Solution Overview

Problem

Traditional aircraft trolleys take time to transport hot food and beverages from the galley to passengers, causing items to cool before all passengers can receive them at an optimal temperature.

Innovation Solution

A portable insert for an aircraft galley, equipped with an energy storage, a receiving portion, and a heater, allowing for on-demand heating of food and beverages when removed from the galley, maintaining higher temperatures for longer periods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If food and beverages are transported using traditional trolleys from the galley to passengers, then the transport process is simple and equipment is minimal, but the food and beverages cool down before all passengers can receive them at an optimal temperature

Engineering Contradiction:
Improvefood temperatureVSAvoidtransport time
Core Design Contradiction:
TemperatureVSLoss of time

Solution Approach 1:

The heating function is extracted from the stationary galley and integrated into a portable insert that can be removed and moved to passengers. This allows the heating capability to follow the food service process, maintaining temperature during transport and service without requiring the entire galley system to be mobile.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The insert transitions from a stationary heating device in the galley to a mobile unit that can be positioned dynamically throughout the aircraft cabin. This dynamic positioning allows continuous heating close to passengers, eliminating the temperature loss that occurs during static transport via trolley.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If food and beverages are kept hot using traditional galley equipment, then the heating capacity is sufficient, but the equipment is stationary and cannot serve passengers directly in their seats

Engineering Contradiction:
Improveservice convenienceVSAvoidequipment structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The galley heating system is segmented into a removable portable insert that contains the essential heating components (energy storage, heater, control). This segmented design separates the mobile service function from the stationary galley infrastructure, enabling direct service to passengers while keeping the overall system manageable in complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The portable insert serves multiple functions: it acts as a heating device, a transport container, and a direct service unit that can be positioned at passenger seats. This multi-functionality consolidates several operations into one device, improving service convenience without proportionally increasing complexity.

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

3Loss of substance

If food is prepared in large quantities in the galley for all passengers, then the preparation process is efficient, but unused food must be discarded causing waste

Engineering Contradiction:
Improvefood wasteVSAvoidfood preparation efficiency
Core Design Contradiction:
Loss of substanceVSProductivity

Solution Approach 1:

Food is partially prepared in the galley and then transferred to the portable insert for final heating and serving. This preliminary preparation allows flexibility in timing and quantity, enabling staff to heat and serve only the amount needed based on actual passenger demand, thereby reducing food waste while maintaining preparation efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The portable insert enables a form of self-service where food can be heated on-demand at passenger seats according to individual requests. This on-demand heating capability eliminates the need to pre-heat and transport large quantities of food that may not be consumed, reducing waste while maintaining efficient use of kitchen resources.

Inventive Principle:
Principle #25Self-service
