Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If replaceable disposable filter modules are used for overspray separation, then ease of operation and reliability are improved, but loss of substance and loss of energy increase due to frequent disposal and replacement
Solution Approach 1:
The filter module is designed with a reusable structure that can be thermally regenerated. After saturation with overspray, the filter module is subjected to thermal treatment that decomposes the captured particles, allowing the filter structure to be reused multiple times instead of being disposed of after single use.
Solution Approach 2:
The filter module undergoes thermal treatment parameter changes to regenerate its capacity. By applying thermal energy, the captured overspray is decomposed and removed, restoring the filter's separation capability without requiring replacement of the entire filter structure.
2Ease of operation
If replaceable disposable filter modules are used for overspray separation, then ease of operation is improved, but loss of energy increases due to disposal and replacement processes
Solution Approach 1:
The thermal energy required for regeneration is obtained by burning the captured overspray material itself. The overspray that would otherwise be waste is converted into a fuel source, generating the heat needed for its own decomposition and removal from the filter, thereby eliminating external energy input for the regeneration process.
3Loss of substance
If thermally regenerable reusable components are used in filter modules, then loss of substance and loss of energy are reduced, but device complexity increases
Solution Approach 1:
The filter module performs its own regeneration by utilizing the captured overspray as fuel for thermal decomposition. The system is self-sufficient, requiring no external energy sources or complex regeneration equipment, as the overspray itself provides the necessary thermal energy for its removal from the filter structure.
4Loss of energy
If thermally regenerable reusable components are used in filter modules, then loss of energy is reduced, but device complexity increases
Solution Approach 1:
The filter module performs its own regeneration by utilizing the captured overspray as fuel for thermal decomposition. The system is self-sufficient, requiring no external energy sources or complex regeneration equipment, as the overspray itself provides the necessary thermal energy for its removal from the filter structure.
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 the effort and costs associated with filter module disposal while maintaining effective separation, allowing for on-site thermal treatment of overspray and utilization of the thermal energy for secondary processes such as electricity generation or drying.
Implementation Method 1
a thermally regenerable reusable component is a component that can withstand a thermal treatment, in which existing overspray is thermally decomposed and thus removed from the filter module
Implementation Method 2
a thermally decomposable disposable component is also degraded during a thermal treatment in which existing overspray is thermally degraded

AI summary
The invention relates to a filter module for trapping overspray from booth air laden with overspray from coating facilities, particularly from painting facilities, having a module housing, in which a filter structure (88) is accommodated and which has a module inlet (74) and a module outlet (76), wherein the filter module (40) is designed in such a manner that it is swapped for an empty filter module (40) once a limit loading of overspray is reached. The filter module (40) comprises a recyclable reusable structure (112) of one or more reusable components that can be thermally regenerated and therefore the filter module (40) can at least partially be thermally regenerated. The invention also relates to a trap having one or more filter modules of this kind, a coating facility for coating objects (14) and to a method for operating a coating facility.
