Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional steam or hot water powered lithium bromide absorption refrigeration units are used, then the system can provide cooling function, but it causes environmental pollution and does not align with carbon-neutral strategy
Solution Approach 1:
The patent replaces traditional mechanical/thermal heating systems (steam boilers, hot water systems) with an electric heating system. The electric heating device uses electrical energy directly to heat the lithium bromide solution, eliminating the need for combustion-based steam generation and hot water heating, thereby reducing environmental pollution and aligning with carbon-neutral goals.
Solution Approach 2:
The patent changes the energy source parameter from thermal/chemical energy (steam, hot water) to electrical energy. This parameter change enables the system to operate without combustion processes, reducing harmful emissions while maintaining the absorption refrigeration function.
2Ease of operation
If direct-fired non-electric lithium bromide absorption refrigeration units are used, then the system can operate independently, but it increases greenhouse gas emissions and pollution
Solution Approach 1:
The patent replaces the direct-fired combustion system with an electric heating system. The electric heating device provides the necessary thermal energy for the absorption cycle without requiring fuel combustion, thereby maintaining independent operation capability while eliminating greenhouse gas emissions and pollution associated with direct-fired systems.
3Object-affected harmful factors
If electric heating is used to power the lithium bromide absorption system, then environmental impact is reduced, but energy consumption from grid increases
Solution Approach 1:
The patent incorporates a heat storage device that pre-stores thermal energy during periods when electricity is available or cheaper. The heat storage device accumulates heat in advance, allowing the absorption refrigeration system to operate using stored heat rather than requiring continuous grid electricity, thereby reducing peak energy consumption and optimizing grid energy usage.
Solution Approach 2:
The patent introduces a heat storage device as an intermediary between the electric heating system and the absorption refrigeration cycle. This intermediary stores thermal energy and releases it when needed, decoupling the timing of energy consumption from energy usage, and reducing the immediate burden on grid energy consumption while maintaining environmental benefits.
4Use of energy by moving object
If an electric heat generator with energy storage device is implemented, then energy efficiency is improved, but system complexity increases
Solution Approach 1:
The patent merges the electric heating device and the heat storage device into an integrated electric heat generator system. By combining these functions into a single coordinated system, the patent improves energy efficiency through heat storage while managing system complexity through integrated design, where the heating and storage components work together as a unified unit rather than separate systems.
