Solution Overview

Problem

The scattered arrangement of valve components in air-conditioning water systems leads to inconvenient on-site installation and operation, failing to meet practical needs.

Innovation Solution

A water tank module integrating a first buffer water tank with a first ball valve on the leaving water pipe and a second buffer water tank with a second ball valve, safety valve, exhaust valve, and water replenishment valve on the return water pipe, along with a bypass pipe and bypass valve, to facilitate efficient installation and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If valve components are scattered arranged in various parts of the air-conditioning water system, then each component can be independently installed and maintained, but the on-site installation and operation become inconvenient and complex

Engineering Contradiction:
Improveconvenience of on-site installation and operationVSAvoidscattered arrangement of valve components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple valve components (first ball valve, second ball valve, bypass valve, safety valve, exhaust valve, and water replenishment valve) that were previously scattered throughout the system into a single integrated water tank module. This merging of components resolves the technical contradiction by improving ease of operation through centralized access while managing device complexity through modular design that allows the integrated unit to be installed as a single component.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If multiple valve components are integrated into a single water tank module, then on-site installation and operation become convenient, but the device structure becomes more complex

Engineering Contradiction:
Improveconvenience of on-site installationVSAvoidintegrated water tank module structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The water tank module is designed as a multi-functional universal unit that houses multiple valve components (first ball valve for leaving water pipe, second ball valve for return water pipe, bypass valve, safety valve, exhaust valve, and water replenishment valve) within a single integrated structure. This multi-functionality approach resolves the contradiction by consolidating numerous separate components into one universal module, improving installation convenience while the modular design manages structural complexity through standardized integration.

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

3Productivity

If valve components are arranged scattered in the system, then the system layout is flexible, but the installation time and operational efficiency are reduced

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidon-site installation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent merges multiple separately arranged valve components into a single integrated water tank module, transforming the installation process from installing multiple discrete components to installing one consolidated unit. This merging directly addresses the productivity contradiction by significantly reducing on-site installation time and improving installation efficiency, as the integrated module requires fewer connection points and less complex routing than scattered components.

Inventive Principle:
Principle #5Merging (Combining)
