Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional data transfer methods are used between hardware devices, then data can be transferred between devices, but significant memory and computing resources are consumed

Engineering Contradiction:

Improvememory and computing resourcesVSAvoiddata transfer efficiency

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The patent introduces a routing system that acts as an intermediary to manage and optimize data transfers between hardware devices. This routing system determines optimal paths and coordinates transfers, reducing the need for excessive memory and computing resources by efficiently managing the transfer process rather than allowing direct, resource-intensive device-to-device transfers

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements dynamic routing that adapts to current system conditions, device availability, and resource states. The routing decisions are made in real-time based on current system state, allowing the system to optimize resource usage dynamically rather than following static transfer paths, thereby reducing overall memory and computing resource consumption

Inventive Principle:

Principle #15Dynamics

2Loss of time

If traditional data transfer methods are used between hardware devices, then data can be transferred between devices, but significant time is consumed

Engineering Contradiction:

Improvedata transfer timeVSAvoiddata transfer speed

Core Design Contradiction:

Loss of timeVSProductivity

Solution Approach 1:

The patent performs preliminary routing analysis and path determination before actual data transfers occur. The system pre-evaluates available paths, device capabilities, and resource states to establish optimal transfer routes in advance, reducing the time required during actual data transfer operations by avoiding runtime decision-making

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The routing system serves as an intermediary that coordinates and manages data transfers, optimizing paths and timing to reduce transfer time. By centralizing control and making intelligent routing decisions, the system minimizes delays and inefficiencies associated with traditional direct transfer methods

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If simple routing strategies are used, then implementation is straightforward, but optimal data transfer paths are not achieved

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The routing system operates autonomously, automatically determining optimal data transfer paths without requiring manual configuration or complex user input. The system self-manages routing decisions based on device topology and resource states, maintaining ease of operation while achieving optimal transfer paths through automated intelligence

Inventive Principle:

Principle #25Self-service
