Solution Overview

Problem

Existing sippy cups are limited in their useful lifespan as children grow, as they often require complex reconfiguration that can lead to handles becoming trapped and falling during refilling.

Innovation Solution

A convertible beverage container with a secure handle structure that can be removably mounted on either the lid or base structure, allowing for easy reconfiguration without the handle falling during refilling, and featuring a design that prevents gaps that could pinch small fingers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the handle structure is integrated into the sippy cup design to assist small hands, then ease of operation is improved, but device complexity increases and the handle may become trapped during refilling

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

Solution Approach 1:

The handle structure is designed as a separate, removable component that can be detached from the cup body. This segmentation allows the handle to be easily removed during refilling operations, preventing the trapping issue while maintaining ease of handling when attached. The handle can be independently manipulated without requiring disassembly of the entire cup structure.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the sippy cup design includes fixed handles for small hands, then ease of operation is improved, but adaptability decreases as the child grows

Engineering Contradiction:
Improveease of handlingVSAvoidusability across development stages
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The handle structure transitions from a fixed configuration to a dynamic, adjustable configuration. The handle can be removed and repositioned, allowing the cup to adapt to the child's growing hand size and changing needs. This dynamic design enables the same cup to serve effectively across multiple stages of drinking development, from early sippy cup use to later independent cup handling.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the lid is designed to securely close the container, then reliability is improved, but ease of operation worsens when refilling is needed

Engineering Contradiction:
Improveliquid retentionVSAvoidease of refilling
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The handle structure is pre-configured to be removable before the lid is fully secured. This preliminary action allows the handle to be detached in advance, creating clear access to the cup interior for refilling operations. The design anticipates the refilling need and prepares the structure accordingly, maintaining reliable liquid retention when closed while enabling easy refilling when needed.

Inventive Principle:
Principle #10Preliminary action

AI summary

A convertible beverage container may have a base structure having an interior configured to hold a liquid, and a lid structure removably mountable on the base structure over an open top to selectively close the open top. The lid structure may have a mounted condition characterized by the beverage container being able to at least partially retain a liquid in the interior of the base structure and an unmounted condition characterized by the beverage container being unable to retain a liquid in the interior of the base structure. The beverage container may further include a handle structure directly and removably mountable on the lid structure such that the handle structure is mountable on the base structure via the mounting of the handle structure on the lid structure when the lid structure is mounted on the base structure.
