Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional multi-component methods are used for producing elastic joint disks, then the production process is complex and costly with significant elastomer usage, but the structural stability and functionality are maintained
Solution Approach 1:
The patent merges the cord package supporting device with the elastomer body into a single integrated component. The elastomer body is directly molded onto the cord package supporting device, eliminating the need for separate components and assembly steps. This integration simplifies the production process, reduces the number of parts, and lowers manufacturing costs while maintaining the structural stability and functionality of the elastic joint disk.
Solution Approach 2:
The elastomer body serves multiple functions simultaneously: it provides structural support, acts as the elastic element for torque transmission, and integrates with the cord package supporting device as a unified component. This multi-functionality reduces the need for separate components and simplifies the overall construction of the elastic joint disk.
2Loss of substance
If conventional production methods with multiple components are used, then component stability is maintained, but elastomer usage and production costs increase
Solution Approach 1:
By integrating the cord package supporting device with the elastomer body into a single molded component, the patent eliminates the need for separate elastomer components that would otherwise be required to support the cord package. This integration reduces elastomer usage while simplifying production and lowering costs.
3Device complexity
If integral design of cord package supporting device is used, then production is simplified and costs reduced, but dimensional stability during cord winding must be maintained
Solution Approach 1:
The integral design merges the cord package supporting device with the elastomer body into a single component. This unified structure inherently provides dimensional stability during cord winding because the elastomer body and supporting device move as one piece, eliminating relative movement or deformation between separate components.
4Ease of manufacture
If fewer components and less elastomer are used, then production becomes more economical, but the structural integrity and functionality must be maintained
Solution Approach 1:
The patent achieves production economy by merging the cord package supporting device with the elastomer body into a single integrated component. This integration reduces the number of parts and elastomer usage while maintaining structural integrity because the unified design eliminates weak points at component interfaces and ensures continuous load paths throughout the structure.

AI summary
A cord package supporting device for supporting a cord package wound with a cord, such as for an elastic joint disk for connecting two shaft portions, is disclosed. The cord package includes two opposite arcuate cord regions and two tangential cord regions that connect the arcuate cord regions to each other and extend parallel to each other. In embodiments, the cord package supporting device includes a first redirecting portion and a second redirecting portion, about which in each case one arcuate cord region of the cord package is guided. In embodiments, the two redirecting portions are integrally connected to each other via a web. An elastic joint disk and a method for producing an elastic joint disk are also disclosed.
