Mopping Chassis Auto-Braking to Prevent Roll-Away During Wringing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning trolleys and devices tend to roll away unintentionally during washing and drying processes, leading to instability and potential tipping, and require complex operation to secure against movement.
Innovation Solution
A wiper system with a chassis featuring a braking device that automatically switches to a blocking position under load from a wiper press or mop weight, allowing for secure movement and easy handling without additional levers, using a combination of wheels and a braking platform with a brake element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the chassis is designed to be freely movable on wheels for easy handling during floor cleaning, then the ease of operation is improved, but the stability deteriorates when washing or drying the wiping device as the chassis may roll away unintentionally
Solution Approach 1:
The braking device is designed to dynamically switch between release and blocking positions based on the applied force. During normal operation, the brake is released for free movement. When the wiper press is actuated or a mopping device is placed in the receptacle, the increased force automatically engages the brake to prevent rolling, providing adaptive stability without compromising ease of movement during cleaning tasks.
2Stability of the object's composition
If a braking device is added to prevent rolling away during washing and drying, then the stability is improved, but the device complexity increases due to additional components and operation requirements
Solution Approach 1:
The braking device operates automatically based on the force applied to the wiper system mount. When the wiper press is actuated or a mopping device is placed in the receptacle, the force exceeds the switching triggering force and automatically engages the brake without requiring separate operation. This self-activating mechanism prevents rolling during critical processes while avoiding the need for additional operating levers or complex control systems.
3Stability of the object's composition
If a locking device for wheels is implemented to secure the chassis, then the stability is improved, but the ease of operation deteriorates as the user must park the cleaning device completely in the receptacle or operate additional controls
Solution Approach 1:
The braking device automatically engages when the force from the wiper press or mopping device weight exceeds the switching triggering force, and automatically releases when the force falls below the threshold. This eliminates the need for users to manually operate brake levers or completely park the device in a receptacle to secure it, maintaining ease of operation while ensuring stability during washing and drying processes.
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
Enables secure and effortless movement during floor cleaning, automatically preventing rolling and falling, enhancing handling efficiency and safety by eliminating the need for additional operational controls.
Implementation Method 1
the braking device is designed in such a way that the force (23) can be applied to the wiper system mount (3) and when the wiper system mount (3) with the bucket (9) and the drying device does not switch into the blocking position
Implementation Method 2
the braking device has at least one braking element, for example a brake pad. It can advantageously be provided that the braking element stands on the chassis to block the chassis with the ground and/or comes into contact with at least one wheel of the chassis

AI summary
Disclosed is a chassis comprising a mopping system receptacle (3) for accommodating a mopping system, particularly a mopping system with a bucket and/or a cloth squeezer and/or a cloth centrifuge. The inventive chassis further comprises a braking device (17, 19, 21) which switches the chassis from an unblocked position, in which the chassis can be moved, especially rolled, into a blocked position, in which the chassis is blocked and is secured against rolling off, when a force is applied to the mopping system receptacle.
