Solution Overview

Problem

Existing drinkware lids with sipper holes and straws require users to change hands or turn the mug to switch between consumption modes, which can be inconvenient.

Innovation Solution

A dual function lid design featuring a pivotable flap and rotatable spout that allows users to switch between drinking through a sipper hole and a sipper straw without changing hands or turning the mug, with the spout rotating over 90 degrees to align with a central straw receptacle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a lid has both a sipper hole and a sipper straw, then the beverage can be consumed through multiple openings, but the user must turn the mug or change hands to switch between openings

Engineering Contradiction:

Improvedrinking mode switchingVSAvoidhand position stability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The spout is made rotatable relative to the lid body, allowing it to rotate between a first position (blocking the second opening) and a second position (unblocking the second opening). This dynamic element enables the user to switch between drinking modes by simply rotating the spout while keeping the mug in the same hand and orientation.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the spout rotates to unblock the second opening, then the user can drink through the sipper straw, but the first opening must be blocked to prevent leakage

Engineering Contradiction:

Improvedrinking mode switchingVSAvoidsealing performance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The lid is divided into separate functional components: a lid body with two openings, a spout that can rotate, and a flap that can pivot. The spout includes a first seal that seals the first opening when the spout is in the first position, and a second seal that seals the second opening when the spout is in the second position. This segmentation allows each component to have a specific sealing function, ensuring reliable sealing performance while enabling mode switching.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The flap acts as an intermediary element between the two openings. When the spout is rotated to the second position to enable drinking through the sipper straw, the flap pivots to block the first opening. This intermediary mechanism ensures that only one opening is active at a time, preventing leakage while allowing versatile drinking mode switching.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Embodiments of a multifunction lid and drink container are described. The lid includes a sipping drink opening and a drink spout. The lid is configured to allow the user holding the drink container in one hand to drink from either the spout or the drink opening without rotating the lid body or changing hands holding the drink container.
