Solution Overview

Problem

Existing lid assemblies for drinking containers are complex, difficult to clean, and prone to contamination due to intricate mechanisms that complicate the separation and alignment of components, leading to issues with durability, reliability, and user-friendliness.

Innovation Solution

A lid assembly design featuring a releasable mounting member with resilient elements that allows for easy detachment from the lid housing, enabling thorough cleaning and alignment, with a circumferential support frame providing structural support and facilitating the passage of drinking liquid, while maintaining a compact and user-friendly interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the lid assembly uses a complex mechanism with multiple components to enable opening and closing of the drinking opening, then the functionality and user control are improved, but the ease of cleaning deteriorates due to difficulty in separating and accessing all components

Engineering Contradiction:
ImprovefunctionalityVSAvoidease of cleaning
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The lid assembly is divided into separable components: the sealing assembly can be detached from the lid housing, and the actuator element can be removed from the sealing assembly. This segmentation allows each component to be cleaned separately, addressing the cleaning difficulty while maintaining the complex functional mechanism during operation.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the guide members and guide tracks are positioned non-centrally to enable separation of the sealing assembly, then the ease of cleaning is improved, but the device complexity increases due to careful alignment requirements

Engineering Contradiction:
Improveease of cleaningVSAvoidalignment complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The guide tracks are positioned asymmetrically and non-centrally on the lid housing, while the guide members on the sealing assembly correspondingly match this asymmetric positioning. This asymmetric design enables straightforward connection without requiring precise central alignment, reducing alignment complexity while facilitating easy separation for cleaning.

Inventive Principle:
Principle #4Asymmetry

3Reliability

If the locking assembly has multiple positions to lock the sealing element in opened and closed states, then the reliability is improved, but the device complexity increases making it difficult to manufacture and maintain

Engineering Contradiction:
Improvelocking reliabilityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking function is extracted as a separate locking element that can engage with the actuator element at different positions. This extracted locking mechanism provides reliable multi-position locking while maintaining simplicity in manufacturing and maintenance, avoiding the need for a complex integrated locking assembly.

Inventive Principle:
Principle #2Taking out (Extraction)

4Volume of moving object

If the sealing assembly has small overall dimensions and fine structure to maintain compactness, then the volume is reduced, but the ease of cleaning deteriorates due to difficulty in accessing small components

Engineering Contradiction:
ImprovecompactnessVSAvoidease of cleaning
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The sealing assembly is designed as a separable component that can be completely detached from the lid housing. This segmentation allows the small, fine-structured sealing assembly to be removed and cleaned separately, making it accessible despite its compact dimensions, while maintaining the space-efficient design when assembled.

Inventive Principle:
Principle #1Segmentation

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 solution enhances the cleanability and durability of the lid assembly by allowing for quick and easy disconnection of the mounting member and sealing assembly from the lid housing, ensuring thorough cleaning and reducing the risk of contamination, while maintaining a compact and user-friendly design.

Implementation Method 1

The first resilient element and the second resilient element are biased for pressing against the side wall (13) of the lid housing (10) for connecting the mounting member (30) to the lid housing (10).
