Abstract: An apparatus for designing a tubing configuration comprising modules that receive tube design input, interpret a tube design input, calculate a final tube design, and display a final tube design. The tube design input may include point locations, bend criteria and end conditions, among others. The apparatus may further include modules that determine whether the tube design input exceeds a complexity threshold, comprises a minimum set of information, and comprises a conflicting or erroneous design. The apparatus may further include modules that determine and optimize the manufacturing cost as well as determine the manufacturability of the tube. The apparatus may further include modules that store operational challenges corresponding to emissions reduction features and secondary components.

Abstract: A housing, which may be a filter housing, has break-away lock structure preventing movement in response to normal release force, and breaking-away from a housing section upon excessive release force, such that the housing may be re-assembled using the same housing sections, without having to use a new housing section to replace an old housing section otherwise having a non-re-mountable broken-off lock member.

Abstract: A filter media and liner pleat block and method involves melting the filter media at mating pleats to form a closed-loop-bonded filter media and liner pleat block.

Abstract: An apparatus, system, and method are disclosed for rapid design of emissions component installations. The method assists in the rapid design of emissions component installations by: interpreting a tube design input which may be an exhaust pipe with one or more aftertreatment components, calculating a final tube design and tube drawing, determining the manufacturability of the final tube design, determining the manufacturing cost of the final tube design, and displaying the drawing, manufacturability result, and manufacturing cost to a user. The method also evaluates the final tube design for portions that can be replaced with a more cost effective alternative. The method also receives the emissions reduction features of the installation from the user, and recommends secondary components to mitigate operational consequences, such as reduced fuel economy or reduced oil change intervals, of the emissions reduction features.
