Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If frequent data transmission is implemented between electric meters and primary stations, then real-time monitoring capability is improved, but data traffic volume increases

Engineering Contradiction:
Improvereal-time monitoring capabilityVSAvoiddata traffic volume
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent introduces a gateway as an intermediary device between the electric meter and the primary station. The gateway collects and caches terminal device information locally, then selectively transmits this information to the primary station in response to downlink requests, rather than requiring continuous bidirectional communication. This mediator role reduces the frequency and volume of data transmissions while maintaining real-time monitoring capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If frequent data transmission is implemented between electric meters and primary stations, then real-time monitoring capability is improved, but power consumption increases

Engineering Contradiction:
Improvereal-time monitoring capabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The gateway acts as a local intermediary that caches terminal device information, eliminating the need for frequent round-trip communications between the electric meter and primary station. By processing and storing data locally, the gateway significantly reduces the communication frequency and associated power consumption while maintaining real-time monitoring capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The gateway performs preliminary data collection and caching operations before the primary station requests information. By having terminal device information readily available in the gateway's cache, the system avoids initiating frequent transmission cycles, thereby reducing power consumption while maintaining real-time monitoring readiness.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If conventional communication protocols are used without information caching, then system simplicity is maintained, but data transmission efficiency decreases

Engineering Contradiction:
Improvesystem simplicityVSAvoiddata transmission efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The gateway introduces a caching mechanism that stores terminal device information locally. This intermediary caching layer enables the system to respond to downlink requests efficiently by retrieving pre-collected information, significantly improving data transmission efficiency without substantially increasing system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
