Cell-Based Mobility Production Flow for Mixed-Model Work Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle production methods face inefficiencies and work delays due to differences in working times between vehicle models in mixed production environments, particularly in cell-based smart factories, where a single work assignment optimized for one model does not account for varying times required for different models, leading to idle time and reduced productivity.
Innovation Solution
A method for operating a cell-based mobility production system that reassigned works required in each cell based on a determined feeding order, optimizing the total production time and minimizing work delays by adjusting working times across cells, and planning logistics flows to prevent bottlenecks and ensure the shortest production time and standby times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single work assignment is designated to respective vehicle models by a conveyor-based system, then production can be carried out with repetitive operations, but work delays occur due to differences in working times between vehicle models in mixed production
Solution Approach 1:
The patent implements dynamic work assignment that adapts to different vehicle models and their specific working time requirements. Instead of fixed repetitive operations, the system dynamically adjusts which works are assigned to which cells based on the feeding order and model-specific time requirements, preventing work delays in mixed production environments
Solution Approach 2:
The system changes the parameters of work assignment based on vehicle model characteristics. By analyzing the working times required for different vehicle models and adjusting the work distribution parameters accordingly, the system optimizes production flow and eliminates delays caused by time differences between models
2Device complexity
If vehicle bodies are fed in a predetermined sequence with single work assignment, then production flow is simplified, but bottlenecks occur when vehicle models change due to different working times
Solution Approach 1:
The system performs preliminary analysis of working times for different vehicle models before production begins. By pre-determining the feeding order and pre-assigning works to cells based on this analysis, the system prevents bottlenecks before they occur, maintaining smooth production flow without excessive complexity
Solution Approach 2:
The production system is segmented into multiple independent cells, each capable of performing specific works. This segmentation allows different vehicle models to be processed simultaneously in different cells with model-appropriate work assignments, preventing bottlenecks while maintaining manageable system complexity
3Adaptability or versatility
If cell-based smart factory is implemented with flexible cell arrangement, then production can adapt to different vehicle models, but well-prepared overall production plan is needed to minimize bottlenecks
Solution Approach 1:
The system incorporates feedback mechanisms that monitor the production process in real-time and provide information about work progress and bottlenecks. This feedback enables dynamic adjustment of work assignments and feeding orders, allowing the flexible cell-based system to self-optimize without requiring overly complex external planning
Solution Approach 2:
The system performs preliminary determination of feeding orders and work assignments based on vehicle model characteristics and cell capabilities. This advance planning, combined with the flexible cell arrangement, enables the system to adapt to different models while minimizing bottlenecks through pre-optimized configurations
