Solution Overview

Problem

Traditional manufacturing methods require expensive tooling and equipment for welding and subsequent machining of components, which becomes impractical for larger components due to the difficulty in handling and positioning them accurately during welding operations.

Innovation Solution

The use of alignment spacer assemblies comprising spacer segments with angled inner and outer faces and alignment bores, secured by a securement pin or clamp, to position components at a fixed distance for welding, allowing for precise alignment and coupling without the need for extensive machinery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional welding and machining methods are used for larger components, then manufacturing precision can be achieved through downstream machining, but device complexity and equipment costs increase significantly

Engineering Contradiction:
Improvealignment precisionVSAvoidequipment complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The alignment spacer assembly performs preliminary positioning and alignment of components before welding. The spacers are pre-positioned between components to establish precise spacing and alignment, allowing welding to proceed without requiring complex positioning equipment. This preliminary action eliminates the need for expensive downstream machining operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The alignment spacer assembly acts as an intermediary device between components during welding. The spacers serve as mediators that maintain fixed distances and alignment between components, enabling precise positioning without requiring complex external positioning equipment or machinery.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If traditional welding methods are used for larger components, then components can be welded together, but handling and positioning difficulty increases

Engineering Contradiction:

AI summary

A spacer assembly and method for using same to fix a first component to a second component are provided. The method includes positioning the first and second spacer segments between the first and second components, the first and second spacer segments each including an inner face, an opposite outer face, and an exterior surface extending along a longitudinal axis between the inner face and the outer face. The exterior surfaces of the first and second spacer segments are coaxially aligned and secured by a securing device such that the inner faces of the first and second spacer segments define supplementary non-perpendicular angles relative to the longitudinal axis and the outer faces of the first and second spacer segments are parallel to one another. The securing device and the first and second spacer segments are removed after the first component is mechanically coupled to the second component.
