Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sortation systems are inefficient and inflexible, requiring a large number of collection bins and human labor, leading to high costs and limited throughput, as they struggle to handle a variety of object sizes and weights effectively.
Innovation Solution
An automated shuttle sorter system that includes a movable carriage for transporting objects between multiple destination stations, using robotic manipulators and learning algorithms to dynamically assign objects to collection bins based on object identification and historical usage patterns, reducing the need for manual intervention and optimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of collection bins are used to handle diverse objects, then the system can accommodate more object types and destinations, but the physical space, capital costs, and operating costs increase significantly
Solution Approach 1:
The patent implements dynamic bin assignment where collection bins are not permanently dedicated to specific destinations but are temporarily assigned based on real-time sortation needs. The system controller dynamically reconfigures which bin receives objects for which destination, allowing the same physical bin to serve multiple destinations sequentially. This dynamic approach enables the system to handle diverse object types and destinations with fewer physical bins, directly resolving the contradiction between adaptability and physical space requirements
Solution Approach 2:
The patent introduces a time dimension to the sortation process by implementing multi-pass sortation. Instead of requiring all destinations to be simultaneously accessible (spatial dimension only), the system allows objects to be sorted in multiple passes where different destination sets are active at different times. Objects can be held in intermediate storage and re-sorted in subsequent passes, effectively adding a temporal dimension that expands system capacity without increasing physical footprint
2Adaptability or versatility
If human workers perform sortation manually, then the system is flexible in handling various objects, but the throughput is limited by worker speed
Solution Approach 1:
The patent implements automated object identification and routing where the system itself performs the sortation decision-making and execution. Scanners automatically identify objects and their destinations, the controller automatically determines optimal bin assignments, and actuators automatically divert objects to correct bins. This self-service automation eliminates human labor constraints on throughput while maintaining flexibility through programmable sortation logic that can adapt to different object types and routing rules
Solution Approach 2:
The patent replaces manual human sortation with an automated control system that uses optical scanning, computer processing, and mechanical actuators. Instead of human workers visually identifying and physically moving objects, the system uses scanners to detect objects, processors to determine routing, and automated divert mechanisms to transport objects. This substitution dramatically increases throughput while maintaining adaptability through software-configurable sortation rules
3Productivity
If recirculating conveyors with tilt trays are used for automation, then throughput increases, but the system requires objects to have visible identifying codes and follows an inflexible sequence
Solution Approach 1:
The patent implements dynamic sortation sequences where the processing order is not fixed but adapts based on object characteristics, destination requirements, and system state. The controller can dynamically adjust which objects are sorted first, which destinations are prioritized, and how objects are grouped, allowing flexible processing sequences that optimize throughput for different scenarios rather than following a rigid predetermined sequence
Solution Approach 2:
The patent creates a universal sortation system that can handle multiple object types, sizes, weights, and destination configurations through a single flexible platform. The system uses adaptive bin assignment and multi-pass sortation capabilities to accommodate diverse object characteristics without requiring dedicated processing lines for each object type, making the system universally applicable to various sortation scenarios while maintaining high throughput
4Adaptability or versatility
If the number of diverts is increased to handle more destinations, then more object types can be sorted, but the mechanical complexity and cost per divert increase significantly
Solution Approach 1:
The patent merges multiple divert functions into shared mechanical infrastructure. Instead of each destination having its own dedicated divert mechanism, the system uses a common conveyor backbone with shared actuators and control systems that can direct objects to multiple destinations. The dynamic bin assignment approach allows the same physical divert location to serve different destinations at different times, effectively merging multiple divert functions into fewer physical components, reducing mechanical complexity while maintaining high destination capacity
