Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional cleaning trolley design is used, then structural stability is maintained, but adaptability to customer needs deteriorates
Solution Approach 1:
The cleaning trolley is divided into modular components including removable cross walls, interchangeable wall elements, and separable frame sections. Each cross wall consists of two separate wall elements that can be independently selected and attached, allowing customization of the trolley's interior configuration to meet different customer requirements while maintaining a manageable structural complexity through standardized connection mechanisms.
2Adaptability or versatility
If modular design with multiple units is implemented, then adaptability improves, but handling difficulty increases
Solution Approach 1:
Multiple independently mobile units are designed with complementary connection mechanisms that allow them to be easily joined together. The cross walls feature standardized attachment points and interlocking elements that enable quick assembly and disassembly without requiring complex tools or procedures, thus maintaining handling ease while achieving modular configurability.
3Ease of operation
If lateral doors with conventional hinges are used, then door functionality is achieved, but trolley bulkiness increases
Solution Approach 1:
Instead of using conventional hinges that protrude outward from the trolley body, the hinge mechanism is inverted or recessed into the trolley structure. This allows the lateral doors to be mounted with minimal external protrusion, maintaining smooth contours and reducing overall trolley volume while preserving full door opening and closing functionality.

AI summary
The present invention refers to a cleaning trolley comprising a base plate supported by rolling members; at least four upright hollow profiles for fixing cross walls arranged on the base plate, wherein each cross wall consists of two separate wall elements removably arranged back-to-back to each other and fixed by said upright hollow profiles; and an upper frame for securing the at least four upright hollow profiles. Further, the invention provides a cleaning trolley comprising a primary section and a secondary section, each section having a base plate supported by rolling members, wherein the primary section and the secondary section are removably connected by a connection mechanism, which connection mechanism contains a pedal pivotably attached to the bottom side of the base plate of the secondary section, and its actuation releases claws which in connection position are engaged with the primary section.
