Trolley Washing Chamber Top-Fed Fluid Connection Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing apparatuses for trolley-type objects face inefficiencies due to the placement of hydraulic pipes, leading to interference with impellers, reduced productivity, risk of leakages, and uneven distribution of washing liquid, resulting in ineffective washing cycles.
Innovation Solution
The washing apparatus features a hydraulic connection pipe mounted on the upper wall, selectively movable to connect with a connector element on the trolley's frame, allowing for vertical fluid distribution without interference and optimizing fluid use, eliminating the need for a lower compartment and counter-thrust elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hydraulic pipe is disposed on the bottom of the washing chamber, then the pipe can be selectively connected to the delivery element, but it interferes with the impellers and reduces their diameter
Solution Approach 1:
The hydraulic connection pipe is moved from the bottom wall to the upper wall of the washing chamber, changing its spatial dimension. This allows the pipe to connect to the delivery element from above without interfering with the impellers located at the bottom, thus maintaining both selective connection capability and washing effectiveness
2Ease of operation
If the hydraulic pipe is disposed on the bottom of the washing chamber, then connection is possible, but a lower compartment must be provided to house the pipe and connections
Solution Approach 1:
The hydraulic connection pipe and its connections are extracted from the lower compartment and relocated to the upper wall of the washing chamber. This eliminates the need for a separate lower compartment to house these components, thereby reducing structural complexity while maintaining connection functionality
3Ease of operation
If the hydraulic pipe is disposed on the bottom of the washing chamber, then connection can be made, but leakages may occur to the floor around the apparatus
Solution Approach 1:
The hydraulic connection pipe is relocated from the bottom wall to the upper wall of the washing chamber. This dimensional change positions the pipe and its connections away from the floor level, eliminating the risk of leakages reaching the floor around the apparatus while preserving the selective connection capability
4Ease of operation
If the hydraulic pipe is disposed laterally, then connection is possible, but it interferes with the baskets or impellers
Solution Approach 1:
The hydraulic connection pipe is positioned on the upper wall of the washing chamber, utilizing the vertical dimension rather than lateral or bottom positions. This eliminates interference with baskets and impellers that occupy the lateral and bottom spaces, thereby maintaining both connection capability and washing effectiveness
5Ease of operation
If the hydraulic pipe is disposed laterally, then connection can be made, but a counter-thrust element is needed to prevent trolley movement
Solution Approach 1:
The hydraulic connection pipe is relocated from a lateral position to the upper wall of the washing chamber. This vertical positioning eliminates the need for counter-thrust elements to prevent trolley movement or turning, as the pipe connection from above does not create lateral forces, thereby reducing structural complexity
6Ease of operation
If the hydraulic pipe is disposed laterally, then connection is possible, but unequal distribution of washing liquid occurs
Solution Approach 1:
The hydraulic connection pipe is positioned on the upper wall of the washing chamber, providing a central and symmetrical connection point for the delivery element. This vertical alignment ensures equal distribution of washing liquid to all impellers, achieving uniformity in the washing process while maintaining connection capability
7Ease of operation
If the pipe is connected from the bottom, then connection is possible, but gravity reduces outlet pressure to the impellers
Solution Approach 1:
Instead of connecting the hydraulic pipe from the bottom and fighting against gravity, the pipe is inverted to connect from the upper wall downward. This allows gravity to assist the flow of washing liquid to the impellers, maintaining optimal outlet pressure and connection capability

AI summary
A washing apparatus (10) comprises a washing chamber (12) delimited by two lateral walls (14), a bottom wall (16) and an upper wall (18), and is provided at the front with an inlet aperture for inlet and/or outlet. The apparatus (10) also comprises a main distribution circuit of a treatment fluid, to distribute the treatment fluid inside the washing chamber (12), a trolley-type movement device (28) able to be inserted into the washing chamber (12) and comprising a frame (30) to support objects to be subjected to a washing cycle in the washing chamber (12) and on which distribution elements (34) for the treatment fluid are mounted. The frame (30) is formed by hollow tubular elements to function as a secondary distribution circuit of the washing liquid towards the distribution elements (34). The apparatus (10) comprises at least a connector element (40) located on the upper part of the frame (30) and which functions as a delivery element of the secondary distribution circuit and a hydraulic connection pipe (36) mounted on the upper wall (18), which is able to connect hydraulically the main distribution circuit to the connector element (40) of the secondary distribution circuit. The hydraulic connection pipe (36) is selectively movable vertically between a first position connected to the connector element (40) and a second position separate from the connector element (40).
