Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage containers do not adequately monitor the temperature of liquids and prevent flow when the temperature is outside a safe range for individuals sensitive to heat and cold, such as burn patients.
Innovation Solution
A safety lid with embedded microcomponents that measure liquid temperature and control a fluid passageway to restrict flow if the temperature is outside a set range, providing both visual and audio alerts to ensure safe consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing beverage containers are used, then the device is simple and low cost, but the temperature monitoring and flow restriction functions are missing
Solution Approach 1:
The patent combines multiple functions (temperature monitoring, alert notification, and flow restriction) into a single integrated safety lid assembly. The microcontroller, temperature sensor, alert components, and valve mechanism are merged into one unit that attaches to the beverage container, eliminating the need for separate monitoring and control devices.
Solution Approach 2:
The safety lid employs a nested structure where the microcomponents (temperature sensor, microcontroller, alert components) are embedded within the lid body, and the valve mechanism is integrated within the fluid passageway structure. This nesting approach allows complex functionality to be contained within a compact form factor.
2Object-affected harmful factors
If existing beverage containers are used, then the device structure is simple, but the mechanism for preventing beverage flow at unsafe temperatures is missing
Solution Approach 1:
The safety lid implements preliminary anti-action by proactively preventing harmful beverage flow before it can reach the user. The temperature sensor continuously monitors the beverage, and the valve is positioned to block the fluid passageway in advance when unsafe temperatures are detected, stopping the harmful flow before it causes injury.
Solution Approach 2:
The safety lid acts as an intermediary device between the beverage container and the user. It introduces a valve mechanism that mediates the flow of beverage, allowing safe flow when temperature is appropriate and blocking flow when temperature is unsafe, thereby protecting the user from harmful temperatures.
3Object-affected harmful factors
If temperature monitoring and flow restriction are added, then safety for sensitive individuals is improved, but the device complexity and cost increase
Solution Approach 1:
The safety lid is designed as a universal device that can be attached to various beverage container types. It performs multiple functions simultaneously: temperature monitoring via sensor, user notification via alert components, and flow control via valve mechanism, making it applicable to different container designs without requiring container-specific modifications.
Solution Approach 2:
The safety lid employs self-service through automatic temperature monitoring and autonomous flow restriction. The microcontroller continuously reads temperature data from the sensor and automatically actuates the valve when unsafe conditions are detected, eliminating the need for user intervention or manual temperature checking.
