Pressure-Sensitive Locking Dispenser Head Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers face issues with accidental removal of internal containers, misaligned parts, and complex structures that lead to malfunction and contamination, particularly in compressible designs with screw connections.
Innovation Solution
A dispenser with a detachable head featuring pressure-sensitive locking means and a collapsible container, where the head and body are made from polymer materials, ensuring correct alignment and secure locking through perpendicular linear paths for the locking parts, and incorporating a one-way valve for pressure equalization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connection is used between dispenser head and content container, then the connection can be securely fastened, but the internal container may be accidentally removed or parts may not be correctly aligned
Solution Approach 1:
The patent replaces the traditional screw connection (mechanical threading system) with a pressure-sensitive locking mechanism. The locking parts include pressure-sensitive elements that respond to applied pressure to engage or disengage the locking connection, eliminating the need for rotational screwing actions while maintaining secure attachment.
Solution Approach 2:
The pressure-sensitive locking mechanism is designed to automatically engage when the dispenser head is attached to the content container. The pressure-sensitive parts respond to the natural insertion pressure to trigger the locking action, eliminating the need for separate manual locking operations.
2Adaptability or versatility
If dispenser parts are positioned in open and close position, then the dispenser can be assembled and disassembled, but this increases the chances of malfunction and provides high risk of contamination
Solution Approach 1:
The patent replaces the open-close positioning mechanism with a pressure-sensitive locking system. Instead of requiring parts to be opened and closed for assembly/disassembly, the system uses pressure-sensitive locking parts that engage automatically upon attachment, reducing the number of mechanical steps and potential failure points.
3Stability of the object's composition
If rigid reservoir is used for liquid product, then the dispenser structure is stable, but the pump device has complex structure and cannot dispense smaller doses of liquid
Solution Approach 1:
The patent employs a flexible content container instead of a rigid reservoir. The container body is made of flexible material that can deform under pressure, allowing the liquid to be dispensed directly through pressure application without requiring a complex pump mechanism. This flexible membrane approach maintains structural stability while enabling precise dosing.
4Productivity
If current dispenser design is used, then the dispenser can dispense liquid, but it is not reusable and generates waste
Solution Approach 1:
The patent divides the dispenser system into separable components: a reusable dispenser head and replaceable content containers. The dispenser head contains the locking mechanism and can be reused, while the content containers are exchanged when empty. This segmentation allows the durable components to be reused multiple times, reducing overall material waste.
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 solution provides a reusable dispenser that prevents accidental removal, ensures correct alignment, reduces malfunction risk, and allows precise dosing with minimal contamination, enhancing user-friendliness and reliability.
Implementation Method 1
the pressure-sensitive locking means comprising opposed pressure-sensitive parts moveable by an applied pressure toward each-other in a first and second opposed direction aligned on a first linear path
Implementation Method 2
opposed locking parts being moveable by the pressure-sensitive parts, away from each other in a third and fourth opposed direction aligned on a second linear path, wherein the first linear path being substantially perpendicular to the second linear path
Implementation Method 3
The closed chamber may be pressurized by deforming at least one deformable area on the container body
Implementation Method 4
When the wall(s) of the container body is squeezed, a higher pressure is established in the chamber between the flexible content container and the container body
Implementation Method 5
The dispenser further comprises a one-way valve, preferably in the bottom of the container body. The valve may serve to equalize the pressure in the closed chamber around the collapsible content container
