Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a modular design with interchangeable sealing elements and shaping elements is implemented, then adaptability and flexibility are improved, but device complexity increases due to multiple components
Solution Approach 1:
The support element is designed as a universal carrier that can accommodate multiple different sealing elements and shaping elements through a standardized receiving section. This allows a single support element to serve multiple sealing applications by simply changing the sealing element, thereby improving adaptability while managing complexity through standardization.
Solution Approach 2:
The sealing arrangement is divided into separate, interchangeable components: support element, sealing element, and shaping element. Each component can be independently selected and replaced, allowing customization for different sealing requirements without redesigning the entire assembly, thus improving adaptability while keeping individual components relatively simple.
2Adaptability or versatility
If multiple sealing elements and shaping elements are provided for different applications, then versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The support element with its hollow cylindrical receiving section serves as a universal base for multiple sealing applications. By standardizing the support element design, manufacturing complexity is reduced as this core component can be produced in large quantities for different sealing element configurations.
Solution Approach 2:
The support element is pre-configured with a receiving section designed to accommodate various sealing elements and shaping elements. This preliminary preparation of the support structure simplifies subsequent assembly and manufacturing processes for different sealing configurations.
3Ease of manufacture
If a standardized kit of components is used, then ease of manufacture is improved, but device complexity increases due to assembly requirements
Solution Approach 1:
The sealing arrangement is segmented into distinct components (support element, sealing element, shaping element) that can be manufactured separately and then assembled. This segmentation enables each component to be optimized for its specific manufacturing process while simplifying assembly through clear functional boundaries.
Solution Approach 2:
The standardized support element with its receiving section provides a universal interface for assembling different sealing elements and shaping elements. This standardization simplifies the assembly process by providing consistent mounting requirements across different configurations.

AI summary
In order to provide a sealing arrangement (100) which has a modular design and is flexible in use, it is proposed that the sealing arrangement comprises the following: a ring-shaped sealing element (108) which in the assembled state bears against the shaft (104) for sealing; a ring-shaped carrier element (106) for receiving the sealing element; a shaping element (110), which is different from the carrier element, for shaping and/or supporting the sealing element.
