Cosmetic Brushing Device Merging Clipping and Blocking Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid lip cosmetics containers have complex structures, leading to increased time, labor, and cost in manufacturing and assembly.
Innovation Solution
A brushing device with a simple structure comprising an applying component and a clipping component, where the applying component has a passage for liquid cosmetics and the clipping component is compressible to block the passage using a cap, reducing the number of components and assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structure with multiple components (blocking member, floating plug, connecting sleeve) is used to prevent liquid flow, then the sealing reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the blocking member, floating plug, and connecting sleeve into a single integrated clipping component. This clipping component has a body portion that clips onto the container opening and a blocking portion that directly blocks the passage, eliminating the need for multiple separate components while maintaining the sealing function.
Solution Approach 2:
The clipping component serves multiple functions simultaneously: it acts as both a fastening mechanism (clipping onto the container opening) and a blocking mechanism (blocking the passage with its blocking portion). This multi-functionality reduces the overall component count while maintaining reliability.
2Ease of operation
If multiple components (blocking member, floating plug, connecting sleeve, cap) are assembled to form the brushing device, then the functional performance is improved, but the assembly time and labor cost increase
Solution Approach 1:
By combining multiple functional components into a single clipping component, the number of assembly steps is dramatically reduced. Instead of assembling blocking member, floating plug, connecting sleeve, and cap separately, the simplified design requires assembling only the clipping component and cap, significantly reducing assembly time and labor cost.
3Ease of manufacture
If a simple structure with fewer components is used, then the manufacturing cost and assembly time are reduced, but the ability to reliably block liquid flow may be compromised
Solution Approach 1:
The clipping component concentrates its blocking function in a specific local area - the blocking portion that directly contacts the passage. This localized design ensures reliable flow blocking at the critical point while keeping the overall structure simple and easy to manufacture.
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 results in a more cost-effective and efficient manufacturing process with a convenient usage experience, as it allows easy flow of liquid cosmetics when open and prevents leakage when closed.
Implementation Method 1
the cap has a squeezing portion on an inner side, which will compress the opening end of the clipping component so as to block the passage of the applying component
Implementation Method 2
The clipping element has an opening end, and two gaps extending through the opening end, therefore the opening end is compressible and capable of springing back to an open position
