Surface Cleaning Head Corner Nozzle Recoil Counterforce
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning heads with rotating nozzles struggle to effectively clean corner areas without risking detachment from the surface due to the repulsive force of additional nozzles.
Innovation Solution
Incorporation of a non-rotatable additional nozzle with an impact element that counteracts the recoil force by directing cleaning liquid onto the impact element, which transfers force to the housing, preventing the cleaning head from lifting off the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional nozzle is added to clean corner areas, then cleaning capability is improved, but the recoil force causes the cleaning head to lift off the surface
Solution Approach 1:
The patent introduces an impact element that redirects the recoil force of the additional nozzle downward onto the surface, creating a counterbalancing effect. The impact element acts as a counterweight mechanism where the redirected jet force opposes the lifting recoil force, allowing the cleaning head to maintain stable contact with the surface while cleaning corner areas.
Solution Approach 2:
The patent converts the harmful recoil force that causes lifting into a beneficial downward pressing force. By positioning the impact element to redirect the jet, the previously harmful recoil force is transformed into a useful force that presses the cleaning head against the surface, improving both stability and cleaning effectiveness.
2Manufacturing precision
If a non-rotatable additional nozzle is used to target corner areas, then precision is improved, but recoil force lifts the cleaning head
Solution Approach 1:
The impact element serves as a counterweight mechanism that balances the recoil force from the fixed additional nozzle. By redirecting the jet onto the impact element, the system creates an opposing force that prevents the cleaning head from lifting, maintaining operational stability while preserving the targeting precision of the fixed nozzle position.
3Stability of the object's composition
If the cleaning head is pressed firmly against the surface to prevent lifting, then stability is improved, but the recoil force reduces cleaning effectiveness
Solution Approach 1:
The patent transforms the harmful recoil force into a beneficial pressing force by redirecting it onto the surface through the impact element. This conversion eliminates the need for external pressing while maintaining stable contact, and simultaneously improves cleaning effectiveness by directing the jet force onto the surface rather than losing it to lifting motion.
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 reliable cleaning of corner areas by compensating the recoil force with a counterforce, ensuring the cleaning head remains securely attached to the surface during use.
Implementation Method 1
The fluid jet emitted by the auxiliary nozzle strikes, outside the circular area defined by the nozzle rotating together with the respective spray arm, partly directly onto the surface to be cleaned and partly onto an impact element assigned to the auxiliary nozzle. The impact of cleaning fluid on the impact element results in the impact element being subjected to a force in the direction of the surface to be cleaned.
Implementation Method 2
The nozzle experiences a recoil, which causes the spray arm to rotate around its axis. This allows a relatively large area to be covered with cleaning fluid in a short time.

AI summary
The invention relates to a surface cleaning head for cleaning a surface, having a dome-shaped housing (11) that is open on one side, in which at least one spray arm (47, 48) having a spray nozzle (52, 53) is rotatably supported about a rotational axis, wherein the nozzle can be subjected to pressurized cleaning fluid and the same revolves about the rotational axis together with the spray arm in order to apply a surface to be cleaned with a fluid jet. In order to refine the surface cleaning head such that corner regions of the surface to be cleaned can also be subjected to a pressurized cleaning fluid in a simple manner, the invention provides that the surface cleaning head has at least one rotationally fixed additional nozzle (60). Said nozzle can be subjected to pressurized cleaning fluid, and an impact element (68) is associated with the same, which can be subjected to cleaning fluid coming from the additional nozzle.
