Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If air deflection devices with heat exchanger fins are arranged in corner areas of air ducts, then cooling effect is achieved, but installation complexity and effort increase significantly

Engineering Contradiction:
Improveair temperature in ductVSAvoidinstallation complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The air deflection device is divided into multiple segments that can be installed separately in the air duct corner. Each segment contains a portion of the fins and can be assembled step-by-step, transforming a single complex installation into multiple simpler steps. This segmentation allows the cooling function to be maintained while significantly reducing installation complexity and effort.

Inventive Principle:
Principle #1Segmentation

2Temperature

If fins are designed to extend completely over the air duct cross section, then cooling efficiency is maximized, but installation space requirements and structural complexity increase

Engineering Contradiction:
Improvecooling efficiencyVSAvoidinstallation space
Core Design Contradiction:
TemperatureVSVolume of stationary object

Solution Approach 1:

Instead of using a single large fin structure that would occupy the entire air duct cross-section, the fins are divided into multiple smaller segments arranged in series. This segmentation allows the cooling surface area to be maintained (achieving good cooling efficiency) while each individual segment occupies less space, making the overall installation more compact and manageable within the air duct corner area.

Inventive Principle:
Principle #1Segmentation

3Temperature

If multiple segments with separate inlet pipes are used for fluid supply, then cooling coverage is improved, but device complexity increases

Engineering Contradiction:
Improvecooling coverageVSAvoidfluid supply complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The fluid supply system is segmented to match the physical segmentation of the air deflection device. Each segment has its own inlet pipe connection point, allowing independent fluid supply to each section. This segmentation improves cooling coverage by ensuring all fin surfaces receive adequate coolant flow, while the modular nature of the segments makes the overall system easier to install and maintain compared to a single complex distribution system.

Inventive Principle:
Principle #1Segmentation
