Solution Overview

Problem

Reconfiguring existing can bodymakers to produce cans of different diameters is a time-consuming process, requiring significant downtime and reducing manufacturing flexibility, as existing systems require extensive tooling changes and realignment, which is costly and inefficient for high-volume can production.

Innovation Solution

A modular can bodymaker design with precision mounts and adjustable toolpack modules that allow for quick and accurate alignment and replacement of components, enabling rapid changeovers between different can diameters without disturbing the radial alignment of other dies, using wear bars and bearing adjustment mechanisms for precise alignment and quick-release fixings for module attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional bodymaker tooling is reconfigured to produce cans of different diameters, then product versatility is improved, but changeover time increases significantly

Engineering Contradiction:
Improveability to produce different can diametersVSAvoidchangeover time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The bodymaker is divided into modular components, with the toolpack framed as a separable module that can be quickly exchanged. This segmentation allows the toolpack to be pre-configured for different can diameters and swapped without reconfiguring the entire machine, thereby reducing changeover time while maintaining versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple toolpacks are pre-configured for different can diameters and specifications before production runs. This preliminary preparation eliminates the need for time-consuming on-site reconfiguration, as operators can simply swap between pre-ready toolpacks when changing production requirements.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If traditional bodymaker tooling is reconfigured for different can diameters, then manufacturing flexibility is improved, but production downtime increases

Engineering Contradiction:
Improvemanufacturing flexibilityVSAvoidproduction continuity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

By segmenting the toolpack as a独立 module, the system enables quick exchange between different toolpack configurations without halting the entire production line for extended periods, thus maintaining productivity while improving flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized toolpack interface and precision mounting system allow a single bodymaker platform to universally accommodate multiple toolpacks designed for different can specifications, enabling one machine to perform multiple functions across various product lines.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If traditional bodymaker tooling is realigned for new can diameters, then adaptability is improved, but alignment complexity increases

Engineering Contradiction:
Improveability to produce different can diametersVSAvoidalignment process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

All alignment adjustments are performed in advance during toolpack manufacturing. The toolpacks arrive pre-aligned with precision mounting features, eliminating complex on-site alignment procedures and reducing the skill level required for changeovers.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Traditional mechanical alignment procedures are replaced with precision-engineered mounting features and datum references built into the toolpack structure. This substitution of alignment methodology with precision manufacturing reduces complexity and improves repeatability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
