This can lead to higher instances of broken connections in cases where the initially monitored connection was a precarious one.
  • Existing connectors aimed at the formation of more robust connections often include complex, complementary "pin" designs. While more prone to maintaining connections, such items are expensive to manufacture, and are also more prone to breakage during assembly, or in operation. Further, assembly of multi-connection articles using such pin- based items is more complex, as the complementary arrangement of pins and receptacles necessitates a precise approach, which may be exceedingly difficult to take in, for example, a close quarters environment. In addition, taking such an approach may serve to slow down associated and costly manufacturing processes, the costs of which rise as processing times increase.
