Latest Patents

One of Harriman's latest patents is the "Vibration isolating attachment system for inkjet carriages." This invention involves an inkjet printing mechanism that includes a vibration isolating attachment system designed to secure a drive belt to an inkjet printhead carriage. The primary goal of this system is to improve print quality by isolating the carriage from multi-directional vibrations generated by the carriage drive motor during printing. The vibration isolating member is made of a resilient material, featuring a first end coupled to a drive mechanism interface member, a second end coupled to a carriage interface member, and a body section in between. The design allows for the use of two or more vibration isolating members, with a preferred I-shaped cross-section. This innovative mechanism not only enhances the printing process but also provides a method for isolating the inkjet printhead carriage from vibrations.
