Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for dispensing mixtures, such as steam suction devices, are cumbersome due to the weight of attached fluid containers, making precise guidance difficult and leading to user fatigue, and lack the ability to adapt cleaning intensity to contamination levels.
Innovation Solution
A device featuring a line for guiding compressed air, with a valve system to control the air and fluid flow, allowing for a mixed compressed air-fluid mixture to be dispensed eccentrically, enabling adjustable cleaning intensity and efficient removal of dirt particles and cleaning liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a fluid reservoir is attached to the handle, then the device can dispense cleaning fluid, but the user's arm fatigues quickly due to increased weight
Solution Approach 1:
The patent extracts the fluid reservoir from the handle and relocates it to a separate, mobile container that can be positioned on the floor or mounted on a cart. This separation removes the weight burden from the user's arm while maintaining adequate fluid capacity for cleaning operations.
Solution Approach 2:
The patent transitions from a handheld configuration to a floor-standing or wall-mounted configuration, moving the device from the horizontal dimension (handheld) to the vertical dimension (floor-standing). This dimensional change eliminates arm fatigue while preserving cleaning functionality.
2Quantity of substance
If a fluid reservoir is attached to the handle, then the device can dispense cleaning fluid, but it becomes difficult to guide the device precisely
Solution Approach 1:
By extracting the fluid reservoir from the handle, the patent restores balance and maneuverability to the handheld component. The separated reservoir system allows precise guidance of the cleaning device without the destabilizing effect of an attached weight.
3Device complexity
If compressed air and fluid are mixed in fixed proportions, then the mixing process is simple, but the cleaning intensity cannot be adapted to different contamination levels
Solution Approach 1:
The patent incorporates adjustable valves or flow control mechanisms that allow dynamic modification of the compressed air-to-fluid ratio. This enables adaptation of cleaning intensity to match varying contamination levels while maintaining a relatively simple mixing system architecture.
Solution Approach 2:
The patent enables change of flow rate parameters for both compressed air and fluid independently, allowing the system to adapt cleaning intensity by adjusting these parameters according to the degree of contamination without significantly increasing system complexity.
4Device complexity
If the outlet device is fixed along the longitudinal axis, then the structure is simple, but the mixture cannot be dispensed eccentrically for optimal cleaning coverage
Solution Approach 1:
The patent employs an asymmetric outlet device configuration where the spray nozzle is positioned eccentrically relative to the longitudinal axis of the compressed air line. This asymmetric arrangement optimizes cleaning coverage by directing the mixture toward the surface at an optimal angle while maintaining relatively simple structural construction.
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
The device reduces user fatigue by distributing weight more evenly, allows for precise control of cleaning intensity based on contamination, and effectively removes dirt and cleaning liquid, improving cleaning efficiency.
Implementation Method 1
The released fluid is captured and entrained by the compressed air flow in the connecting flange and/or the outlet device

AI summary
A system for dispensing a mixture, which can be produced from at least one gas flow and at least one fluid flow, onto a surface (50). The mixture (14) can be fed to a device (7) for dispensing the mixture (14). The device (7) for dispensing the mixture (14) comprises a gas-conducting line (2), in the interior (39) of which there axially extends a fluid-conducting line (5). The gas-conducting line (2) and the fluid-conducting line (5) are designed as an outlet device (4) for dispensing the mixture (14). The outlet device (4) is furthermore designed so as to be rotatable eccentrically with respect to and around the longitudinal axis (12) of the gas-conducting line (2), and furthermore so as to have a body (59) for cleaning the surface (50).
