Abstract

A system for increasing stiffness and/or strength of a light-duty machine component having propensity for flexing along an elongated axis is provided. The system includes a pair of receptacles disposed on the machine component, wherein each of the receptacles is located in a spaced apart relation to one another and disposed parallel to the elongated axis. The system further includes at least one backing member corresponding to a distance between the pair of receptacles. The backing member is configured to define at least a pair of openings therethrough. The pair of openings is configured to axially align with the pair of receptacles defined on the machine component. The system further includes a plurality of fasteners such that at least one fastener is received in each pair of axially aligned receptacles and openings for releasably securing the backing member to the machine component.

First claim

What is claimed is:

1. A system for increasing stiffness of a single light-duty machine component having propensity for flexing along an elongated axis, the system comprising:
a pair of support members protruding from an outer surface of the single machine component and having at least a pair of receptacles located thereon, the support members being spaced apart relation to one another and disposed on opposite ends of the single machine component, wherein each of the support members is located in a spaced apart relation to one another and disposed parallel to the elongated axis;
at least one backing member corresponding to a distance between the pair of receptacles, the backing member defining at least a pair of openings therethrough, wherein the pair of openings are configured to axially align with the pair of receptacles defined on the single machine component; and
a plurality of fasteners, wherein at least one fastener is received in each pair of axially aligned receptacles and openings for releasably securing the backing member to the single machine component.

2. The system of claim 1 , wherein the backing member is configured to operably resist flexing of the single machine component along the elongated axis.

3. The system of claim 1 , wherein the receptacles are defined on an outer surface of the single machine component.

4. The system of claim 1 , wherein a portion of the backing member, disposed partway along a length of the backing member, is configured to resiliently abut with the single machine component.

5. The system of claim 1 further comprising a plurality of sensors disposed on the machine component, the sensors configured to:
measure an amount of operative load on the single machine component; and
provide feedback based on the measured operative load.

6. The system of claim 5 , wherein the feedback from the sensors is determinative of releasably affixing additional backing members to the single machine component.

7. A system for increasing stiffness of a light-duty machine component having propensity for flexing along an elongated axis, the system comprising:
at least a pair of receptacles disposed on the machine component, wherein each of the receptacles is located in a spaced apart relation to one another and disposed parallel to the elongated axis; and
at least one backing member corresponding to a distance between the pair of receptacles, the backing member including:
a pair of ends configured to releasably engage with the pair of receptacles defined on the machine component; and
a portion of the backing member disposed partway along a length of the backing member, the portion configured to resiliently abut with the machine component.

8. The system of claim 7 , wherein the backing member is configured to operably resist flexing of the machine component along the elongated axis.

9. The system of claim 7 further comprising at least a pair of support members protruding from an outer surface of the machine component, wherein each of the support members is located in a spaced apart relation to one another and disposed parallel to the elongated axis.

10. The system of claim 9 , wherein the receptacles are located on the support members.

11. The system of claim 7 , wherein the receptacles are defined on an outer surface of the machine component.

12. The system of claim 7 further comprising a plurality of sensors disposed on the machine component, the sensors configured to:
measure an amount of operative load on the machine component; and
provide feedback based on the measured operative load.

13. The system of claim 12 , wherein the feedback from the sensors is determinative of releasably affixing additional backing members to the machine component.

14. A method for increasing stiffness of a light-duty machine component having propensity for flexing along an elongated axis, the method comprising:
defining at least a pair of receptacles on the machine component such that each of the receptacles is located in a spaced apart relation to one another and disposed parallel to the elongated axis;
determining, using sensors provided on the machine component, if the machine component is being used in a light-duty application or a heavy-duty application;
if a controller, communicably coupled to the sensors, determines that the machine component has reached a threshold of the heavy-duty application, then positioning at least one backing member on the machine component such that:
a pair of ends of the backing member are configured to releasably engage with the pair of receptacles defined on the machine component; and
a portion of the backing member, disposed partway along a length of the backing member, is configured to resiliently abut with the machine component.

15. The method of claim 14 further comprising defining at least a pair of support members on an outer surface of the machine component, each of the support members being located in a spaced apart relation to one another and disposed parallel to the elongated axis, wherein the pair of receptacles are located on the pair of support members.

16. The method of claim 14 further comprising defining the backing member with at least a pair of openings therethrough, the pair of openings configured to axially align with the pair of receptacles defined on the machine component.

17. The method of claim 14 further comprising releasably securing the backing member to the machine component by providing a plurality of fasteners, wherein at least one fastener is received in each pair of axially aligned receptacles and openings.

18. The method of claim 14 , wherein the sensors on the machine component are configured to:
measure an amount of operative load on the machine component; and
provide feedback based on the measured operative load, wherein the feedback from the sensors is determinative of releasably affixing additional backing members to the machine component.
