Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional toilets require a bulky water tank due to insufficient water flow from typical household pipes, making them inefficient and space-consuming, as they struggle to effectively flush the water trap without a tank.
Innovation Solution
A toilet design featuring a conical water trap with a narrow inlet and a wider outlet, utilizing tangentially generated water jets to create a vortex that efficiently moves particles from the inlet to the outlet, reducing the need for a water tank by using the household water supply directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a water tank is used to store flush water, then sufficient water flow for flushing is achieved, but the toilet becomes bulky and space-consuming
Solution Approach 1:
The patent changes the geometric parameters of the water trap by implementing a conical shape with increasing diameter from inlet to outlet. This parameter change optimizes the flow dynamics, allowing efficient flushing with lower water quantities, thereby eliminating the need for a large water tank and reducing overall toilet volume.
Solution Approach 2:
The patent applies curved surfaces by designing the water trap as a conical structure with smooth curved transitions. This curvature optimizes water flow patterns, creates effective vortex motion, and improves particle transport efficiency, enabling tankless operation with reduced water consumption.
2Productivity
If traditional water trap design is used, then结构简单 is maintained, but efficient emptying of particles cannot be achieved with low water flow
Solution Approach 1:
The patent implements parameter changes by transitioning from a traditional cylindrical water trap to a conical design with increasing diameter. This geometric parameter change enhances the vortex effect and centrifugal forces, significantly improving particle separation and transport efficiency with reduced water flow quantities.
Solution Approach 2:
The patent utilizes hydraulic principles by designing the conical water trap to optimize water flow dynamics. The increasing diameter creates controlled vortex flow and centrifugal forces that efficiently separate and transport particles, achieving high flushing efficiency with minimal water consumption.
3Productivity
If the conical part has increasing diameter towards outlet, then particle emptying efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by defining the conical shape with specific diameter variations along the length. This geometric optimization improves particle emptying efficiency while maintaining manufacturability through standard conical forming processes, balancing performance enhancement with manufacturing feasibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for effective flushing with reduced water flow, minimizing material usage, space requirements, and maintenance, while ensuring efficient emptying of the water trap, even at typical household water flow rates.
Implementation Method 1
The water trap has the form of a cone which is tapered towards the inlet. The vortex is generated in a narrow inlet portion of the cone and is spreading towards a wide outlet portion.
Implementation Method 2
Due to the increasing diameter toward the outlet of the cone, the shape and the centrifugal force contributes to having particles and water moving faster towards the wide end of the cone.
