Lid structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wide-mouth water bottles with threaded lids are inconvenient for users, leading to difficulties in drinking large amounts of water quickly and potential water leakage.
Innovation Solution
A lid structure featuring a main lid with a straw, an upper lid, and a locking assembly that allows the straw to be bent and locked, with a puller and elastic member to facilitate one-button opening and prevent water leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a threaded lid structure is used for wide-mouth water bottles, then the lid can be securely attached to the bottle body, but it is inconvenient for users to drink large amounts of water quickly and may cause water leakage
Solution Approach 1:
The lid structure employs dynamic elements including a movable locking pin that can shift between locked and unlocked positions, a rotatable puller mechanism, and a flexible straw that can bend. These dynamic components allow the lid to transition between secure attachment state and easy opening state, resolving the contradiction between secure attachment and convenient operation for drinking large amounts of water quickly
Solution Approach 2:
The lid is divided into multiple functional segments: an upper lid portion with the straw assembly, a main lid body with the locking mechanism, and a separate puller component. This segmentation allows each part to perform its specific function independently - the upper lid seals, the main lid attaches to the bottle, and the puller operates the locking mechanism, thereby achieving both secure attachment and convenient operation
2Ease of operation
If a simple threaded lid is used, then the structure is simple to manufacture, but it does not provide convenient one-button opening functionality
Solution Approach 1:
The locking pin, puller, and elastic member are merged into an integrated locking assembly where the puller rotates to simultaneously move the locking pin and compress/release the elastic member. This merging allows one-button operation while distributing the complexity across multiple integrated components that work together, rather than requiring separate mechanisms for each function
3Ease of operation
If a locking mechanism is added to enable one-button opening, then convenience of use is improved, but the device complexity increases
Solution Approach 1:
The elastic member automatically returns the locking pin to its locked position after being compressed by the puller, and the buckling structure automatically secures the upper lid to the main lid without requiring additional user actions. This self-service mechanism reduces the need for complex control systems while maintaining one-button opening functionality, thereby improving ease of operation without proportionally increasing device complexity
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 enables convenient and simple use, allowing quick drinking and preventing water leakage, enhancing user experience for wide-mouth water bottles.
Implementation Method 1
a first elastic member disposed between the puller and the main lid to drive the locking pin to move inward along the radial direction
Implementation Method 2
a second elastic member forcing the dust cover to open the opening is disposed between the second supporting portion and the dust cover

AI summary
Disclosed is a lid structure. An upper lid of the lid structure is buckled to a main lid, the upper lid is provided with an opening for a straw to extend out, a 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 in an inner hole in an end portion of the straw, so that water leakage can be avoided when the straw is bent. Due to the fact that when the straw is bent, the locking assembly can move along the radial direction of the main lid to be inserted and locked in the inner hole in the end portion of the straw, the straw is prevented from getting upright due to the bouncing force thereof to result in water leakage.
