Cleaning cart
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning carts are not compact or space-efficient, as their design is determined by the dimensions of the modules they carry, and the boundary surface or line often protrudes beyond the modules, leading to instability and inefficiency in module placement and transportation.
Innovation Solution
A cleaning cart with a basic body that supports modules in a positive-locking, frictional, and/or friction-locking manner, allowing the module's bottom region to project beyond the boundary surface or line, enabling secure carriage and transportation of differently sized modules in a compact design, with features like recesses, saddle struts, and anti-drip mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the boundary surface or line of the cleaning cart protrudes beyond the modules, then the cart provides a larger base area for stability, but the cart becomes less compact and more space-consuming
Solution Approach 1:
Instead of making the boundary surface protrude beyond the modules to achieve stability, the invention inverts the approach by allowing the module bottom region to protrude beyond the boundary surface. The stability is achieved through positive-locking and frictional connections between the module and basic body, rather than through a larger base area. This inversion resolves the contradiction by achieving stability without increasing the cart's overall volume.
2Adaptability or versatility
If the installation spaces are made larger to accommodate different module sizes, then the cart can carry more varied modules, but the cart's compactness is reduced
Solution Approach 1:
The basic body is designed with universal coupling elements that can accommodate modules of different sizes through positive-locking and frictional connections. The boundary surface is defined independently of module dimensions, allowing the same basic body to securely carry various module sizes without requiring enlarged installation spaces. This universality achieves adaptability while maintaining compactness.
3Reliability
If the module is securely locked to prevent tipping, then the module is tip-resistant during transport, but the module cannot project beyond the boundary surface
Solution Approach 1:
The module connection system is segmented into two functional zones: a locking zone within the boundary surface that provides positive-locking and frictional connections for tip-resistance, and a projection zone where the module bottom region can extend beyond the boundary surface. This segmentation allows the module to be securely locked against tipping while simultaneously allowing it to project beyond the boundary surface for compact arrangement.

AI summary
A cleaning cart has a basic body, wherein the lateral extent of the basic body is bounded by an outer circumferential boundary surface or boundary line, and wherein the basic body bears at least one module which is coupleable to the basic body, is configured such that cleaning cart can bear a multiplicity of modules of different size while having a very compact and space-saving design, in that the module is assigned to the basic body in such a positive, frictional and/or non-positive manner preventing tilting that the base region of the module projects at least on one side beyond the boundary surface or boundary line of the basic body.
