Parallelogram Linkage for Gravity-Assisted Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing immersion treatment systems require complex and costly designs to lower objects into treatment liquids, often necessitating large installation spaces and significant control technology efforts due to the need for precise vertical movement mechanisms.
Innovation Solution
The connecting structure between the support platform and the object is designed to minimize vertical distance from the axis of rotation, allowing gravity to facilitate vertical movement without additional motor-driven components, utilizing a rotating transport trolley with a parallelogram guide mechanism that unfolds under gravity, enabling complete immersion and efficient vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a motor-driven support platform is used to achieve vertical movement for immersion, then precise control of vertical position is achieved, but device complexity and control technology requirements increase
Solution Approach 1:
The connecting structure uses gravity as the driving force to automatically unfold and lower the object into the treatment liquid, eliminating the need for motor-driven vertical movement control. The structure serves itself by using its own weight to achieve the immersion function.
Solution Approach 2:
The design allows the object to move vertically under gravity without requiring active control to maintain specific positions. The system accepts positions along the gravitational field gradient, eliminating the need for precise position control during immersion.
2Weight of moving object
If elaborate support frames are used to handle high forces for heavy objects, then objects of considerable weight can be immersed, but device complexity and construction costs increase
Solution Approach 1:
The connecting structure transitions from a static rigid support to a dynamic mechanism that unfolds during immersion. The parallelogram linkage allows the structure to adapt its configuration during movement, distributing forces more efficiently without requiring overly robust support frames.
Solution Approach 2:
The connecting structure is divided into multiple linkages (first linkage, second linkage, third linkage) that work together in a parallelogram mechanism. This segmentation allows each component to handle portions of the load and movement, reducing the complexity requirements for the overall support structure.
3Stability of the object's composition
If a rigid connection between object and support platform is used, then structural stability is maintained, but vertical movement requires additional motorized mechanisms
Solution Approach 1:
The connection between the support platform and object transitions from rigid to dynamic. The parallelogram linkage provides a stable geometric relationship while allowing the necessary vertical movement through controlled unfolding, maintaining structural integrity without rigid fixation.
4Speed
If the axis of rotation is located far outside the contour of the vehicle body, then rotational movement is achieved, but installation space in the vertical direction increases
Solution Approach 1:
The connecting structure folds up in the transport position, nesting the linkages in a compact configuration above the support platform. During immersion, the structure unfolds to achieve the necessary vertical distance, providing both compact transport and adequate operational space.

AI summary
A description is given of an immersion treatment installation (1), which comprises at least one immersion tank (2) in a way known per se. A conveying system (4, 5) brings the items (3) to be treated up to the immersion tank (2), into the space inside the immersion tank (2), out of it and away from it. The conveying system (4, 5) comprises at least one transporting carriage (5), which has a carrying platform (14), which is pivotable about a pivot axis (15) and to which at least one item (3) can be fastened with the aid of a connecting structure (18, 19, 20, 21, 22). This connecting structure (18, 19, 20, 21, 22) is movable on its own to such an extent that, with increasing pivoting from the unimmersed position, the distance between the item (3) and the pivot axis (15) becomes increasingly greater under the influence of gravitational force.
