Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cloud-based communication is used for data transmission, then data synchronization can be achieved across far-field devices, but synchronization delay increases and power consumption rises

Engineering Contradiction:
Improvedata transmission coverageVSAvoidsynchronization delay
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent introduces a dual-path communication architecture where cloud servers act as intermediaries for far-field device communication, while near-field devices communicate directly peer-to-peer. This intermediary approach enables wide coverage through cloud routing while maintaining low latency for local devices that bypass the cloud intermediate step.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the communication network into near-field and far-field zones, applying different transmission protocols to each segment. Near-field segments use direct device-to-device communication for low latency, while far-field segments utilize cloud-based routing, optimizing the trade-off between coverage and synchronization delay for each segment.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If cloud-based communication is used for data transmission, then data synchronization can be achieved across far-field devices, but power consumption increases

Engineering Contradiction:
Improvedata transmission coverageVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The cloud server acts as an intermediary that enables far-field communication without requiring continuous high-power transmissions from mobile devices. Devices can enter low-power states when communicating through the cloud intermediary, reducing their own power consumption while maintaining connectivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication system is segmented into power-efficient near-field direct communication and cloud-mediated far-field communication. This segmentation allows devices to select the lower-power direct communication mode when possible, reserving cloud-based transmission only when necessary for distant devices.

Inventive Principle:
Principle #1Segmentation

3Loss of time

If device-to-device communication is used for near-field connections, then synchronization delay is reduced, but transmission range is limited

Engineering Contradiction:
Improvesynchronization delayVSAvoidtransmission range
Core Design Contradiction:
Loss of timeVSLength of moving object

Solution Approach 1:

The patent merges direct device-to-device communication and cloud-based communication into a unified hybrid architecture. Near-field devices utilize direct communication for low latency, while the cloud infrastructure is merged in as a fallback and extension mechanism to expand transmission range without significantly impacting overall system performance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent adds the cloud communication dimension to the traditional direct device communication model. This dimensional expansion allows the system to reach far-field devices by routing through the cloud dimension, while maintaining the original direct communication path for near-field devices to preserve low latency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Device complexity

If traditional data transmission methods are used, then implementation is simple, but data transmission efficiency is poor in collaborative scenarios

Engineering Contradiction:

Solution Approach 1:

The patent implements dynamic transmission method selection that automatically adapts to collaborative scenario conditions. The system dynamically switches between direct and cloud-based communication modes based on real-time factors such as device proximity, network conditions, and collaboration requirements, optimizing transmission efficiency without requiring complex manual configuration.

Inventive Principle:
