Micro Pump Vessel Merging Discharge Plate for Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional micro pump vessels for cosmetics have high manufacturing costs due to the large number of parts in the pump mechanism, and they often suffer from issues like volatile substances being blown out and the powder hardening when exposed.
Innovation Solution
A micro pump vessel design featuring a reduced number of parts, including an outer vessel, inner vessel, micro pump, discharge plate, discharge film, and ring-shaped fixing member, which allows for efficient cosmetic discharge when the outer lid is opened, utilizing a cylindrical rubber sealing cap, check valve, and piston-type member to minimize component count and enhance sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional pump mechanism is installed inside the compact, then cosmetic discharge function is achieved, but manufacturing cost increases due to large number of parts
Solution Approach 1:
The discharge plate and pump chamber are merged into a single integrated component. The discharge plate serves dual functions as both a sealing element and a pump chamber formation, eliminating the need for separate pump housing parts. This merging reduces the total part count and simplifies manufacturing assembly processes.
Solution Approach 2:
The discharge plate performs multiple functions simultaneously: it seals the pump chamber, forms the discharge opening, provides a surface for cosmetic accumulation, and acts as a structural support element. This multi-functionality eliminates the need for separate components for each function, reducing overall device complexity.
2Reliability
If the inner space of the compact is hermetically sealed, then volatile substance is prevented from being blown out, but manufacturing complexity increases
Solution Approach 1:
A flexible discharge film is used instead of rigid sealing components. The film can deform to maintain sealing contact while accommodating manufacturing tolerances and assembly variations. This flexible sealing approach achieves reliable volatile substance containment without requiring complex multi-component sealing structures.
Solution Approach 2:
The sealing function is merged into the discharge plate structure itself through integrated sealing surfaces and the flexible discharge film. Rather than adding separate sealing components, the sealing capability is built into the existing discharge plate design, maintaining reliability while reducing complexity.
3Ease of operation
If solid powder is used in the compact, then application is simple, but adhesion feeling deteriorates and powder is blown out during use
Solution Approach 1:
The cosmetic formulation is changed from solid powder to gel state by incorporating volatile substances. This parameter change in physical state transforms the cosmetic from a loose powder that blows out easily to a gel structure that adheres well to the skin while still providing simple application through the pump discharge mechanism.
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 design reduces manufacturing costs and prevents volatile substances from escaping while ensuring effective cosmetic discharge, maintaining the gel state's convenience and reducing the risk of hardening.
Implementation Method 1
a cylindrical spring 55 provided between the lower surface of the discharge plate 60 and the upper surface of the inner vessel lid 40
Implementation Method 2
a cylindrical rubber sealing cap 51 which is inserted into the first circumferential groove 62 of the discharge plate 60

AI summary
Provided is a pump for discharging cosmetics to the outside while simultaneously opening the outer vessel lid and pushing the discharge plate, which is formed of a smaller number of parts, and thus it is possible to reduce the manufacturing cost.
