Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components like snap nuts and press-in nuts are used for torque transmission, then reliable connection is achieved, but device complexity and number of components increases
Solution Approach 1:
The patent combines the driving element and the threaded element into a single integrated component. The driving element is injection-molded directly onto the lateral surface of the threaded element, eliminating the need for separate snap nuts or press-in nuts. This integration maintains reliable torque transmission while reducing the total number of components in the assembly.
2Reliability
If additional components like snap nuts and press-in nuts are used, then torque transmission is ensured, but installation space required increases
Solution Approach 1:
The driving element is merged with the threaded element through injection molding, creating a compact integrated component. This eliminates the need for additional space that would be required for separate snap nuts or press-in nuts, thereby reducing the overall installation space while maintaining effective torque transmission capabilities.
3Adaptability or versatility
If multiple separate components are used for tolerance compensation, then functionality is achieved, but manufacturing and assembly complexity increases
Solution Approach 1:
The driving element and threaded element are combined into a single injection-molded component, significantly simplifying the manufacturing process. Instead of requiring separate manufacturing and assembly steps for multiple components, the integration allows for one-step production, reducing both manufacturing complexity and assembly operations while preserving the full tolerance compensation functionality.

Function Achieved in This Case
The solution reduces the number of components needed, minimizes installation space, and ensures efficient torque transmission, allowing for compact and reliable compensation of tolerances between interconnected components.
Implementation Method 1
a driving element which is arranged in the inner cavity of the compensating element and is in frictional engagement with the screw element passing through the cavities, such that a torque exerted by the screw element can be transmitted to the compensating element
Implementation Method 2
a hollow-cylindrical compensating element which is in threaded engagement with the base element and can be moved from a starting position into a compensating position by means of rotation relative to the base element

AI summary
A device for compensating for tolerances between two components to be interconnected may have a hollow-cylindrical compensating element connected with a hollow-cylindrical base element. The device may also have a threaded element for screwing together with a screw element that extends through an inner cavity of the base element and an inner cavity of the compensating element. The device may also have a driving element which is arranged in the inner cavity of the compensating element and is in frictional engagement with the screw element passing through the cavities, such that a torque exerted by the screw element can be transmitted to the compensating element. The threaded element for screwing together with the screw element is formed in the inner cavity of the compensating element as an inner thread. An arrangement for compensating for tolerances between two components to be interconnected is also described.
