Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional cosmetic containers are inconvenient as they require users to open multiple lids to check the contents, and the push button on the lid obstructs visibility and occupies space, leading to potential damage and instability.

Innovation Solution

A cosmetic container design featuring a transparent container body and lid with a push button installed inside the lid using a button coupling member, allowing the contents to be visible without opening the lid and ensuring the push button is stable and securely fixed, preventing it from shaking during use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a push button is installed on the front of the outer container, then the container can be opened and closed, but the push button blocks visibility and occupies space inside the container

Engineering Contradiction:

Improveopening and closing operationVSAvoidvisibility of cosmetic material

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The push button is extracted from the front surface of the container lid and repositioned to the rear surface. This relocation removes the obstruction caused by the button on the front transparent surface, allowing full visibility of the cosmetic material while maintaining the opening and closing function through the button's interaction with the locking hook mechanism.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If a push button is installed on the container lid, then the container can be opened and closed, but the button may be separated or damaged by external impact

Engineering Contradiction:

Improveopening and closing operationVSAvoidstability of push button

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The push button is nested within a button receiving groove formed in the container lid, creating a recessed mounting structure. This nested configuration protects the push button from external impacts by surrounding it with the lid material, while still allowing the button to functionally interact with the locking hook through the lid structure.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The button coupling member is integrated directly into the container lid structure, merging the button mounting function with the lid itself. This integration eliminates separate mounting components and creates a unified structure where the lid provides both the mounting substrate and protective enclosure for the push button mechanism.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If a push button is installed on the container lid, then the container can be opened and closed, but the button occupies predetermined space inside the container

Engineering Contradiction:

Improveopening and closing operationVSAvoidstorage space for cosmetics

Core Design Contradiction:

Ease of operationVSVolume of stationary object

Solution Approach 1:

The push button mechanism is extracted from the interior space of the container and repositioned to the exterior rear surface of the lid. This extraction eliminates the volume occupation problem by locating all button-related components outside the cosmetic storage volume, maximizing the available space for cosmetics while preserving the opening and closing functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

4Loss of information

If the container lid and refill container are opened to check contents, then the type and color of cosmetic material can be checked, but it is inconvenient to use

Engineering Contradiction:

Improveinformation about cosmetic materialVSAvoidconvenience of checking contents

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The push button is extracted from the front viewing surface and relocated to the rear surface of the lid. This extraction allows the entire front surface of the transparent lid to remain unobstructed, providing clear visibility of the cosmetic material type and color without requiring the user to open either the outer container or refill container, thereby improving convenience.

Inventive Principle:

Principle #2Taking out (Extraction)
