Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual estimation by operator is used to track inventory, then device complexity is reduced, but measurement precision and reliability deteriorate due to human error and safety concerns

Engineering Contradiction:
Improvetracking system complexityVSAvoidinventory estimation accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces manual mechanical estimation with automated sensor-based measurement systems. On-board sensors in transporting vehicles automatically measure inventory volume and weight, while aerial vehicles use scanning systems to detect storage location inventory levels. This substitution eliminates human error and improves measurement precision while reducing operational complexity through automation.

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

Solution Approach 2:

The tracking system enables self-service inventory monitoring where transporting vehicles and aerial vehicles automatically perform measurements and transmissions without human intervention. The system uses the vehicles' own onboard sensors and communication capabilities to autonomously track inventory, eliminating the need for manual operators and improving both accuracy and safety.

Inventive Principle:
Principle #25Self-service

2Device complexity

If manual inventory estimation is performed, then device complexity is reduced, but productivity and time consumption worsen due to time-consuming estimations

Engineering Contradiction:
Improvetracking system complexityVSAvoidinventory tracking efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent replaces time-consuming manual estimation with automated sensor-based measurement systems. On-board sensors in transporting vehicles automatically measure inventory volume and weight during transport, while aerial vehicles use scanning systems to rapidly detect storage location inventory levels. This automation dramatically increases productivity and reduces time consumption compared to manual methods.

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

Solution Approach 2:

The automated measurement system enables continuous inventory tracking as vehicles move through storage locations and transport inventory. The on-board sensors and aerial scanning systems operate continuously during vehicle operations, providing real-time inventory data without interruption, thereby improving productivity and eliminating downtime associated with manual counting.

Inventive Principle:
Principle #20Continuity of useful action

3Device complexity

If manual estimation is used in complex work site environments, then device complexity is reduced, but reliability worsens due to safety concerns and estimation variations

Engineering Contradiction:
Improvetracking system complexityVSAvoidinventory estimation consistency
Core Design Contradiction:

Solution Approach 1:

The patent replaces manual estimation with automated sensor-based measurement systems that provide consistent and reliable inventory tracking. On-board sensors in transporting vehicles automatically measure inventory volume and weight with high precision, while aerial vehicles use scanning systems to detect storage location inventory levels. This automation eliminates the variations in quality and consistency associated with manual estimation, improving reliability while maintaining safety by removing operators from hazardous environments.

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

Solution Approach 2:

The tracking system enables self-service inventory monitoring where transporting vehicles and aerial vehicles automatically perform measurements and transmissions without human intervention. The system uses the vehicles' own onboard sensors and communication capabilities to autonomously track inventory, eliminating the need for manual operators and improving both accuracy and safety.

AI summary

The invention relates to a method performed by a monitoring unit (70) for tracking inventory at a work site (1). The inventory is stored in a plurality of storage locations (10, 11, 12). The method comprises receiving at least one first measurement result of the inventory from at least one transporting vehicle (30, 31, 32). The at least one first measurement result is indicative of at least part of the inventory (20, 21, 22) transported to, from, and/or between the plurality of storage locations (10, 11, 12) in the work site (1). The at least one first measurement result is measured by an on-board sensor of the at least one transporting vehicle (30, 31, 32). The at least one first measurement result comprises at least one volume measurement result, and/or at least one weight measurement result. The method further comprises estimating an amount of the inventory based on the received at least one first measurement result.
