Wet Wipe Flip Cover Elastic Bar for Automatic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flip covers for wet wipe boxes require manual effort to open and close, leading to potential moisture loss and bacterial growth when not properly closed.
Innovation Solution
A flip cover design featuring an upper flip cover with a connecting elastic bar, a fixing cover, and a lower drawing cover with a drawing port, allowing for automatic closure when the upper flip cover is opened and forgetting to close, utilizing elastic engagement mechanisms to ensure secure sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper flip cover is directly connected with the lower drawing cover through injection molding or a connecting rod, then the structure is simple, but the flip cover requires manual effort to open and close and does not automatically close
Solution Approach 1:
The elastic bar serves as a self-service mechanism that automatically closes the flip cover without requiring user intervention. When the flip cover is opened, the elastic bar stores elastic potential energy and automatically returns to its original shape, driving the flip cover back to the closed position, thus making the system self-regulating
Solution Approach 2:
The elastic bar acts as an intermediary element between the flip cover and the drawing cover. It transmits force and motion between these two components, enabling automatic closing while isolating the complexity of the elastic mechanism from both the flip cover and drawing cover structures
2Reliability
If manual force is applied to open and close the flip cover, then the structure is simple, but moisture loss and bacterial growth occur when not properly closed
Solution Approach 1:
The elastic bar provides continuous feedback through its elastic deformation state. When the flip cover is opened, the elastic bar deforms and stores energy, creating a restoring force that continuously pushes the flip cover toward the closed position. This feedback mechanism ensures the cover returns to the sealed state automatically
Solution Approach 2:
The elastic bar is pre-loaded with elastic potential energy in its relaxed state. This preliminary stored energy is ready to act immediately when the flip cover is opened, ensuring rapid and reliable automatic closing without requiring user attention or delayed action
3Reliability
If the elastic bar is used to achieve automatic closing, then the sealing reliability is improved, but the device complexity increases
Solution Approach 1:
The elastic closing mechanism is extracted as a separate, independent component (the elastic bar) that can be easily installed and removed. This modular approach allows the complex elastic mechanism to be isolated from the main cover structures, simplifying manufacturing and maintenance while maintaining automatic closing functionality
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 design enhances convenience and prevents moisture loss and bacterial growth by ensuring the flip cover automatically closes, maintaining the wetness and hygiene of the wet wipes.
Implementation Method 1
the two ends of the connecting elastic bar are connected with the fixing cover and the flip cover, respectively... when the applying force drives the flip cover to a certain angle, the flip cover upwards and automatically turns along the connection edges of the elastic bar and the fixing cover under the drive of the connecting elastic bar; and when the applying force is released within certain angle, the flip cover will automatically and downwards turn and be engaged with the lower drawing cover under the drive of the connecting elastic bar
