THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

TECHNICAL FIELD
[001] The present disclosure relates generally to the field of filter assembly, and more specifically, to a filter assembly with an end cap comprising recesses to receive the end plate.
BACKGROUND
[002] Filter assemblies comprise multiple parts arranged in a particular manner. In many instances, it is desirable to partially or completely redesign these components to overcome any difficulty observed in performance or efficiency. However, the design of a filter assembly and its components must fulfill the filtration quality criteria set by the user and the rate of filtration criteria required by the various mechanisms. Additionally, the design of a filter assembly and its components also must overcome constraints related to manufacturing processes and production lines. For example, end caps for filters having same/similar media are at times designed entirely different for specific needs of users but are manufactured on a single production line.
[003] The most challenging design problem which affects existing filter assemblies is twofold. The first relates to the design of an end cap supporting the filter media and the second relates to the design of an end plate receiving the end cap. Typically, end caps are designed in prior arts with protrusions or projections on their surfaces with custom-suited shape. These protrusions or projections are then typically received by the custom-shaped recesses in the end plate. The end plate is typically received by the tool holder of the embedder during the embedding process to complete the filter assembly.

[004] Traditionally, filter assemblies having foregoing protrusions or projections may not cater to such users or applications where any diaphragm or other such component is involved and which might be affected/damaged by such protrusions or projections. Further, filter assemblies with conventional designs having protrusions or projections on the end cap may even hamper a new functional design in cases where the design requirement dictates a flat end cap. If any selected design eliminates protrusions or projections, then another design problem arises as how to make an arrangement to assemble the end cap and the end plate together. Recesses might be used as an alternative to the projections or protrusions but they might also consecutively weaken the end cap. Thus, the recesses must be shaped in a geometry which allows engagement of the end cap and the end plate without weakening the end cap.
[005] Therefore, there is a need for a more cost and energy efficient design of a filter assembly which can have a flat end cap and supports easy assembly.
