Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispenser devices are unsatisfactory for dispensing large quantities of liquid with powerful nebulization, as they either fail to provide fine nebulization or are not suitable for high-volume applications.
Innovation Solution
A dispenser device with a mechanically coupled dispenser head featuring a high resistance spring for pressure generation and a low resistance spring for return, combined with a lever mechanism and rotating nozzle, allowing for efficient manual activation and precise control of liquid dispensing, resulting in fine nebulization and high-volume dispensing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a trigger dispenser is used for large quantities of liquid, then the dispensing volume is increased, but the nebulisation quality deteriorates to coarser drops
Solution Approach 1:
The patent changes the physical parameters of the liquid delivery system by introducing a high-resistance spring to increase pressure and a specific nozzle geometry to optimize droplet formation. This allows large volumes to be dispensed while maintaining fine nebulisation quality through controlled pressure and droplet size parameters
2Manufacturing precision
If a finger pump is used for fine nebulisation, then the droplet size is reduced, but the dispensing volume is limited to small quantities
Solution Approach 1:
The patent merges the fine nebulisation mechanism of finger pumps with the high-volume capability of trigger dispensers. By combining a manual activation lever with a high-resistance spring and optimized nozzle, it achieves both fine droplet size (60 μm) and large dispensing volumes (0.6 ml) in a single device
3Use of energy by moving object
If manual activation is used for high-volume dispensing, then the power consumption is reduced, but the activation force required increases
Solution Approach 1:
The patent uses a dynamic spring mechanism that stores and releases energy during the dispensing cycle. The high-resistance spring requires significant force during compression (activation) but then provides sustained pressure for the entire dispensing duration, reducing the need for continuous power input and enabling manual operation
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 achieves fine nebulization with large doses, maintaining droplet size around 60 μm and dispensing 0.6 ml, with a range of 1 m and a wide aperture cone angle of 35°/40°, suitable for air fresheners, enabling effective product distribution over a wider area.

AI summary
A dispenser head (1) comprises a main body (2), an arm (60) hinged to the main body (2) and pumping means. The pumping means comprise a main cylinder (12), a sliding piston (16), dispensing means sensitive to pressure. The arm (60) is hinged to the main body (2) in a hinging portion (60b) distanced radially from the body axis (X), straddling the body axis (X) and transmitting an axial translation movement to the piston (16) by means of an elastically yielding element (30).
