Lid Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current water bottle lids are prone to displacement and deformation when pressed for long periods, leading to water leakage.
Innovation Solution
A lid structure comprising a main lid with a straw and an inserting and locking portion, an upper lid buckled to the main lid, and a locking assembly that moves radially to lock with the inserting and locking portion when the straw is bent, preventing water leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the upper lid is pressed against the straw to be bent for sealing water, then water sealing is achieved, but the upper lid undergoes displacement and deformation after long-term use, resulting in water leakage
Solution Approach 1:
The lid is divided into separate components: the upper lid, main lid, and locking assembly. The locking assembly includes a locking pin that can independently engage with the inserting and locking portion on the straw, separating the sealing function from the structural support function. This segmentation allows the upper lid to be pressed for sealing without bearing the entire mechanical load, preventing displacement and deformation.
Solution Approach 2:
The locking pin is pre-positioned to automatically engage with the inserting and locking portion when the straw is bent into the sealing position. This preliminary locking action occurs before use, ensuring the straw maintains its bent shape without requiring continuous pressure on the upper lid, thereby preventing long-term deformation.
2Reliability
If the locking assembly is designed to automatically lock when the straw is bent, then water leakage is prevented, but the device complexity increases
Solution Approach 1:
The locking assembly is designed to automatically engage and lock when the straw is bent into the sealing position. The locking pin moves radially inward under elastic force to engage with the inserting and locking portion without requiring external intervention. This self-service mechanism prevents water leakage while minimizing the need for complex control systems or additional components.
Solution Approach 2:
The locking pin acts as an intermediary element between the straw and the upper lid. It translates the bending motion of the straw into a locking action, mediating the interaction between these components. This intermediary mechanism achieves reliable locking with a simple radial movement, avoiding the need for complex multi-component assemblies.
3Reliability
If the upper lid is continuously pressed to maintain straw bending, then water sealing is maintained, but the operation convenience deteriorates due to difficulty in opening
Solution Approach 1:
The locking pin is designed with radial movability, allowing it to dynamically transition between locked and unlocked states. When the straw is bent, the locking pin automatically engages to maintain sealing. When opening is needed, the locking pin can be easily disengaged by pressing the puller, which moves the locking pin radially outward. This dynamic design maintains sealing reliability while significantly improving opening convenience.
Solution Approach 2:
The locking function is extracted as a separate, independently operable feature through the puller mechanism. The puller can be pressed to release the locking pin from the inserting and locking portion, separating the opening action from the sealing maintenance function. This allows users to easily open the lid by pressing the puller without needing to overcome continuous sealing pressure.
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 lid structure effectively prevents water leakage by keeping the straw bent and securely locked, even when subjected to bouncing forces, while allowing for easy one-button opening for drinking.
Implementation Method 1
a first elastic member is disposed between the puller and the main lid to drive the locking pin to move inwards along the radial direction

AI summary
Disclosed is a lid structure, which includes a main lip, an upper lid and a locking assembly, the main lid is provided with a straw, an inserting and locking portion is disposed on the straw, the upper lid is buckled to the main lid, the upper lid is provided with an opening for the straw to extend out, the locking assembly is disposed between the main lid and the upper lid, and when the straw is bent, the locking assembly can move along a radial direction of the main lid to be inserted and locked with the inserting and locking portion. In the present disclosure, a manner that the locking assembly is matched with the inserting and locking portion on the straw is adopted when there is no need to drink water, so that the straw can be kept bent all the time, which avoids liquid leakage.
