Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shredding devices face issues with clogging and blockages in pipe systems due to large shredded waste parts, and have complex constructions with permanent open connections to the sewer, leading to odor nuisances and hygiene concerns.
Innovation Solution
A shredding device with an adjustable closing device using a flexible membrane and a controller unit to manage the flow of shredded waste and transport liquid, eliminating the need for additional conveyors and ensuring a closed connection to the sewer, featuring a transport liquid feed that maintains waste in suspension and a swing element for enhanced shredding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a known shredding device is used to shred waste, then the waste is processed and ready for discharge, but the shredded waste causes clogging and blockages in the pipe system
Solution Approach 1:
The closing device uses a flexible membrane that can dynamically adjust its position between open and closed states, allowing the system to adapt to the presence of shredded waste and prevent blockages while maintaining processing capability
Solution Approach 2:
The system changes the flow state parameters by using a transport liquid to transform the discharge from a simple gravity flow to a pressurized flow that can carry shredded waste through the pipe system without clogging
2Device complexity
If a known shredding device with open connection to sewer is used, then waste discharge is simple, but odor nuisance and hygiene problems occur
Solution Approach 1:
A flexible membrane is used to create a closed connection between the receiving space and sewer, preventing odor escape while maintaining a relatively simple discharge structure that can still handle shredded waste
Solution Approach 2:
The closing device acts as an intermediary between the receiving space and sewer, allowing controlled discharge while maintaining a closed connection that prevents odor nuisance and hygiene problems
3Reliability
If a conveyor is added to discharge waste actively, then waste discharge is improved, but the construction becomes complex
Solution Approach 1:
The system uses hydraulic principles by introducing a transport liquid to create a flow that actively carries shredded waste through the outlet, replacing the need for mechanical conveyors while maintaining reliable discharge
Solution Approach 2:
The mechanical conveyor system is replaced with a hydraulic flow system using transport liquid, achieving active waste discharge without the complexity of mechanical conveying components
4Object-generated harmful factors
If a closing device is added to close the sewer connection, then odor and hygiene are improved, but the device complexity increases
Solution Approach 1:
A flexible membrane is used as the closing element, providing an effective seal to prevent odor and hygiene issues while maintaining a relatively simple closing device structure without complex mechanical components
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
The solution reduces the risk of blockages and odor issues by efficiently discharging shredded waste into the sewer, maintaining a closed connection, and preventing waste deposition, thus ensuring smooth operation and improved hygiene.
Implementation Method 1
a flexible element, in particular a flexible membrane, arranged in the closing device housing and connected to the entrance and exit, wherein the flexible element is embodied to form an adjustable passage between the entrance and exit
Implementation Method 2
a transport liquid feed embodied to feed transport liquid to the receiving space
Implementation Method 3
a controller unit for displacing the flexible element between a closing position, in which the membrane closes the passage between the entrance and exit, and an opened position in which the flexible element leaves a passage clear between the entrance and exit
Implementation Method 4
The mixture of shredded liquid and solid material waste and transport liquid preferably flows under the influence of gravitational force directly from the receiving space to the sewer
