Solution Overview

Problem

Conventional skin care devices face issues with solution leakage and inefficient skin cleansing due to poor adherence to curved skin surfaces and short contact time of the skin care solution, leading to suboptimal skin care efficiency and waste removal.

Innovation Solution

A tip for a skin care device handpiece featuring a tip housing with an inclined contact end, a separation wall with spray and suction ports, and zigzag flow path partitions that guide the solution in a zigzag flow from spray ports to suction ports, ensuring close contact with the skin and maximizing contact time and area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional tip design is used, then the structure is simple, but the tip cannot adhere closely to curved skin surfaces causing solution leakage

Engineering Contradiction:
Improvesolution leakage preventionVSAvoidtip structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The tip is segmented into multiple functional components: a tip housing, a separation wall dividing the interior into spray and suction chambers, and multiple flow path partitions creating zigzag channels. This segmentation allows each component to perform its specific function while collectively achieving close skin adherence and preventing solution leakage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flow path partitions create a three-dimensional zigzag flow path within the tip structure, transforming the simple linear flow into a multi-dimensional path that extends contact time and ensures thorough skin treatment while maintaining close adherence.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If the tip contacts the skin briefly, then the operation is fast, but the skin care solution contact time is insufficient reducing skin care efficiency

Engineering Contradiction:
Improveskin care efficiencyVSAvoidsolution contact time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The zigzag flow path partitions ensure continuous contact between the skin care solution and the skin surface throughout the treatment area. The solution flows continuously through multiple partitions in a zigzag pattern, maintaining constant useful action rather than brief intermittent contact, thereby improving skin care efficiency.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The flow path partitions are arranged to create a dynamic zigzag flow pattern that adapts to the skin surface contours. This dynamic flow path ensures the solution continuously engages with the skin across varying surfaces, maximizing contact time without requiring prolonged treatment duration.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If spray ports are positioned far from suction ports, then coverage area is larger, but solution contact time with skin is reduced

Engineering Contradiction:
Improvespray coverage areaVSAvoidsolution contact time
Core Design Contradiction:
Area of stationary objectVSDuration of action of moving object

Solution Approach 1:

The flow path partitions create a curved zigzag path between spray and suction ports, forcing the solution to follow a prolonged curved trajectory across the skin surface. This curved path geometry extends the contact time despite the spatial distance between spray and suction ports, while still covering a large treatment area.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The solution flow is transformed from a direct linear path to a multi-dimensional zigzag path through the partitions. This dimensional change in flow trajectory allows the solution to traverse a longer effective path length within the available space, increasing contact time while maintaining broad coverage area.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A skin care device comprising a tip is proposed. The tip may include a tip housing, a separation wall, and flow path partitions. The tip housing has a first side engaged with a handpiece of the skin care device, and a second side having a contact end inclined inward to contact a skin. The separation wall may be perpendicular to an inner peripheral surface of the second side of the tip housing, and may include spray ports for spraying a skin care solution and a suction port for sucking the sprayed skin care solution together with skin waste. The flow path partitions may be perpendicular to an outer surface of the separation wall, forming a flow path in a zigzag form from the spray ports toward the suction port. The flow path partitions may be concave with a center of the tip housing as a lowest point.
