Innovation Solution
A riveting apparatus with integrated rivet insertion and riveting devices, utilizing electric motors for precise and fast operations, and a cam mechanism for adaptable rivet handling, supported by a closed-loop frame structure for high accuracy and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If production speed is increased to achieve high-volume output, then productivity improves, but manufacturing precision and functionality quality deteriorate
Solution Approach 1:
The riveting apparatus is divided into separate functional modules: a rivet insertion device that places rivets and a riveting device that performs the riveting operation. This segmentation allows each module to be optimized independently - the insertion device for speed and the riveting device for precision, thereby resolving the contradiction between high productivity and manufacturing precision.
2Productivity
If production speed is increased, then productivity improves, but material waste increases
Solution Approach 1:
The rivet insertion device performs preliminary positioning of rivets before the riveting operation. This preliminary action ensures that rivets are correctly placed and oriented, preventing misfires and material waste while maintaining high production speed through automated, rapid insertion.
3Productivity
If production speed is increased, then productivity improves, but system reliability deteriorates
Solution Approach 1:
A transport system acts as an intermediary between the rivet insertion device and the riveting device, conveying articles through defined positions. This intermediary mechanism coordinates the high-speed insertion operations with the precision riveting operations, ensuring smooth workflow and preventing operational jams that would compromise reliability.
