Applicator Head Structure with Elastic Jaw Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional makeup pens with brush applicators have a complex structure, leading to instability and unsatisfactory usage due to an unreasonable assembling structure and discharging core strip component.
Innovation Solution
A head structure for the applicator comprising a hollow sleeve, an applying head with a through hole, a clamp with elastic jaws, and a fixing base, where the applying head is made of soft rubber and plastic, allowing for even application and easy assembly/disassembly, preventing cosmetic material absorption and waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional brush structure is used in makeup pens, then the applicator can apply cosmetic material, but the structure becomes complicated and stability deteriorates
Solution Approach 1:
The patent extracts the discharging core strip component from the traditional brush structure and replaces it with a simplified applying head that has a through hole for direct cosmetic discharge. This removes the complicated internal structure while maintaining the application function, directly resolving the contradiction between operational effectiveness and structural complexity.
Solution Approach 2:
The applying head is divided into distinct functional segments: the head portion with through hole for cosmetic discharge, the annular tail for clamping, and the fluff layer for application. This segmentation allows each part to perform its specific function efficiently while keeping the overall structure simple and stable.
2Ease of operation
If a conventional brush structure is used, then cosmetic material can be applied, but the assembling structure becomes unreasonable and usage stability deteriorates
Solution Approach 1:
The patent merges the clamping function and the applying head function into a single integrated component. The applying head serves both as the cosmetic discharge structure (with through hole) and as the element to be clamped by the elastic jaws, eliminating the need for separate discharging core strip components and improving assembly rationality and stability.
Solution Approach 2:
The elastic jaws automatically clamp the annular tail of the applying head when assembled, providing self-fixing functionality. This self-service mechanism ensures stable usage without requiring complex assembly structures or additional fastening components.
3Productivity
If the applying head is made of soft rubber and plastic material, then cosmetic material is not absorbed and application is even, but the structure requires secure fixing to prevent falling off
Solution Approach 1:
The patent uses elastic jaws that can dynamically adjust their clamping force. The elastic material allows the jaws to flex during assembly and then maintain a constant clamping force on the annular tail, securely fixing the applying head without requiring complex mechanical fastening structures. This dynamic elasticity resolves the contradiction between simple fixing structure and reliable fixation.
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 solution provides a simple, stable, and reusable applicator head that ensures even cosmetic application, reduces waste, and offers a softer touch with fluff implantation, while being securely fixed to prevent falling off.
Implementation Method 1
the clamp includes a bottom and at least one pair of symmetrical and elastic jaws connected to the bottom, the annular tail is placed between the jaws, the jaws can tightly fix the applying head
Implementation Method 2
When a surface of the applying head is implanted with the fluff, the touch feeling of the applying head is softer. Moreover, since the fluff has an adsorption capacity, the applying effect is more exquisite
