Solution Overview

Problem

Existing dining tables with integrated cooking facilities fail to provide a space-saving, ergonomic, and reliable solution for preparing warm raclette dishes, particularly in the catering and hotel industry, where assembly and disassembly of raclette devices are cumbersome and require significant effort.

Innovation Solution

A dining table with an extendable section that houses a pocket-shaped opening with heating elements, allowing for the heating of multiple raclette scoops or pans, which can be raised or lowered for different usage modes, eliminating the need for separate cooking equipment and reducing assembly/disassembly efforts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a raclette grill is integrated into a dining table, then food heating functionality is provided, but the table structure becomes more complex and requires additional storage space

Engineering Contradiction:
Improvefood heating functionalityVSAvoidtable structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cooking unit is nested within a recess in the tabletop, allowing the heating elements and controls to be stored inside the table structure when not in use. This integrates the raclette grill functionality while maintaining a clean, simple table appearance and eliminating the need for separate storage space.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The tabletop surface serves multiple functions: it acts as both the dining surface and the storage location for the cooking unit. The recess in the tabletop accommodates the cooking unit, allowing the same surface area to fulfill both dining and cooking preparation roles.

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

2Adaptability or versatility

If a raclette grill is set up on a table, then food heating is enabled, but assembly and disassembly require considerable time and effort

Engineering Contradiction:
Improvefood heating capabilityVSAvoidassembly and disassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The cooking unit is permanently integrated into the dining table structure, merging the table and cooking device into a single unified piece of furniture. This eliminates the need for separate assembly and disassembly operations, as the cooking unit is already in place and ready for use.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cooking unit is pre-installed and positioned within the tabletop recess during manufacturing, so that when the table is delivered to the user, the cooking functionality is already prepared and requires no additional setup or assembly steps.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If multiple raclette grills are set up for larger groups, then more food portions can be heated, but the complexity and effort of setup increases significantly

Engineering Contradiction:
Improvenumber of food portionsVSAvoidsetup complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The cooking unit is divided into multiple independent heating zones or stations within the same tabletop recess, allowing simultaneous preparation of multiple food portions. Each heating element can be controlled independently, enabling service for larger groups without requiring multiple separate grill units.

Inventive Principle:
Principle #1Segmentation

4Area of stationary object

If a cooking unit is built into the table, then no additional storage space is needed, but the tabletop design becomes more complex

Engineering Contradiction:
Improvestorage space requirementVSAvoidtabletop design
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The cooking unit is nested within a recess that is integrated into the tabletop structure. This allows the cooking components to be housed within the table itself, eliminating the need for separate storage space while maintaining a streamlined design. The recess is strategically positioned to minimize impact on the overall tabletop aesthetics.

Inventive Principle:
Principle #7Nested doll (Nesting)

5Ease of operation

If the pocket-shaped opening protrudes from the tabletop, then food heating is accessible, but it may cause burn marks on the tabletop

Engineering Contradiction:
Improvefood heating accessibilityVSAvoidburn marks on tabletop
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cooking unit is extracted from the tabletop surface and positioned within a recess, creating a separation between the heating elements and the tabletop surface. This allows the cooking function to be accessible while preventing direct contact between hot containers and the tabletop, eliminating the risk of burn marks.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The recess structure acts as an intermediary between the cooking unit and the tabletop surface. It provides a protective barrier that prevents direct thermal contact between the heated containers and the tabletop material, while still allowing adequate clearance for heat transfer to the food.

Inventive Principle:
Principle #24Intermediary (Mediator)
