Solution Overview

Problem

Existing cooker hoods lack variety in lighting modes, with direct and harsh light emission causing discomfort and uneven distribution, leading to inadequate illumination and atmosphere creation in cooking areas.

Innovation Solution

Incorporating a light reflection member, such as a reflective structural member or layer, attached to the cooker hood's components, which reflects light emitted by the lighting apparatus to prevent direct eye exposure and enhance even distribution, allowing for adjustable brightness and atmosphere creation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If direct light projection is used, then lighting simplicity is maintained, but light comfort and even distribution deteriorate

Engineering Contradiction:
Improvelighting structure complexityVSAvoidlight distribution evenness
Core Design Contradiction:
Device complexityVSIllumination intensity

Solution Approach 1:

A light reflection member (reflective plate or reflective bead layer) is introduced as an intermediary between the lighting apparatus and the cooking area. This mediator redirects and diffuses the light, achieving even distribution without requiring complex multi-source lighting structures.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The reflective surface properties are optimized to alter light direction and distribution characteristics, transforming direct harsh light into soft, evenly distributed illumination through reflective angle control.

Inventive Principle:
Principle #32Color changes

2Device complexity

If direct light emission is used, then lighting apparatus simplicity is maintained, but eye comfort deteriorates

Engineering Contradiction:
Improvelighting apparatus structureVSAvoiddirect light to eyes
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The light reflection member serves as a mediator that intercepts direct light from the lighting apparatus and redirects it away from direct eye exposure paths, eliminating glare and discomfort while maintaining the simple lighting apparatus structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of directing light downward toward the cooking area directly, the system inverts the approach by having light reflect off a surface at controlled angles, redirecting illumination paths away from user eye levels.

Inventive Principle:
Principle #13The other way round (Inversion)

3Device complexity

If single lighting mode is used, then device simplicity is maintained, but lighting versatility deteriorates

Engineering Contradiction:
Improvelighting control systemVSAvoidlighting mode variety
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The lighting system incorporates adjustable brightness levels and multiple lighting modes (illumination mode, atmosphere mode, dimming mode) that can be dynamically switched, providing versatility without requiring multiple separate lighting apparatus.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A single lighting apparatus is designed to serve multiple functions through the light reflection member's ability to create different lighting effects (direct illumination, ambient atmosphere, dimmed lighting) based on control settings.

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