Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common closure system is used for multiple reaction cells, then device complexity is reduced, but individual pressure control and element replacement capability are lost
Solution Approach 1:
The closure system is segmented into individual closure elements, each associated with a specific reaction cell. Each closure element can be independently opened and closed, allowing individual cells to be accessed, replaced, or pressurized without affecting other cells. This segmentation resolves the contradiction by maintaining low overall device complexity while enabling full adaptability for individual cell operations.
Solution Approach 2:
The closure elements are designed to be dynamically adjustable, allowing the system to transition between a unified closed state (for simultaneous operation) and an individually open state (for replacement or maintenance). This dynamic capability enables the system to adapt to different operational requirements without increasing permanent device complexity.
2Productivity
If multiple reaction cells are tested in parallel, then productivity increases, but device complexity and control difficulty increase
Solution Approach 1:
The apparatus is divided into modular reaction cell units, each with its own closure element and pressure control capability. This segmentation allows multiple cells to operate in parallel (increasing productivity) while each module remains relatively simple in structure. The modular design prevents the overall device complexity from scaling linearly with the number of cells.
Solution Approach 2:
The reaction cells and closure elements are designed as universal, interchangeable components that can be used in any position within the apparatus. This universality allows the system to handle multiple cells with a standardized set of components, avoiding the need for custom-designed complex systems for each additional cell.
3Ease of manufacture
If conventional closure systems are used, then manufacturing is simpler, but sealing reliability under pressure is insufficient
Solution Approach 1:
The sealing function is extracted as a separate, dedicated component within the closure element, distinct from the structural housing. This allows the sealing mechanism to be optimized independently for reliability while the overall closure structure remains simple to manufacture. The separated sealing component can be replaced or upgraded without redesigning the entire closure system.
Solution Approach 2:
The closure elements incorporate pre-designed sealing features and pressure distribution mechanisms that are built in during manufacturing. These features provide built-in protection against sealing failures before they occur, ensuring reliable fluid-tight connections under pressure without requiring complex post-manufacturing adjustments or assemblies.

AI summary
The invention relates to an apparatus and a method for investigating chemical processes in plate-like reaction cells which can be fixed flexibly and independently in the apparatus, an investigation of stacks of plate-like reaction cells also being possible. The plate-like reaction cells are positioned with an outer plate surface in a receiving unit and are then pressed against one another by one or more piston tensioners, the pistons of the piston tensioners acting on the outer plate surface of the plate-like reaction cells, more specifically in each case on the plate surface that is opposite the receiving unit, and sealing the reaction cells tightly and detachably by the action of the pressing force. The plate-like reaction cells or stacked plate-like reaction cells each comprise a plurality of plate-like function elements, with each plate-like reaction cell having at least one feed line for a reactant and at least one discharge line for a product, or with each stacked plate-like reaction cell having at least one feed line for a reactant and at least one discharge line for a product.
