Cup Lid with Elastic Retractable Drinking Spout for Compact Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cup lids with retractable drinking spouts are either overly complex in structure or inadequate in user experience due to issues with spout length and ease of use.
Innovation Solution
A cup lid design featuring a retractable drinking spout with an elastic mechanism, a cover for controlled extension and retraction, and a sealing ring with annular valve to prevent backflow, ensuring the spout automatically extends when needed and retracts when not in use, enhancing usability and simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the drinking spout protrudes longer from the cup lid body, then it is more conducive to drinking water, but the overall height of the cup lid increases
Solution Approach 1:
The drinking spout is designed to be movable rather than fixed, allowing it to extend when needed for drinking and retract when not in use. The elastic part enables the spout to dynamically adjust its position, providing drinking convenience when extended while maintaining a compact cup lid height when retracted.
Solution Approach 2:
The drinking spout can be retracted into the cup lid body, nesting within the through hole when not in use. This nesting mechanism allows the spout to be hidden inside the cup lid structure, maintaining a compact overall height while still providing extended access when needed.
2Length of stationary object
If the drinking spout protrudes shorter from the cup lid body, then the cup lid height is reduced, but it is not conducive to drinking water
Solution Approach 1:
The elastic part enables the drinking spout to dynamically extend when needed for drinking, ensuring sufficient protrusion length for convenience, and automatically retract when not in use to maintain a compact cup lid height.
3Ease of operation
If a retractable straw structure is used to achieve retractable drinking spout effect, then the spout can extend and retract, but the cup lid structure becomes more complicated
Solution Approach 1:
The cup lid is divided into functional segments: the through hole for spout movement, the elastic part for providing retractable force, and the cover for controlling extension. This segmentation allows each component to perform its specific function simply, avoiding the need for a complex integrated retractable straw mechanism.
Solution Approach 2:
The elastic part automatically provides the force needed for the spout to extend and retract without requiring complex mechanical mechanisms. The system uses the elastic property of the material itself to achieve the retractable effect, eliminating the need for motors, springs, or other complex actuating mechanisms.
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 provides a convenient, automatic, and leak-proof retractable spout mechanism that simplifies assembly and improves user experience by ensuring the spout is accessible when needed and hidden when not in use, maintaining a compact form.
Implementation Method 1
an elastic part arranged in the through hole and having one end in butting connection with the base and the other end in butting connection with the drinking spout, the elastic part pushing the drinking spout to stretch out when popping up, and the elastic part being compressed to accumulate force when the drinking spout retracts
