Solution Overview

Problem

Existing cooking hobs with fixed fastening points lack flexibility to accommodate different geometric conditions, limiting the use of heating elements across various cooking hob designs and platforms.

Innovation Solution

A fastening system with moveable hook elements and snap-in mechanisms allows the heating element to be fixed in arbitrary positions along its circumference, enabling adaptation to diverse cooking hob geometries through connection to a support structure via gluing, screwing, or snapping, and incorporating electric connectors for secure and versatile installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed fastening points are used at predetermined positions, then the heating element can be securely fastened to the cooking hob, but the heating element cannot be adapted to different geometric conditions or cooking hob designs

Engineering Contradiction:
Improveadaptability to different geometric conditionsVSAvoidfastening system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the fastening system movable and adjustable rather than fixed. The fastening elements can be positioned at different locations along the heating element's circumference, allowing adaptation to various geometric conditions and cooking hob designs while maintaining secure fastening capability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements universality by designing a fastening system that can serve multiple cooking hob configurations and geometric conditions. The same heating element with movable fastening points can be adapted to different cooking hob platforms, eliminating the need for multiple specialized fastening systems

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

2Adaptability or versatility

If the heating element is designed for a specific cooking hob platform, then it can be securely installed, but it cannot be used in other cooking hobs or platforms with different designs

Engineering Contradiction:
Improvereusability across different cooking hobsVSAvoidinstallation flexibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The fastening system incorporates movable fastening elements that can be repositioned along the heating element, enabling the same heating element to be installed on different cooking hob platforms with varying geometric requirements while maintaining ease of installation through the adjustable mechanism

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If predetermined fixed fastening elements are used, then the assembly process is simple, but the heating element cannot be adapted to special geometric conditions

Engineering Contradiction:
Improvegeometric adaptabilityVSAvoidadjustment time during assembly
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The movable fastening system allows quick repositioning during assembly to accommodate special geometric conditions, and the snap-in mechanism enables rapid securing once the desired position is reached, minimizing adjustment time while achieving geometric adaptability

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If the fastening system allows arbitrary positioning, then it can adapt to diverse cooking hob geometries, but the fastening mechanism becomes more complex

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidfastening mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fastening mechanism uses movable elements with snap-in capability that can be positioned arbitrarily along the heating element, providing positioning flexibility while the snap-in mechanism itself remains relatively simple in design

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The snap-in mechanism acts as an intermediary that simplifies the arbitrary positioning process by providing discrete, easily engageable positions along the heating element, reducing the complexity of continuous arbitrary positioning while maintaining adaptability

Inventive Principle:
Principle #24Intermediary (Mediator)
