Engineering Contradiction Analysis
1Object-affected harmful factors
If ion exchange resin softeners are used to reduce water hardness, then water hardness is reduced, but energy consumption increases and maintenance requirements increase
Solution Approach 1:
The patent replaces the mechanical ion exchange resin softening system with an acoustic field-based treatment system. Ultrasonic waves and electromagnetic fields are used to alter the crystalline structure of calcium carbonate precipitates, preventing limescale formation without requiring mechanical resin beds, electrical heating elements, or chemical regeneration processes.
Solution Approach 2:
The patent changes the physical-chemical parameters of water by applying acoustic and electromagnetic fields that modify the crystallization behavior of calcium carbonate. The ultrasonic frequency and electromagnetic field strength are adjusted to transform hard water into soft water equivalent without actual ion exchange, thereby reducing hardness effects without the energy costs of traditional systems.
2Object-affected harmful factors
If ion exchange resin softeners are used to reduce water hardness, then water hardness is reduced, but maintenance requirements increase
Solution Approach 1:
The acoustic and electromagnetic field treatment system operates autonomously without requiring manual intervention for resin replacement, salt refilling, or filter cleaning. The system self-regulates the treatment process based on water flow detection, eliminating the periodic maintenance tasks associated with ion exchange softeners while continuously preventing limescale formation.
Solution Approach 2:
The patent extracts the maintenance-intensive ion exchange resin component from the water softening process and replaces it with a field-based treatment method. By removing the physical resin medium that requires regeneration and replacement, the system eliminates the associated maintenance burden while achieving the same water softening effect through acoustic and electromagnetic field application.
3Extent of automation
If solenoid valves and PLCs are used for gas injection control, then gas delivery can be automated, but device complexity and electronic components increase
Solution Approach 1:
The patent replaces solenoid valves and PLC-based electronic control systems with a purely mechanical flow detection and control mechanism. A flow detector senses water flow and mechanically actuates a valve to release gas bubbles, eliminating complex electronic circuits, programmable logic controllers, and electromagnetic components while maintaining automated gas delivery functionality.
Solution Approach 2:
The patent introduces a flow detector as an intermediary device that bridges water flow sensing and gas valve actuation without requiring direct electronic control. The detector mechanically translates water flow presence into valve opening/closing actions, serving as a simple intermediary that achieves automation through mechanical means rather than complex electronic systems.
