Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a multi-task network model is used to improve task resolution efficiency and reduce storage costs, then the model structure becomes more complex and requires more computing resources

Engineering Contradiction:
Improvetask resolution efficiencyVSAvoidmodel structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The multi-task network model is divided into a backbone network model that extracts shared features and multiple functional network models that perform specific tasks. This segmentation allows the complex model to be broken down into manageable components, reducing the perceived complexity while maintaining the efficiency benefits of multi-task learning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The backbone network model serves as a universal feature extractor that provides shared intermediate features to multiple functional network models. This multi-functional design allows a single model structure to handle multiple tasks simultaneously, improving productivity while managing complexity through resource sharing.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of substance

If a multi-task network model is deployed on mobile devices to reduce storage costs, then computing resources on mobile devices become insufficient

Engineering Contradiction:
Improvestorage costsVSAvoidcomputing resources on mobile device
Core Design Contradiction:
Loss of substanceVSUse of energy by moving object

Solution Approach 1:

A communication apparatus is introduced as an intermediary between the mobile device and the cloud. The communication apparatus receives intermediate features from the mobile device, performs additional processing, and returns results. This intermediary approach allows the system to leverage cloud computing resources while maintaining the storage efficiency benefits of multi-task learning on mobile devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the multi-task network model is divided between mobile device and cloud for device-cloud collaboration, then transmission overheads increase due to complex model structures

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

Only the essential intermediate features extracted by the backbone network model are transmitted between the mobile device and the cloud, rather than transmitting the entire complex model structure or raw data. This extraction approach minimizes transmission overhead while maintaining the collaborative processing benefits between device and cloud.

Inventive Principle:
Principle #2Taking out (Extraction)
