Solution Overview
Problem
The existing non-water lavatory flushing devices are overly complex, prone to misjudging stool and urine, and can be damaged by hard objects, leading to inefficient flushing and potential waste of flushing liquid.
Innovation Solution
A simplified lavatory pan device with a stool and urine tray, supported by a moment force producing device, which uses gravity, electromagnetic, or mechanical structures to differentiate between stool and urine, eliminating the need for a crushing and centrifugal device and improving flushing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a crushing and centrifugal device is used to process stool and urine, then the flushing liquid can be separated and collected, but the structure becomes complicated and the device is vulnerable to damage from hard objects
Solution Approach 1:
The patent removes the crushing and centrifugal device from the system entirely. Instead of processing waste through mechanical crushing and centrifugal separation, the invention directly collects urine and stool through separate channels into各自的收集箱，eliminating the complex and vulnerable mechanical processing components while maintaining the core function of waste separation and collection
Solution Approach 2:
The patent segments the waste collection system into separate pathways for urine and stool from the beginning, with dedicated collection boxes for each type of waste. This segmentation eliminates the need for a single processing unit that would require crushing and centrifugal separation, thereby removing the complex mechanical device while maintaining effective waste separation
2Extent of automation
If software is used to identify stool or urine by calculating time, then automatic control is achieved, but misjudgment occurs and flushing liquid is wasted
Solution Approach 1:
The patent physically segments the collection system into separate channels and boxes for urine and stool, eliminating reliance on software time-calculation for identification. The physical separation ensures accurate routing of waste materials without misjudgment, while maintaining automatic control through sensor-based detection that triggers appropriate collection processes
Solution Approach 2:
The patent replaces the software-based time calculation method with a physical separation system enhanced by sensor detection. Instead of using computational algorithms to identify waste type, the system uses dedicated collection channels and sensors to accurately distinguish and route urine and stool, eliminating misidentification and waste of flushing liquid
3Ease of operation
If a four-way valve and multiple electric control valves are used to control flow directions, then waste routing is achieved, but the structure becomes complicated and cost increases
Solution Approach 1:
The patent removes the complex four-way valve and multiple electric control valves from the system. Instead of using a centralized valve system to control flow directions, the invention employs separate dedicated collection channels and boxes for urine and stool, eliminating the need for complex flow control mechanisms while maintaining effective waste routing capability
Solution Approach 2:
The patent segments the flow control system into separate dedicated pathways for urine and stool collection. Each waste type has its own collection channel and box, eliminating the need for a complex centralized valve system. This segmentation achieves effective waste routing through simple, direct pathways rather than complex flow control mechanisms

AI summary
A lavatory pan device for separating stool and urine includes a stool and urine tray, a supporting device, and a moment force producing device. The stool and urine tray consists of a flat plate and the rib inclining upward and extending outward from the whole or partial edge of the flat plate. The lavatory pan has an opening or an entry way at the longitudinal side and is connected on the supporting device. Through the moment force produced by the prescribed moment force producing device, the stool and urine tray can roll over on the supporting device. The described moment force producing device is set on the stool and urine tray and it is between tow supports of the above supporting device and the opening or entry way.
