Nested Classifying Sieves for Dry and Wet Material Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing classifying kits for separating gold, gems, rocks, and artifacts from earth material are cumbersome for transportation, difficult to use for wet separation, and lack a water exit mechanism, limiting their effectiveness in both dry and wet filtering methods.
Innovation Solution
A kit comprising a bucket with a top aperture, multiple classifying sieves with progressively finer mesh sizes, a funnel, a sluice section, and a base bowl, allowing for both dry and wet separation methods, with a drainage system for efficient water management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple exposed sieves are stacked upon each other, then size-based separation is achieved, but portability and ease of operation deteriorate
Solution Approach 1:
The patent implements nesting by placing smaller-diameter sieves inside larger-diameter sieves, with each sieve fitting within the previous one. The inner perimeter of each sieve is smaller than the outer perimeter of the sieve above it, allowing compact stacking. This nested configuration enables easy portability while maintaining multiple size-based separation stages.
2Measurement precision
If multiple exposed sieves are stacked upon each other, then size-based separation is achieved, but wet separation capability deteriorates
Solution Approach 1:
The patent achieves multi-functionality by designing the sieve system to support both dry shaking and wet sluicing operations. The nested sieve structure allows water to flow through all sieves during sluicing, enabling wet separation. The same apparatus that performs dry size-based separation also functions as a wet sluice box, eliminating the need for separate equipment.
3Adaptability or versatility
If a water exit hole is added to enable wet separation, then wet separation capability is improved, but structural complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the water exit function into multiple locations - one water exit hole in each sieve. This distributed approach allows water to drain efficiently from each separation stage independently, simplifying the overall water management system compared to having a single centralized exit point at the bottom of the stack.
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
Enables efficient separation of materials by size and weight, improving portability and usability, and allowing for effective wet separation techniques, such as sluicing, enhancing the ability to classify and recover valuable materials like gold and gems.
Implementation Method 1
a first classifying sieve having a mesh screen surrounded by a perimeter and configured to be removably positioned inside the main cavity near the top aperture of the bucket
Implementation Method 2
allowing for sluicing, such as when a user wishes to further separate small objects from water based on weight
