Requirements: Design several concept proposals for both vehicle and home air quality monitors. Please refer to the attachment for detailed specifications. Target User Group: People who have recently renovated their homes, health-conscious individuals. Scenario Analysis Applicable Environments: Two products — one for vehicle use and one for home use. The vehicle-mounted version requires a threaded mounting mechanism for installation. Sales Channels: E-commerce platforms or offline retail stores. Target Region: No restrictions. Product Specifications Design Direction One: Product Name: Vehicle Environment Monitor Product Functions: Temperature and humidity detection Formaldehyde detection and removal Carbon dioxide (CO2) detection Product Description: Used to monitor air quality inside the vehicle. The product contains built-in formaldehyde removal particles that can volatilize and eliminate formaldehyde inside the car. Hardware Components: Temperature and humidity sensor, formaldehyde module, CO2 module, screen (optional). For vehicle mounting, a threaded installation mechanism is required (please refer to the diagram below for thread specifications — the screw can be unscrewed; this interface is used for both power supply and fixation). Product Grade: Mid-to-high end Design Direction Two: Product Name: Home Environment Monitor Product Functions: Temperature and humidity detection PM2.5 detection Formaldehyde detection and removal VOC (Volatile Organic Compounds) detection Carbon dioxide (CO2) detection Light intensity detection Alarm clock function Product Description: Used to monitor indoor air quality in the home. Functions similarly to an ultrasonic humidifier, featuring a mist spray function to eliminate formaldehyde. Hardware Components: Temperature and humidity sensor, PM2.5 sensor, formaldehyde module, CO2 module, light intensity sensor, 5000mAh battery.
