Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If traditional network architectures are used for machine automation, then system integration is achieved, but latency is high and bandwidth is low

Engineering Contradiction:
Improvenetwork transmission speedVSAvoidnetwork latency
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The network architecture is segmented into multiple functional layers including physical layer, data link layer, network layer, and application layer, with each layer optimized independently. This segmentation allows high-speed physical layer transmission while maintaining complex protocol handling at higher layers, resolving the contradiction between transmission speed and protocol complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A network controller acts as an intermediary device that manages data flow between end devices and the network core. The controller buffers, prioritizes, and forwards packets efficiently, reducing latency while maintaining high throughput. This intermediary layer decouples the speed requirements of individual devices from the overall network performance.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If copper cabling systems are used for network transmission, then electrical connectivity is achieved, but electromagnetic interference is significant and shielding costs are high

Engineering Contradiction:
Improveelectromagnetic interferenceVSAvoidcabling complexity and shielding requirements
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces traditional electrical copper cabling with optical fiber transmission media. Optical fibers transmit data as light signals instead of electrical signals, completely eliminating electromagnetic interference and the need for expensive shielding. This substitution maintains transmission functionality while removing the harmful electromagnetic effects and associated complexity.

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

3Productivity

If dynamic bandwidth allocation is implemented, then transmission efficiency is improved, but control mechanism complexity increases

Engineering Contradiction:
Improvenetwork throughputVSAvoidbandwidth allocation mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The dynamic bandwidth allocation mechanism incorporates feedback loops where network controllers continuously monitor traffic conditions, queue depths, and transmission rates. Based on this feedback, the controllers dynamically adjust allocation parameters such as time slot sizes and transmission priorities. This feedback-driven approach achieves high productivity while keeping the control mechanism manageable through automated adaptation rather than complex manual configuration.

Inventive Principle:
Principle #23Feedback
