Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current can seaming equipment is either too large and costly for small batch production or requires extensive training and is expensive to operate, lacking a cost-effective and efficient solution for smaller production needs.
Innovation Solution
A can seaming apparatus comprising a frame, can handling assembly, can driving assembly, and seam forming assembly, which includes a lower and upper chuck for can positioning, a motor-driven can driving assembly for rotation, and a seam forming assembly with rollers for forming the double seam can seal, designed for manual operation and adaptable for small batch production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large automated can seaming equipment is used, then productivity and sealing quality are improved, but device size and cost increase
Solution Approach 1:
The can seaming apparatus is divided into separate functional modules: a can holding assembly with upper and lower chucks, a seam forming assembly with rollers, and a driving mechanism. This segmentation allows each component to be optimized independently while maintaining overall functionality, reducing the total device size compared to integrated automated systems.
Solution Approach 2:
Instead of using a conventional automated system where the can moves through a fixed seaming station, this invention inverts the approach by holding the can stationary in chucks and bringing the seam forming rollers to the can. This inversion simplifies the mechanical structure and reduces equipment footprint while maintaining sealing effectiveness.
2Productivity
If automated can seaming equipment is used, then productivity is improved, but operational cost and training requirements increase
Solution Approach 1:
The apparatus incorporates self-aligning features where the upper and lower chucks automatically position the can centrally, and the seam forming rollers automatically engage the can flange and cover. These self-adjusting mechanisms eliminate the need for complex control systems and trained operators, allowing unskilled workers to operate the device effectively.
Solution Approach 2:
The device allows easy adjustment of sealing parameters such as roller pressure and position through simple mechanical adjustments rather than complex electronic controls. This enables operators to adapt to different can sizes and sealing requirements without extensive training, maintaining productivity while simplifying operation.
3Device complexity
If manual can seaming equipment is used, then cost is reduced, but manufacturing precision may deteriorate
Solution Approach 1:
The invention replaces complex automated mechanical systems with a simplified manual operating mechanism that uses precision mechanical components such as tapered chucks for can holding, roller frames with adjustable pressure, and overcenter locking mechanisms. These mechanical elements provide consistent, repeatable sealing quality without requiring expensive automated control systems.
Solution Approach 2:
The seam forming assembly with its rollers and roller frame is designed to accommodate different can sizes and types through adjustable positioning and pressure mechanisms. This universal design maintains high sealing quality across various applications while keeping the device structure simple and cost-effective.

AI summary
A can seaming apparatus including a frame, a can handling assembly, a can driving assembly and a seaming assembly. The can seaming apparatus is configured to seal a lid to a can through a double seam can seal. The can is positioned and clamped between an upper and a lower chuck. The can driving assembly spins the can and the upper and lower chucks about an axis. The seaming assembly includes two rollers mounted to a roller frame which pivots about an axis relative to the frame. The roller frame can be pivoted so as to selectively have the two rollers sequentially engage the can to form the necessary crimping operations.
