Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If construction robots use fixed, specialized tools for specific tasks, then task performance reliability is improved, but adaptability to different construction tasks deteriorates

Engineering Contradiction:

Improvetask performance reliabilityVSAvoidadaptability to different construction tasks

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The holding frame is designed with a universal storage battery interface that can accommodate different types of storage batteries and tools. The attachment point on the manipulator allows the same holding frame structure to be used across multiple construction tasks by simply changing the tool module, achieving multi-functionality without redesigning the entire system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system is divided into separable modules: the holding frame, the storage battery interface, and the tool components. This segmentation allows the tool portion to be easily exchanged while keeping the holding frame and manipulator attachment point standardized, enabling quick reconfiguration for different tasks.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If construction robots are designed with high flexibility for multiple tasks, then adaptability is improved, but production cost deteriorates

Engineering Contradiction:

Improveflexibility for different construction tasksVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By designing a universal holding frame with standardized attachment points and storage battery interfaces, the system achieves high adaptability across multiple construction tasks without requiring complex, task-specific robot designs. The same holding frame structure serves multiple purposes with different tool attachments.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The storage battery interface is designed to automatically accommodate different battery types and tools through standardized dimensions and connection protocols, reducing the need for complex adjustment mechanisms or specialized components for each task type.

Inventive Principle:

Principle #25Self-service

3Stability of the object's composition

If tools are permanently fixed to the manipulator, then structural stability is improved, but ease of tool exchange deteriorates

Engineering Contradiction:

Improvestructural stabilityVSAvoidease of tool exchange

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The tool attachment system is segmented into the holding frame and the tool itself, connected through a standardized storage battery interface. This allows the tool to be securely held during operation while enabling easy detachment and exchange by simply releasing the storage battery interface mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment system transitions from a static permanent fixation to a dynamic可拆卸 connection. The holding frame provides stable holding during tool operation through its structural design, while the storage battery interface allows quick release and reattachment for tool exchange without permanent bonding.

Inventive Principle:

Principle #15Dynamics

4Reliability

If the holding frame uses complex fastening mechanisms for secure tool attachment, then reliability of tool fixation is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvetool fixation reliabilityVSAvoidease of tool attachment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The storage battery interface employs a dynamic locking mechanism that automatically secures the tool during insertion and provides reliable fixation during operation, while allowing quick release through a simple release action. This dynamic system transitions between secure locking and easy release states based on operational needs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The storage battery interface is designed with self-latching features that automatically secure the tool upon insertion without requiring complex manual fastening operations. The mechanism self-activates to provide reliable fixation while maintaining ease of attachment and detachment.

Inventive Principle:

Principle #25Self-service
