Overview

  • The Sparx ice skate sharpener is an electro-mechanical device, relying on several electronics to control and operate the mechanical components

  • Once the mechanical design stage of development and a Top Level Assembly with all parts included were completed, drawings had to be created for electrical components for suppliers that provided wire specifications and lengths

  • Sparx main PCB control board utilized JST connectors for quick connect/disconnect; thus, electrical drawings had to include these with proper orientation

Example of limit switch wire harness with component and 3D wire routing, for determining wire and heat shrink tubing length as well as for visual indication during assembly

Process

  • List of 10+ electro-mechanical components within Sparx sharpener that needed specified wire lengths and production drawings was generated

  • Used top level assembly of Sparx sharpener to interpret placement of all electronics and spec wire lengths for production

  • Used SolidWorks configurations to create three versions of all electronic devices- component only, component with 3D wire routing, and component with straight wires for 2D production drawings

complications

  • Had to learn design of simple electrical circuits and custom Sparx PCB to understand wiring

  • Wire harnesses were not created with master modelling like the rest of the assembly, and thus changes had to be manually updated with each design change

Results

  • Created 2D production drawings for all electro-mechanical components within Sparx sharpener

  • Specified wire orientation for JST connectors’ attachment to PCB and routing through machine

Skills Developed

  • Knowledge of electro-mechanical product specifications and PCB connections

  • Use of advanced SolidWorks Configurations feature to create multiple variations of each part
