Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional skid or slat-chain conveying is employed for interior trim line and exterior assembly line, then the assembly line can operate, but the civil foundation requires special structure leading to high investment, inconvenience of reformation, and longer shutdown period
Solution Approach 1:
The patent replaces fixed mechanical conveying systems with mobile robots equipped with navigation devices. The robots dynamically move along predetermined paths to transport vehicles between assembly stations, enabling flexible reconfiguration of the assembly line without civil construction changes. This dynamic approach allows rapid adaptation to different vehicle models and production requirements.
Solution Approach 2:
The patent substitutes traditional mechanical conveying systems (skid chains, slat chains, fixture lines) with autonomous mobile robots. The robots use navigation devices and control systems instead of mechanical infrastructure, eliminating the need for special civil foundations and enabling easy reformation through software updates rather than physical reconstruction.
2Ease of manufacture
If fixture mechanical conveying line is used to create lower body operating platform, then the chassis line can function, but the fixed form and high initial investment increase difficulty of late reformation and maintenance
Solution Approach 1:
The patent replaces fixed mechanical conveying infrastructure with mobile robots that navigate autonomously. The lower body operating platform is no longer created by fixed fixtures but by mobile robots that can be easily repositioned and reconfigured. This substitution dramatically improves ease of reformation and maintenance.
Solution Approach 2:
The mobile robots serve multiple functions: they transport vehicles, position components, and can be reconfigured for different vehicle models. A single robot system can perform various assembly tasks across different production lines, eliminating the need for dedicated fixed infrastructure for each function.
3Reliability
If traditional final assembly line with fixed infrastructure is used, then assembly operations can be performed, but the high investment and difficulty in adaptation to rapid vehicle model updates create market response delays
Solution Approach 1:
The patent implements a dynamic assembly line where mobile robots can be easily added, removed, or repositioned based on production requirements. The navigation paths and assembly sequences can be modified through software updates, enabling rapid adaptation to new vehicle models while maintaining stable and reliable assembly operations through controlled robot coordination.
Solution Approach 2:
The patent enables rapid adaptation by changing operational parameters (navigation paths, assembly sequences, robot positions) rather than physical infrastructure. This allows the system to respond quickly to vehicle model updates by modifying control software and robot configurations without costly civil construction or mechanical reinstallation.
4Adaptability or versatility
If large plate line for interior trims and fixture line are omitted, then investment and shutdown period are reduced, but the mechanical conveying form must be simplified
Solution Approach 1:
The patent replaces complex mechanical conveying systems with autonomous mobile robots that use navigation and control systems. This substitution simplifies the mechanical infrastructure while maintaining or enhancing conveying functionality through intelligent robot coordination and path planning.
Solution Approach 2:
The mobile robots act as intermediaries between assembly stations, performing the conveying function that previously required complex mechanical infrastructure. The robots bridge the gap between different assembly areas using their mobility and navigation capabilities, eliminating the need for fixed conveying mechanisms.
