Skin Care Device with Segmented Accommodating Portion for Viscosity Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult for individuals to apply skin care materials with varying viscosities, such as high viscosity lotions and low viscosity liquids, to their own back portions without assistance, as existing products are not designed to effectively handle both types efficiently.
Innovation Solution
A skin care device with a handle and detachable massage member featuring an accommodating portion with through holes and partition walls, allowing for the application and massage of both high and low viscosity materials, including a brush member option for different care functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a long stick is used to apply high viscosity skin care material on the back, then the application reach is improved, but the low viscosity skin care material cannot be applied effectively because it flows down
Solution Approach 1:
The accommodating portion is divided into multiple accommodating spaces by partition walls, with each space designed to hold different amounts of skin care material. This segmentation allows the device to effectively handle both high viscosity materials (using larger spaces) and low viscosity materials (using smaller spaces with better containment), resolving the contradiction between application reach and adaptability to different viscosities.
Solution Approach 2:
Different accommodating spaces are designed with different capacities and configurations to match different skin care material viscosities. The partition walls create localized regions with specific characteristics (size, shape, containment level) that are optimized for particular viscosity ranges, allowing the single device to adapt to various material types while maintaining long reach capability.
2Adaptability or versatility
If various skin care products for back portion are purchased individually, then the functionality for different materials is improved, but the device complexity and storage requirements increase
Solution Approach 1:
The skin care device is designed as a universal tool that can handle both high viscosity materials (lotions, creams) and low viscosity materials (oils, milks, diluted solutions) through its multi-compartment accommodating portion. The detachable massage members and adjustable partition walls enable a single device to perform multiple functions that would otherwise require separate products, reducing device complexity and storage needs while maintaining versatility.
Solution Approach 2:
The invention merges the functionality of multiple separate skin care products into a single integrated device. By combining the accommodating portion with multiple spaces, partition walls, and detachable massage members, the device consolidates what would otherwise require multiple individual products, thereby reducing overall complexity while preserving adaptability to different material viscosities.
3Ease of operation
If partition walls divide the accommodating space into multiple spaces, then the control over skin care material discharge is improved, but the device structure becomes more complex
Solution Approach 1:
The accommodating portion is segmented into multiple accommodating spaces by partition walls, allowing independent control over the discharge of different skin care materials. This segmentation provides ease of operation by enabling selective filling and discharge control for each space, while the modular nature of the partition walls keeps the added structural complexity manageable and justifiable by the operational benefits.
