Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the processor performance is improved to achieve high performance and precision operation, then the operation performance is improved, but the manufacturing cost and power consumption increase

Engineering Contradiction:
Improveoperation performanceVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent introduces an edge server as an intermediary between the end device and the cloud server. The edge server performs data processing and control command generation, while the end device only needs to execute received commands. This mediator approach allows the end device to maintain low processing power while still achieving high-performance operations through externally provided control commands.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the processor performance is improved to achieve high performance and precision operation, then the operation performance is improved, but the manufacturing cost increases

Engineering Contradiction:
Improveoperation performanceVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The edge server acts as an external brain for the end device, providing sophisticated processing capabilities without requiring expensive high-performance processors in the end device itself. This separates the complex processing functions from the physical device, enabling low-cost manufacturing while maintaining high operational performance through cloud-based intelligence.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the processor performance is increased to achieve high performance and precision, then the operation performance is improved, but the size of the processor increases

Engineering Contradiction:
Improveoperation performanceVSAvoidprocessor size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The edge server provides the computational brain externally, allowing the end device to remain compact with minimal local processing hardware. The processor in the end device only needs to handle basic command execution and sensor data transmission, keeping it small while the bulk of the processing intelligence resides in the remotely located edge server.

Inventive Principle:
Principle #24Intermediary (Mediator)
