Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional skid or slat-chain conveying systems are used for interior trim line and exterior assembly line, then the assembly line can maintain stable operation, but the civil foundation requires special structure leading to high investment and difficulty in reformation or capacity expansion
Solution Approach 1:
The patent replaces fixed mechanical conveying systems with mobile robots that can dynamically adapt their positions and paths. The robots move on the floor without requiring fixed civil foundations, enabling flexible reconfiguration of assembly lines for different models and capacities while maintaining operational reliability through automated control.
Solution Approach 2:
The patent substitutes traditional mechanical conveying systems (skid or slat-chain) with autonomous mobile robots. This replacement eliminates the need for complex civil foundations and mechanical conveying infrastructure, reducing investment while improving adaptability through software-controlled navigation and positioning.
2Ease of manufacture
If fixture mechanical conveying line is used to create lower body operating platform, then the assembly line can be formed, but the fixed form and high initial investment make subsequent modification and maintenance highly difficult
Solution Approach 1:
The patent employs mobile robots that can dynamically reposition themselves to form different operating platforms and assembly configurations. This eliminates fixed fixture structures, allowing easy modification and maintenance by simply reprogramming robot paths and positions rather than physically modifying infrastructure.
Solution Approach 2:
The mobile robots serve multiple functions: they can form lower body operating platforms, interior trim assembly lines, and exterior assembly lines by reconfiguring their positions and协作 relationships. This universal capability replaces multiple dedicated fixed fixture systems, easing both manufacture and modification.
3Productivity
If traditional final assembly workshop is designed with fixed civil foundation and mechanical conveying form, then the assembly process can be standardized, but it is difficult to accommodate to the needs for fast response to existing markets and rapid update of vehicle models
Solution Approach 1:
The patent creates a dynamic assembly system where mobile robots can be rapidly repositioned and reprogrammed to accommodate different vehicle models and production requirements. This maintains standardized assembly processes through automated workflows while enabling fast response to market changes without fixed infrastructure constraints.
Solution Approach 2:
The system enables rapid parameter changes by modifying robot navigation paths, positioning coordinates, and assembly instructions through software rather than physical infrastructure changes. This allows standardization to be maintained while adapting quickly to different models and market demands.
4Device complexity
If large plate line for interior trims and through mechanical conveying line are omitted, then investment and construction period are reduced, but the assembly efficiency needs to be maintained through alternative methods
Solution Approach 1:
The patent replaces complex mechanical conveying lines with autonomous mobile robots that navigate and position themselves using sensors and control systems. This substitution simplifies the mechanical infrastructure while maintaining or improving assembly efficiency through automated, programmable operations and flexible task allocation.
Solution Approach 2:
The mobile robots are self-propelled and self-navigating, eliminating the need for external mechanical conveying systems. Each robot independently positions itself and performs assembly tasks, maintaining productivity while dramatically reducing device complexity and infrastructure requirements.
