Solution Overview

Problem

Conventional evaporative systems for air conditioning systems face challenges in mounting the hydraulic device within the air duct without obstructing airflow and compliance with market regulations, leading to reduced energy efficacy and limited flexibility in installation.

Innovation Solution

An integrated hydraulic device with a housing, water tank, and individually controllable pumps is designed, allowing for internal or external mounting, minimizing airflow obstruction, and enabling precise water supply adjustment based on humidity and temperature sensors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the hydraulic device is mounted inside the air duct, then the system is compact and easy to install, but the air flow is obstructed leading to reduced energy efficacy

Engineering Contradiction:
Improveinstallation easeVSAvoidenergy efficacy
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The hydraulic device is extracted from the air duct interior and mounted externally on the air duct surface. This extraction eliminates the air flow obstruction problem while maintaining the compact installation advantage, as the device can be attached to the exterior of the air duct without interfering with the internal air flow path.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of energy

If the hydraulic device is mounted outside the air duct, then air flow is not obstructed and energy efficacy is maintained, but access limitations and legislation may prevent mounting

Engineering Contradiction:
Improveenergy efficacyVSAvoidinstallation flexibility
Core Design Contradiction:
Loss of energyVSAdaptability or versatility

Solution Approach 1:

The mounting system is designed to be universal, accommodating both internal and external mounting configurations. The hydraulic device includes standardized mounting interfaces and connection mechanisms that allow it to be installed on the air duct exterior while maintaining full functionality, thereby satisfying both energy efficiency requirements and various market regulations or access limitations.

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

3Quantity of substance

If conventional hydraulic devices with separate components are used, then water supply can be provided to material banks, but the device complexity increases and individual adjustment is not possible

Engineering Contradiction:
Improvewater supplyVSAvoidhydraulic device complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The pump and outlet valve are merged into a single integrated unit, eliminating the need for separate components and complex interconnections. This integration maintains the water supply function to material banks while significantly reducing device complexity. The unified design also enables individual adjustment capabilities through integrated control mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated pump-valve unit incorporates individually adjustable outlet valves for each material bank, enabling dynamic control of water flow distribution. This allows the system to adapt water supply rates to specific needs of different material banks while maintaining a simple overall device structure.

Inventive Principle:
Principle #15Dynamics
