Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a battery is used to provide power for the meter, then the meter can operate during power outages, but the battery life is reduced due to inability to handle short intense power surges

Engineering Contradiction:
Improvemeter operation during power outagesVSAvoidbattery life
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent combines a battery and a supercapacitor into a hybrid power supply system. The supercapacitor handles short-term power surges during data transmission, while the battery provides sustained power during outages. This merging allows the system to leverage the high power density of supercapacitors and the high energy density of batteries, resolving the contradiction between reliability during outages and battery life.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The supercapacitor acts as an intermediary between the battery and the meter's power consumption. It buffers the power surges required for data transmission, preventing direct draws from the battery. This intermediary role protects the battery from damaging surge currents while ensuring the meter receives adequate power during outages.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the meter relies on battery power alone, then the system is simple, but data transmission may fail during power surges

Engineering Contradiction:
Improvepower supply systemVSAvoiddata transmission integrity
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent merges a battery with a supercapacitor module to create a hybrid power system. The supercapacitor specifically addresses data transmission power demands by providing immediate surge current, ensuring transmission reliability. While this increases device complexity slightly, the modular design keeps the implementation practical.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If the battery supplies all power demands including data transmission surges, then the system is simple, but the battery deteriorates faster

Engineering Contradiction:
Improvepower supply configurationVSAvoidbattery longevity
Core Design Contradiction:
Device complexityVSDuration of action of stationary object

Solution Approach 1:

The supercapacitor serves as a mediator that absorbs the high-current demands of data transmission. By placing the supercapacitor between the battery and the transmission circuitry, the battery is protected from damaging surge currents that would otherwise accelerate its deterioration. This intermediary approach extends battery longevity while maintaining system simplicity through modular integration.

Inventive Principle:
Principle #24Intermediary (Mediator)
