Solution Overview

Problem

Inefficient human operator utilization and congestion arise in warehouse environments where robots and humans work together due to lack of direction, leading to increased dwell time and reduced efficiency.

Innovation Solution

A robot-assisted personnel routing system that includes autonomous robots providing task recommendations to human operators based on efficiency factors, such as dwell time, proximity, and congestion, using interactive graphics on a display to guide operators to the most efficient next task.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If human operators work autonomously without direction in a shared navigational space with robots, then operators have freedom of movement, but operator utilization efficiency decreases and congestion increases

Engineering Contradiction:
Improveoperator freedomVSAvoidoperator utilization efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system implements real-time feedback by continuously monitoring robot status information (dwell time, location, task completion) and providing dynamic recommendations to operators through the user interface. This feedback loop enables operators to adjust their movements and task selection based on current system state, resolving the contradiction between operational freedom and efficiency by guiding operators toward high-priority robots without restricting their autonomy.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Operators serve themselves by independently selecting and navigating to robots based on system recommendations, rather than being assigned tasks centrally. The system provides the information needed for operators to make informed decisions autonomously, improving utilization efficiency while maintaining operator independence and freedom of movement.

Inventive Principle:
Principle #25Self-service

2Device complexity

If human operators wait for robots or guess directions to find tasks, then operators maintain simple behavior, but time is wasted and efficiency reduces

Engineering Contradiction:
Improveoperator behavior complexityVSAvoidoperator idle time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-calculating and presenting recommended robots and tasks to operators before operators need to make decisions. The system monitors robot status in real-time and proactively provides guidance on which robots need assistance, eliminating the need for operators to wait or guess, thereby reducing idle time without significantly increasing operational complexity.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple operators pursue the same robot without coordination, then operators independently select tasks, but time is wasted traveling to the same robot and reconciling conflicts

Engineering Contradiction:
Improveoperator independenceVSAvoidconflict resolution time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system provides real-time feedback on operator assignments and robot status to all operators through the user interface. When an operator is assigned to or selects a robot, this information is immediately visible to other operators, allowing them to adjust their choices and avoid pursuing the same robot. This feedback mechanism maintains operator independence while preventing conflicts and wasted travel time.

Inventive Principle:
Principle #23Feedback

4Extent of automation

If robots operate without personnel routing assistance, then robots maintain autonomous operation, but dwell time increases and efficiency decreases

Engineering Contradiction:
Improverobot autonomyVSAvoidorder fulfillment efficiency
Core Design Contradiction:
Extent of automationVSProductivity

Solution Approach 1:

The system acts as an intermediary between autonomous robots and human operators, translating robot needs into operator recommendations and coordinating task allocation. Robots maintain their autonomy in navigating and executing tasks, while the intermediary system optimizes the human-robot collaboration by directing operators to robots with highest dwell times or most urgent tasks, thereby improving overall efficiency without reducing robot autonomy.

Inventive Principle:
Principle #24Intermediary (Mediator)
