Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the granulating blade is clamped between the blade arm and adjusting element by means of screws, then the blade can be securely fastened, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The blade assembly is divided into separate functional components: a positioning component that provides rough positioning through bearing surfaces, and adjusting elements that provide fine positioning. This segmentation allows each component to perform its specific function independently, simplifying the overall assembly process while maintaining secure fastening.
Solution Approach 2:
The positioning component is pre-configured with bearing surfaces that provide rough positioning of the granulating blade before final adjustment. This preliminary positioning action eliminates the need for complex alignment procedures during assembly, reducing assembly complexity while ensuring reliable blade fastening.
2Manufacturing precision
If multiple adjusting elements and screws are used for blade positioning, then precise positioning can be achieved, but the assembly time increases and operator exposure to hazardous areas increases
Solution Approach 1:
Positioning functions are segmented into two distinct stages: rough positioning by the positioning component's bearing surfaces, and fine positioning by adjusting elements. This division allows operators to complete the time-consuming rough positioning quickly without exposure to hazardous areas, then perform precise adjustments from a safe position, reducing both assembly time and operator exposure.
Solution Approach 2:
The positioning component acts as an intermediary between the blade arm and the granulating blade, providing a stable reference framework through its bearing surfaces. This intermediary structure enables rough positioning to be established quickly and accurately, reducing the time operators must spend in hazardous areas while maintaining the precision needed for subsequent fine adjustments.
3Manufacturing precision
If the blade is positioned and adjusted in place on the heated perforated plate, then positioning can be performed, but operator safety is compromised due to exposure to heated components
Solution Approach 1:
The positioning component provides preliminary rough positioning of the granulating blade before the blade is fully installed in the hazardous heated area. This allows operators to establish the basic position from a safe location, then make minor fine adjustments if needed, minimizing exposure to heated components while maintaining positioning precision.
Solution Approach 2:
The positioning component serves as an intermediary structure that extends into the hazardous heated area, allowing operators to perform positioning operations from a safe position. The bearing surfaces of the positioning component provide stable reference points for blade positioning without requiring operator exposure to the heated perforated plate.
