Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If glass-ceramic worktops with integrated electronic components are assembled using traditional embedding or gluing methods, then the components are securely fixed, but the assembly and disassembly require specific tools and are difficult, especially for large plates

Engineering Contradiction:
Improveease of disassemblyVSAvoidassembly complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical embedding or gluing methods with magnetic attraction. The magnetic connection element with thickness less than 10 cm contains magnetic parts that attract and hold electronic components without requiring mechanical fasteners or adhesives, enabling tool-free assembly and disassembly while maintaining secure fixation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnetic connection element as an intermediary component between the glass-ceramic worktop and electronic components. This intermediate layer with thickness less than 10 cm provides the magnetic field necessary for attraction, facilitating easy attachment and detachment of components without direct mechanical or chemical bonding

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If glass-ceramic plates are made large to serve as work surfaces, then the surface area is sufficient, but the weight becomes significant and prevents easy handling

Engineering Contradiction:
Improvework surface areaVSAvoidease of handling
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent divides the glass-ceramic worktop system into separable components: the worktop plate itself and detachable electronic components. The magnetic connection element with thickness less than 10 cm enables these components to be easily separated and reattached, allowing the heavy worktop to remain stationary while lighter components can be moved independently for handling and maintenance

Inventive Principle:
Principle #1Segmentation

3Reliability

If electronic components are embedded in the glass-ceramic plate, then they are securely fixed, but the position and choice of accessories are fixed in advance and cannot be changed

Engineering Contradiction:
Improvecomponent fixationVSAvoidaccessory configurability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transitions from static embedded components to dynamically reconfigurable components using magnetic attraction. The magnetic connection element with thickness less than 10 cm allows electronic components to be easily attached, detached, and repositioned, enabling the worktop to adapt to different configurations and uses while maintaining secure fixation during operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent creates a universal mounting system using the magnetic connection element that can accommodate different types of electronic components and accessories. The magnetic attraction mechanism works with various component types, allowing the worktop to serve multiple functions and be customized according to different needs without requiring re-engineering of the base structure

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