Solution Overview

Problem

Manual removal and replacement of bins in sorting units lead to substrate damage and decreased throughput due to potential overloading and delayed bin exchange in rotary sorters.

Innovation Solution

A bin handler with end effectors is integrated into the sorting unit to automate the removal and replacement of bins, allowing for continuous sorting by determining full bins and swapping them with empty ones using a controller-assisted system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual bin removal and replacement is used, then device complexity is reduced, but substrate damage increases and throughput decreases

Engineering Contradiction:
Improvebin handling mechanismVSAvoidsubstrate damage prevention
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The bin handler system operates autonomously to detect full bins and perform exchanges without human intervention. The controller monitors bin fill levels and automatically activates the bin handler mechanism, allowing the system to service itself and eliminate substrate damage caused by manual handling delays

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations with an automated bin handler mechanism controlled by electronic sensors and controllers. This substitution eliminates the variability and delays inherent in manual bin handling, ensuring consistent and timely bin exchanges that prevent substrate damage

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If manual bin removal and replacement is used, then device complexity is reduced, but productivity decreases

Engineering Contradiction:
Improvebin handling mechanismVSAvoidthroughput
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The automated bin handler enables continuous sorting operations by eliminating downtime associated with manual bin exchanges. The system maintains continuous operation by automatically detecting full bins and replacing them with empty bins without halting the sorting process, thereby maximizing throughput

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system autonomously manages bin exchanges through integrated sensors and automated handling mechanisms, eliminating the need for operator intervention and associated downtime. This self-service capability ensures uninterrupted sorting operations and maximizes productivity

Inventive Principle:
Principle #25Self-service

3Reliability

If automated bin handler is integrated, then substrate damage decreases, but device complexity increases

Engineering Contradiction:
Improvesubstrate damage preventionVSAvoidbin handling mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bin handler mechanism serves multiple functions: detecting full bins, removing full bins, positioning empty bins, and loading empty bins. This multi-functionality consolidates what would otherwise require separate systems into a single integrated mechanism, reducing overall system complexity while maintaining substrate damage prevention

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The controller acts as an intermediary that coordinates between sensors detecting bin fill levels and the bin handler mechanism. This centralized control simplifies the system architecture by providing a single point of coordination rather than requiring direct connections between multiple independent components

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If automated bin handler is integrated, then productivity increases, but device complexity increases

Engineering Contradiction:
ImprovethroughputVSAvoidbin handling mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines bin detection, bin removal, bin positioning, and bin loading functions into a single integrated bin handler system. This merging of functions achieves high productivity through automated continuous operation while reducing the complexity that would result from having separate systems for each function

Inventive Principle:
Principle #5Merging (Combining)

AI summary

In one example, a sorting unit includes a sorting system and a plurality of bins into which substrates are sorted. The sorting unit includes a bin handler having a first end effector for receiving one bin of the plurality of bins, and second end effector for disposing an empty bin in the previous location of the received bin. In one example, a method of operating a sorting unit is also provided.
