Trigger Diffuser Blocking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger diffusers for vials are cumbersome, require excessive material, and have high precision manufacturing needs due to complex designs that can lead to accidental actuation and structural weaknesses under pressure.
Innovation Solution
A compact diffuser design with a trigger secured by articulation means and a vertical wall that blocks or releases the trigger's movement based on its alignment, reducing the number of parts and eliminating the need for precise alignment, while ensuring the rib exerts a force orthogonal to the wall for effective blocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the locking means are located on the pivot side of the trigger, then the trigger can be blocked effectively, but the trigger must have sufficient thickness not to bend under pressure, increasing manufacturing costs
Solution Approach 1:
The patent repositions the blocking means from the pivot side of the trigger to the free end of the trigger, changing the spatial dimension of the blocking mechanism. This allows the blocking function to be achieved without requiring increased trigger thickness, as the blocking now occurs at the operational end rather than at the pivot connection point.
2Reliability
If the rib exerts a downwardly-oriented force parallel to the wall of the locking sleeve, then the locking is ensured, but a slight deformation of the pieces can result in misalignment and make the locking means ineffective
Solution Approach 1:
Instead of having the rib exert force parallel to the wall of the locking sleeve (downwardly-oriented), the patent inverts the force direction to be perpendicular to the wall. This changes the blocking mechanism from relying on precise parallel alignment to relying on perpendicular contact, which is less sensitive to manufacturing deformations.
3Ease of operation
If flexible bridges connect the push button to the trigger, then the push button can be articulated on the trigger, but excessive pressure can cause the bridges to yield, resulting in destruction of the diffuser
Solution Approach 1:
The patent extracts and eliminates the flexible bridges that connected the push button to the trigger. Instead, the push button is directly integrated with or rigidly connected to the trigger structure, removing the weak flexible connection points that could yield under excessive pressure while maintaining the articulated functionality.
4Device complexity
If the locking means are connected to the base only by the pivot axis, then the structure is simplified, but they are at risk of shifting to an undesired position with the smallest jolt
Solution Approach 1:
The patent merges the locking means with the trigger structure itself, making them integral parts rather than separate components connected only by a pivot axis. This integration provides inherent stability against jolts while maintaining structural simplicity, as the blocking function becomes part of the trigger's own structure rather than a separate articulated system.

AI summary
A trigger diffuser to be secured to the neck of a vial provided with an outlet valve (31) provides for securing it on the vial, actuating the valve (31), a trigger (200) movable between a neutral position, in which the valve is not actuated, and a diffusion position, in which an actuation element is moved in the direction of the valve so as to actuate it, and an outlet channel for the transport out of the diffuser of the product coming out of the valve. In order to store the diffuser without the risk of accidentally actuating the trigger even after the first withdrawal, the diffuser includes a blocking element (304) movable between a blocking position, in which the trigger (200) is prevented from reaching the diffusion position, and a release position, in which the trigger can be moved from the neutral position to the diffusion position.
