Solution Overview

Problem

Existing beverage serving trolleys face difficulties in refilling and cleaning due to complicated presentation basket handling and storage, as the basket is often not easily removable.

Innovation Solution

A beverage serving trolley with an improved presentation basket featuring a one-piece plastic component, a basket handle for balanced carrying, removable ice packs, a sheet metal tray for stabilization, and a light module for enhanced presentation, allowing easy removal and refilling, along with footstands for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the presentation basket is integrated into the beverage serving trolley, then beverage presentation and cooling are improved, but refilling and cleaning become complicated

Engineering Contradiction:
Improvebeverage presentation and coolingVSAvoidrefilling and cleaning
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The presentation basket is designed as a separate, removable component from the beverage serving trolley. It features a standardized interface with the trolley's supporting structure, allowing it to be easily detached and reattached. This segmentation enables users to remove the basket for refilling or cleaning without disassembling the entire trolley system, thus maintaining reliable beverage presentation while significantly improving ease of operation.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the presentation basket is made stable and integrated, then beverage storage is secure, but the basket cannot be easily removed

Engineering Contradiction:
Improvebasket stabilityVSAvoidbasket removal
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection between the presentation basket and the beverage serving trolley is designed to be dynamically adjustable. The basket includes engagement features that provide stable fixation during normal use, preventing accidental displacement. However, when intentional removal is required, the connection can be easily disengaged through a simple lifting or releasing motion. This dynamic design maintains stability during operation while enabling easy removal when needed.

Inventive Principle:
Principle #15Dynamics

3Strength

If the presentation basket has thick walls for stability, then structural strength is improved, but temperature conductivity increases reducing cooling efficiency

Engineering Contradiction:
Improvebasket structural strengthVSAvoidcooling efficiency
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The presentation basket is constructed using composite materials that combine structural strength with thermal insulation properties. The basket body uses a material or structure (such as thick-walled plastic or insulated composite) that provides sufficient mechanical strength to support beverage bottles while simultaneously acting as a thermal barrier. This composite construction maintains the required structural integrity while preventing excessive heat transfer, thereby preserving cooling efficiency without sacrificing strength.

Inventive Principle:
Principle #40Composite materials
