Solution Overview

Problem

Existing micro pump vessels for cosmetics have high manufacturing costs due to a large number of parts and do not completely exhaust cosmetic contents, leading to waste.

Innovation Solution

A micro pump vessel design with a reduced number of parts, featuring a button-activated outer lid, a micro pump, a discharge plate, a discharge film, and dual pistons that ensure complete exhaustion of cosmetic contents by lowering to vacuum the inner vessel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large number of parts are used to constitute the pump inside the micro pump vessel, then the pump function is improved, but the manufacturing cost increases

Engineering Contradiction:
Improvepump functionVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines multiple pump components into a more integrated structure. The pump chamber integrates the pump body, pump chamber, and related components into a unified structure that reduces the total number of separate parts while maintaining the pumping function. This merging approach directly addresses the contradiction by reducing part count (lowering manufacturing cost) while preserving the essential pump operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The discharge plate serves multiple functions: it acts as a seal for the pump chamber, provides a surface for cosmetic discharge, and works with the puff to enable product application. By making components multi-functional, the patent reduces the need for separate dedicated parts, thereby lowering manufacturing cost while maintaining reliable pump function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If no member is provided to sweep down the cosmetic contents, then the device structure is simplified, but the cosmetic contents are not completely exhausted

Engineering Contradiction:
Improvedevice structureVSAvoidcosmetic contents
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The pump mechanism itself is designed to automatically sweep down and exhaust the cosmetic contents without requiring a separate sweeping member. The pump chamber and discharge plate work together to create a self-cleaning action that pushes remaining cosmetics toward the discharge opening, ensuring complete exhaustion while keeping the device structure simple.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The discharge plate is designed to move or interact dynamically with the cosmetic contents during the pumping cycle. This dynamic interaction creates a sweeping effect that pushes remaining products toward the discharge holes, ensuring complete exhaustion without adding a separate static sweeping component.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the inner space of the compact is hermetically sealed, then the volatile substance is protected from being blown out, but the manufacturing complexity increases

Engineering Contradiction:
Improvehermetic sealingVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing function is integrated into the existing pump chamber and discharge plate structures rather than being a separate component. The pump chamber itself serves as the hermetic barrier, and the discharge plate provides sealing at the discharge interface. This integration reduces manufacturing complexity while maintaining reliable hermetic sealing to protect volatile substances.

Inventive Principle:
Principle #5Merging (Combining)

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 ensures all cosmetic contents are used by employing a button-activated mechanism and dual pistons that lower to exhaust the contents, preventing leftover residue.

AI summary

A micro pump vessel has an outer vessel on one side of which a button is formed and an outer vessel lid which is hinge-coupled to one side of the outer vessel to be opened and closed. In the vessel, a first and a second pistons are installed on an upper surface of cosmetic contents, and thus, when the cosmetic contents are pumped and used by the operation of a micro pump, the first and the second pistons lower to exhaust all the cosmetic contents so as not to discard the remaining cosmetic contents.
