Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional base unit structure is used for the catalyst device, then the mechanical stability is limited, but the electric energy transmission is improved
Solution Approach 1:
The base unit employs a composite structure combining a foam body with pressed material regions. The foam body provides mechanical stability and structural integrity, while the pressed material regions (with higher density) are strategically positioned at electric connection areas to enhance electric energy transmission. This composite approach resolves the contradiction by integrating two material states with complementary properties within a single component.
Solution Approach 2:
The base unit features non-uniform material distribution with pressed material regions localized at specific connection points. These pressed regions have different density and electrical conductivity properties compared to the surrounding foam body. This local quality variation optimizes both mechanical stability (through the foam structure) and energy transmission (through pressed connection regions) without requiring the entire base unit to be made of a single material type.
2Strength
If the base unit is made of dense material for improved mechanical stability, then the strength is improved, but the weight increases
Solution Approach 1:
The base unit utilizes a foam body with porous structure as its primary material. This foam material provides adequate mechanical stability while significantly reducing the overall weight compared to solid dense materials. The porous structure allows the base unit to maintain structural integrity necessary for supporting catalytically active elements while being lightweight enough for practical installation and energy efficiency.
Solution Approach 2:
The base unit combines foam material (low density) with pressed material regions (higher density) in a composite structure. The foam body constitutes the majority of the base unit volume, providing lightweight structural support, while localized pressed regions provide enhanced mechanical strength at critical connection points. This composite approach achieves the necessary strength-to-weight ratio by strategically placing dense material only where mechanically critical.
3Loss of energy
If the electric energy unit is made larger for improved energy transmission, then the energy transmission is improved, but the device complexity increases
Solution Approach 1:
The electric connection regions are merged with the base unit structure itself rather than being separate components. The pressed material regions are integrated directly into the foam body of the base unit, creating a unified structure that serves both mechanical and electrical functions. This merging eliminates the need for separate electric energy transmission components, reducing device complexity while maintaining effective energy transmission.
Solution Approach 2:
The base unit serves multiple functions simultaneously: it provides mechanical support for catalytically active elements, maintains structural stability, and acts as an electric energy transmission pathway. The pressed material regions within the base unit fulfill both mechanical connection and electrical conduction roles, eliminating the need for separate specialized components and thereby reducing overall device complexity.

Implementation Method 1
an electrically conductive adhesive being additionally configured in the material thereof. By means of such an embodiment, specific zones of this base unit are improved, namely specifically those regions to which the electric energy unit is physically attached. On the one hand, these regions are designed to be more mechanically stable and, on the other hand, the general connectivity is improved thereby. In particular, by means of these embodiments with a pressed material region and/or a region which is impregnated with electrically conductive adhesive, in addition to the material region of the base unit, it is possible to transmit the electric energy from the electric energy unit to the base unit in an improved manner.
Implementation Method 2
The base unit is made of a porous foam body. The foam body is pressed in the electric connection regions and has a greater density than in the remaining region of the base unit.
