Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid effluent treatment devices require complex, large, and expensive tank designs with high air injection flow rates, making them costly to manufacture and transport, and not suitable for portable or temporary installations.
Innovation Solution
A compact liquid effluent treatment module with a tank portion featuring a horizontal longitudinal axis, a central treated effluent collection ramp, and an eccentric air injection ramp, creating a spiral movement of effluents with reduced air injection flow rates, allowing for effective treatment in a minimized tank width and height, and eliminating the need for complex shapes and mechanical stirring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a complex tank shape with high width and height is used to allow good circulation of liquid effluents, then the treatment effectiveness is improved, but the manufacturing cost increases and the device becomes difficult to transport
Solution Approach 1:
The patent applies asymmetry by positioning the air injection ramp eccentrically (off-center) relative to the tank axis, creating an asymmetric flow pattern that generates spiral movement. This asymmetric configuration achieves effective effluent circulation without requiring a complex tank geometry, thereby reducing manufacturing costs and improving transportability while maintaining treatment effectiveness.
Solution Approach 2:
The patent transitions from conventional two-dimensional flow patterns (horizontal or vertical) to three-dimensional spiral flow by introducing the eccentric air injection ramp. This dimensional change creates a rotational component to the flow, enhancing mixing and treatment effectiveness within a compact tank configuration that is easier to manufacture and transport.
2Productivity
If a high air injection flow rate is used to achieve good effluent circulation, then the treatment effectiveness is improved, but the operating cost increases
Solution Approach 1:
The eccentric positioning of the air injection ramp creates asymmetric flow patterns that generate spiral movement and enhance mixing efficiency. This asymmetric configuration improves treatment effectiveness at lower air injection flow rates, thereby reducing the energy required for aeration and lowering operating costs.
Solution Approach 2:
The spiral flow pattern generated by the eccentric air injection ramp creates self-sustaining circulation patterns that enhance mixing and treatment without requiring additional energy input. The system leverages the inherent dynamics of the spiral flow to maintain effective effluent circulation at reduced air injection rates.
3Ease of manufacture
If a simple tank shape is used to reduce manufacturing cost, then the ease of manufacture is improved, but the effluent circulation becomes insufficient
Solution Approach 1:
The patent uses pneumatic principles by introducing air through the eccentric injection ramp to generate spiral flow patterns. This pneumatic mechanism enhances effluent circulation within a simple tank geometry, achieving effective mixing and treatment without requiring complex tank shapes, thereby maintaining manufacturing simplicity while improving productivity.
4Length of moving object
If a compact tank design with reduced width and height is used to facilitate transportation, then the transportability is improved, but the effluent circulation space is reduced
Solution Approach 1:
The eccentric air injection ramp creates asymmetric spiral flow patterns that maximize the utilization of available tank space. This asymmetric configuration enhances mixing efficiency and effluent circulation within the compact dimensions, achieving effective treatment in a reduced-volume tank that is easier to transport.
Solution Approach 2:
The patent introduces a rotational dimension to the flow pattern through the eccentric air injection, creating three-dimensional spiral movement within the compact tank. This dimensional enhancement allows effective effluent circulation in a reduced-width and reduced-height configuration, facilitating transportation while maintaining treatment productivity.
