Additive Assembly Guides for Tubular Member Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional manufacturing aides require secondary processing steps that increase time, effort, and introduce errors, necessitating improved adaptability and economic viability in assembly methods.
Innovation Solution
The method involves using additive manufacturing to deposit a guide material on a tubular member, allowing for precise insertion and braze material application without melting the surface, utilizing capillary action and microstructural deformation for interference fits and assembly aids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional secondary processing methods are used for assembly assistance, then assembly guidance can be provided, but assembly time increases and errors are introduced
Solution Approach 1:
The patent combines the assembly guidance function directly into the tubular member by additively manufacturing raised features as integral parts of the component itself, eliminating the need for separate secondary processing fixtures or guides. This merging of functions reduces assembly time while maintaining reliability.
Solution Approach 2:
The raised assembly guidance features are manufactured as integral parts of the tubular member during the primary manufacturing process, rather than being added as separate secondary operations. This preliminary incorporation of assembly aids eliminates additional processing steps and reduces overall assembly time.
2Productivity
If additive manufacturing is used to deposit assembly aids, then assembly process is simplified and time is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies additive manufacturing selectively to deposit raised features only in specific locations on the tubular member where assembly guidance is needed. This localized application allows for simplified manufacturing in non-critical areas while maintaining precision only where required for assembly guidance, balancing productivity and precision requirements.
