Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current toilet designs require special handling techniques for safe waste management, often relying on water, chemicals, or biological processes that can be environmentally harmful and inefficient, particularly in water-scarce locations or remote settings.
Innovation Solution
A toilet apparatus with a waste material receiving bowl and sensor system that uses an absorbent media with an indicator, allowing for detection of the media's presence and quantity, triggering specific actions to enhance waste management through agitation and dehydration, minimizing odors and sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water-based flush toilets are used, then waste removal is effective, but excessive water consumption occurs
Solution Approach 1:
The patent extracts the water from the waste removal system and replaces it with an absorbent formulation that chemically binds to waste. The formulation is applied directly to waste in the bowl, absorbing moisture and binding waste particles without requiring water for flushing.
Solution Approach 2:
The patent changes the physical and chemical parameters of the waste management system by using a formulation with specific pH levels, absorbency characteristics, and binding properties. The formulation's parameters are optimized to effectively manage waste without water.
2Quantity of substance
If chemical-based toilets are used, then water usage is reduced, but harmful chemicals are released into the environment
Solution Approach 1:
The patent uses a formulation with controlled chemical parameters including pH balance, absorbency rate, and binding strength. The chemical composition is designed to be environmentally benign while maintaining effective waste management properties.
Solution Approach 2:
The patent employs a composite formulation combining multiple components including absorbent materials, binding agents, and pH-adjusting substances. This composite approach creates a synergistic effect that manages waste effectively while minimizing environmental harm.
3Quantity of substance
If composting toilets are used, then water consumption is minimized, but special handling and ventilation requirements increase system complexity
Solution Approach 1:
The patent extracts the complex ventilation and handling systems from the toilet and replaces them with a simple absorbent formulation application system. The formulation is applied directly to waste in the bowl, eliminating the need for complex composting infrastructure.
Solution Approach 2:
The patent employs disposable absorbent formulations that are applied to waste and then disposed of with the waste. This eliminates the need for maintaining complex composting systems, ventilation infrastructure, and specialized handling equipment.
4Loss of information
If absorbent media with indicator is used, then waste monitoring capability is improved, but device complexity increases due to sensor system
Solution Approach 1:
The patent incorporates color-changing indicators into the absorbent formulation that visually signal waste levels and conditions. This simple optical indicator system provides monitoring capability without requiring complex sensors or electronics.
Solution Approach 2:
The patent replaces complex mechanical or electronic sensor systems with a simple visual indicator system based on color changes. This substitution provides adequate monitoring capability while dramatically reducing system complexity.

AI summary
A toilet apparatus has a waste material receiving bowl with an opening to receive an absorbent media and indicator and a sensor to detect a presence of the indicator in the material receiving bowl when the indicator is present in the material receiving bowl and transmit a signal indicating the indicator is present in the material receiving bowl. A control circuit receives the signal from the sensor, processes the signal to determine the indicator is present in the material receiving bowl, and causes one or more actions to be taken by the toilet apparatus based on determining the indicator is present in the material receiving bowl.
