Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable beauty instruments are limited in their ability to effectively treat both large areas of flat skin and small, edge areas, resulting in undiversified working modes and difficulty in stimulating biological parts like the ala nasi.
Innovation Solution
A portable beauty instrument with a housing design that includes electrodes in both the end and side portions, allowing for the formation of electrode pairs to generate microcurrents, which can be adjusted to treat both large and small skin areas, including hard-to-reach areas like the ala nasi, by tilting the instrument.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the beauty instrument uses a conventional single-electrode configuration, then it can process large areas of flat skin, but it cannot effectively treat small edge areas like the ala nasi
Solution Approach 1:
The electrode system is segmented into multiple independent electrodes (first electrode, second electrode, third electrode) positioned at different locations on the housing. This segmentation allows different electrode combinations to be activated for different treatment scenarios - large area treatment using first and second electrodes, or localized treatment using third electrode with adjacent first electrode, thereby resolving the contradiction between coverage area and adaptability
Solution Approach 2:
The beauty instrument is designed with multi-functional electrode pairs that can serve different purposes. The first electrode serves dual purposes: as part of a large-area electrode pair (with second electrode) for flat skin treatment, and as a localized electrode (with third electrode) for edge area treatment. This universality allows one device to perform multiple treatment functions, resolving the contradiction between area coverage and working mode diversity
2Quantity of substance
If the beauty instrument discharges current to a large skin area, then it improves overall skin condition, but it causes irrelevant stimulation of surrounding skin when treating local areas
Solution Approach 1:
Different electrode pairs are designed with different spatial configurations and activation patterns. When treating edge areas like the ala nasi, only the third electrode and adjacent first electrode are activated, creating a localized current path that concentrates stimulation precisely where needed. This local quality approach ensures that increased electrode quantity does not lead to irrelevant stimulation of surrounding skin areas
3Device complexity
If the beauty instrument uses fixed electrode positions, then the structure is simple, but it cannot adapt to different facial contours and hard-to-reach areas
Solution Approach 1:
The electrode system incorporates dynamic switching capability between different electrode pairs through control circuitry. The system can dynamically select which electrodes to activate based on the treatment area and facial contour being addressed. This dynamic configuration allows the instrument to adapt to different facial geometries and hard-to-reach areas without increasing physical structural complexity
