Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If energy is distributed through separate heating and electricity grids, then each grid can be independently managed, but energy utilization efficiency deteriorates due to inability to balance supply and demand across grids

Engineering Contradiction:
Improveenergy utilization efficiencyVSAvoidenergy grid management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the management of heating grid and electricity grid into a unified control system that coordinates heat sources across both grids. The controller integrates supply and demand data from both grids and automatically adjusts heat distribution to optimize overall energy utilization, transforming two independent grid management systems into a coordinated multi-grid energy management system.

Inventive Principle:
Principle #5Merging (Combining)

2Loss of energy

If heat sources operate independently without coordination, then each heat source can be controlled separately, but energy consumption increases due to lack of optimization across multiple heat sources

Engineering Contradiction:
Improveenergy consumptionVSAvoidheat source coordination automation
Core Design Contradiction:
Loss of energyVSExtent of automation

Solution Approach 1:

The patent implements a feedback mechanism where the controller continuously receives information about heat supply capacity and demand from multiple heat sources and grids, processes this information, and adjusts heat distribution accordingly. This closed-loop control system optimizes energy consumption by dynamically responding to changing supply and demand conditions across the heating and electricity grids.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts the operation of multiple heat sources based on real-time conditions. The controller can switch between different heat sources, adjust their output levels, and coordinate their operation to match actual demand patterns, transforming static independent heat source operation into dynamic coordinated control that minimizes energy waste.

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If energy distribution does not account for temporal variations in supply and demand, then system operation is simplified, but environmental impact worsens due to suboptimal energy utilization

Engineering Contradiction:
Improveenvironmental impactVSAvoidtemporal energy management complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent incorporates temporal planning by predicting future heat supply capacity and demand patterns, and electricity grid conditions. The controller uses this predictive information to pre-optimize heat source coordination and distribution strategies, allowing the system to prepare for upcoming supply-demand imbalances and reduce environmental impact before they occur rather than reacting after the fact.

Inventive Principle:
