Replaceable Serum Head with Vibratory Motor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic devices that dispense serum and provide a massaging effect are often complex in construction, require disposal of the entire device when the serum runs out, and generate environmental waste due to electronic components, whereas users desire a simpler, more sustainable solution for serum application and massage.
Innovation Solution
A device with a separable housing and head assembly, where the head assembly is easily replaceable and refillable, utilizing a vibratory mechanism to dispense serum through a ball that contacts the skin, minimizing waste and allowing for interchangeable serum types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a powered massaging device with electronic components is used, then a massaging effect is provided, but the entire device must be disposed of when serum runs out, generating electronic waste
Solution Approach 1:
The device is divided into two separate assemblies: a reusable housing assembly containing the powered vibratory mechanism and electronic components, and a disposable head assembly containing the serum reservoir. This segmentation allows the electronic components to be reused while only the serum-containing head is disposed of, eliminating electronic waste while maintaining the massaging effect.
2Ease of operation
If a complex massaging device with rotating brushes and electric pump is used, then serum can be dispensed at controllable intervals, but the device construction becomes complex
Solution Approach 1:
The device uses the natural motion of the user's hand rolling the ball over the skin to dispense serum, eliminating the need for complex electric pumps and control mechanisms. The vibratory motor simply provides massage and enhances serum distribution, while the user's own motion controls the dispensing rate.
3Device complexity
If the entire device is disposed of when serum runs out, then simplicity of design is maintained, but environmental waste increases due to electronic components
Solution Approach 1:
The device is divided into a reusable housing assembly with electronic components and a disposable head assembly with the serum reservoir. This allows the complex electronic parts to be reused multiple times while only the simple plastic head containing serum is disposed of, reducing environmental waste while maintaining design simplicity in each component.
4Device complexity
If a hand-driven twisting mechanism is used for lotion dispensing, then no power drive is needed, but a separate massager must be located at the opposite end
Solution Approach 1:
The device merges the lotion dispensing function and massaging function into a single integrated ball mechanism. The vibratory motor provides massaging action at the same location where serum is dispensed through the ball, eliminating the need for separate massaging components at the opposite end of the device.
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
The device provides an effective, environmentally friendly, and cost-effective means to apply serum and massage the skin, reducing electronic waste and enabling easy replacement and refilling of serum reservoirs, while maintaining a simple and ergonomic design.
Implementation Method 1
The device comprises a housing assembly which is to be hand held and a head assembly. A vibratory motor is mounted in the housing and causes the head assembly to vibrate to execute a massage effect.
Implementation Method 2
A ball is rotatably retained in the head assembly and is contactable with the skin of a user. A portion of the ball is in fluid communication with the serum reservoir.
