Dip-Treatment Plant Skid Transportation System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dip-treatment plants for motor vehicle bodies face issues of high costs, large volumes, and reliability problems due to complex and bulky transportation systems that contaminate process liquids and require excessive space and liquid usage.
Innovation Solution
A plant with a skid transportation system featuring parallel travel ways along the tank's edges and a motor-driven shaft for controlled rotation of the body, allowing for efficient immersion and overturning without entering the liquid, thus reducing tank size and liquid usage while maintaining flexibility and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transportation system enters into the treatment tank to perform immersion and overturning operations, then the immersion and overturning operations can be performed, but the transportation system contaminates the process liquid and requires large tank volumes
Solution Approach 1:
The patent extracts the transportation system from the treatment tank, positioning it entirely outside the tank. The skid with the body is transported above the tank, and only the body is immersed in the process liquid during treatment. This eliminates contamination of the process liquid by transportation system components while maintaining the immersion and overturning operations through external mechanical means.
2Ease of operation
If the transportation system is positioned above and inside the tank, then the immersion treatment can be performed, but the system exposes transportation components to process liquids causing reliability and cleanliness problems
Solution Approach 1:
The transportation system is completely extracted from the treatment environment. The skid transportation system operates entirely above the tank on external rails, and the body is lowered into the process liquid only for the actual treatment operation. This separation ensures that no transportation components are exposed to process liquids, eliminating reliability and cleanliness problems associated with liquid exposure.
3Ease of operation
If the skid transportation line has different heights to be completely immersed in treatment tanks, then the body can enter and exit tanks gradually, but the system requires very long tanks and is very slow
Solution Approach 1:
Instead of using vertical height variations to achieve gradual immersion, the patent employs horizontal movement combined with mechanical lowering. The skid is transported horizontally above the tank, and the body is lowered vertically into the process liquid only when needed. This dimensional approach allows rapid positioning without requiring long tanks or slow gradual immersion, significantly improving productivity.
4Ease of operation
If the transportation system passes above the vertical axis of the tanks, then loading and unloading operations can be performed, but the plant becomes bulky and productivity is average
Solution Approach 1:
The patent merges the transportation function and the immersion operation function into a single integrated system. The skid transportation system serves both to transport the body and to position it for immersion by lowering it vertically into the tank. This combination eliminates the need for separate loading/unloading areas and reduces overall plant volume while maintaining operational ease.

Function Achieved in This Case
The solution enables a compact, cost-effective, and reliable dip-treatment process with reduced liquid consumption and contamination, improving operational efficiency and flexibility.
Implementation Method 1
a shaft (21) arranged transverse to the transportation line and rotatable about an axis so as to overturn the body between a first upper advancing position and a second lower position immersed inside the tank
Implementation Method 2
a motor unit (23) arranged on the outside of the tank along one of the two lateral edges of the tank and provided with coupling means for connection to the shaft (21) of the skid, situated over the tank, for controlled rotation of the shaft about the axis

AI summary
A plant for clip-treatment of bodies may include: at least one skid configured to support a body to be treated; at least one tank; a transportation line; and/or a system for overturning and immersing the body on the at least one skid which has been positioned above the at least one tank using the line. The line may include travel ways arranged along lateral edges of the at least one tank. The at least one skid may include lateral mounting elements which rest on the ways for supporting and moving the at least one skid above the at least one tank. The overturning and immersing system may include, on the at least one skid, a support for the body rigidly connected to a shaft transverse to the line, and which is configured to overturn the body between a first position and second position immersed inside the at least one tank.
