Solution Overview

Problem

Existing transport systems require modifications or attachments to transported objects, such as turntables, support rods, or grip parts, limiting their ability to handle various types of moving carts or freight without reloading or altering them.

Innovation Solution

A transport robot system that allows multiple robots to collaborate by sandwiching the transported object, using a contact part and rotation mechanism to securely lift and move it without the need for additional attachments, enabling the handling of diverse objects without modification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If turntables or support rods are installed on transported objects, then transport stability is improved, but the transported object cannot be transported without modification

Engineering Contradiction:
Improvetransport stabilityVSAvoidcompatibility with various transported objects
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a turntable as an intermediary component that is integrated into the transport robot itself rather than being attached to the transported object. This mediator enables stable transport by providing a rotational interface between the robot and the object, while the object remains unmodified. The turntable serves as the connecting element that resolves the conflict between needing stability and avoiding modification of the transported object.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If gripping mechanisms are provided for transported objects, then transport reliability is improved, but the transported object cannot be transported without a grip part

Engineering Contradiction:
Improvetransport reliabilityVSAvoidability to handle various object types
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent employs a universal gripping mechanism that can adapt to different object types without requiring specific grip parts on each object. The gripper is designed with multi-functional capabilities to handle various shapes and sizes of transported objects through a single standardized interface, eliminating the need for object-specific modifications while maintaining reliable transport across diverse object types.

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

3Adaptability or versatility

If multiple transport robots collaborate to transport objects, then transport capability is improved, but system complexity increases

Engineering Contradiction:
Improvetransport capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple transport robots into a collaborative system that shares common control architecture and communication protocols. By combining the robots' individual capabilities while maintaining a unified control system, the patent achieves enhanced transport capability for large or heavy objects without proportionally increasing system complexity. The robots work as an integrated team with coordinated movements and shared decision-making.

Inventive Principle:
Principle #5Merging (Combining)
