Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waste management systems, particularly vacuum-operated systems, face challenges in minimizing space requirements and energy consumption while effectively handling increasing waste volumes, as existing compaction solutions are expensive and inefficient in reducing space requirements.
Innovation Solution
A method and facility that utilize a tilted waste container with a self-compaction mechanism, leveraging gravity and waste weight to compact waste, eliminating the need for additional compaction equipment and separators, thereby reducing space and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional compaction equipment (hydraulic rams, compaction screws) is used to reduce waste volume, then waste volume is reduced, but device complexity and installation costs increase significantly
Solution Approach 1:
The patent extracts the compaction function from separate complex equipment and integrates it into the container support structure itself. The inclined support surface performs compaction through its geometry rather than requiring dedicated compaction devices, thereby eliminating complex hydraulic rams or screw mechanisms while achieving volume reduction.
Solution Approach 2:
The container support structure provides self-compaction functionality through its inclined design. As containers are placed on the inclined surface, their weight automatically compacts the waste inside without requiring external power sources or complex mechanisms. The system uses the containers' own weight to achieve compaction, making the process self-service and eliminating the need for additional compaction equipment.
2Productivity
If large transport pipes are used in vacuum systems to handle waste, then waste transport capacity is increased, but space requirements and energy consumption increase
Solution Approach 1:
The patent changes the density parameter of waste through compaction on the inclined support surface. By compacting waste before it enters the transport system, the same transport pipe capacity can handle larger amounts of waste, effectively increasing transport capacity without requiring larger pipes or more space.
3Quantity of substance
If temporary waste storage is increased at waste inlet locations to handle larger waste amounts, then waste handling capacity is improved, but space requirements increase
Solution Approach 1:
The patent changes the density parameter of stored waste through compaction. By compacting waste on the inclined support surface, the same storage volume can accommodate larger amounts of waste, effectively increasing handling capacity without requiring additional storage space.
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 doubles the waste capacity of standard containers, reduces the size of collection stations, and lowers operational and installation costs by simplifying the system without the need for complex compaction equipment, while allowing for efficient waste handling and storage.
Implementation Method 1
When entering an empty container (3) into a waste collection station (4) the container is positioned with a generally rectangular bottom wall (3A) thereof on an inclined surface (7) of the waste collection station, thereby tilting the container (3)... The tilting of the container (3) will cause waste introduced into the container through the waste inlet (5) to be compacted as it falls down in the lower rear corner of the rear end wall (3D)

AI summary
In a method of compacting waste (W), wherein waste is introduced into a generally box shaped elongated waste container (3) through at least one waste inlet (5) thereof and is collected in the waste container (3) at a waste collection station (4), the container is positioned with a generally rectangular bottom wall (3 A) thereof on an inclined surface (7) of the waste collection station, thereby tilting the container and its bottom wall, and releasably securing the container in the tilted position. A waste collection facility (13) of the waste collection station (4) is also provided.
