Solution Overview

Problem

Existing coolant heating modules for vehicles require numerous components for connection, leading to increased costs and reduced electric vehicle efficiency due to increased weight and complexity.

Innovation Solution

An integrated coolant heating module where a water pump and multi-way valve are directly coupled to the water heater's mounting parts, eliminating the need for separate connecting members, and a water-cooled condenser is directly connected to the water heater with a detachable coupling part, promoting modularization and reduced component count.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a water heater, water pump, and multi-way valve are integrally modularized with separate connecting members (base bracket, fluid pump fixing bracket, channel switching valve fixing bracket, and fastening bolts), then the components can be mechanically connected, but the number of components increases leading to increased cost and weight

Engineering Contradiction:
Improvemodularization capabilityVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the water heater body with the mounting brackets by integrally forming the base bracket, fluid pump fixing bracket, and channel switching valve fixing bracket as single structural units with the water heater body. This eliminates the need for separate connecting members and fastening bolts, thereby reducing the total number of components while maintaining modularization capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The water heater body is designed to serve multiple functions: it acts as both the heating element container and as the mounting structure for the water pump and multi-way valve. The integrally formed brackets provide both structural support and mounting functionality, reducing the need for dedicated connecting components.

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

2Reliability

If multiple separate connecting members and fastening bolts are used to assemble the coolant heating module, then the components can be securely connected, but the weight of the module increases reducing electric vehicle efficiency

Engineering Contradiction:
Improveconnection stabilityVSAvoidmodule weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

By integrating the mounting brackets into the water heater body as single structural units, the patent eliminates multiple separate connecting members and fastening bolts. This merging of functions reduces the overall weight of the module while maintaining secure connections through the integrally formed structure.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If a water heater, water pump, and multi-way valve are integrally modularized with separate connecting members, then the components can be mechanically connected, but the cost of the module increases

Engineering Contradiction:
Improvemodularization capabilityVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent reduces manufacturing cost by merging the water heater body with the mounting brackets into integrally formed structures. This eliminates the need to manufacture and assemble multiple separate connecting members and fastening bolts, thereby reducing both component count and manufacturing complexity.

Inventive Principle:
Principle #5Merging (Combining)

4Device complexity

If the water heater and water-cooled condenser are permanently connected, then the structure is simplified, but the module lacks adaptability for different configurations

Engineering Contradiction:
Improvestructural simplicityVSAvoidassembly flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements a detachable coupling mechanism between the water heater and water-cooled condenser, allowing the connection to be dynamically adjusted. The coupling part can be connected or disconnected as needed, providing both structural simplicity when connected and assembly flexibility when detachment is required, thus achieving adaptability for different configurations.

Inventive Principle:
Principle #15Dynamics
