Dispensing Package Elevator Platform Screw Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer care product packages, such as those for antiperspirant and deodorant, often have empty spaces formed during filling, requiring multiple actuations to dispense the first dose due to air bubbles and product volume changes, leading to inefficiencies in dispensing the initial product quantity.
Innovation Solution
A dispensing package with a movable elevator platform and screw assembly featuring external and internal threads of varying pitches, allowing the platform to be displaced upward efficiently to overcome empty spaces and facilitate quicker initial product dispensing while maintaining accurate dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the dispensing package is filled from above, then the filling process is simple, but an empty space is formed in the upper part of the dispensing package
Solution Approach 1:
The elevator platform is positioned in advance to bridge the empty space formed during filling, ensuring that the product can be dispensed immediately without requiring multiple actuations to overcome the air gap
2Adaptability or versatility
If the empty space is large, then the package design is flexible, but the operating button has to be repeatedly operated several times before the first dose is delivered
Solution Approach 1:
The elevator platform acts as an intermediary mechanism that automatically fills the empty space by moving upward when the screw assembly is actuated, eliminating the need for repeated manual operations to deliver the first dose
3Productivity
If the elevator platform is moved upward to overcome empty space, then the first dose is delivered quickly, but the dosing precision may be compromised
Solution Approach 1:
The screw assembly features two distinct thread portions with different pitches: a first thread portion for rapid initial movement to overcome empty space, and a second thread portion for precise dosing control, allowing the system to segment the dispensing action into speed and precision phases
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 simplifies the actuation process for the first dose of consumer care products by overcoming empty spaces within the package, reducing the number of turns required to dispense the product and ensuring precise dosing without compromising the dispensing efficiency.
Implementation Method 1
a screw assembly 330; and a movable elevator platform 320; wherein the screw assembly 330 comprises a screw base disposed adjacent to the first end 260 and rotatably associated with the one or more jackets (200, 110); a spindle 332 that supports external threads 333
Implementation Method 2
The spindle 332 comprises a first external thread portion 335 having a first pitch P1; and a second external thread portion 337 having a second pitch P2; wherein the second pitch P2 is larger than the first pitch P1
