Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional non-intelligent discharge systems are used, then energy storage capacity can be maintained, but system efficiency deteriorates due to upstream mismatches and lack of level sensitivity

Engineering Contradiction:
Improvefuel consumptionVSAvoidintelligence of charge/discharge control
Core Design Contradiction:
Loss of energyVSExtent of automation

Solution Approach 1:

The patent implements a control system that continuously monitors power demand, state of charge, and timing information, then adjusts charge/discharge operations in real-time. This feedback mechanism enables the system to respond to changing load conditions and align power delivery with actual demand, eliminating the upstream mismatches that cause energy loss in traditional systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system autonomously manages its own charge/discharge operations without external control. The control computer automatically receives timing information, determines optimal charge/discharge moments based on power demand and state of charge, and executes operations independently. This self-service capability eliminates the need for manual intervention while optimizing efficiency through intelligent decision-making.

Inventive Principle:
Principle #25Self-service

2Reliability

If large energy storage capacity is used, then power supply stability is improved, but system cost increases due to larger storage requirements

Engineering Contradiction:
Improvepower supply stabilityVSAvoidenergy storage capacity
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The system performs charge operations in advance during periods of low power demand or low cost, storing energy before peak demand periods. By proactively charging during off-peak times and discharging during peak times, the system maintains power supply stability without requiring excessively large storage capacity, as the timing optimization maximizes the utility of stored energy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamic charge/discharge control that continuously adapts to changing conditions. Rather than using fixed, oversized storage capacity, the system dynamically adjusts its operations based on real-time power demand, state of charge, and timing information. This dynamic approach allows smaller storage systems to maintain reliability by optimizing when energy is stored and released.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If simple timer-based charge windows are used, then system complexity is reduced, but productivity deteriorates due to inability to capture brief load fluctuations

Engineering Contradiction:
Improvecharge control systemVSAvoidefficiency of power management
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The control system receives continuous feedback about power demand, state of charge, and timing information, then adjusts charge/discharge operations accordingly. This feedback enables the system to capture brief load fluctuations that simple timer-based systems miss, improving productivity while maintaining manageable complexity through automated decision-making algorithms.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces simple mechanical timer-based control with an intelligent control computer that processes information and makes decisions based on multiple parameters. This substitution of mechanical timing mechanisms with electronic information processing enables the system to respond to complex, varying conditions without proportionally increasing physical complexity, as the control logic is implemented through software algorithms.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Productivity

If fast sample rate charge/discharge control is implemented, then system efficiency is improved, but measurement and control difficulty increases

Engineering Contradiction:
Improveefficiency of power managementVSAvoidpower demand monitoring
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The control computer serves as an intermediary that receives and processes timing information, power demand data, and state of charge information. It synthesizes these multiple information streams and translates them into control signals for the energy storage system. This intermediary role simplifies the measurement and control tasks by centralizing data processing and decision-making in a single control unit rather than requiring distributed complex measurement systems.

Inventive Principle:
Principle #24Intermediary (Mediator)
