Modular Manufacturing Cell Layout for High-Force Press Changeover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible manufacturing systems face limitations in incorporating a press due to restricted press force by overhead beams and table positioning, which hinders changeover of tooling and performs other operations like diagnostic testing and manual assembly effectively.
Innovation Solution
A modular manufacturing system with a cell framework, multiple-axis movable manufacturing components, and a tool exchanger that allows for enhanced press force and tool exchange, enabling precise positioning and simultaneous automated and manual operations within a manufacturing area.

Engineering Contradiction Analysis
1Force
If a press is incorporated into conventional flexible manufacturing systems with overhead beams, then press force is limited by the maximum loading on the overhead beams
Solution Approach 1:
The system divides the manufacturing functions into separate modules: a press module that can be detached and repositioned. This allows the press to be removed from the overhead beam structure, eliminating the load limitation while maintaining system flexibility through modular reconfiguration.
Solution Approach 2:
The press is designed with dynamic positioning capability, allowing it to move between different workstations along the manufacturing line. This dynamic repositioning enables the press to serve multiple stations, increasing adaptability while the press force is no longer constrained by overhead beam loading limits.
2Ease of operation
If a table is positioned between the press plates to move parts, then the table prevents changeover of tooling on the press plates
Solution Approach 1:
The part movement function is extracted from the press assembly and assigned to a separate conveyor system. This removes the table that was positioned between the press plates, allowing unobstructed access to the press plates for rapid tooling changeover while parts continue to be moved by the independent conveyor.
Solution Approach 2:
A conveyor system acts as an intermediary between workstations, handling part movement independently of the press. This mediator enables the press to focus solely on pressing operations with quick tooling changes, while the conveyor manages part transportation without interfering with press plate access.
3Ease of operation
If parts are moved to another station for diagnostic testing and manual assembly, then manufacturing efficiency is reduced due to part movement
Solution Approach 1:
The press station is designed as a universal workstation that can perform multiple functions: pressing operations, diagnostic testing, and manual assembly. By integrating these functions at a single location, parts remain stationary while the press and associated equipment provide diverse capabilities, eliminating the need for part movement and improving manufacturing efficiency.
Solution Approach 2:
Multiple manufacturing functions are merged into a single integrated press station. The press, diagnostic testing equipment, and manual assembly areas are combined at one workstation, allowing all operations to be performed on parts without moving them to separate stations, thereby enhancing productivity.
