Solution Overview

Problem

Conventional drink coasters are either stationary or lack a stable structure, making them unsuitable for holding beverages of varying sizes securely while being mobile.

Innovation Solution

A rolling drink coaster design featuring a top assembly with stabilizers and a bottom plate equipped with rollers, allowing the coaster to be mobile while securely holding beverages of different sizes through the use of stabilizers that provide additional cushioning and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If drink coasters are made stationary to provide stability, then beverage containers can be held securely, but the coasters cannot be moved easily

Engineering Contradiction:
ImprovestabilityVSAvoidmobility
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The coaster incorporates rollers at the bottom that allow it to transition from a static stable structure to a mobile unit when needed. The rollers enable easy movement across surfaces while the coaster body maintains its stable configuration to hold beverages securely.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If drink coasters are made mobile with wheels or rollers, then they can be moved easily, but they lack a stable structure to prevent beverages from falling out

Engineering Contradiction:
ImprovemobilityVSAvoidstability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The coaster is divided into distinct functional segments: a stable upper body structure with vertical walls and an insert piece for securing beverages, and a separate roller mechanism at the bottom for mobility. This segmentation allows each part to optimize its specific function without compromising the other.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If drink coasters have a simple flat or cylindrical shape, then they are easy to manufacture, but they cannot accommodate drinks of varying sizes securely

Engineering Contradiction:
Improveease of manufactureVSAvoidadaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The coaster body is segmented into an outer shell and an inner insert piece. The insert piece can be designed with adjustable or flexible elements that adapt to different beverage container sizes and shapes, while the overall simple coaster structure remains easy to manufacture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert piece within the coaster has specialized local characteristics (such as cushioning material or adjustable walls) that provide adaptability to different drink sizes, while the main coaster body maintains a simple geometry for ease of manufacturing.

Inventive Principle:
Principle #3Local quality

AI summary

One or more embodiments for a rolling drink coaster. The rolling drink coaster includes a top assembly coupled to a bottom plate. A plurality of rollers are disposed on an underside of the rolling drink coaster that allow the drink coaster to roll and to be movable over a surface. An interior cavity of the rolling drink coaster is configured to hold a beverage container. The rolling drink coaster includes one or more stabilizer pieces configured to support and stabilize the beverage container when located inside of the rolling drink coaster. The rolling drink coaster may have an angled top body or a straight cylindrical shaped top body. In one embodiment, a bottom plate is fastened to a bottom surface of the top assembly of the rolling drink coaster. The bottom plate is configured to receive one or more axel assemblies that surround each roller and allow the drink coaster to move.
