Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a robot is designed to provide only a specific service, then the service quality can be optimized, but the utilization efficiency and cost-effectiveness deteriorate

Engineering Contradiction:
Improveservice qualityVSAvoidservice variety
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The robot system is divided into a mobile platform and detachable functional modules (porter module, cleaning module, etc.). Each module can be independently attached or detached based on service requirements, allowing the system to provide specific services with optimized performance while maintaining versatility through module replacement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mobile robot platform is designed with universal interfaces and coupling mechanisms that can accommodate multiple types of functional modules. This enables a single platform to perform various services (transportation, cleaning, delivery) by simply changing the attached module, thereby improving both service quality and utilization efficiency.

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

2Device complexity

If manual operation is used to provide services at specific positions, then the robot structure can be simpler, but the usability and service efficiency deteriorate

Engineering Contradiction:
Improverobot structureVSAvoidservice accessibility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The robot is equipped with automatic navigation and obstacle detection systems that enable it to autonomously move to designated positions and perform services without human intervention. The depth sensor and control unit work together to detect obstacles and automatically adjust the robot's path, providing convenient service access while maintaining relatively simple overall structure.

Inventive Principle:
Principle #25Self-service

3Device complexity

If manual navigation is required to reach service positions, then the control system can be simpler, but the service efficiency and user experience deteriorate

Engineering Contradiction:
Improvecontrol systemVSAvoidservice efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The robot replaces manual mechanical navigation with an automatic control system that uses depth sensors to detect obstacles and a control unit to process spatial information and generate navigation commands. This substitution enables autonomous movement to service positions, significantly improving service efficiency while the modular architecture keeps the overall control system manageable.

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