Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If robotic manipulators are used to convey piece goods to the buffer surface, then the buffering function is achieved, but the system becomes expensive and complex
Solution Approach 1:
The system is divided into independent row pushers, each capable of moving independently along the buffer surface. Each row pusher handles a specific row of containers, allowing the system to be segmented into functional units that can operate autonomously, reducing overall system complexity while maintaining buffering capability
Solution Approach 2:
The row pushers serve multiple functions: they convey containers along the buffer surface, enable selective removal of rows, and can be programmed to adapt to different buffer configurations. This multi-functionality replaces the need for separate robotic manipulators, reducing system complexity while achieving the same buffering objective
2Adaptability or versatility
If guide plates are changed or removed to match row configurations with subsequent packer aisles, then the system can adapt to different configurations, but the operation becomes time-consuming and inefficient
Solution Approach 1:
The row pushers are equipped with programmable drives that allow dynamic adjustment of their movement patterns and destinations. Instead of static guide plates that require physical reconfiguration, the system dynamically adapts by programming the row pushers to deliver rows to different destinations based on real-time packing requirements, maintaining high operational efficiency while achieving configuration adaptability
Solution Approach 2:
The system changes operational parameters (destination assignments, movement speeds, timing) through software programming rather than physical reconfiguration. This allows rapid adaptation to different buffer configurations by modifying control parameters, eliminating the need to stop and reconfigure guide plates, thus maintaining productivity while achieving versatility
3Adaptability or versatility
If multiple rows are buffered and need to be discharged to multiple machines, then the system can handle complex distributions, but coordinating the discharge becomes complex and inefficient
Solution Approach 1:
The discharge function is segmented and assigned to individual row pushers, each responsible for delivering its assigned row to a specific machine. This segmentation eliminates the need for complex centralized coordination, as each pusher independently manages its own discharge timing and destination based on programmed instructions, reducing coordination complexity while maintaining distribution capability
Solution Approach 2:
Each row pusher is equipped with independent programmable drives that enable self-service operation. The pushers autonomously navigate to their destinations, regulate their own speeds, and coordinate discharges based on pre-programmed sequences, eliminating the need for complex external coordination systems while achieving versatile multi-machine distribution

AI summary
The invention relates to a buffer device and a method for buffering unit loads, for example containers, bottles, or packages, comprising a buffer surface (3), a feed device (4) for feeding unit loads to the buffer surface (3), and a discharge device (5) for conveying unit loads from the buffer surface (3). The feed device (4) extends into an inlet area (11) adjacent to the rear end of the buffer surface (3). The discharge device (5) is arranged at the opposite end of the buffer surface (3). Several independently driven, rotating row pushers (7) are provided, which can transport the unit loads (2) through the buffer surface (3) in the transport direction (T). The rotating path of the row pushers is arranged above the buffer surface (3).Both the feed device (4) and the discharge device (5) extend in a direction perpendicular to the transport direction (T) in which the unit loads are moved through the buffer area (3).
