Solution Overview
Problem
Existing methods for leaching toxic substances from inorganic binder-stabilized solid waste materials require crushing the materials into fine particles and simulating leaching using a horizontal oscillator, which does not accurately represent actual working conditions, such as rainy weather on roads.
Innovation Solution
An apparatus and method that include a specimen placement box with an angle adjustment apparatus, a water supply and drainage system with temperature control, and electromagnetic regulating valves, allowing for leaching of toxic substances in a condition that mimics actual highway conditions, such as inclination and water temperature, without the need for crushing the specimens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the horizontal oscillator method is used to leach toxic substances, then the leaching process can be completed, but the detection effect is greatly reduced and it does not align with actual working conditions
Solution Approach 1:
The patent changes the key parameter of the leaching method from horizontal oscillation to inclined plane water flow simulation. By adjusting the inclination angle of the specimen placement box to match actual road slopes and controlling water flow rate and temperature, the method creates leaching conditions that accurately represent real highway environments during rainy weather, thereby improving both detection accuracy and reliability simultaneously
Solution Approach 2:
The patent creates a simplified copy of actual highway conditions by constructing a specimen placement box that replicates the inclined surface of a road. Water flow is directed over the specimen at controlled rates and temperatures to simulate rainwater leaching, providing an accurate yet controllable model of real-world conditions without requiring actual field testing
2Ease of manufacture
If specimens are crushed into fine particles, then the leaching process can be standardized, but it does not align with actual working conditions and reduces detection effectiveness
Solution Approach 1:
The patent introduces dynamic control elements including adjustable water flow rates, variable inclination angles, and temperature control to create a flexible leaching system. This allows the method to adapt to different specimen types and environmental conditions while maintaining standardized testing protocols, resolving the conflict between standardization and detection accuracy
