Auto-opened water cup lid with press-type nozzle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water cup lids require manual operation to open the straw, making it inconvenient for users to access water, and existing solutions with straws still face issues with dust accumulation and operational hassle.
Innovation Solution
An auto-opened water cup lid with a press-type nozzle featuring a button-activated mechanism that automatically opens the nozzle and nozzle cover, utilizing a rotating sleeve and spring system to facilitate easy water access while preventing dust entry and maintaining a clean drinking experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a straw cover is used to cover the straw, then dust and impurities are prevented from adhering to the drinking part, but the straw cover needs to be manually flipped open and the straw raised, which is still inconvenient
Solution Approach 1:
The button-activated mechanism automatically opens the nozzle and raises the straw without requiring manual flipping or lifting operations. When the button is pressed, the spring-driven mechanism self-activates to open the nozzle cover and elevate the straw to the drinking position, making the system serve itself rather than requiring continuous manual intervention
Solution Approach 2:
The straw and nozzle are pre-positioned in a closed state with the straw lowered and nozzle covered when not in use. The button mechanism is pre-loaded with spring energy that is ready to automatically execute the opening and raising actions upon activation, preparing the system in advance for quick deployment
2Ease of operation
If the nozzle opens automatically when the hook is disengaged, then ease of operation is improved, but the nozzle cover must be securely closed when not in use to prevent dust entry
Solution Approach 1:
The hook mechanism is designed to maintain a preliminary locked state that prevents accidental opening. The hook engages with the nozzle cover to secure it in the closed position, and only deliberate button pressure sufficient to overcome the spring force and disengage the hook will trigger the opening action, preventing unintended activation
Solution Approach 2:
The button acts as an intermediary control element between the user and the opening mechanism. It mediates the transition from closed to open state by controlling the disengagement of the hook, providing a controlled and intentional activation method that balances ease of operation with secure closed state maintenance
3Ease of operation
If the nozzle is positioned opposite to the handle direction, then usability is enhanced by preventing handle blockage, but the internal mechanism becomes more complex
Solution Approach 1:
The straw and nozzle assembly is designed with dynamic positioning capability through the rotating sleeve mechanism. The straw can rotate and position itself in different orientations, including the optimal position opposite the handle, allowing the system to adapt its configuration dynamically rather than being fixed in a single position
Solution Approach 2:
The nozzle assembly is segmented into separate rotatable components (straw, rotating sleeve, nozzle cover) that can independently position themselves. This segmentation allows each component to be optimized for its specific function while collectively achieving the desired opposite-handle positioning without requiring a completely redesigned complex mechanism
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 auto-opened mechanism allows for effortless water consumption by simply pressing a button, ensuring the nozzle opens automatically, reducing manual effort and preventing dust entry, while the design enhances usability and appearance by positioning the nozzle opposite to the handle direction.
Implementation Method 1
The spring is arranged in the button slot, and a button is arranged on one side of the button slot. The button has a pin and a pulling plate. The pin has a barb. The pin is inserted into the button slot, and the barb cooperates with the position-limiting hole.
Implementation Method 2
A straw made of soft rubber material is disposed in the perforation, and the straw is provided with a nozzle. When the hook is disengaged from the hook slot, the resilient force of the straw drives the nozzle, the rotating sleeve and the nozzle cover to be opened automatically.
