Gravity Sanitary Riser Layout for Construction Waste Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sanitary waste removal systems require extensive labor and use of vertical access devices like elevators or cranes, which are inefficient and expose workers to health risks.
Innovation Solution
A gravity-based sanitary waste removal system that allows direct evacuation of waste from multi-floor buildings without the need for vertical access devices, using a tankless toilet connected to a sanitary riser stack and water supply riser, which can be easily adjusted and reused across construction sites.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile temporary toilets are used for sanitary waste removal, then waste can be collected, but extensive labor and vertical access devices are required for removal and pumping
Solution Approach 1:
The patent replaces the mechanical system of physically moving toilets with a gravity-based fluid transport system. Waste is evacuated directly through gravity flow through the riser stack, eliminating the need for mechanical removal of toilet assemblies using cranes or elevators.
Solution Approach 2:
The patent extracts the waste evacuation function from the toilet assembly itself, allowing the toilet to remain in place while waste is separately removed through the riser stack system. This separates the collection function from the removal function.
2Productivity
If mobile temporary toilets are used, then waste can be collected, but time and costs increase due to frequent removal and replacement
Solution Approach 1:
The gravity-based system replaces time-consuming mechanical removal and replacement operations with continuous gravity-driven waste evacuation, significantly reducing servicing time and improving overall productivity.
3Object-affected harmful factors
If mobile temporary toilets are used, then waste can be collected, but worker exposure to sanitary waste increases health risks
Solution Approach 1:
The patent extracts waste directly from the building through the riser stack, eliminating the need for workers to physically handle or move contaminated toilet assemblies. This reduces exposure to harmful factors while maintaining safe operational procedures.
4Ease of operation
If vertical access devices like elevators or cranes are used, then toilet assemblies can be removed, but construction/production activities are disrupted
Solution Approach 1:
The patent replaces the need for vertical access devices with a gravity-based waste evacuation system that operates independently, allowing construction activities to continue uninterrupted while waste is continuously removed through the riser stack.
