Solution Overview

Problem

Existing food serving stations often have disorganized appliance arrangements, lacking a professional appearance and requiring different appliances for various food preparation tasks throughout the day.

Innovation Solution

A modular food preparation apparatus with interchangeable appliance modules and a base unit that supports modules with adjustable positioning, allowing for cooking and holding functions, and includes a breath guard for aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple different appliances are provided at the employee side for preparing different types of food, then the food preparation capabilities are improved, but the arrangement becomes disorganized and lacks professional appearance

Engineering Contradiction:
Improvefood preparation capabilitiesVSAvoidarrangement organization
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The food service system is divided into separate, interchangeable appliance modules (coffee module, tea module, hot water module, etc.) that can be independently selected and positioned. Each module is a self-contained unit with standardized interfaces, allowing the employee side to be segmented into functional sections rather than a cluttered arrangement of different appliances.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The customer side counter is designed with universal receptacles that can accommodate multiple types of appliance modules through standardized docking interfaces. A single counter structure serves multiple functions by receiving different modules (coffee, tea, hot water, etc.), creating an organized yet versatile arrangement that maintains professional appearance while providing diverse food preparation capabilities.

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

2Adaptability or versatility

If different appliances are arranged for different food preparation tasks throughout the day, then the operational flexibility is improved, but the device complexity and space requirements increase

Engineering Contradiction:
Improveoperational flexibilityVSAvoidspace requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The appliance modules are designed to be dynamically reconfigurable on the customer side counter. Modules can be easily docked, undocked, and repositioned along the counter according to daily operational needs. The standardized interfaces and mobile cart design enable dynamic adjustment of the appliance arrangement without requiring complex installation or significant space reconfiguration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Multiple appliance modules are arranged in a linear nesting pattern along the customer side counter, with each module occupying a standardized segment. The modules can be nested in sequence (coffee module, then tea module, then hot water module, etc.) creating an organized compact arrangement that maximizes space utilization while maintaining access to all functions.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If the food container support surface is positioned at cooking elevation, then the cooking function is improved, but the holding function requires additional space below the surface

Engineering Contradiction:
Improvecooking functionVSAvoidholding space
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The appliance modules utilize vertical space efficiently by incorporating holding receptacles beneath the cooking surface level. The food container support surface maintains cooking elevation for ease of operation, while the holding function is implemented in the vertical dimension below the surface through integrated receptacles within each module, eliminating the need for additional horizontal space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Food preparation apparatus and associated appliance modules and methods. Appliances modules can be selectively docked at docks of an appliance interface of a base. An appliance module includes a food container support surface movable between cooking and holding positions. An appliance module includes a receptacle having a holding well that can be selectively configured in a generally horizontal position or an inclined position.
