Solution Overview
Problem
Conventional vehicle manufacturing methods are inflexible and unable to efficiently produce various vehicle types, leading to limitations in responding to diverse customer needs and accommodating rapid changes in product cycles, especially in abnormal situations or when operating within urban environments.
Innovation Solution
A parallel cell-based mobility production system comprising a front serial production line, a parallel production line with matrix-arranged cells, and a rear serial production line, allowing for flexible operation and rapid changes in production facilities, enabling the production of multiple vehicle types without shutdowns or separate constructions, even in abnormal situations, and allowing for urban factory installations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional mass production method with conveyors is used, then production efficiency for single vehicle type is improved, but flexibility to produce various vehicle types deteriorates
Solution Approach 1:
The production system is divided into multiple independent cells (first cell, second cell, third cell, fourth cell) that can operate autonomously. Each cell is equipped with its own conveyor and can process vehicles independently, allowing simultaneous production of different vehicle types without interfering with other cells. This segmentation enables both high productivity within each cell and flexibility across the entire system.
Solution Approach 2:
The system dynamically assigns vehicles to different cells based on vehicle type and production requirements. The control unit can redirect vehicles between cells and adjust production sequences in real-time, enabling the system to adapt to changing customer demands and produce various vehicle types efficiently without reconfiguring the entire production line.
2Device complexity
If a consistent sequence production line is used, then manufacturing process simplicity is improved, but response to diverse customer needs deteriorates
Solution Approach 1:
The production line is segmented into multiple independent cells, each capable of performing complete or partial manufacturing processes. This allows the system to maintain simple, standardized processes within each cell while combining them in various sequences to meet diverse customer requirements for different vehicle types.
Solution Approach 2:
Each cell is designed with universal capabilities to handle multiple vehicle types and manufacturing tasks. The cells can be configured to perform different operations based on the vehicle type being produced, enabling a single cell to serve multiple functions and the entire system to respond flexibly to diverse customer needs.
3Stability of the object's composition
If all processes have the same working hours, then production line synchronization is improved, but production continuity in abnormal situations deteriorates
Solution Approach 1:
By dividing the production line into independent cells with separate conveyors and control systems, each cell can operate autonomously during abnormal situations. If one cell experiences issues, others can continue production, maintaining overall production continuity while allowing individual cells to be maintained or adjusted independently.
Solution Approach 2:
The system allows different working hours and operational parameters for each cell based on actual production needs and abnormal situations. The control unit can adjust the operation status, speed, and sequence of each cell independently, enabling flexible response to disruptions while maintaining synchronization when normal operations resume.
4Ease of manufacture
If traditional vehicle manufacturing method is used, then cost efficiency is improved, but ability to quickly produce various vehicles deteriorates
Solution Approach 1:
The segmented cell-based structure allows for modular expansion and efficient utilization of resources. Each cell can be optimized for specific tasks while sharing common infrastructure, reducing overall manufacturing costs. Simultaneously, the system can quickly reconfigure production across multiple cells to produce various vehicle types efficiently.
Solution Approach 2:
The dynamic vehicle assignment and cell configuration capabilities enable the system to optimize production sequences and resource allocation in real-time, reducing changeover times and setup costs when switching between different vehicle types. This dynamic flexibility allows quick production of various vehicles without sacrificing cost efficiency.
