Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing coasters and napkins do not effectively address the issue of condensation trickling down the bowl of stemware glasses, leading to discomfort and potential drips onto patrons or surfaces.

Innovation Solution

A coaster designed with a planar body, a centralized opening with a diagonal radial slit, and straight radial perforated slits that allow it to snugly fit over the stem of a stemware glass, absorbing moisture as it reaches the foot of the glass.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If coasters are designed with intricate constructions to prevent sticking, then the stemware can be easily removed, but branding and advertising effectiveness is reduced

Engineering Contradiction:

Improveease of removing stemwareVSAvoidbranding accommodation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The coaster is divided into distinct functional segments: a stem-wrapping portion with release tabs for easy removal, a base portion for stability, and a bowl portion for condensation absorption. This segmentation allows different areas to serve different purposes while maintaining overall functionality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the coaster have different properties optimized for their specific functions. The stem portion features release tabs for ease of removal, the base portion provides stability, and the bowl portion offers maximum absorbency. Branding can be applied to any or all portions depending on advertising needs

Inventive Principle:

Principle #3Local quality

2Productivity

If a tray is used to transport multiple drinks and coasters, then bar staff can efficiently serve beverages, but the process becomes more complex and time-consuming

Engineering Contradiction:

Improveefficiency of beverage serviceVSAvoidcomplexity of serving process

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The coaster design integrates multiple functions into a single unit: stem wrapping for stability, condensation absorption to prevent drips, and table protection. By combining these functions, the coaster eliminates the need for separate protective items, simplifying the serving process while maintaining efficiency

Inventive Principle:

Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The coaster effectively intercepts and contains moisture from the stemware bowl, enhancing the drinking experience by preventing discomfort and drips, while also allowing for branding and advertising opportunities.

Implementation Method 1

a coaster for stemware glasses... the body is composed of an absorbent material... intercepts and contains moisture from the stemware bowl, absorbing it as it reaches the upper part of the foot

Methodology Applied

Scientific EffectAbsorption: Absorption (physical)

Implementation Method 2

the straight radial perforated slit expands to permit that body of the coaster to sit substantially flat on the top surface of the foot of the stemware glass

Methodology Applied

Scientific EffectCapillary action: Capillary Action
