Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional masks or basic face shields are used, then protection against viral transmission is provided, but the effectiveness is limited and resources are scarce
Solution Approach 1:
The patent applies parameter changes by modifying the physical-chemical properties of the face shield surface through electrostatic charging. The conductive plate generates an electrostatic field that creates attractive forces on contaminated droplets and aerosols, changing the interaction parameters between the shield surface and airborne particles. This transforms a passive physical barrier into an active electrostatic attraction system, enhancing protection effectiveness without fundamentally redesigning the overall shield structure.
Solution Approach 2:
The invention employs composite materials by integrating a conductive plate (electrostatic component) with the traditional face shield structure (physical barrier component). This composite system combines the protective function of the physical barrier with the active contamination capture function of the electrostatic field, creating a multi-functional protection device that addresses both structural integrity and enhanced viral transmission prevention.
2Reliability
If electrostatic attraction system is added to face shield, then retention of contaminated droplets and aerosols is improved, but device complexity increases
Solution Approach 1:
The patent applies the taking out principle by extracting the electrostatic generation function into a separate, removable conductive plate that can be independently charged and replaced. This modular approach allows the electrostatic system to be added to the face shield without permanently integrating complex electronic charging circuits into the main shield structure. The conductive plate serves as a standalone electrostatic component that simplifies the overall device complexity while maintaining droplet retention effectiveness.
Solution Approach 2:
The invention implements self-service through the electrostatic field's automatic attraction and retention of contaminated droplets and aerosols without requiring active control systems. Once the conductive plate is charged, the electrostatic attraction operates passively and continuously, automatically capturing particles based on their electrical properties. This eliminates the need for complex real-time control electronics, motion sensors, or power management systems during operation, reducing device complexity while maintaining reliable droplet retention.
3Loss of information
If monitoring system is implemented, then usage and sanitation tracking is enhanced, but device complexity and cost increase
Solution Approach 1:
The patent applies the intermediary principle by introducing motion sensors and electronic modules as mediators between the physical face shield and the monitoring system. These sensors detect touch contacts and usage conditions, converting physical interactions into electrical signals that can be transmitted and stored. This intermediary layer enables comprehensive usage tracking without requiring the face shield itself to become complex, as the monitoring function is handled by separate detectable components that bridge the physical and digital domains.
