Innovation Solution

A modular hob system design featuring a one-piece cooking support with interchangeable energy converters of different output forms, integrated extraction devices, and a user-friendly interface, allowing for customizable configurations that reduce logistical efforts and enhance maintenance, while minimizing gaps and steps for easier cleaning and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple energy converter configurations are produced in stock, then customer requirements can be met, but logistical effort increases and capital is tied up

Engineering Contradiction:
Improveconfiguration variantsVSAvoidlogistical effort
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hob system is segmented into a base unit and interchangeable energy converter modules. Each energy converter is a separate, standalone component that can be independently produced and stored. This segmentation allows the base unit to be produced once in stock, while only the modular energy converters need to be varied to meet different customer requirements, significantly reducing logistical complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base hob unit is designed with universal compatibility to accept different types of energy converter modules (induction, radiant heat, gas, electric mass). This universality allows a single base design to support multiple configuration variants by simply changing the energy converter module, eliminating the need to produce and stock multiple complete hob system variants.

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

2Stability of the object's composition

If energy converters are fixed in position, then structural stability is maintained, but defective modules cannot be easily replaced

Engineering Contradiction:
Improvestructural stabilityVSAvoidmodule replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The fastening device incorporates a release mechanism that allows the energy converter module to be dynamically removed and reinstalled. The module can be securely fixed during operation (stable state) but can be easily released when replacement is needed (transient state). This dynamic capability enables both structural stability during use and easy replacement during maintenance.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple hob configuration variants are produced, then individual customer requirements can be met, but stock production complexity increases

Engineering Contradiction:
Improveindividual adaptationVSAvoidstock production
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The product is segmented into a standardized base unit and varied energy converter modules. The base unit can be produced once in large quantities (economies of scale), while the energy converter modules are produced in smaller batches to match customer demand for specific types (induction, radiant heat, gas, electric mass). This segmentation transforms complex multi-variant stock production into simple modular assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base hob unit serves as a template or copy that can be combined with different energy converter modules to create various configurations. Instead of producing entirely different hob systems for each configuration, the same base design is copied and paired with different modules, simplifying the manufacturing process.

Inventive Principle:
Principle #26Copying
