Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If computation processing is assigned based on surplus power in facilities, then resource utilization is improved, but facility policies cannot be reflected leading to inappropriate processing assignments

Engineering Contradiction:

Improveresource utilizationVSAvoidprocessing assignment appropriateness

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system introduces feedback by having distributed computing devices send messages containing executability information elements to the management apparatus. This feedback mechanism allows the management apparatus to make informed assignment decisions that reflect both resource availability and facility policies, resolving the contradiction between resource utilization and assignment appropriateness.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The management apparatus acts as an intermediary between facility policies and computation processing assignments. It receives executability information from distributed computing devices and uses this information to mediate the assignment process, ensuring that both resource utilization and policy requirements are satisfied.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If distributed computing devices are placed in respective facilities, then deployment flexibility is improved, but assignment complexity increases due to multiple facility policies

Engineering Contradiction:

Improvedeployment flexibilityVSAvoidassignment complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system extracts the policy reflection requirement from complex multi-facility assignments and encapsulates it in a simple executability information element. This extraction reduces assignment complexity while maintaining the ability to handle multiple facility policies, allowing distributed computing devices to be placed flexibly across facilities.

Inventive Principle:

Principle #2Taking out (Extraction)

3Measurement precision

If executability information is collected from distributed computing devices, then assignment accuracy is improved, but communication overhead increases

Engineering Contradiction:

Improveassignment accuracyVSAvoidcommunication overhead

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

Instead of collecting all possible information from distributed computing devices, the system uses a partial approach by collecting only the essential executability information element. This partial information collection achieves sufficient assignment accuracy while minimizing communication overhead and energy consumption.

Inventive Principle:

Principle #16Partial or excessive action
