Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing energy storage technologies are used to store renewable energy, then energy can be stored for later use, but the systems suffer from high costs, inefficiencies, and high infrastructure requirements

Engineering Contradiction:

Solution Approach 1:

The patent extracts the core energy storage function from complex existing systems (batteries, pumped hydro, traditional CAES) and implements it using a simplified compressed air storage system with above-ground tanks, eliminating the need for complex infrastructure while maintaining storage reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces traditional mechanical energy storage mechanisms (moving parts in batteries, water movement in pumped hydro, mechanical compressors in traditional CAES) with a static compressed air storage system that uses pressure vessels and control valves, reducing mechanical complexity while maintaining functionality

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

2Productivity

If renewable energy is produced during low-demand periods, then green energy generation increases, but the energy must be curtailed due to supply-demand imbalance

AI summary

Disclosed is a machine learning energy management system that regulates incoming energy sources into compressed air storage operations and energy generation. Compressed air is directed into a thermoregulation system that cycles storage tanks according to physical qualities. A boost impulse creates energy to initiate the electrical energy generation. The compressed air operations and energy generation leverage the heating and cooling of an external HVAC system to improve performance and conservation of the heating and cooling for an external building, wherein compressed air is used to drive a coolant compressor. The system combines real-time data, historical performance data, algorithm control, variable air pressure for demand-based generation, tank-to-tank thermal cycling, building air heat exchanger, and boost pulsation to achieve optimized system efficiency and responsiveness.
