the system achieves versatile control capability while maintaining a unified actuator structure, balancing ease of operation with manageable complexity.
