Transport Trolley with Open-Side Frame for Easy Basket Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trolleys for rinsing baskets in cleaning and disinfection devices are cumbersome to handle due to the need to apply lateral force and navigate around the trolley to position the basket correctly, leading to increased effort and risk of tilting, especially for heavier baskets and shorter users.
Innovation Solution
A trolley design with an open side facing away from the cleaning and disinfection device allows direct access between support rails, featuring transverse connecting struts for stability, and separate rollers for the basket and drip tray to facilitate smooth movement and prevent tilting, along with a detachable tub for easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support frame has a closed structure with connecting struts on both sides, then the structural stability is improved, but the ease of operation deteriorates as users must step around the trolley to push baskets
Solution Approach 1:
The support frame is segmented into two distinct configurations: a stable transport configuration with connecting struts on both sides, and an open loading configuration with the second connecting strut removed. This segmentation allows the trolley to switch between stability and ease of operation based on operational needs.
Solution Approach 2:
The support frame transitions from a static closed structure to a dynamic structure that can be reconfigured. The second connecting strut can be selectively removed or positioned to create an open side, allowing the frame to adapt between stable transport mode and easy-loading mode.
2Productivity
If users apply lateral force to push the rinsing basket from the side, then the basket can be moved into the rinsing chamber, but the basket may tilt on the support rails increasing effort required
Solution Approach 1:
The support frame dynamically changes from a closed structure during transport to an open structure during loading, creating a clear path that guides users to push from the front rather than the side, preventing tilting.
Solution Approach 2:
The open support frame configuration acts as an intermediary that facilitates proper pushing technique by physically guiding the user's approach direction, eliminating the need for lateral pushing that causes tilting.
3Ease of operation
If the support frame is designed with an open side for easy access, then the ease of operation is improved, but the structural stability deteriorates
Solution Approach 1:
The support frame is segmented into essential structural elements (first connecting strut, support rails) that maintain stability, and optional elements (second connecting strut) that can be removed to create open access without compromising core structural integrity.
Solution Approach 2:
The support frame transitions from a static closed structure to a dynamic structure that can be reconfigured. The second connecting strut can be selectively removed or positioned to create an open side, allowing the frame to adapt between stable transport mode and easy-loading mode.

AI summary
The invention relates to a transport trolley for dishwashing baskets of a cleaning and disinfection device, comprising a support frame (8) which has two spaced-apart support rails (10, 11) for receiving a dishwashing basket (5). To provide a transport trolley that simplifies handling for the user, the invention proposes a transport trolley of the type mentioned above, characterized in that the support frame side (15) extending in the spacing direction (13) on one side of the support rails (10, 11) is open.
