Drinking lid for a drinking container, and drinking container having such a lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 360° drinking attachments face challenges in assembly after cleaning, as the alignment of openings for liquid passage is laborious and often not precise, leading to suboptimal cleaning results, and they lack effective air supply mechanisms to prevent negative pressure during liquid extraction.
Innovation Solution
A 360° drinking attachment design featuring a two-part trinkrand with separate materials for the mounting and drinking sections, and a sealing disk with stiffening ribs and air inlet passages to simplify assembly and ensure proper sealing, allowing for easy alignment and effective air flow to prevent negative pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sealing disk is designed to be lifted by suction action to release liquid passage, then liquid flow is enabled, but precise alignment of openings becomes laborious and difficult after cleaning
Solution Approach 1:
The trinkrand is divided into two separate parts: a first part with a mounting portion and a second part with a drinking section. This segmentation allows each part to be manufactured and assembled independently, eliminating the need for precise alignment of openings between components after cleaning.
Solution Approach 2:
The seal element is extracted as a separate component that can be removed and cleaned independently from the trinkrand parts. This allows the seal element to be replaced or reinstalled without requiring precise alignment of multiple openings, simplifying the cleaning and reassembly process.
2Reliability
If the seal element is tightly applied to prevent leakage, then sealing performance is improved, but air supply is restricted causing negative pressure during liquid extraction
Solution Approach 1:
The seal element is designed with differentiated local properties: it provides tight sealing at the interface between the trinkrand and drinking vessel to prevent leakage, while simultaneously incorporating air inlet passages that allow air to flow through specific locations to prevent negative pressure buildup during liquid extraction.
3Device complexity
If the trinkrand is made as a single integrated piece, then structure is simplified, but assembly after cleaning becomes laborious and imprecise
Solution Approach 1:
The trinkrand is divided into two separate parts: a first part with a mounting portion and a second part with a drinking section. This segmentation allows each part to be manufactured and assembled independently, eliminating the need for precise alignment of openings between components after cleaning.
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 simplifies assembly, enhances sealing stability, and ensures efficient fluid flow without the need for precise alignment, while the air inlet passages prevent negative pressure and pulsation during liquid extraction.
Implementation Method 1
a substantially elastic so-called in the trin-crown comprising a sealing disk for sealing the trin-edge
Implementation Method 2
an air inlet passage which is designed to allow air to flow into the drinking vessel
