Load platform for a cleaning appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load carriers for automatic cleaning machines often result in forgotten wash arms during assembly, leading to substandard cleaning performance and the need for repetitive cleaning or disinfection, which is time, cost, and energy intensive.
Innovation Solution
A modular load carrier design with a support frame, parallel load carrier tiers, and a removable tier equipped with a rotatably mounted wash arm and supply line, ensuring the wash arm and supply line are always connected and easily removable, preventing incorrect manipulations and maintaining consistent cleaning standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wash arms are separately assembled onto load carrier levels, then flexibility in configuration is improved, but reliability deteriorates due to forgotten wash arms during assembly
Solution Approach 1:
The wash arm is integrated with the load carrier level as a single removable unit. The load carrier level includes a support structure with a rotatably mounted wash arm, where the wash arm's supply line is connected to the support structure. This merging ensures that when the load carrier level is removed or installed, the wash arm is always included, eliminating the risk of forgotten wash arms while maintaining configuration flexibility.
2Reliability
If multiple supply lines are used for fluid supply, then reliability is improved through redundancy, but device complexity increases
Solution Approach 1:
The patent extracts the fluid supply function from a single complex supply line and implements it through multiple independent supply lines (first and second supply lines). Each supply line can independently supply fluid to the wash arm. This extraction creates redundancy where if one supply line fails, the other can still provide fluid, improving reliability without requiring a single overly complex system.
3Ease of operation
If load carrier levels are made removable for loading bulky objects, then ease of operation is improved, but manufacturing precision deteriorates due to incorrect assembly
Solution Approach 1:
The wash arm is merged with the load carrier level as an integrated unit. The support structure of the load carrier level includes the rotatably mounted wash arm with its supply line connection. This integration ensures that when load carrier levels are removed for loading bulky objects and then reinstalled, the wash arm is always correctly positioned and connected, eliminating assembly errors while maintaining operational flexibility.
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 design ensures constant and standard cleaning performance by preventing wash arm forgetfulness, optimizing space usage, and allowing for ideal fluid distribution, thereby reducing operational errors and energy consumption.
Implementation Method 1
The axis of rotation of the wash arm can run through the intersection of the diagonals of the assigned load carrier level. This achieves an ideal distribution of the fluid in the cleaning chamber of the cleaning machine.
Implementation Method 2
at least one supply line for supplying the wash arm with a fluid
Implementation Method 3
a support frame with a lower load carrier level and an upper load carrier level, which are arranged parallel to one another and are connected to one another by spacers

AI summary
A load carrier (1) for a cleaning machine is proposed. The load carrier (1) comprises a support frame with a lower load carrier level (2) and an upper load carrier level (3), which are arranged parallel to one another and are connected to one another by spacers (5, 6). Furthermore, the load carrier (1) comprises at least one further removable load carrier level (11) which is detachably fastened parallel to the upper and lower load carrier levels (2, 3) on the support frame, preferably can be pushed into it. The removable load carrier level (11) comprises a rotatably mounted washing arm (10) and at least one supply line (8) for supplying the washing arm (10) with a fluid.
