Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caregivers often struggle to determine when to change diapers, leading to potential skin problems due to irregular changes, especially with infants, as existing diapers do not provide clear indicators of when they need to be replaced.
Innovation Solution
A diaper prediction and correction system comprising a diaper sensor, a server, and a mobile device that uses crowdsourced data to determine if a diaper needs to be replaced based on environmental parameters like temperature and humidity, and user feedback to adjust criteria for personalized alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a diaper uses a very strong polymer as an absorber to increase absorption capacity, then the diaper can absorb up to 50 times its own weight of water, but the dependent (e.g., parents of infants) are often unsure when the infants need to change diapers after urination
Solution Approach 1:
The patent employs color-changing indicators or visual cues in the diaper system to communicate absorption status and timing information to caregivers. This allows the diaper to maintain high polymer absorption capacity while providing clear visual feedback about when the diaper needs to be changed, resolving the information loss problem.
Solution Approach 2:
The patent implements feedback mechanisms such as sensors, mobile applications, or other communication systems that provide real-time or near-real-time information to caregivers about the diaper's absorption status and optimal change timing. This feedback loop maintains the high absorption capacity of the polymer while eliminating the uncertainty about when to change the diaper.
2Quantity of substance
If the diaper uses strong polymer absorber to increase water absorption, then the diaper can hold more urine, but failure to change the diaper on a sufficiently regular basis can result in skin problems
Solution Approach 1:
The patent uses feedback systems including sensors, mobile notifications, or visual indicators that inform caregivers when the diaper reaches optimal change timing. This ensures that even though the diaper can hold large amounts of urine through strong polymer absorption, the feedback mechanism prompts timely changes before skin problems occur, balancing absorption capacity with skin health.
Solution Approach 2:
The patent implements preliminary action by providing advance notice or early warnings to caregivers before the diaper reaches a critical state that would cause skin problems. This allows caregivers to change the diaper proactively rather than reactively, maintaining the benefits of high absorption capacity while preventing harmful skin effects.
3Measurement precision
If the system uses crowdsourcing data and environmental parameters to create customized predictive models, then the accuracy of diaper change prediction is improved, but the device complexity increases
Solution Approach 1:
The patent leverages the universality of mobile devices and existing sensor technologies to implement complex predictive modeling without proportionally increasing device complexity. By using a smartphone or tablet as the central processing unit, the system can incorporate crowdsourcing data, environmental parameters, and machine learning algorithms while keeping the actual diaper hardware relatively simple and multi-functional.
Solution Approach 2:
The patent introduces an intermediary layer (mobile application, cloud platform, or processing unit) that handles the complexity of data collection, environmental parameter integration, and predictive modeling. This intermediary manages the computational complexity away from the diaper sensor itself, allowing high prediction accuracy while keeping the wearable component simple and comfortable for the infant.
