Multi-Color Press-Type Cosmetic Pen with Independent Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single-color lip pens are inconvenient and costly for users as they require multiple pens in different colors, leading to increased storage and preparation burdens.
Innovation Solution
A multi-color press-type cosmetic pen with at least two actuating mechanisms at the tail end, each comprising a button, ratchet, ratchet wheel, screw rod, nut, piston, and spring, allowing for the separate discharge of different color materials by pressing distinct buttons, integrated into a cylindrical pen body with multiple liquid material receiving cavities and discharge holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users prepare multiple single-color lip pens to achieve multi-color makeup, then color variety is improved, but storage space requirement and preparation complexity increase
Solution Approach 1:
The patent combines multiple color materials and their corresponding actuating mechanisms into a single pen body. The pen body contains multiple cavities, each storing a different color material, with each cavity having its own actuating mechanism. This merging allows users to access multiple colors from one pen rather than managing multiple separate pens.
Solution Approach 2:
The pen is designed to perform multiple functions by integrating different color materials and discharge mechanisms into a single device. Each actuating mechanism can independently control the discharge of different color materials, making the single pen universal for various makeup color needs.
2Adaptability or versatility
If multiple single-color lip pens are prepared for different colors, then color selection is improved, but expense increases
Solution Approach 1:
The patent combines multiple color materials and their corresponding actuating mechanisms into a single pen body. The pen body contains multiple cavities, each storing a different color material, with each cavity having its own actuating mechanism. This merging allows users to access multiple colors from one pen rather than managing multiple separate pens.
3Ease of operation
If single-color lip pens are used, then device simplicity is maintained, but functional versatility deteriorates
Solution Approach 1:
The pen body is segmented into multiple independent cavities, each containing a different color material and associated actuating mechanism. This segmentation allows each color to be independently controlled while maintaining the overall simplicity of a single pen device. Users can operate each cavity independently through its own button, ratchet, and piston system.
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 the user to switch between and mix different colors using a single pen, reducing the need for multiple pens and enhancing convenience by integrating multiple colors and functions into a single device.
Implementation Method 1
a spring (9) arranged in the actuating mechanism
Implementation Method 2
The screw rod (6) is inserted in the ratchet wheel (5), and the outer wall of the screw rod (6) is provided with a circular external thread. The nut (7) is fixed on the pen body (1), and the inner wall of the nut (7) is provided with a circular internal thread. The upper end of the screw rod (6) is exposed outside the ratchet wheel (5), so that the circular external thread of the screw rod (6) is engaged with the circular internal thread of the nut (7).
Implementation Method 3
Each of the ratchet (4) and the ratchet wheel (5) is hollow and cylindrical. The ratchet wheel (5) is inserted into the ratchet (4). At least one inclined surface (51) is provided on the outer peripheral wall of the ratchet wheel (5), and an abutting portion matched with the inclined surface (51) is provided on the inner peripheral wall of the ratchet (4).
