Sorting Aisle Layout for More Destinations in Limited Floor Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sorting systems in e-commerce and logistics face inflexibility and increased costs due to the need for expanding confined areas to accommodate a high number of destinations, which are not geometrically proportional to the number of destinations, leading to inefficiencies and higher operational expenses.
Innovation Solution
A sorting system and method utilizing autonomous mobile robots that can switch between collaborative and non-collaborative modes, equipped with safety devices to adapt speed and conveyor operation based on zone type, allowing high productivity in non-human-accessible areas while maintaining safety in collaborative zones, and utilizing a sorting aisle to increase destination points without enlarging the plant size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the perimeter of the confined area is expanded to accommodate more destinations, then the number of destinations increases, but the area of the confined area extends in geometric proportion leading to increased costs
Solution Approach 1:
The patent introduces a collaborative zone that extends the sorting system into a new spatial dimension beyond the traditional confined area perimeter. Robots can access destinations from the collaborative zone side, effectively adding a new dimension to the sorting architecture. This allows destinations to be accessed from multiple directions (inside the confined area and from the collaborative zone), reducing the need for peripheral expansion and enabling linear rather than geometric growth in area requirements.
2Productivity
If non-collaborative robots are used in confined areas to maximize productivity, then sorting productivity increases, but the system becomes inflexible and cannot adapt to varying operational needs
Solution Approach 1:
The patent employs universal robots capable of operating in both collaborative and non-collaborative modes depending on their location. Robots equipped with safety systems can function as non-collaborative robots within the confined area for high-speed sorting, then transition to collaborative mode when entering the collaborative zone to interact with human operators. This multi-functionality allows the same robot fleet to maximize productivity in confined areas while maintaining system flexibility and adaptability through collaborative operations.
Solution Approach 2:
The system dynamically adjusts robot operating modes based on spatial context. Robots automatically switch between non-collaborative mode (high speed, confined area) and collaborative mode (lower speed, human-accessible zones) depending on their current location and task requirements. This dynamic adaptation enables the system to optimize productivity in confined areas while maintaining flexibility when operational conditions change, resolving the contradiction between fixed high-productivity operation and adaptive versatility.
3Reliability
If collaborative robots with safety devices and speed thresholds are used in shared areas, then safety is maintained, but productivity is reduced due to speed limitations
Solution Approach 1:
The patent applies different operational characteristics to different spatial zones. Within the confined area, robots operate in non-collaborative mode with higher speeds optimized for productivity. When entering the collaborative zone, robots automatically activate safety devices and reduce speed to collaborative thresholds. This local differentiation of operational quality allows the system to achieve high productivity in the confined sorting area while maintaining safety in human-accessible collaborative zones, resolving the contradiction between safety and productivity.
