Cooling Sensing Composition for Fluid Overflow Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions fail to effectively alert individuals of fluid overflow from the body, particularly in situations like hemorrhage or menstrual cycles, where timely detection is crucial but often delayed due to immersion in activities or unpredictable onset.
Innovation Solution
A sensory stimulant composition that provides a cooling sensation upon exposure to bodily fluids, comprising urea, ammonium nitrate, and casein, which absorbs heat to induce a significant temperature drop, usable in various forms like band-aids, pads, and tampons, to alert users of fluid overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If daily use panty liners are used to prevent menstrual blood leakage, then blood leakage is controlled for a few minutes after cycle starts, but the thin liner cannot hold the gush of blood and leaking is bound to take place
Solution Approach 1:
The patent utilizes the phase transition of urea from solid to liquid, which absorbs heat and creates a cooling sensation. This phase change occurs when bodily fluids contact the composition, providing both detection and alerting functions without requiring thicker liner materials
Solution Approach 2:
The patent combines urea, ammonium nitrate, and casein to create a composite material that provides multiple functions: urea and ammonium nitrate provide the cooling sensation through phase transition, while casein provides structural support and absorption capabilities, enabling effective blood containment without increasing overall liner thickness
2Measurement precision
If women rely on the feeling of vaginal excretions to detect menstrual cycle start, then they can sense increased mucous production, but the sensation is equivalent to menstrual cycle starting and causes numerous false alarms
Solution Approach 1:
The patent incorporates color indicators that change when contacted by bodily fluids, providing a clear visual signal that distinguishes actual menstrual flow from normal vaginal excretions. This visual feedback mechanism eliminates the ambiguity of tactile sensations and reduces false alarms
Solution Approach 2:
The phase transition of urea from solid to liquid provides a distinct cooling sensation that occurs only when sufficient fluid contact is made, creating a reliable detection signal that differentiates menstrual cycle onset from normal vaginal secretions
3Ease of operation
If patients are engaged in entertainment shows, gaming or training, then they are fully immersed in the activity, but they would not be aware of the surroundings and bleeding detection is delayed
Solution Approach 1:
The patent replaces the need for conscious mechanical detection (feeling or visual inspection) with an automatic sensory response system. The cooling sensation and color change occur automatically upon fluid contact, providing passive detection that does not require the user's attention or awareness
Solution Approach 2:
The composition performs self-detection and self-signal generation functions. When bodily fluids contact the urea-ammonium nitrate-casein composition, it automatically undergoes phase transition and produces cooling sensation and color changes, eliminating the need for active monitoring by the user
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively indicates fluid overflow by providing a noticeable cooling effect, achieving a temperature drop of up to 30°C, ensuring timely awareness of fluid leakage or bleeding, even in unaware individuals.
Implementation Method 1
The composition on exposure to fluid such as but not limited to: water, blood, perspiration, urine, etc., starts to dissolve by absorption of heat from the environment and undergoes phase change to provide a significant cooling sensation
Implementation Method 2
The composition on exposure to fluid such as but not limited to: water, blood, perspiration, urine, etc., starts to dissolve by absorption of heat from the environment and undergoes phase change to provide a significant cooling sensation
