Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded bottle stopper is used, then the sealing performance is improved, but the ease of operation deteriorates due to complicated rotation required during use
Solution Approach 1:
The stopper is divided into a fixed shell and a movable stopper body that can slide relative to each other. The sealing function is segmented from the opening/closing operation, allowing the seal to remain engaged while the stopper body moves for opening/closing actions.
Solution Approach 2:
The stopper transitions from a static threaded design to a dynamic sliding mechanism. The movable stopper body can slide along the fixed shell, enabling quick opening and closing without rotation, while the elastic sealing sleeve maintains continuous sealing pressure.
2Ease of operation
If a solid rubber stopper is used, then the ease of operation is improved, but the reliability deteriorates due to poor sealing performance and short service life
Solution Approach 1:
The stopper combines a rigid fixed shell structure with a flexible elastic sealing sleeve. This composite design provides both the ease of operation from the movable body and the reliable sealing from the elastic material that deforms to seal tightly.
Solution Approach 2:
The elastic sealing sleeve changes its physical parameters (shape, volume, density) under compression to achieve effective sealing. When the stopper body moves, the sealing sleeve deforms elastically to maintain contact and sealing pressure with the container opening.
3Ease of manufacture
If a simple rubber stopper design is used, then the manufacturing cost is reduced, but the reliability deteriorates due to poor sealing and short service life
Solution Approach 1:
The stopper is segmented into a simple fixed shell and a movable stopper body with a sealing sleeve. This segmentation allows each component to be manufactured separately using simple processes, reducing overall manufacturing complexity and cost while improving reliability through functional specialization.
4Reliability
If a threaded bottle stopper is used, then the sealing performance is improved, but the time required for operation increases due to complicated rotation
Solution Approach 1:
The stopper uses a dynamic sliding mechanism instead of static rotation. The movable stopper body slides along the fixed shell in a linear motion, dramatically reducing the time and effort required for opening and closing while the elastic sealing sleeve ensures continuous sealing.
Solution Approach 2:
Instead of rotating the stopper to open/close it (conventional approach), the invention inverts the mechanism by sliding the stopper body linearly. The sealing is maintained through the elastic deformation of the sealing sleeve rather than through threaded engagement.
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 container stopper provides easy and quick operation, long service life, good sealing performance, and low production costs, making it convenient and efficient for daily use.
Implementation Method 1
An elastic sealing sleeve abuts against and between the limiting plate and the fixed shell... the whole elastic sealing sleeve is squeezed by the limiting plate and the fixed shell, so that the elastic sealing sleeve bulges outward to seal the container
Implementation Method 2
A first elastic member is connected between the first connector and the second connector. While the knob switches from the locked state to the unlocked state, the first elastic member is extended and tightened... the knob is rotated under the pulling force of the first elastic member

AI summary
The present disclosure relates to the field of bottle stopper devices, and in particular, to a quick opening and closing container stopper, which includes a fixed shell and a movable stopper body. The fixed shell is provided with a dodging opening. The movable stopper body is provided with a limiting plate. An elastic sealing sleeve abuts against and between the limiting plate and the fixed shell. A knob is rotatably connected to the movable stopper body. The knob includes a side lug. When the container stopper is in a locked state, the side lug extends beyond a contour range of the dodging opening, and the fixed shell and the limiting plate are close to each other and drive the elastic sealing sleeve to bulge outward. When the container stopper is in an unlocked state, the side lug is accommodated in the dodging opening.
