Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex bypass components and control members are added to control oil flow, then oil temperature control reliability is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveoil temperature control reliabilityVSAvoidduct layout complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the bypass function and temperature control function into a single integrated plate heat exchanger assembly. The control member is integrated directly into the heat exchanger structure, eliminating the need for separate bypass components and complex duct layouts. This merging of functions reduces device complexity while maintaining reliable temperature control through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If complex duct layouts with control members are used, then oil temperature control precision is improved, but production and realization costs increase

Engineering Contradiction:
Improvetemperature control precisionVSAvoidproduction cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent segments the oil flow path into parallel channels within the plate heat exchanger, allowing precise control of oil flow distribution. The control member is designed as a simple adjustable component that can be easily manufactured and installed. This segmentation approach enables precise temperature control without requiring complex overall duct layouts, thereby reducing manufacturing costs.

Inventive Principle:
Principle #1Segmentation

3Volume of moving object

If compact oil temperature control assembly is designed, then space utilization in vehicle is improved, but device complexity may increase

Engineering Contradiction:
Improveassembly volumeVSAvoidgeometry complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent employs a nested structure where the control member is housed within the plate heat exchanger assembly itself. The bypass channels are integrated within the same compact volume as the heat exchange channels. This nesting approach achieves compact assembly dimensions suitable for vehicle installations while maintaining functional complexity only at the component level, not at the overall assembly level.

Inventive Principle:
Principle #7Nested doll (Nesting)
