Solution Overview

Problem

Existing beverage serving trolleys are often cluttered and require extensive modifications or multiple units to accommodate different serving needs, such as presenting bottles and preparing drinks.

Innovation Solution

A beverage serving trolley with a modular design featuring a supporting structure, a handle, wheels, and a removable presentation basket that can be easily modified by swapping out accessories and baskets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If beverage serving trolley is equipped with multiple accessories for different serving needs, then versatility is improved, but device complexity and cluttered appearance worsen

Engineering Contradiction:
Improveserving capabilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The beverage serving trolley is divided into a permanent base structure and separate removable accessories. The base structure includes the trolley frame, wheels, and handle, while accessories such as the presentation basket, ice bucket, and bottle holders are detachable components that can be added or removed as needed, allowing versatility without permanent complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base trolley structure is designed with universal mounting features that can accommodate multiple different types of accessories. The supporting structure includes attachment points and interfaces that work with various accessory types, enabling one trolley to serve multiple functions through accessory swaps rather than requiring multiple specialized trolleys

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If beverage serving trolley is specifically equipped for particular occasions, then serving precision is improved, but adaptability to other occasions worsens

Engineering Contradiction:
Improveserving configurationVSAvoidreconfiguration capability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The trolley configuration is made dynamic through removable and reconfigurable accessories. Instead of fixed arrangements optimized for specific occasions, the accessories can be added, removed, and repositioned to match different serving requirements, allowing the same base structure to adapt to various occasions with precise configuration for each use

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If presentation basket is permanently fixed to trolley, then structural stability is improved, but ease of modification worsens

Engineering Contradiction:
Improvestructural stabilityVSAvoidmodification ease
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The presentation basket is extracted from the permanent structure and designed as a removable accessory. It connects to the trolley through detachable mounting mechanisms such as clips, slots, or friction-fit interfaces, allowing the basket to remain stable during use while enabling easy removal and replacement without permanent attachment or complex assembly procedures

Inventive Principle:
Principle #2Taking out (Extraction)
