Button-Sliding Cosmetic Pump Prevents Lid Contamination

Solution Overview

Problem

Existing liquid instruments with pump-type discharging structures face issues such as inconvenient lid operation, potential mishandling or loss of the lid, and contamination due to contents being discharged over the lid, leading to spoilage and contamination.

Innovation Solution

A button sliding type open and close apparatus for liquid instruments, featuring a shoulder, vertically movable button body, and a sliding button that opens and closes a contents pumping hole without separating the lid, utilizing a guide cap and sliding limitation hole to control the button's movement and prevent excessive sliding, allowing for efficient discharging without compressing the nozzle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate lid is provided to cover the nozzle, then the contents are protected from contamination, but the lid operation becomes inconvenient and the lid may be mishandled or lost

Engineering Contradiction:

Improveprotection from contaminationVSAvoidlid operation convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The lid and pump button are merged into a single integrated component. The button structure incorporates both the lid covering function and the pump operation function, eliminating the need for a separate lid. When the button is pushed, it simultaneously opens the nozzle for dispensing and maintains coverage protection when not in use.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The button serves multiple functions: it acts as both the lid/cover for the nozzle and the pump mechanism for dispensing contents. This multi-functional design eliminates the separate lid while maintaining protection capabilities and improving operational convenience.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If the lid is opened by rotating it, then the nozzle can be exposed, but the lid has to be rotated several times and may be mishandled or lost

Engineering Contradiction:

Improvenozzle exposureVSAvoidrotation time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The lid and pump button are merged into a single integrated component. The button structure incorporates both the lid covering function and the pump operation function, eliminating the need for a separate lid. When the button is pushed, it simultaneously opens the nozzle for dispensing and maintains coverage protection when not in use.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

Instead of rotating the lid to open it (conventional approach), the invention inverts the operation by pushing the button linearly to achieve both lid opening and pump activation. This reverses the traditional rotational opening mechanism into a linear push action.

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If the nozzle is exposed over the lid for dispensing, then the contents can be discharged, but the contents may be discharged over the lid and contaminate the surroundings

Engineering Contradiction:

Improvedispensing efficiencyVSAvoidcontamination

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The lid and pump button are merged into a single integrated component. The button structure incorporates both the lid covering function and the pump operation function, eliminating the need for a separate lid. When the button is pushed, it simultaneously opens the nozzle for dispensing and maintains coverage protection when not in use.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated button acts as an intermediary structure that guides the dispensing contents directly away from the lid area. The button's design creates a controlled dispensing path that prevents contents from contacting the lid or surrounding surfaces.

Inventive Principle:

Principle #24Intermediary (Mediator)
