Abstract
Official abstract text for this publication.
Methods and systems are provided for a retention system. In one example, the retention system comprises a retention feature arranged in each of a molded element and a fastener. The retention features interface with one another to enhance operation of the fastener.
First claim
Opening claim text (preview).
1 . A system, comprising: a retention feature of a molded element configured to interface with an undercut of a fastener. 2 . The system of claim 1 , wherein the retention feature is an annular protrusion. 3 . The system of claim 1 , wherein the undercut is a recess of the fastener. 4 . The system of claim 1 , wherein the undercut is arranged on a threaded portion of the fastener. 5 . The system of claim 1 , wherein the fastener comprises a head portion and a body portion. 6 . The system of claim 5 , wherein the body portion comprises a uniform diameter. 7 . The system of claim 5 , wherein the undercut corresponds to a reduction in the uniform diameter of the body portion. 8 . The system of claim 5 , wherein the body portion comprises a first body portion and a second body portion, wherein a diameter of the first body portion is greater than a diameter of the second body portion. 9 . The system of claim 8 , wherein the first body portion is threaded and the second body portion is free of threading. 10 . The system of claim 1 , wherein the fastener comprises a tooling pin at an extreme end of the fastener opposite a head portion. 11 . A retention system, comprising: a molded element surrounding a receiving feature and a fastener, wherein the molded element comprises a retention feature configured to interface with an undercut of the fastener. 12 . The retention system of claim 11 , wherein the molded element comprises plastic. 13 . The retention system of claim 11 , wherein the molded element encapsulates all of the receiving feature and the fastener except for a head portion of the fastener and a rim of the receiving feature. 14 . The retention system of claim 11 , wherein the receiving feature comprises an internally threaded bore and the fastener comprises threads configured to engage with the internally threaded bore. 15 . The retention system of claim 11 , wherein the undercut is arranged on a threaded portion of the fastener. 16 . A system, comprising: a retention feature of a molded element configured to interface with an undercut of a fastener, wherein the retention feature is an annular protrusion. 17 . The system of claim 16 , wherein the molded element comprises plastic, and wherein the molded element encapsulates all of the receiving feature and the fastener except for a head portion of the fastener and a rim of the receiving feature. 18 . The system of claim 16 , wherein the fastener comprises a first body portion and a second body portion, wherein a diameter of the first body portion is greater than a diameter of the second body portion. 19 . The system of claim 18 , wherein the first body portion is threaded and the second body portion is free of threading. 20 . The system of claim 16 , wherein the fastener comprises a tooling pin at an extreme end of the fastener opposite a head portion.
