Mechanical Urinal Flusher Using User Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public urinals often remain unflushed due to manual operation, leading to unsanitary conditions and water wastage, and high-tech automatic systems are expensive and prone to maintenance issues, necessitating a low-cost, automatic flushing solution that conserves water and reduces human contact with potentially germ-infested surfaces.
Innovation Solution
A dual-valve pipe mechanism actuated by a spring-loaded mechanical compressible platform, which automatically flushes a specified quantity of water into the urinal without direct human contact, using the weight of the user to operate the valves and maintain a temporary water reservoir for efficient flushing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual flushing systems are used, then device complexity is reduced, but reliability of flushing operation deteriorates due to user negligence
Solution Approach 1:
The system uses the user's own weight on the seat as the actuating force to automatically trigger the flush mechanism, making the system self-operating without requiring manual intervention or external power sources. The mechanical platform compresses under user weight, activating the valve system through pure mechanical means.
Solution Approach 2:
The invention replaces electronic sensing systems with a purely mechanical weight-detection platform that converts user weight directly into mechanical motion to operate the flush valve. This mechanical substitution eliminates complex electronics while maintaining automatic operation.
2Reliability
If high-tech automatic flushing systems are used, then reliability of automatic flushing is improved, but manufacturing cost and maintenance cost increase
Solution Approach 1:
The system employs simple, inexpensive mechanical components that can be easily manufactured and replaced if needed. The mechanical platform, springs, and valve assemblies are basic components with long service lives and low manufacturing costs compared to electronic sensors and control systems.
Solution Approach 2:
By replacing expensive electronic sensors, microprocessors, and power systems with a simple mechanical weight-detection and actuation system, the invention dramatically reduces manufacturing and maintenance costs while maintaining reliable automatic operation.
3Device complexity
If manual flushing is used, then device complexity is reduced, but water wastage increases due to improper flushing
Solution Approach 1:
The system provides automatic feedback through the mechanical connection between the weight platform and the valve actuation mechanism. When weight is detected, the system automatically triggers the flush sequence, ensuring proper flushing occurs without user intervention or forgetfulness.
Solution Approach 2:
The system monitors and responds to user presence automatically through mechanical weight detection, self-regulating the flush operation based on actual usage conditions without requiring manual control or external monitoring.
4Device complexity
If manual flush handles are used, then device complexity is reduced, but hygiene conditions deteriorate due to hand contact with germs
Solution Approach 1:
The mechanical platform acts as an intermediary between the user and the flush actuation mechanism. Users interact only with the seat platform, which transfers weight through mechanical linkages to operate the valves, eliminating direct hand contact with flush handles or buttons.
Solution Approach 2:
The system automatically performs the flush actuation function that would otherwise require manual hand operation, using the user's own weight as the triggering mechanism. This eliminates the need for hand-contact interfaces entirely.
