Solution Overview

Problem

Existing storage solutions for makeup tools, such as makeup brushes and cotton pads, do not effectively address the issue of bacterial growth due to inadequate drying, leading to inconvenience and potential health hazards.

Innovation Solution

A storage box with a heating function that includes a cover with aligned holes and notches for securing brushes, a heating module with a temperature controller, and a fan for airflow, allowing for automated drying of makeup tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If makeup brushes are stored without drying, then storage convenience is improved, but bacterial growth occurs due to moisture

Engineering Contradiction:

Improvestorage convenienceVSAvoidbacterial growth

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent combines storage and drying functions into a single integrated device. The storage box includes a heating module and fan that actively dry makeup brushes while they are stored, eliminating the need for separate drying steps and preventing bacterial growth through continuous moisture removal.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces passive air drying with an active mechanical drying system consisting of a heating module and fan. This mechanical system forces air circulation and heating within the storage box, effectively removing moisture from makeup brushes that would otherwise remain damp and prone to bacterial growth.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Use of energy by moving object

If air drying is used for makeup brushes, then energy consumption is reduced, but drying time increases and productivity decreases

Engineering Contradiction:

Improveenergy consumptionVSAvoiddrying efficiency

Core Design Contradiction:

Use of energy by moving objectVSProductivity

Solution Approach 1:

The patent changes the physical parameters of the drying environment by introducing controlled heating and forced air circulation. The heating module raises the temperature within the storage box, while the fan increases air flow velocity, both of which accelerate the evaporation rate and reduce drying time significantly compared to passive air drying.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The drying function operates continuously whenever the storage box is in use, rather than requiring a separate dedicated drying period. The heating module and fan run concurrently with storage, maintaining constant moisture removal activity and eliminating idle waiting time associated with traditional air drying methods.

Inventive Principle:

Principle #20Continuity of useful action

3Productivity

If a heating function is added to the storage box, then drying efficiency is improved, but device complexity increases

Engineering Contradiction:

Improvedrying efficiencyVSAvoidstructure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The storage box is designed to perform multiple functions: storage, heating, and forced air circulation. By integrating the heating module and fan into the existing storage structure, the device achieves multi-functionality without requiring completely separate systems, thereby managing complexity while delivering effective drying performance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The heating module and fan are nested within the storage box structure, with components arranged to fit within the available internal space. The heating element is positioned to maximize heat distribution, and the fan is integrated into the wall structure, creating a compact nested arrangement that minimizes overall device complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

The present invention relates to a storage box with a heating function in the field of cosmetics technology. It consists of a cover and a main body. The cover comprises a pressure plate, a silicone film, and a shell. The silicone film is squeezed and installed on the top of the shell through the plate. There are several round holes on the pressure plate, and a number of notches in the silicone film. This storage box with heating function allows makeup brushes to be inserted into corresponding circular holes of suitable diameters. The cross-shaped notches secure the brush heads, suspending them inside the cover. By activating the switch button and using the display screen and rotation buttons to select the drying time, the drying program starts automatically. It conveniently dries makeup brushes and cotton balls, eliminating the need to wait for air drying.
