Solution Overview
Problem
Current methods for eliminating algae and microorganisms in water bodies rely on chemical additives that leave residues, and existing ultrasound devices face limitations due to moisture issues and limited range, affecting their effectiveness.
Innovation Solution
An ultrasonic wave antenna designed with enamelled copper wire, a hollow PVC tube, and a ferrite or iron bar, capable of generating a sine-wave with consistent positive and negative peaks across a 4500-meter range, using a frequency of 50 to 90 kHz, which is more durable and resistant to moisture, allowing for effective algae elimination without chemical residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chemical additives are used to eliminate algae and microorganisms, then effective elimination is achieved, but chemical residues remain in the water
Solution Approach 1:
The patent replaces chemical elimination methods with a mechanical/physical ultrasound-based system. The antenna generates ultrasonic waves that mechanically disrupt algae and microorganisms through cavitation and vibration, eliminating the need for chemical additives and their associated residues.
Solution Approach 2:
The invention changes the operating parameters of ultrasound devices by using a resonant frequency antenna design that operates at specific frequencies (20-100 kHz) to maximize cavitation effects on algae while minimizing impact on aquatic life. The antenna's dimensional parameters are specifically calculated to achieve full wave amplitude generation.
2Productivity
If existing ultrasound devices are used, then algae elimination is achieved, but moisture issues and limited range reduce effectiveness
Solution Approach 1:
The patent employs a hollow PVC cylindrical tube as a protective shell for the antenna elements. This flexible yet durable enclosure protects the internal components from moisture and condensation while allowing ultrasonic waves to propagate effectively through the water environment.
Solution Approach 2:
The antenna uses composite construction combining enamelled copper wire (conductive element), ferrite or iron bar (magnetic core), and PVC tube (protective housing). This composite structure provides both the necessary electromagnetic properties for ultrasound generation and protection against moisture, extending operational reliability and range.
3Power
If full wave amplitude is generated with positive and negative peaks, then ultrasound effectiveness is maximized, but device complexity increases
Solution Approach 1:
The antenna is designed to generate periodic ultrasonic waves with equal positive and negative peaks at frequencies between 20-100 kHz. This periodic oscillation creates consistent cavitation patterns in the water, maximizing the mechanical disruption of algae while maintaining a relatively simple continuous operation mode.
Solution Approach 2:
The invention directly generates mechanical vibrations through the ultrasonic antenna elements that propagate through the water medium. The vibration mechanism is simplified by using resonant frequency operation, where the antenna structure itself vibrates at its natural frequency to produce full-amplitude waves without requiring complex amplification systems.
