Solution Overview

Problem

Existing stage light fixtures face issues with rainwater ingress through air inlets and outlets, leading to damage from short-circuiting and rusting, while also failing to provide effective heat dissipation.

Innovation Solution

A waterproof ventilation module with staggered air vents and water blocking baffles that prevent rainwater entry while maintaining airflow, using anti-dust nets and additional water blocking features to ensure both waterproofing and ventilation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If air inlet and air outlet are provided for heat dissipation, then heat dissipation effectiveness is improved, but rainwater ingress occurs causing damage to elements

Engineering Contradiction:

Improveheat dissipation effectivenessVSAvoidrainwater ingress

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The air inlet and air outlet are segmented into separate components with distinct functions. The air inlet includes a water blocking baffle that segments the opening into a vent portion for airflow and a water blocking portion for rain protection. The air outlet has a separate water blocking structure, creating multiple segmented barriers against rainwater while maintaining ventilation pathways.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Water blocking baffles and water blocking structures serve as intermediary elements between the external environment and the internal cavity. These intermediaries allow air to pass through while blocking rainwater, acting as a mediator that selectively permits airflow while preventing water ingress through the ventilation openings.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If air vents are provided on housing, then ventilation function is improved, but rainwater can enter through vents causing short-circuiting and rusting

Engineering Contradiction:

Improveventilation functionVSAvoidprotection from moisture

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

Each air vent is segmented into functional zones: a vent portion for airflow and a water blocking portion with baffles or structures that prevent rainwater entry. The segmentation creates multiple pathways for air while blocking water through geometric design of the vent structures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the air vent structure have different local qualities - the vent portion is open for airflow while the water blocking portion has protruding baffles or structures that create water barriers. This local differentiation allows the same structure to provide both ventilation and waterproofing functions.

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If water blocking baffles are added to prevent rainwater entry, then waterproof performance is improved, but device complexity increases

Engineering Contradiction:

Improvewaterproof performanceVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The water blocking baffles are designed to perform multiple functions: blocking rainwater entry, guiding airflow through the vent, and structurally supporting the air inlet assembly. The air inlet structure itself serves both as a mounting structure and as part of the water blocking system, reducing the need for separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The water blocking baffle is merged with the air inlet structure, forming an integrated assembly where the baffle is positioned within or as part of the air inlet housing. This merging reduces the number of separate parts and simplifies assembly while maintaining both ventilation and waterproofing functions.

Inventive Principle:

Principle #5Merging (Combining)
