Facial Cleanser with Independent Pump Flow Control for Serum Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing at-home facial cleansing machines lack flow control, leading to inconsistent serum delivery, potential discomfort, and clogging issues, as they are either too abrasive or inadequate for frequent use.
Innovation Solution
An at-home facial hydrating and cleansing machine with independent flow control for serum and suction, featuring a liquid pump and button-activated valve to adjust serum flow, along with non-suction and full-suction tips for optimal serum-face contact and efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single pump is used to run the entire system, then the device complexity is reduced, but the flow control of serum is lost leading to inconsistent serum delivery
Solution Approach 1:
The system is divided into two independent pump systems: a liquid pump for serum delivery and an air pump for suction. This segmentation allows each pump to be controlled independently, enabling precise flow control of serum while maintaining the suction function, thereby resolving the contradiction between device complexity and serum delivery consistency.
Solution Approach 2:
A button-activated valve is introduced to dynamically control the serum flow rate. This allows the user to adjust the flow of serum independently from the suction, providing customizable treatment intensity and ensuring consistent serum delivery according to user preference without requiring a completely complex pump system.
2Quantity of substance
If serum flow is increased for better hydration, then the hydration effectiveness is improved, but the risk of clogging and dirt accumulation in tubing increases
Solution Approach 1:
The system incorporates a cleaning mode that periodically flushes the tubing with serum. By switching the tip to a full-suction cleaning tip and activating the liquid pump, the system creates a periodic cleaning action that prevents dirt and serum residue accumulation, allowing higher serum flow during treatment without compromising tubing reliability.
3Productivity
If suction strength is increased for better cleansing, then the cleansing effectiveness is improved, but the serum-face contact time is reduced causing dryness and discomfort
Solution Approach 1:
The system allows dynamic adjustment of both suction strength and serum flow rate through independent controls. Users can optimize the balance between suction power and serum delivery to maintain adequate serum-face contact time while achieving effective cleansing, preventing dryness and discomfort.
Solution Approach 2:
The system enables independent parameter adjustment of suction pressure and serum flow rate. By changing these parameters separately, the user can find the optimal combination that provides both strong cleansing action and sufficient serum contact time for hydration, resolving the contradiction between productivity and duration of action.
4Ease of operation
If the system is made gentle for frequent use, then the comfort and safety are improved, but the cleansing power is reduced
Solution Approach 1:
The system provides dynamic control over both suction strength and serum flow, allowing users to adjust the treatment to their comfort level. This enables frequent use at gentle settings while still providing effective cleansing when needed, as users can increase the parameters temporarily for stronger cleansing followed by gentler recovery treatments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables gentle and customizable facial treatments, preventing dryness or abrasiveness, allowing for frequent use while maintaining effective serum delivery and system cleanliness.
Implementation Method 1
the device is created with a liquid pump in addition to the traditional air pump in order to force liquid through the system independent of the vacuum rate of the waste
Implementation Method 2
a full-suction tip can be provided to prevent the discharge of any liquid other than into the waste container for maximum liquid-system contact and to allow localized suction therapy

AI summary
A method for cleansing a desired skin surface, and a device therefor, can include a base to house a jar for the cleansing liquid, a jar for the removed liquid and debris, a pump to deliver the cleansing liquid to a wand applicator, and a pump to suction the cleansing liquid and debris removed from the desired skin surface. The two pumps can be driven by separate motors to allow a user to separately control the amount of liquid dispensed and the magnitude of the suction force applied. The device can also include an infusion enhancer that assists in the opening of the pores of the desired skin surface or by tightening the desired skin surface. The device can further include a self-cleaning tip that allows a cleaning solution to be immediately recycled through the system into the jar for the removed liquid and debris.
