Rotating Cosmetic Case Inner Body for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic cases are not optimized for storing a variety of cosmetic products with different shapes, leading to bulkiness and difficulty in handling multiple items while applying makeup on the go.
Innovation Solution
A compact cosmetic case design featuring rotating inner and outer components with retaining projections and stop elements, along with an axial applicator mechanism for secure storage and easy access to elongated products like lipstick and mascara, allowing for efficient storage and handling of various cosmetic items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional cosmetic cases with planar elongated housings are used to store multiple cosmetic products, then the case can contain a plurality of cosmetic products and articles, but the overall space occupied increases and portability decreases
Solution Approach 1:
The patent implements nesting by placing the inner rotatable body inside the outer housing, with the inner body containing multiple receptacles for cosmetic products. This nested structure allows multiple items to be stored in a compact arrangement, reducing the overall volume while maintaining storage capacity for multiple cosmetic products.
Solution Approach 2:
The patent transitions from a planar elongated housing to a three-dimensional cylindrical structure with rotatable inner body. This dimensional change allows cosmetic products to be arranged vertically and radially, maximizing space utilization and reducing the footprint of the cosmetic case while maintaining capacity for multiple products.
2Adaptability or versatility
If separate cosmetic cases are used for different types of cosmetic products (powder/paste vs. tubular items), then each product type can be stored appropriately, but the device complexity and number of items to carry increases
Solution Approach 1:
The patent creates a universal cosmetic case that can store multiple types of cosmetic products including powder, paste, and tubular items like lipstick and mascara. The rotatable inner body with multiple receptacles and the longitudinal receptacle provide versatile storage options for different product types, eliminating the need for separate specialized cases.
Solution Approach 2:
The patent merges previously separate storage functions into a single integrated case. The outer housing contains both the rotatable inner body (for powder/paste products) and the longitudinal receptacle (for tubular items), combining multiple storage purposes into one unified device that reduces the total number of cosmetic cases needed.
3Adaptability or versatility
If multiple loose cosmetic items are carried in a handbag, then all necessary cosmetic products are available, but handling difficulty increases when applying makeup on the go
Solution Approach 1:
The patent prepares cosmetic products for easy access by pre-organizing them in fixed receptacles within the rotatable inner body and longitudinal receptacle. The stop elements pre-position the inner body at specific angular positions, allowing users to quickly locate and access needed products without searching through loose items in a handbag.
Solution Approach 2:
The patent incorporates a rotatable inner body that can be dynamically rotated to bring different receptacles into accessible positions. This dynamic element, controlled by stop elements, allows users to easily access different cosmetic products by simply rotating the inner body, significantly improving handling ease during makeup application compared to static loose items.
