Integrated Rivet Component for Tool Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for creating a positive riveted connection between tools and tool receiving parts are complex and labor-intensive, especially when a large number of rivets are required, often leading to the substitution with welded connections in technical applications where materials cannot be welded.
Innovation Solution
A tool device with a component featuring a base body that integrates multiple solid rivets as a common setting head, allowing for simplified handling and assembly, where the rivets protrude through aligned openings in the tool and tool receiving part, and are deformed under pressure to form a non-detachable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual rivets are used to create a positive-locking connection, then the connection strength and reliability are improved, but the complexity of the assembly process and labor requirements increase significantly
Solution Approach 1:
The patent combines multiple individual rivets into a single integrated component with a common base body and multiple rivet shanks. This merging approach maintains the connection strength of multiple rivets while simplifying the assembly process to a single operation, directly resolving the contradiction between reliability and assembly complexity.
Solution Approach 2:
The integrated component serves multiple functions simultaneously: it provides multiple riveting points for strong connection while acting as a single assembly unit for simplified installation. The base body with multiple protruding rivet shanks enables one component to perform what previously required multiple separate rivets.
2Reliability
If multiple individual rivets are inserted and assembled separately, then the connection reliability is improved, but the labor time and manufacturing costs increase
Solution Approach 1:
By merging multiple rivets into one integrated component, the patent reduces the number of assembly operations from multiple separate insertions to a single installation action. This maintains connection reliability while significantly reducing assembly time and labor costs.
Solution Approach 2:
The multiple rivets are pre-assembled into a single integrated component before installation. This preliminary assembly of rivets into the base body structure eliminates the need for multiple separate insertion operations during final assembly, reducing time and labor requirements.
3Ease of manufacture
If a common base body with integrated rivets is used, then the assembly simplicity and cost-effectiveness are improved, but the manufacturing complexity of the integrated component increases
Solution Approach 1:
The patent merges multiple rivets with a base body into a single integrated component that can be manufactured as one piece using extrusion or similar processes. While the internal structure is complex, the manufacturing process consolidates multiple components into one, simplifying inventory management and assembly while the extrusion process handles the structural complexity efficiently.

AI summary
The invention relates to a component (30) for establishing a form-locking riveted connection between a tool (20) and a tool holding part (10), comprising a main member (31) and a plurality of rivets (32) which are integrated into the main member (30). The form-locking connection between the tool (20) and the tool holding part (10) is established by applying pressure to the rivets (32). The tool holding part (10) can be designed to cooperate with a tool holder of an oscillatingly driven power tool.
