Lift Table Mechanism with Single Drive and Switching Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with lifting tables, such as propellant charge rammers, often have complex structures due to multiple drives and control systems, increasing the risk of failure and requiring separate drives for different movements.
Innovation Solution
The drive is connected to the lifting table via switching means, allowing for both actuation and linear movement in a single direction without a separate drive, simplifying the structure and reducing failure risks by enabling independent movements in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate drive is provided for each movement direction, then the device can achieve multiple independent movements, but the device complexity increases
Solution Approach 1:
The single drive unit is designed to perform multiple functions: it can actuate the lifting table in the vertical direction and move the lifting table linearly in the transverse direction through the switching means. This multi-functionality eliminates the need for separate drives for each movement direction, reducing device complexity while maintaining full movement capability
Solution Approach 2:
The patent combines the functions of multiple drives into a single drive unit by introducing switching means that can connect the drive to the lifting table in different configurations. The drive and switching means together form an integrated system that replaces what would traditionally require multiple separate drive units
2Adaptability or versatility
If multiple drives and control devices are used, then the device can perform complex movements, but the risk of failure increases
Solution Approach 1:
The single drive unit with switching means serves multiple movement functions, reducing the total number of drive components. Fewer drives and control devices mean fewer potential failure points, thereby improving reliability while maintaining the ability to perform both vertical actuation and transverse movement
3Device complexity
If switching means are introduced to enable single drive for multiple movements, then the device complexity is reduced, but the control complexity increases
Solution Approach 1:
The switching means are designed to switch automatically based on the position and operational state of the lifting table. The system self-regulates the connection between the drive and the lifting table without requiring complex external control signals, reducing control complexity while enabling the drive to perform multiple functions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration simplifies the structure, reduces the risk of failure, and allows for efficient movement in two independent directions, including transverse movement of the propellant charge receptacle, enhancing operational reliability and space efficiency.
Implementation Method 1
The lifting table has two scissor arms, the end of which on the drive side is coupled to the switching means. The scissor arms can be pivotally connected to one another, so that the lifting movement of the lifting table can be generated by a pivoting movement of the scissor arms relative to one another.
Implementation Method 2
The drive-side end of the second scissor arm is preferably coupled to the drive via a spindle, so that the drive-side end of the second scissor arm can be moved translationally along the spindle.
