Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing beverage container lids fail to effectively prevent ice from escaping or blocking the drinking opening, leading to ice contacting the user's lips or escaping through the opening.

Innovation Solution

A beverage container lid with baffles at the drink opening that block ice cubes or chips from escaping and hold them away from the user's lips, allowing liquid to pass unimpeded.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple lid opening is used, then the device complexity is reduced, but ice cubes or chips can escape or block the opening

Engineering Contradiction:

Improvelid structureVSAvoidice prevention

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The lid structure is segmented by adding multiple baffle members (34) that divide the interior space into separate regions. These baffles create a first region away from the opening where ice is contained, and a second region near the opening for liquid flow, preventing ice from blocking or escaping the opening while maintaining structural organization

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The baffle members act as intermediary elements between the ice cubes/chips and the drinking opening. By positioning these baffles in the interior space, they serve as a protective barrier that indirectly prevents ice from contacting the opening, allowing liquid to pass through while blocking ice movement

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If baffles are added to block ice, then ice prevention is improved, but the device complexity increases

Engineering Contradiction:

Improveice preventionVSAvoidlid structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The baffle members are strategically positioned only in specific locations where ice prevention is needed - adjacent to the drinking opening and extending toward the interior space. This localized approach provides effective ice blocking where required while minimizing unnecessary structural complexity in other areas of the lid

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If baffles are positioned to block ice, then ice contact with lips is prevented, but liquid flow may be impeded

Engineering Contradiction:

Improveice contact with userVSAvoidliquid flow

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The baffle members are designed with specific spacing and positioning that allows dynamic liquid flow while maintaining static ice blocking. The gaps between baffles and their orientation enable liquid to pass through unimpeded, while the same structure creates effective barriers against ice cubes and chips due to their larger size and different flow characteristics

Inventive Principle:

Principle #15Dynamics
