Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate air heating apparatus and hot water heating apparatus are used, then heating function and hot water function can be provided, but installation costs increase and space for installation is required

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the air heating apparatus and hot water heating apparatus into a single integrated system. The heating water supply flow path is coupled with the hot water heating flow path, allowing one apparatus to perform both air heating and hot water heating functions, thereby reducing installation costs and space requirements

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heating apparatus is designed with multi-functionality to perform both air heating and hot water heating operations. By integrating the hot water heating flow path into the heating water supply flow path, the system can simultaneously or alternatively provide both heating functions through a single apparatus

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

2Device complexity

If both heating function and hot water function are provided through integrated system, then space utilization is improved and costs are reduced, but heating performance and hot water temperature do not reach target values

Engineering Contradiction:

Solution Approach 1:

The patent employs dynamic control of flow rates through valves to optimize heating performance. The controller adjusts the flow rates of heating water through the heat exchanger and hot water through the hot water heating flow path based on operational requirements, enabling the system to maintain target temperatures for both air heating and hot water heating

Inventive Principle:

Solution Approach 2:

The system changes operational parameters (flow rates, valve opening degrees) to optimize performance. By dynamically adjusting the flow rates of heating water and hot water through different flow paths, the system achieves target temperatures for both heating functions simultaneously

Inventive Principle:
Principle #35Parameter changes

3Productivity

If both indoor heating operation and hot water heating operation are performed simultaneously, then efficiency is increased, but temperature control becomes more difficult

Engineering Contradiction:
ImproveefficiencyVSAvoidtemperature control
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements feedback control where the controller monitors temperatures and flow rates, and adjusts valve opening degrees accordingly. This feedback mechanism enables the system to maintain target temperatures for both air heating and hot water heating even when operating simultaneously, simplifying temperature control

Inventive Principle:
Principle #23Feedback
