Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plant-based systems are used to generate negative air ions, then health benefits are provided, but air cleaning efficiency and coverage area are limited
Solution Approach 1:
The patent combines multiple plants into a single integrated air purification system, where plants are electrically connected in series or parallel configurations. This merging approach allows the system to achieve both the health benefits of plant-based negative ion generation and improved air cleaning efficiency through cumulative effect across multiple plants working together.
Solution Approach 2:
The system serves multiple functions simultaneously: it generates negative air ions for health benefits, captures particulate matter through precipitation, and provides air purification. By making the system multi-functional, it addresses both the health benefit requirement and the air cleaning efficiency requirement within a single integrated solution.
2Reliability
If plant-based systems are used to generate negative air ions, then health benefits are provided, but coverage area is limited
Solution Approach 1:
By connecting multiple plants electrically in series or parallel, the system extends the coverage area while maintaining the health benefits. The electrical connection allows voltage pulses to stimulate multiple plants simultaneously, creating a larger effective coverage area compared to a single plant system.
Solution Approach 2:
The patent transitions from a single-point source (one plant) to a distributed network of multiple plants connected electrically. This dimensional expansion allows the system to cover a larger spatial area while maintaining the beneficial effects at each plant location, effectively solving the coverage area limitation.
3Productivity
If voltage pulse is applied to stimulate plants, then negative air ion generation is improved, but safety issues arise due to unstable load condition
Solution Approach 1:
The system incorporates feedback mechanisms through the electrical connection between plants, allowing the circuit to self-regulate based on load conditions. The series or parallel configuration provides natural feedback that stabilizes voltage and current distribution, preventing unsafe conditions while maintaining effective negative ion generation.
Solution Approach 2:
The electrical circuit design with multiple plants connected in series or parallel provides built-in protection against unstable load conditions. The configuration acts as a cushioning mechanism that prevents voltage spikes or current surges from causing safety issues, while still allowing effective stimulation of plants for negative ion generation.
4Object-affected harmful factors
If air filters are used to trap airborne particles, then particulate matter is captured, but frequent filter changes are required
Solution Approach 1:
The patent replaces the mechanical filtration system (physical filters that require frequent replacement) with an electrostatic precipitation system using voltage-pulsed plants. This substitution eliminates the need for frequent filter changes while maintaining effective particulate matter capture through negative ion precipitation.
Solution Approach 2:
The system changes the fundamental mechanism from physical filtration to electrostatic precipitation. By altering the parameter from mechanical trapping to electrical field-based particle capture, the system achieves continuous operation without the maintenance burden of frequent filter replacements.
5Object-affected harmful factors
If air filters are used to capture particulate matter, then air purification is achieved, but upfront deployment cost is significant
Solution Approach 1:
The system replaces expensive, complex filtration systems with a simpler, more cost-effective plant-based electrostatic precipitation system. By using naturally occurring plants stimulated by voltage pulses, the upfront deployment cost is significantly reduced while maintaining effective particulate matter capture capability.
Solution Approach 2:
The system uses living plants that naturally generate negative ions when stimulated, eliminating the need for expensive artificial filtration materials. The plants perform the purification function themselves through their natural physiological response to voltage pulses, reducing overall system cost.
