Solution Overview

Problem

Cosmetics packaging is complex, leading to increased production costs, labor, and environmental impact due to the need for multiple components, which complicates assembly, quality control, and recycling.

Innovation Solution

A case design with a housing and a rotatable cover that moves between retracted and extended states using a thread and guide mechanism, reducing the number of parts to two and allowing for easy assembly and operation, while maintaining protection and accessibility of the applicable material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple components are used in cosmetics packaging, then protection and functionality are improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
ImproveprotectionVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple packaging components into a single integrated case structure. The housing, receptacle, and cover form a unified protective enclosure that maintains all necessary functions (protection, support, accessibility) while eliminating the need for separate tube, cap, and base components. This merging directly resolves the contradiction by reducing component count while preserving protective functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single case structure performs multiple functions simultaneously: the housing provides structural protection, the receptacle supports and positions the cosmetic material, and the cover enables controlled accessibility. This multi-functional design eliminates the need for specialized components for each function, thereby reducing overall device complexity while maintaining comprehensive protection.

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

2Adaptability or versatility

If multiple components are used in cosmetics packaging, then functionality is improved, but assembly complexity and labor cost increase

Engineering Contradiction:
ImprovefunctionalityVSAvoidassembly process
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By merging the housing, receptacle, and cover into a single integrated case, the patent eliminates multiple assembly steps. The case can be manufactured as one piece or pre-assembled units requiring minimal final assembly, directly addressing the contradiction by simplifying the assembly process while maintaining versatile functionality through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

While the case is integrated, it is functionally segmented into distinct zones: the housing for protection, the receptacle for material support, and the cover for accessibility control. This functional segmentation allows the single component to perform multiple functions without requiring physical assembly of separate parts, thereby simplifying manufacture while preserving functionality.

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple components are used in cosmetics packaging, then protection is improved, but quality control difficulty increases

Engineering Contradiction:
ImproveprotectionVSAvoidquality control
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The integrated case design eliminates interfaces between multiple components where defects could occur. With fewer joints, connections, and mating surfaces, there are fewer potential failure points and quality issues to detect and control. The single-structure design directly reduces quality control difficulty while maintaining protective reliability.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If multiple components are used in cosmetics packaging, then functionality is improved, but environmental impact increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidmaterial waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The patent consolidates multiple packaging components into a single case structure, directly reducing the total amount of material required. Fewer components mean less material consumption during manufacturing and less waste generation. The integrated design maintains full functionality while minimizing material use, directly addressing the environmental concern.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The simplified single-component case is easier to recycle or dispose of compared to multi-component packaging. The reduced complexity of material composition and structure facilitates recovery and recycling processes, thereby reducing environmental impact while preserving the functional capabilities needed for product protection and accessibility.

Inventive Principle:
Principle #34Discarding and recovering
