Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional communication tools (cell phones) are used for dispatching commands, then the system can operate with simple equipment, but the communication quality is poor and information exchange is not timely

Engineering Contradiction:

Improvesimplicity of equipmentVSAvoidcommunication quality

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces conventional mechanical/electronic communication tools (cell phones) with a 3G multimedia communication system that uses digital signal processing, packet switching, and integrated services to achieve superior communication quality while maintaining operational simplicity through standardized interfaces

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system transitions from 2G to 3G communication technology, changing fundamental parameters such as transmission mode (from circuit switching to packet switching), data rate capabilities, and service integration to achieve simultaneous improvement in communication quality and functionality

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If conventional communication tools are used, then the system structure is simple, but the information exchange is not in real time and allocation is not timely

Engineering Contradiction:

Improvesystem structureVSAvoidinformation exchange time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The system establishes preliminary action through real-time data exchange protocols and pre-configured communication channels that enable immediate information transfer and decision-making, eliminating delays in information exchange and resource allocation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The 3G multimedia communication system provides continuous real-time data transmission capabilities, ensuring that information exchange and coordination actions occur without interruption or delay, thereby eliminating time loss in the dispatching command process

Inventive Principle:

Principle #20Continuity of useful action

3Quantity of substance

If conventional communication tools are used, then the cost is high, but the communication coverage is limited and requires many factors such as weather and geographical position

Engineering Contradiction:

Improvecommunication coverageVSAvoidweather and geographical position influence

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent introduces 3G network infrastructure as an intermediary communication layer that mediates between users and the dispatching command system, providing robust communication coverage that is independent of weather conditions and geographical position through distributed network nodes and signal relay mechanisms

Inventive Principle:

Principle #24Intermediary (Mediator)

4Duration of action of moving object

If conventional communication tools are used, then the equipment is simple, but the conversation time is limited and tone quality is poor

Engineering Contradiction:

Improveconversation timeVSAvoidtone quality

Core Design Contradiction:

Duration of action of moving objectVSEase of operation

Solution Approach 1:

The system changes fundamental communication parameters by implementing 3G multimedia services that support longer conversation durations with maintained quality through advanced error correction, signal processing, and adaptive bitrate streaming technologies

Inventive Principle:

Principle #35Parameter changes
