Solution Overview
Problem
Existing body care devices face issues with automatic product application during treatment, leading to clogging and contamination, and struggle with precise control of product quantity and user comfort.
Innovation Solution
A body care accessory with a treatment head and a pump system that automatically dispenses cosmetic or medicinal products using a nozzle, where the pump is operated by the movement of the treatment tool, ensuring controlled product delivery and reducing clogging and contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the roller is used for both massage and cosmetic product application, then automatic product application is achieved, but the roller clogs rapidly
Solution Approach 1:
The device is divided into separate functional components: a dedicated applicator roller for cosmetic product application and separate massage rollers for mechanical massage. This segmentation allows each component to perform its specific function without interfering with the other, preventing the clogging issue that occurs when a single roller must perform both functions simultaneously.
Solution Approach 2:
The cosmetic product application function is extracted from the massage function. The applicator roller is positioned separately from the massage rollers, with its own dedicated product reservoir. This extraction ensures that the massage rollers remain clean and functional while the applicator roller handles product dispensing without contamination from massage contact.
2Ease of operation
If the applicator roller contacts the skin during massage, then product is applied, but contamination and pollution of the product occurs
Solution Approach 1:
The applicator roller is segmented as a separate component from the massage rollers. It has its own dedicated product reservoir and dispensing mechanism, physically isolated from the massage contact surfaces. This segmentation prevents skin contaminants from the massage area from polluting the cosmetic product reservoir.
Solution Approach 2:
The applicator roller acts as an intermediary between the product reservoir and the skin, rather than allowing direct contact between the product reservoir and skin contaminants. The separate positioning and dedicated product delivery system serve as a protective barrier, preventing contamination while still enabling product application during treatment.
3Ease of operation
If a pressurized reservoir is used for product dispensing, then product can be applied during massage, but the amount of product is difficult to control
Solution Approach 1:
The pump mechanism provides feedback-based control of product dispensing. As the applicator roller rotates and contacts the skin, the pump mechanism responds to the mechanical input from roller rotation to meter and control the amount of product dispensed. This creates a feedback loop where the treatment movement itself regulates product delivery, ensuring precise quantity control while maintaining ease of operation during massage.
Solution Approach 2:
The system uses the mechanical energy from the treatment tool's own movement to operate the pump mechanism that controls product dispensing. The rotation of the applicator roller during massage automatically activates the pump, which meters and dispenses the appropriate amount of product without requiring separate control mechanisms. The system serves itself by using its operational movement to regulate product delivery.
4Ease of operation
If high pressure is used to open the dispensing valve, then product can be dispensed from pressurized reservoir, but user comfort is reduced
Solution Approach 1:
The high-pressure mechanical valve opening system is replaced with a pump mechanism that uses controlled mechanical input from the treatment tool's rotation. Instead of relying on high pressure to force the valve open, the pump mechanism uses the rotational movement to meter and deliver product at controlled, comfortable pressures. This substitution eliminates the need for high-pressure systems while maintaining effective product dispensing.
Solution Approach 2:
The pressure parameter is changed from high, uncontrolled pressure in the pressurized reservoir system to low, controlled pressure delivered by the pump mechanism. The pump converts the rotational mechanical energy into controlled product delivery at pressures suitable for user comfort, while still achieving effective product dispensing during the massage treatment.
