One-Handed Cosmetic Bottle Cap With Limit Claw Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic bottles require both hands to open and close, making them inconvenient for single-handed use, especially during activities like making or receiving phone calls, which disrupts makeup application.
Innovation Solution
A cosmetic bottle design featuring a bottle cap and body with a limit ring, limit claws, and a sealing body that allows for one-handed operation through a pull-press mechanism, utilizing elastic clips and annular grooves to securely fasten and seal the cap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded connection structure is used for the bottle cap, then the bottle cap can be securely fastened to the bottle body, but both hands are required to open and close the cap, reducing ease of operation
Solution Approach 1:
The opening and closing operation is segmented into two independent actions: pressing the button body downward to expand the elastic clip, and then rotating the bottle cap. This segmentation allows the first action to be performed with one hand while the second action secures the cap, enabling one-handed operation while maintaining secure fastening through the threaded connection.
Solution Approach 2:
A button body with an elastic clip acts as an intermediary mechanism between the user's finger and the bottle cap threading. The elastic clip expands when pressed, providing a mechanical advantage that allows single-handed operation of the threaded connection, thus resolving the contradiction between secure fastening and ease of one-handed operation.
2Reliability
If a threaded connection structure is used for the bottle cap, then the bottle cap can be securely fastened to the bottle body, but the opening and closing process takes more time, reducing productivity
Solution Approach 1:
The elastic clip is pre-compressed by pressing the button body downward before the rotating action. This preliminary action prepares the mechanical system to engage more quickly with the threaded connection, reducing the overall time required for opening and closing operations while maintaining secure fastening, thus improving productivity during makeup application.
Solution Approach 2:
The elastic clip provides a dynamic mechanical advantage that changes during the opening and closing process. When compressed, it stores energy that facilitates quicker engagement with the threads, making the operation faster while still achieving secure fastening. This dynamic mechanism resolves the contradiction between secure fastening and operational speed.
3Ease of operation
If a simple cap structure is used, then ease of operation is improved, but the sealing performance may be compromised
Solution Approach 1:
The sealing structure is nested within the button body and elastic clip assembly. The sealing component is integrated into the existing one-handed operation mechanism, so that the sealing function is achieved without adding separate complex sealing structures. This nested design maintains ease of operation while ensuring reliable sealing performance through the integrated design.
Solution Approach 2:
The button body with elastic clip serves multiple functions: it provides the mechanical advantage for one-handed operation, maintains the threaded connection for secure fastening, and incorporates the sealing function. This multi-functionality resolves the contradiction by achieving reliable sealing without compromising ease of operation, as the same component structure handles both operational simplicity and sealing reliability.
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 quick and convenient one-handed opening and closing of the bottle cap, minimizing disruption to makeup routines by allowing single-handed use.
Implementation Method 1
a lower end of the rod body is provided with a limit claw, and a lower end of the limit claws is bent towards an outer side of the rod body and is elastically deformed
Implementation Method 2
the sealing body is inserted into the bottle cap through the bottle mouth of the bottle body, and the sealing body is inserted into the bottle mouth and the limit protrusion slides over the chamfer of the limit ring, and then gets stuck under the step of the limit ring, thereby sealing the sealing body at the bottle mouth
