1Reliability

If a window-shade radiator is configured at the air outlet to block light and exhaust air, then light blocking and ventilation functions are achieved, but the structure and manufacturing process become complicated and cost increases

Engineering Contradiction:

Improvelight blocking and ventilation effectVSAvoidstructure and manufacturing process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the light-blocking plate and ventilation plate into a single integrated component with unified structure. The light-blocking portions and ventilation openings are formed as one piece through die-cutting, eliminating the need for separate frame and blade components that need to be assembled, thus simplifying both structure and manufacturing process while maintaining effective light blocking and air exhaust functions

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated light-blocking and ventilation plate serves multiple functions simultaneously: it blocks light from leaking out, allows hot air to exhaust through the ventilation openings, and provides structural support. This multi-functional design replaces the traditional window-shade radiator that required separate components for each function, reducing device complexity and manufacturing cost

Inventive Principle:

Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution provides effective light blocking and ventilation with reduced assembly time and production costs, ensuring efficient heat dissipation and preventing light leakage while maintaining a stable environment for the light source.

Implementation Method 1

An air outlet is provided in the closed space of the light source chamber, so that hot air flow in the light source chamber flows outside of the light fixture body through the air outlet

Methodology Applied

Scientific EffectConvection: Convection

Implementation Method 2

Vertical projection of the light-blocking plate on the ventilation plate overlaps the air vents, so that the light-blocking plate can prevent light from leaking out of the air vent

Methodology Applied

Scientific EffectLight blocking: Absorption (EM radiation)

AI summary

A simple light-blocking and air-exhausting device includes a ventilation plate and a light-blocking plate arranged oppositely and spaced apart from each other. The ventilation plate is provided with an air vent formed by die-cutting the ventilation plate, and vertical projection of the light-blocking plate on the ventilation plate overlaps the air vent. The vertical projection of the light-blocking plate on the ventilation plate overlaps the air vents on the ventilation plate, so that the light-blocking plate can prevent light from leaking out of the air vents, while air flow can flow out from a gap between the light-blocking plate and the ventilation plate.
