Fluid Dispensing Device Emergency Alert Sensor System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single-dose or two-dose fluid product dispensing devices do not effectively address the need for emergency alerts when a user attempts to actuate the device but is unable to do so, and they are often complex and costly to manufacture.
Innovation Solution
A fluid product dispensing device with an electronic module featuring a wireless communication module, GPS, and sensor system that automatically detects attempts to use the device and initiates an emergency call when simultaneous activation of sensors on the dispensing head and body is detected, using sensors like microcurrent, capacitive, or infrared sensors, and a power source to minimize energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor system with wireless communication module is added to detect attempted use and trigger emergency alerts, then user safety and emergency response capability are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The device is divided into functional modules: sensor system (with first sensor on dispensing head and second sensor on body), wireless communication module (GSM/WiFi/Bluetooth), GPS module, and power source. Each module performs a specific function, allowing independent optimization and simplifying manufacturing while maintaining overall system reliability for emergency detection and alerting
Solution Approach 2:
The wireless communication module is designed to support multiple communication protocols (GSM, WiFi, Bluetooth) and can perform multiple functions including emergency calls, location tracking via GPS, and data transmission. This multi-functionality consolidates what could be multiple separate systems into one integrated module, reducing overall device complexity while enhancing emergency response capabilities
2Duration of action of stationary object
If the electronic module is kept in standby mode with zero or minimal energy consumption, then battery life is extended, but the device cannot immediately detect and respond to attempted use
Solution Approach 1:
The electronic module operates in periodic cycles, remaining in low-power standby mode most of the time and activating only when sensors detect attempted use. This periodic operation pattern allows the device to conserve battery energy while still providing timely emergency alerts when needed, as the sensor system continuously monitors for activation attempts
Solution Approach 2:
Traditional mechanical switches or continuous power systems are replaced with sensor-based detection (micro current, capacitive, infrared, light, audio, temperature, or humidity sensors) that can trigger electronic activation. This substitution allows for more efficient power management by eliminating the need for continuous mechanical engagement while maintaining rapid response capability through electronic sensing
3Measurement precision
If multiple sensor types (micro current, capacitive, infrared, light, audio, temperature, humidity) are integrated into the sensor system, then detection accuracy for attempted use is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
Different sensor types are strategically placed at specific locations: the first sensor is disposed on the dispensing head and the second sensor on the body. Each sensor type is selected based on the local detection requirements at its position, allowing for optimized detection accuracy without requiring all sensor types throughout the entire device. This localized approach reduces manufacturing complexity while maintaining high detection precision
