Solution Overview

Problem

The existing forward mounting assembly for bodymakers is time-consuming to install, requires precise alignment, and can cause damage if misaligned, occupying valuable industrial space and interfering with other operations.

Innovation Solution

A unitary forward mounting assembly with a cradle portion and support arm portions integrated into a single body, allowing for alignment and assembly at a remote location before coupling to the bodymaker frame, eliminating the need for machined coupling surfaces and alignment processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If separate cradle and support arms are assembled on-site with machined coupling surfaces, then alignment precision can be achieved, but installation time increases and risk of damage occurs

Engineering Contradiction:
Improvealignment precisionVSAvoidinstallation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent combines the cradle and support arms into a single unitary forward mounting assembly that is pre-assembled and pre-aligned at the manufacturing location. This eliminates the need for on-site alignment of separate components with machined coupling surfaces, thereby reducing installation time while maintaining alignment precision through factory-controlled manufacturing.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If separate cradle and support arms are assembled on-site, then adaptability to different bodymakers is improved, but device complexity and alignment requirements increase

Engineering Contradiction:
Improveadaptability to bodymakersVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the forward mounting assembly into a unitary assembly that can be removed and installed as a single module on different bodymaker platforms. This modular approach maintains adaptability to various bodymakers while reducing assembly complexity by eliminating the need to align multiple separate components during installation.

Inventive Principle:
Principle #1Segmentation

3Strength

If machined coupling surfaces are used for cradle and support arms, then connection strength is improved, but installation difficulty and space requirements increase

Engineering Contradiction:
Improveconnection strengthVSAvoidinstallation ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The cradle and support arms are pre-assembled and pre-strengthened with appropriate connections at the manufacturing location before being installed as a unitary assembly. This preliminary action ensures connection strength is achieved during manufacturing under controlled conditions, while simplifying the installation process by eliminating the need for on-site machining and alignment operations.

Inventive Principle:
Principle #10Preliminary action
