Solution Overview
Problem
Existing beverage container lids suffer from hot air and liquid ejection issues when transitioning from a stowed to an open configuration, leading to user burns and difficulty in cleaning and replacing worn-out parts due to non-disassemblable designs.
Innovation Solution
A lid assembly with a trigger mechanism and pivotable spout that allows controlled release of internal pressure before full opening, featuring disassemblable parts for easy cleaning and replacement, including a first lid, second lid, trigger mechanism, and pivotable spout with engagement and interaction means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the spout is designed to pivot from stowed to open configuration, then beverage dispensing is enabled, but hot air pressure and hot drinks are quickly ejected out of the spout causing user burns
Solution Approach 1:
The lid assembly introduces a pressure relief valve that opens before the spout to release accumulated hot air pressure in advance. This preliminary action prevents the sudden ejection of hot air and liquid when the spout opens, thereby resolving the technical contradiction between enabling spout operation and preventing user burns from hot air and liquid ejection
2Ease of manufacture
If the lid assembly is manufactured as one-piece, then manufacturing is simplified, but cleaning becomes difficult and parts cannot be replaced when damaged or worn out
Solution Approach 1:
The lid assembly is divided into multiple separable components including the lid body, spout assembly, and seal elements. This segmentation enables each component to be independently removed for thorough cleaning and allows replacement of worn or damaged parts such as seals and gaskets, thereby resolving the technical contradiction between simplified one-piece manufacturing and ease of cleaning and repair
