Solution Overview

Problem

Conveyor systems, such as elevators, face challenges in efficiently serving both human and robotic passengers, as existing systems do not adequately account for the different priorities and needs of various types of passengers, leading to frustration and inefficiencies.

Innovation Solution

A method and system that generate a control signal for conveyor systems to prioritize service calls based on the priority of robots, determined by their tasks, allowing the conveyor system to manage and allocate resources effectively among multiple passengers, including humans, robots, and other entities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the conveyor system serves human passengers first, then human passenger satisfaction is improved, but robot service efficiency deteriorates

Engineering Contradiction:
Improvehuman passenger satisfactionVSAvoidrobot service efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system changes the service parameter from fixed human-priority to dynamic priority assignment based on robot task urgency. The control entity assigns different priority levels to robot service calls depending on task characteristics, allowing urgent robot tasks to preempt less urgent ones, thereby resolving the contradiction between human satisfaction and robot efficiency

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The priority assignment mechanism transforms the static service order into a dynamic system where priorities are assigned and can be adjusted based on real-time task requirements. This dynamic approach allows the system to adapt service allocation to current needs, balancing human and robot service requirements

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the conveyor system uses a fixed service order, then system simplicity is improved, but service allocation efficiency deteriorates

Engineering Contradiction:
Improvecontrol system simplicityVSAvoidservice allocation efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system introduces priority level parameters to service calls, transforming the simple first-come-first-served model into a parameter-based allocation system. This allows multiple service calls to be differentiated by urgency without requiring complex real-time negotiation, achieving efficient allocation with moderate complexity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The data center automatically assigns priority levels to robot service calls based on task information, eliminating the need for manual priority setting or complex human judgment. The system self-regulates service allocation based on pre-defined priority criteria, improving efficiency while keeping control mechanisms relatively simple

Inventive Principle:
Principle #25Self-service

3Speed

If the conveyor system prioritizes urgent robot tasks, then robot task completion speed is improved, but overall system waiting time increases

Engineering Contradiction:
Improverobot task completion speedVSAvoidoverall system waiting time
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The system applies partial priority boosting to only those robot tasks that are genuinely urgent, rather than giving all robots equal priority or universal priority to all robot tasks. This selective approach ensures that urgent tasks are expedited without causing unnecessary disruptions to the overall service flow, minimizing total waiting time while still achieving fast completion for critical tasks

Inventive Principle:
Principle #16Partial or excessive action
