Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for treating organic material using wheel loaders result in prolonged exposure and significant odor emissions during the turning-over process, leading to unpleasant olfactory pollution in the surrounding environment.
Innovation Solution
An aerobic method utilizing a turning-over device with a membrane-holding and membrane-laying apparatus, where the organic material is covered with odor-reducing membranes, and the turning-over device moves along the treatment unit's longitudinal extent, minimizing exposure and odor release by continuously supplying air and switching membranes during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheel loaders are used for turning over organic material in treatment units, then the material can be mixed and homogenized, but the material is exposed to air for several hours causing significant odor emissions
Solution Approach 1:
The patent applies flexible membranes (thin films) to cover the organic material during turning over operations. The membrane holding apparatus secures the membrane over the material while the turning-over device operates, preventing odor emissions. The membrane is then removed and a fresh one is applied, creating a temporary enclosure that eliminates odor problems while maintaining operational efficiency.
2Productivity
If the treatment unit length is increased to accommodate wheel loader operations, then more material can be processed, but the exposure time and odor emission duration increase proportionally
Solution Approach 1:
The patent extracts the membrane application function from the turning-over operation itself by introducing separate membrane holding and laying apparatus. This allows the membrane to be applied, removed, and reapplied independently, decoupling the odor protection function from the material handling time, thereby reducing overall exposure duration without limiting treatment unit capacity.
3Stability of the object's composition
If frequent turning over operations are performed to maintain material homogeneity, then treatment effectiveness is improved, but odor emissions occur more frequently
Solution Approach 1:
The patent applies the preliminary action principle by covering the material with a membrane before turning over operations begin. This pre-established enclosure ensures that regardless of how frequently turning over is performed to maintain homogeneity, the material remains enclosed and odor emissions are prevented from the outset of each operation.
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 approach significantly reduces odor emissions by maintaining the organic material under a membrane during turning, limiting exposure to a small area behind the turning-over device, thus minimizing environmental pollution.
Implementation Method 1
a turning-over device is used for the turning over, which is moved along the direction of longitudinal extent (X) of the treatment unit and thereby turns over the organic material by means of a turning-over roller, wherein the turning-over device has a membrane holding apparatus, which holds the first membrane covering the organic material during the conversion
Implementation Method 2
a membrane laying apparatus which lays a moisture-permeable and/or air-permeable but at least odor emission-reducing second membrane on the turned-over organic material
Implementation Method 3
aerobic treatment of the organic material by actively supplying air to the organic material and the supplied air flowing through said organic material
