Solution Overview

Problem

Robotic systems lack the sophistication to duplicate human sensitivity and adaptability for executing complex and intricate tasks, particularly in packing objects within containers, due to limitations in granularity of control and flexibility, as well as the inability to account for real-world deviations and uncertainties.

Innovation Solution

A robotic system with dynamic pack adjustment mechanisms that generates discretized models of packing components, derives packing plans to stack objects with precise placement locations and separation distances, and dynamically adjusts plans to account for unexpected container conditions using sensors and real-time data to ensure efficient and flexible object placement.

1Extent of automation

If traditional robotic systems are used for packing objects, then automation is achieved, but the system lacks flexibility and adaptability to account for real-world deviations and uncertainties

Engineering Contradiction:
ImproveautomationVSAvoidflexibility
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The robotic system dynamically adjusts packing plans in real-time based on sensor feedback and actual container conditions. The system transitions from static pre-programmed packing sequences to dynamic adaptive planning, allowing the robot to respond to deviations such as container irregularities, object position variations, and stacking uncertainties while maintaining automation.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If precise control is implemented for object placement, then packing precision is improved, but the system complexity increases

Engineering Contradiction:
Improveplacement precisionVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system employs sensor feedback mechanisms to detect actual object positions, container conditions, and packing status in real-time. This feedback is fed back to the control system, which adjusts placement parameters and generates corrected motion plans, achieving precise control through closed-loop control rather than overly complex open-loop systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The robotic system dynamically modifies packing parameters such as placement positions, orientations, and sequencing based on real-time conditions. By changing parameters adaptively rather than using fixed complex control algorithms, the system achieves precision while managing complexity through parameter optimization.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If dynamic adjustment mechanisms are added to account for real-world deviations, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The robotic system performs self-adjustment by autonomously detecting deviations through sensors and automatically generating corrected packing plans without requiring external intervention or complex manual reconfiguration. The system serves itself by adapting to real-world conditions, reducing the need for overly complex external control mechanisms.

Inventive Principle:
Principle #25Self-service
