Aircraft Machining Layout for Single-Platform Tool Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing processing systems for aircraft structural components require complex and time-consuming service work due to the inability of service personnel to access both the upper and lower tool units from a single service platform, leading to inefficiencies and risks of tool parts being left behind in the processing area.
Innovation Solution
The processing system allows the upper and lower tools to be moved and accessed from a common service platform, eliminating the need for additional service platforms and ensuring that both tools can be serviced from a single accessible location, thereby separating the processing and service areas and simplifying maintenance and tool changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate service platform is provided for the upper tool unit, then the upper tool unit becomes accessible, but the service work becomes more complex and time-consuming
Solution Approach 1:
The patent merges the service access for both upper and lower tool units to a single fixed service platform. The lower tool unit is positioned to be accessible from this platform, and the upper tool unit is made movable to also become accessible from the same platform during service. This consolidation eliminates the need for multiple service platforms or complex moving service platforms, reducing service complexity while maintaining accessibility to both tool units.
2Ease of operation
If the service platform extends into the machining area, then the upper tool unit becomes accessible, but the machining area is compromised and modifications are required
Solution Approach 1:
The upper tool unit is designed to be movable between machining and service positions. During machining operations, the upper tool unit occupies the machining area to perform operations. During service operations, the upper tool unit is moved to a service position that is accessible from the fixed service platform located in the service area. This dynamic positioning allows the machining area to remain fully available during machining operations while providing access to the upper tool unit during service without requiring the service platform to encroach on the machining area.
