Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional base module assembly is used, then the structure is simple and manufacturing is straightforward, but it is inflexible and costly to adapt to different heat exchanger variants

Engineering Contradiction:
Improveadaptability to different heat exchanger variantsVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base module is divided into two functional parts: a removable insert element and a stationary base module body. The insert element contains the condensate collection basin and can be easily removed or replaced, while the base module body remains fixed. This segmentation allows different insert elements to be used with different heat exchanger variants without redesigning the entire base module structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base module body is designed as a universal platform that can accommodate multiple types of heat exchangers through the use of different insert elements. The standardized interface and mounting structure allow the same base module body to work with various evaporator dimensions and drainage configurations, reducing the need for multiple specialized base module designs.

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

2Loss of energy

If conventional materials are used in the base module, then manufacturing costs are low, but thermal insulation effect is insufficient leading to energy losses

Engineering Contradiction:
Improveheat lossesVSAvoidmanufacturing complexity
Core Design Contradiction:
Loss of energyVSEase of manufacture

Solution Approach 1:

The insert element is constructed using composite materials, specifically a thermally insulating foam core surrounded by a metallic outer shell. The foam material provides excellent thermal insulation properties to minimize heat losses from the condensate collection basin, while the metallic shell provides structural integrity and condensation resistance. This composite structure achieves superior thermal performance without significantly complicating the manufacturing process.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If the condensate collection basin is made as a single integrated piece, then manufacturing is simpler, but adaptability to different evaporator dimensions is reduced

Engineering Contradiction:
Improveadaptability to different evaporator dimensionsVSAvoidmanufacturing simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The condensate collection system is segmented into the removable insert element that can be tailored to specific evaporator dimensions, while the base module body remains standardized. This allows the condensate collection basin to be optimized for different evaporator sizes and drainage requirements without redesigning the entire base module.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert element is designed to be dynamically removable and replaceable, allowing the system to adapt to different operational requirements and heat exchanger variants. The insert element can be easily taken out and replaced with another insert element of different dimensions or drainage configuration, providing flexibility without permanent modifications to the base module structure.

Inventive Principle:
Principle #15Dynamics
