Closure Cap Assembly and Slotting Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing locking caps with a retainer ring and lid on a connecting flange are inefficient, requiring separate devices for assembly and slot insertion, which can lead to instability and increased risk of damage during the process.
Innovation Solution
A device that integrates both assembly and slot insertion in a single process, using a carousel with carrier stamps and a slot knife to create slots between the retainer ring and lid, ensuring a secure connection while maintaining stability and preventing accidental disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate devices are used for assembly and slot insertion, then device specialization is improved, but device complexity and production time increase
Solution Approach 1:
The patent combines the assembly device and slot insertion device into a single integrated device. The assembly section assembles the closure cap with the connecting flange, and the slot section subsequently inserts slots between the retainer ring and lid, all within one device structure. This eliminates the need for separate devices while maintaining functional specialization through distinct sections.
Solution Approach 2:
The integrated device performs multiple functions: it assembles the closure cap components, positions them on the connecting flange, and inserts slots between the retainer ring and lid. The single device structure incorporates both assembly and slotting capabilities, making it a multi-functional unit that replaces multiple specialized devices.
2Ease of manufacture
If separate devices are used for assembly and slot insertion, then functional specialization is improved, but manufacturing time and productivity decrease
Solution Approach 1:
The integrated device enables continuous production by eliminating the need to transfer workpieces between separate assembly and slotting devices. The closure cap is assembled in the assembly section and immediately processed in the slot section without interruption, maintaining continuous useful action and improving manufacturing efficiency.
Solution Approach 2:
By merging the assembly and slot insertion operations into a single device, the patent eliminates idle transfer time between devices. The sequential arrangement of assembly and slot sections allows uninterrupted processing, directly improving productivity while maintaining functional differentiation.
3Ease of operation
If slots are inserted before assembly, then slot insertion ease is improved, but stability and damage risk increase
Solution Approach 1:
The device performs assembly as a preliminary action before slot insertion. The closure cap is first assembled with the connecting flange to establish a stable structure, and only then are slots inserted between the retainer ring and lid. This sequencing prevents damage by ensuring structural stability before the slotting operation.
4Ease of operation
If the lid is disconnected from the retainer ring, then ease of opening is improved, but environmental disposal risk increases
Solution Approach 1:
The closure cap is segmented into a lid and retainer ring connected by slots, allowing relative movement for opening. However, the slots are designed to maintain a permanent connection rather than complete separation, enabling the lid to open for access while remaining attached to the retainer ring to prevent environmental disposal.

AI summary
A device for manufacturing a closure cap on a connecting flange has an assembly section for placing the closure cap on the connecting flange and a cutting section for creating the slot between a retaining ring and a cover of the closure cap, wherein the cutting section is located downstream of the assembly section.
