Linkage-Driven Lid Assembly for Fast One-Handed Spout Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lid assemblies for drinking containers lack a simplified design that allows for quick and easy operation of the spout between open and closed positions using a handle, and do not effectively adjust resistance force and response time.
Innovation Solution
A lid assembly featuring a spout that is pivotably mounted to a main body and connected through a linkage system with a handle, comprising link members that facilitate smooth movement between open and closed positions, allowing for effortless one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bent or folded spout mechanism is used to close the liquid passage, then the liquid passage can be closed by applying downward pressure on the lid, but the mechanism lacks speed in operation and is structurally complex
Solution Approach 1:
The spout mechanism is segmented into distinct functional components: the spout itself, the linkage system with link members, and the handle. This segmentation allows each component to perform its specific function independently, simplifying the overall structure while maintaining ease of operation. The linkage system breaks down the complex motion control into simpler, manageable segments that work together smoothly.
Solution Approach 2:
The linkage system acts as an intermediary between the handle and the spout, translating the simple downward pressure applied to the handle into controlled movement of the spout between open and closed positions. This intermediary mechanism reduces the structural complexity by providing a straightforward mechanical connection that efficiently transmits force without requiring complex control systems.
2Adaptability or versatility
If existing spout mechanisms are used, then the liquid passage can be closed, but they lack capability to adjust resistance force and response time
Solution Approach 1:
The linkage system provides dynamic adjustability through the movement of link members that can change the mechanical advantage ratio. By adjusting the position and configuration of the link members, the resistance force required to open or close the spout can be dynamically adjusted, and the response time can be modified by changing the linkage geometry. This dynamic capability is achieved without adding significant complexity to the overall mechanism.

AI summary
The present invention is related to a lid assembly, for a container, comprising: a main body, removably mounting to said container, said main body is provided with a receiving chamber and a passage fluidically communicable with the interior of said container; a spout, configured to provide an internal thoroughly-hollow bore and to sit over said passage and to pivotably mounted to said main body in said receiving chamber, such that said spout is movable between a first position where said passage and said bore being communicable and a second position where said passage and said bore being not communicable; a handle, operatively connecting to said spout and to said main body; a connecting member, having a first end movably connecting to said spout and a second end connecting to said handle; and characterized in that, the connection between said spout, said connecting member, and said handle define a linkage system, whereby the movement of said handle actuates the movement of said spout.
