Lifting Apparatus Inclined Surface Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lifting apparatuses suffer from low stability, especially when lifting heavy objects, as they tend to fall under pressure, leading to poor positioning accuracy and increased risk of skewing.
Innovation Solution
The proposed lifting apparatus incorporates a first actuator with a movable actuating rod that moves in a first direction, connected to a movable component with an inclined surface. This configuration allows the lifting component to move in a second direction, different from the actuating rod's direction, thereby enhancing stability and self-locking during lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the actuating rod moves in the same direction as the lifting component, then the structure is simple, but the lifting apparatus falls under pressure and loses stability when lifting heavy objects
Solution Approach 1:
The patent changes the motion direction of the actuating rod from the lifting direction to a direction intersecting with the lifting direction. The actuating rod moves in a first direction that intersects with the second direction (lifting direction) at an angle between 0-45 degrees, preventing the actuating rod from directly bearing the full lifting load while maintaining structural simplicity.
Solution Approach 2:
The patent introduces an angle parameter between the actuating rod's motion direction and the lifting component's motion direction. By controlling this angle to be between 0-45 degrees, the system optimizes the force distribution, preventing the actuating rod from moving under pressure while maintaining ease of manufacture.
2Reliability
If the actuating rod moves in a different direction from the lifting component, then the stability and positioning accuracy improve, but the device complexity increases
Solution Approach 1:
The patent implements a spatial arrangement where the actuating rod moves in a first direction and the lifting component moves in a second direction that intersects with the first direction. This dimensional change allows the actuating rod to push the lifting component via an inclined surface without requiring complex multi-axis mechanisms, achieving stable lifting with relatively simple structure.
Solution Approach 2:
The patent introduces a lifting component with an inclined surface as an intermediary between the actuating rod and the load. The actuating rod pushes the lifting component along its motion direction, and the inclined surface converts this motion into vertical lifting motion, simplifying the overall mechanism while improving stability.
3Device complexity
If the actuating rod is directly connected to the lifting component, then the structure is compact, but the machining accuracy requirements are high and manufacturing costs increase
Solution Approach 1:
The patent introduces a movable component as an intermediary between the actuating rod and the lifting component. This movable component with an inclined surface allows for easier manufacturing by distributing the machining requirements across multiple simpler parts rather than requiring high precision on a single direct connection.
Solution Approach 2:
The patent divides the connection system into separate components: the actuating rod, the movable component with inclined surface, and the lifting component. This segmentation allows each part to be manufactured independently with lower precision requirements, reducing overall manufacturing difficulty and cost.
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
The solution significantly improves the stability and accuracy of the lifting process by preventing the actuating rod from moving under pressure, even when lifting heavy loads, thus reducing the risk of skewing and ensuring precise positioning.
Implementation Method 1
The movable component has an inclined surface, and the inclined surface is configured to exert a force on the lifting component when the movable component moves, so that the lifting component moves in the second direction
