Clock-Face Aircraft Assembly Layout for Continuous Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linear assembly lines for manufacturing large complex systems like aircraft require substantial floor space and are prone to production delays, which can cause ripple effects throughout the assembly process.
Innovation Solution
A clock face factory layout with stationary build stations and a hub-and-spoke tool track system, where each aircraft remains stationary and components are conveyed to it, allowing for continuous-flow production and reducing floor space requirements, with mobile transport transforming into task-specific tools and an overhead crane for efficient assembly.

Engineering Contradiction Analysis
1Productivity
If a linear assembly line is used to assemble aircraft, then assembly tasks can be performed at multiple build stations, but the factory requires substantial floor space
Solution Approach 1:
The patent transitions from a linear one-dimensional assembly line to a radial two-dimensional clock-face layout with build stations arranged around a central hub. This dimensional change allows multiple aircraft to be assembled simultaneously in different radial positions, increasing productivity while optimizing floor space utilization through circular geometry rather than linear extension.
Solution Approach 2:
The factory is segmented into multiple independent build stations positioned at different clock positions (e.g., 12:00, 3:00, 6:00, 9:00), each capable of assembling aircraft independently. This segmentation allows parallel production at multiple stations simultaneously, improving overall productivity while the radial arrangement minimizes the total floor space required compared to a linear configuration.
2Ease of operation
If a moving assembly line is used to assemble aircraft, then work crews can move with the aircraft, but production delays at one station cause ripple effects throughout the line
Solution Approach 1:
Instead of moving the aircraft through a linear sequence of build stations, the patent inverts the approach by bringing all build stations to the stationary aircraft arranged in a radial pattern. Each aircraft remains at its assigned clock position while work crews and equipment move to the aircraft, eliminating the ripple effect of production delays that plagues linear moving assembly lines.
Solution Approach 2:
The production system is segmented into independent build stations at different clock positions, each capable of operating autonomously. This segmentation isolates production delays to individual stations rather than propagating them throughout the entire line, maintaining production continuity and reliability across the factory.
3Productivity
If a linear assembly line is used, then aircraft can be assembled sequentially, but the layout creates complex logistical flows and infrastructure requirements
Solution Approach 1:
The patent replaces the linear one-dimensional layout with a radial two-dimensional clock-face configuration. This dimensional change simplifies logistical flows by providing direct radial access from a central hub to each build station, eliminating the complex sequential infrastructure required for linear assembly lines while maintaining sequential assembly capability through coordinated production at multiple radial positions.

AI summary
A factory for assembling aircraft or other systems includes a factory floor with multiple build stations. The factory floor includes a hub-and-spoke tool track having radial track sections connected to and extending radially from a circular center hub section. Each track section terminates at a respective build station. A mobile transport travels along the track to the build stations, transforms into different join tools at a predetermined build station, and thereafter engages and supports the components. An overhead crane may perform another task at each build station. The factory floor may include a first floor positioned below a smaller diameter second floor with ramps interconnecting the floors. A center tower is surrounded by the floor(s), with the center tower defining rooms. An aircraft may be assembled via a method using the above-noted factory.
