Solution Overview

Problem

Existing electroplating systems face challenges in thoroughly renewing and cleaning the air inside the housing of transport trolleys, leading to incomplete pollutant removal and potential accumulation, which can result in harmful concentrations and increased energy consumption for ventilation systems.

Innovation Solution

The electroplating system incorporates an air cleaner that continuously cleans the air within the housing using a fan to convey and clean the air using methods such as droplet separators or air washers, allowing for immediate pollutant capture at the source and reducing the need for extensive room air renewal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If room air is blown into the housing and edge suction is intensified to remove pollutants, then pollutant removal is improved, but energy consumption increases and pollutants are discharged into room air

Engineering Contradiction:
Improvepollutant concentration in room airVSAvoidenergy consumption of ventilation system
Core Design Contradiction:
Object-generated harmful factorsVSLoss of energy

Solution Approach 1:

The invention extracts and removes pollutants directly from the housing interior using a dedicated suction device connected to an exhaust system. This separates the pollutant removal function from the room ventilation system, allowing targeted extraction at the source without the need to blow large volumes of room air into the housing or intensify general edge suction, thereby reducing energy consumption while effectively removing pollutants.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention introduces an intermediary pollutant removal system (housing-specific suction device and exhaust system) between the pollutant source (electroplating bath) and the room air. This intermediary system captures pollutants before they can disperse into the room, eliminating the need for high-energy room air circulation and intensive edge suction while maintaining low pollutant concentrations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-generated harmful factors

If air exchange in the housing is performed only when the carriage is in a station, then the system is simple, but pollutant removal is incomplete and accumulation occurs

Engineering Contradiction:
Improvepollutant accumulation in housingVSAvoidcomplexity of air cleaning system
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The invention implements continuous air cleaning by operating the suction device and exhaust system throughout the entire transport cycle, not just when the carriage is stationary at a station. This continuous operation ensures pollutants are constantly removed from the housing interior, preventing accumulation while the system remains relatively simple in design.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The invention performs preliminary pollutant removal by continuously extracting contaminants as they are generated during transport, rather than waiting until the carriage reaches a station. This preliminary and ongoing action prevents pollutant accumulation throughout the transport process, maintaining air quality without requiring complex intermittent cleaning mechanisms.

Inventive Principle:
Principle #10Preliminary action

3Loss of substance

If the housing is completely closed off at the bottom with drip trays, then liquid containment is improved, but pollutant escape into room air increases during transport

Engineering Contradiction:
Improveliquid dripping into other bathsVSAvoidpollutant release into room air
Core Design Contradiction:
Loss of substanceVSObject-generated harmful factors

Solution Approach 1:

The invention introduces an intermediary exhaust system that captures pollutants at the source (housing interior) before they can escape through the bottom opening during transport. The suction device creates a controlled airflow that prevents uncontrolled pollutant release, while the drip tray continues to contain liquid effectively. This intermediary system resolves the conflict between liquid containment and pollutant control.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention extracts pollutants from the housing interior through the suction device and exhaust system, removing them before they can escape into the room air through the bottom opening. This extraction mechanism allows the housing to remain effectively closed for liquid containment while simultaneously preventing pollutant escape during transport.

Inventive Principle:
Principle #2Taking out (Extraction)

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

This solution enables continuous air cleaning, reducing pollutant concentrations and energy consumption by capturing pollutants as they are released, minimizing their dispersal into the room air and optimizing the transport process by allowing slower transport speeds and reducing the size and energy requirements of ventilation systems.
