Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate systems are used for hazard detection and operational tasks, then hazard detection capability is improved, but device complexity and cost increase

Engineering Contradiction:
Improvehazard detection capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The autonomous mobile robot is designed to perform multiple functions including hazard detection, navigation, restocking, security, and customer assistance. The single robot platform integrates sensors for hazard detection with operational systems, eliminating the need for separate dedicated hazard detection systems while maintaining comprehensive safety monitoring capabilities throughout the retail environment.

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

Solution Approach 2:

The patent combines hazard detection functionality with the robot's navigation and operational task systems. The processing system integrates data from sensors used for both hazard detection and navigation purposes, merging previously separate systems into a unified platform that reduces overall system complexity and cost.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If autonomous mobile robots are deployed for operational tasks, then productivity is improved, but hazard detection capability deteriorates

Engineering Contradiction:
Improveoperational task performanceVSAvoidhazard detection capability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The robot dynamically adjusts its behavior based on environmental conditions. When hazards are detected, the robot pauses operational tasks to alert personnel and block access to hazardous areas. The system continuously monitors the environment while performing operational tasks, dynamically switching between productivity-focused and safety-focused modes as needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The processing system continuously receives feedback from sensors during operational tasks and uses this information to detect hazards. The system provides real-time feedback by alerting personnel and automatically responding to hazardous conditions, ensuring that productivity operations do not compromise safety monitoring capabilities.

Inventive Principle:
Principle #23Feedback
