Rotating Fluid-Dispensing Head for Accessible Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid-dispensing head systems require manual cleaning from beneath, leading to inconvenient and potentially hazardous movements, as the heads are typically fixed with nozzles facing downwards, causing clogging and necessitating awkward postures for operators.
Innovation Solution
A system allowing the fluid-dispensing head to be manually or automatically rotated for easy access and cleaning, featuring an L-shaped bracket for extraction and a mechanism to block fluid supply during cleaning, enabling nozzles to be oriented upwards or towards the operator, thus eliminating the need for contorted positions and preventing accidental fluid movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fluid-dispensing head is fixed with nozzles facing downwards, then the device structure is simple and stable, but the cleaning operation becomes inconvenient and hazardous requiring awkward postures
Solution Approach 1:
The fluid-dispensing head is transformed from a fixed structure to a movable one, capable of rotating between a working position (nozzles facing downwards) and a cleaning position (nozzles facing upwards or towards the operator). This dynamic adjustment allows the head to adapt to different operational requirements, improving cleaning convenience while maintaining structural simplicity through a rotation mechanism rather than complete redesign
Solution Approach 2:
The invention introduces rotational movement as an additional degree of freedom, allowing the fluid-dispensing head to change orientation in a vertical dimension. By rotating the head around a horizontal axis, the nozzles can be reoriented from facing downwards to facing upwards or towards the operator, eliminating the need for awkward bending postures during cleaning operations
2Reliability
If the fluid-dispensing head is fixed in position, then the device structure is simple, but accidental fluid movement cannot be prevented during cleaning
Solution Approach 1:
A blocking mechanism is integrated into the system that can prevent fluid supply in advance before cleaning operations begin. This preliminary action ensures that even if the fluid-dispensing head moves accidentally during cleaning, no fluid will be dispensed, thereby preventing hazardous fluid movements while adding minimal control complexity
Solution Approach 2:
An intermediary blocking mechanism is introduced between the fluid supply source and the nozzles. This intermediary component can be activated to block fluid flow independently of the head position, providing an additional safety layer that prevents accidental fluid movement during cleaning operations without requiring complex interlocking mechanisms
3Productivity
If the nozzles face downwards during operation, then fluid dispensing is efficient, but cleaning requires working from beneath upwards which is inconvenient
Solution Approach 1:
The fluid-dispensing head is designed with rotational capability, allowing it to dynamically switch between the working position (nozzles facing downwards for efficient dispensing) and the cleaning position (nozzles facing upwards or towards the operator for easy accessibility). This dynamic reconfiguration enables the system to optimize for different operational phases without compromising either fluid dispensing efficiency or cleaning convenience
Solution Approach 2:
The system employs periodic action by alternating between two distinct states: during normal operation, the head remains in the working position with nozzles facing downwards for efficient fluid dispensing; during cleaning intervals, the head rotates to the cleaning position with nozzles facing upwards or towards the operator. This periodic switching between configurations allows the system to maintain high productivity during operation while ensuring easy accessibility during maintenance phases

AI summary
A system (1) is for release or movement of a fluid-dispensing head (2) positioned within a dispenser (6) of fluids. The system (1) houses the fluid-dispensing head (2), which has nozzles (3) for the supply of fluids. The system (1) includes a release (7, 10, 20) for release and movement of the fluid-dispensing head (2) configured for enabling movement of the delivery head (2) between a first position of use, in which the nozzles (3) deliver fluids into a container (4), and a cleaning position or second position of use (set facing the operator) or third position of use (facing upwards), distinct from the first position of use, in which they are accessible for being cleaned.
