Project motivation

Project Motivation

  • DECO Windshield Repair – started in 2005

  • Similar concept to other companies

  • Main difference – reduce amount of theft possible

    • 1 syringe = 1 fix

    • Centralized inventory area

  • Exponential growth in Western Canada has created backlog


  • Functional objectives

    Functional Objectives

    • 1 – Prepare Syringe for Filling

      • Cap Removal

      • Re-useability check

  • 2 – Fill Syringe with Resin

    • Fill with 0.15mL of resin

  • 3 – Capping/Ejecting

    • Replace cap

    • Remove from system

  • 4 – Packaging/Labeling

    • Package in groups of 25

    • Label for shipping

  • Need to optimize process – whether that be 1 or all 4 of objectives


  • Project requirements

    Project Requirements

    Cost

    <18¢ / syringe including material and labour

    <7000$ machine including labour for 1 year

    Accuracy

    ±0.01mL or preferably less

    Speed

    >900 syringes / hour

    Reliability

    99% reliability of syringe production

    96% of availability of machine

    Compatibility

    Must be compatible with bridging device


    Concept generation

    Concept Generation


    Concept generation1

    Concept Generation


    Concept 1 shot gun

    Concept #1 – Shot Gun


    Concept 2 gripper

    Concept #2 – Gripper


    Concept 3 hopper

    Concept #3 – Hopper


    Concept 4 moulded tray

    Concept #4 – Moulded Tray


    Top 4 concept analysis

    Top 4 Concept Analysis

    • Each concept analyzed for the 4 functional objectives

      • Preparation (lid off, re-useability)

      • Filling

      • Ejection (lid on, remove from machine)

      • Packaging (bags, labeling)

  • Scale of 0-5, where

    • 0 = N/A

    • 1 = Below requirement

    • 3 = Meets basis requirement

    • 5 = Exceeds requirement

    • Each analyzed for requirement

      • Fulfillment (Fu)

      • Reliability (R)

      • Speed (S)

      • Feasibility (Fe)


    Final concept

    Final Concept


    Where we re headed

    Where we’re headed

    • Syringe / resin junction

      • how to ensure reliability?

  • Modularity

    • prevent complete system failure

  • Cap removal and replacement?

  • Force analysis

    • how much force required to pull 25 syringes?

  • Risk analysis


  • Questions
