Solution Overview

Problem

Existing can seamers require expensive and time-consuming replacement of seaming rollers due to their high-performance materials, necessitating laborious adjustments and downtime.

Innovation Solution

A seaming roller design with a detachable seaming profile that is connected to a rotating body via a fastening mechanism, allowing quick and easy replacement without adjusting the entire seaming roller or bolt.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the seaming roller is made from high-performance materials to ensure durability and reliability, then the reliability is improved, but the cost increases and replacement becomes time-consuming

Engineering Contradiction:
ImprovereliabilityVSAvoidreplacement time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The seaming roller is divided into two separate components: a durable rotating body made from high-performance materials and a replaceable seaming profile. The rotating body maintains reliability and durability, while the profile can be quickly changed without replacing the entire roller, thus reducing replacement time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The seaming profile is extracted as a separate detachable component from the rotating body. This allows the profile to be independently replaced without affecting the durable rotating body, enabling quick changes while maintaining the reliability of the core structure.

Inventive Principle:
Principle #2Taking out (Extraction)

2Manufacturing precision

If the entire seaming roller is replaced when the profile is worn or for different can combinations, then the sealing quality is maintained, but the downtime and labor costs increase

Engineering Contradiction:
Improvesealing qualityVSAvoiddowntime
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

By segmenting the seaming roller into a permanent rotating body and a replaceable profile, the system allows selective replacement of only the worn profile component. This maintains sealing quality through precise profile replacement while minimizing downtime since only the profile needs to be changed, not the entire roller assembly.

Inventive Principle:
Principle #1Segmentation

3Device complexity

If the seaming roller is designed as a single integrated component, then the structure is simple, but replacement and adjustment become laborious and time-consuming

Engineering Contradiction:
Improvestructural simplicityVSAvoidreplacement ease
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The seaming roller is segmented into a rotating body and a detachable profile connected via a fastening mechanism. This segmentation enables easy replacement of the profile without complex adjustments, while the overall structure remains relatively simple through the use of a straightforward fastening and release mechanism.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a seaming roller for closing a container (200), comprising a rotating body (10) which can rotate on a bolt (11) for closing the container (200). The rotating body (10) comprises a first main side (111) and a second main side (101) which is different from the first main side (111), and a bearing (14). The bolt (11) is arranged on the bearing (14) above the first main side (111) such that the rotating body (10) can be rotated about the bolt (11) in the circumferential direction of the second main side (101) when closing the container. According to the invention, the seaming roller (1) also comprises an exchangeable seaming profile (12) for creating a seam between a container lid (202) and a body (201) of the container (200), and a fastening mechanism (15, 16). The exchangeable seaming profile (12) is detachably connected to the rotating body (10) via the fastening mechanism (15, 16).
