Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a recessed section is incorporated into the frame to install lighting devices, then lighting functionality is improved, but the structure becomes complex

Engineering Contradiction:
Improvelighting functionalityVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lighting module is extracted as a separate, self-contained unit that can be installed in the frame without requiring a recessed section. The lighting module includes a lighting element, a reflective element, and a support structure that holds all components together, eliminating the need to modify the frame structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Multiple functional elements (lighting element, reflective element, support structure) are merged into a single integrated lighting module. This combination allows the module to function as a complete lighting unit that can be easily installed and removed without affecting the overall extractor hood structure.

Inventive Principle:
Principle #5Merging (Combining)

2Illumination intensity

If a specific lighting configuration is used in the extractor hood, then lighting performance is improved, but the extractor hood is limited to a single type of lighting

Engineering Contradiction:
Improvelighting performanceVSAvoidlighting type
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The lighting module is designed with adjustable components that allow the lighting configuration to be dynamically changed. The support structure can be positioned at different locations within the frame, and the reflective element can be oriented at different angles, enabling the same module to provide various lighting patterns and intensities.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The lighting module is designed as a universal component that can be used in different extractor hood configurations and can provide multiple lighting functions. The same module can be installed in different positions and orientations to achieve different lighting effects, making it adaptable to various cooking zones and hood designs.

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

3Illumination intensity

If lighting elements are arranged above a flat frame element, then light distribution is improved, but the lighting type is limited

Engineering Contradiction:
Improvelight distributionVSAvoidlighting type
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

A reflective element is introduced as an intermediary between the lighting element and the cooking zone. This reflective element redirects and distributes light in multiple directions, improving light distribution while allowing the use of different types of lighting elements (LED, halogen, fluorescent) without changing the basic mounting structure.

Inventive Principle:
Principle #24Intermediary (Mediator)
