Auxiliary Joining Part for Fiber-Reinforced Sheet Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for joining organic sheet parts or organic sheet parts with sheet metal parts, such as punch riveting, are not suitable for fiber or fabric reinforced plastics due to handling difficulties and inefficiencies.
Innovation Solution
A method using an auxiliary joining part consisting of a pin and a plate with a position of intended fracture, where the pin is used to pierce through the components, creating a form-fitted connection, and the plate is deformed to provide additional stability, allowing for efficient joining of sheet parts without the need for multiple loose components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional punch riveting is used to join organic sheet parts, then the joining process can be performed, but handling difficulties and inefficiencies occur due to the nature of fiber or fabric reinforced plastics
Solution Approach 1:
The auxiliary joining part is divided into two functional segments: a plate for distributing load and preventing positioning errors, and a pin for creating the form-fitted connection. This segmentation allows each component to be optimized for its specific function while working together as an integrated joining system suitable for organic sheet parts.
Solution Approach 2:
The auxiliary joining part serves as an intermediary element between the two organic sheet parts to be joined. Instead of directly joining the fragile fiber-reinforced plastics, the auxiliary part mediates the connection process, distributing forces and providing a reliable joining mechanism that accommodates the material characteristics of organic sheet parts.
2Reliability
If multiple loose individual components are used for joining, then the joining function can be achieved, but handling becomes difficult and inefficient
Solution Approach 1:
The plate and pin are merged into a single auxiliary joining part that functions as an integrated unit. This combination eliminates the need to handle multiple loose components separately, while still providing the complete joining function through the coordinated action of the plate (for load distribution and positioning) and the pin (for form-fitted connection).
3Device complexity
If components are joined without proper alignment features, then the joining process is simpler, but faulty positioning or slippage occurs during the joining process
Solution Approach 1:
The plate is designed with features that establish proper alignment and positioning of the auxiliary joining part relative to the organic sheet parts before the pin creates the form-fitted connection. This preliminary positioning action prevents faulty positioning or slippage during the joining process, ensuring manufacturing precision without significantly increasing process complexity.
4Productivity
If a simple connection method is used, then the joining process is faster, but the connection lacks rotational security
Solution Approach 1:
The auxiliary joining part combines two different functional elements (plate and pin) made of appropriate materials to achieve both simplicity and rotational security. The plate provides a stable base for positioning, while the pin creates a form-fitted connection that prevents rotation, together delivering a secure joint without compromising joining speed.

Implementation Method 1
the end of the pin which is pressed through the second component, and/or a washer which is optionally provided there is deformed in order to provide a form-locked connection to the second component
Implementation Method 2
the plate and/or the end of the pin which was originally remote from the plate, but is now adjacent to it, is deformed in order to also produce a form-fitted connection there

AI summary
A method of connecting a first component and a second component with the aid of an auxiliary joining part, wherein the auxiliary joining part is formed from a pin and a plate. A position of intended fracture is present between the plate and the pin. The first component, the second component and the auxiliary joining part are brought into a stacked arrangement such that the plate contacts the first component and the pin projects away from the side of the plate remote from the first component. A force is exerted on the pin of the auxiliary joining part in the direction towards the stacked components which leads to a fracture at a position of intended fracture and the pin is used in order to pierce slugs from the stacked components. The end of the pin which is pressed through the second component, and/or a washer which is optionally provided there, is deformed in order to provide a form-locked connection to the second component or to a washer which is provided there. Furthermore, an auxiliary joining part is claimed.
