Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional copper/brass soldered construction or CAB aluminum core construction is used, then manufacturing consistency and material durability are improved, but core size is limited to about 48 inches square and labor requirements increase

Engineering Contradiction:
Improvecore size consistencyVSAvoidlabor requirements
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The intercooler core is divided into multiple modular blocks, each block being a manageable size that can be manufactured with consistent precision using traditional methods. These blocks are then assembled together to form larger intercoolers, eliminating the need to manufacture entire large cores in one piece while maintaining manufacturing consistency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple modular core blocks are combined through assembly to create larger intercooler units. This merging approach allows the system to achieve large core sizes without requiring large-scale manufacturing equipment or excessive labor, as each block is manufactured independently and then joined together.

Inventive Principle:
Principle #5Merging (Combining)

2Area of stationary object

If traditional manufacturing methods are used to create large intercoolers, then core size can be increased, but manufacturing complexity and labor intensity increase significantly

Engineering Contradiction:
Improveintercooler core areaVSAvoidmanufacturing complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The large intercooler core area is achieved by segmenting the core into multiple standardized modular blocks. Each block has a manageable manufacturing complexity, and the overall large area is obtained by assembling these segments together, avoiding the complexity of manufacturing a single large core.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular block design creates universal components that can be used in various intercooler configurations. The same basic block design can be assembled in different arrangements to create intercoolers of various sizes and shapes, reducing manufacturing complexity through standardization.

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

3Reliability

If traditional manufacturing methods are used, then material costs (copper/brass) provide durability, but material costs and weight increase

Engineering Contradiction:
Improvematerial durabilityVSAvoidintercooler weight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The intercooler employs composite construction combining aluminum core blocks with copper/brass fittings and connectors. The aluminum provides lightweight structure while the copper/brass components provide durable connection points, achieving both weight reduction and maintained reliability through material composition rather than pure material selection.

Inventive Principle:
Principle #40Composite materials

AI summary

An apparatus and a method are provided for a modular intercooler block that may be fabricated by way of direct metal printing and assembled to form larger intercoolers. The modular intercooler block comprises cooling fins that are spaced between first and second core headers to allow passage of an airstream. Countersunk holes are arranged on the first and second core headers and configured to receive grommets when the first or second core header is fastened to another core header comprising similarly arranged countersunk holes. A core tube extends along an undulating path from each countersunk hole in the first core header, through the multiplicity of cooling fins, to a similar countersunk hole in the second core header. The core tubes may include thin copper walls and spiraled inner passages to enhance heat transfer to the airstream passing through the multiplicity of cooling fins.
