  1. SE-6000 OutdoorSafety Shower Shell Mike Fuqua Colby Janisch Ryan Kobos Steve Opsitnick Joey Tordella

  2. Sponsor Goal / Project Scope • Improve existing SE-6000 safety shower to be more appealing to market • Reduce costs and labor • Update/improve current design of SE-6000 Outdoor Safety Shower • Focus on improving shell and seal • Improve insulation

  3. Current Shell Design • 18 x 3’’ ID PVC pieces • Long assembly time • Difficult maintenance • Custom made for various options

  4. Wants and Requirements • Speakman’s Requirements • Easy Access Shell • No painting • Modular • Weatherproof • Retain durability • Minimize cost • Customer Wants

  5. Rate ofImportance Key Metrics

  6. Benchmarks • ABS plastic shell • Vacuum molded • Clamshell seal • Pros • Easy assembly • Less costly than PVC • Cons • Clamshell seal • Not watertight

  7. Forming Methods • Structural Foam • Very precise • High stiffness ratio • Very expensive molding and tooling costs • Vacuum Forming • Accurate • Low cost • All necessary properties are possible

  8. Sealing and Fastening Methods • Fasteners • Latches • Slide Pins • Zip ties • Spring loaded clamps • Ratcheting ties • Compression pins • Bolt and Fastener • Gaskets • K profile EPDM • P profile EPDM • High density PVC foam • EPDM foam rubber • Polyurethane foam rubber • EPDM, Neoprene, and SBR foam

  9. Concept Selection • Vacuum formed outer casing • ABS plastic • Internal gasket seal • Reusable nylon rivets • Pre-slit Armacell pipe insulation

  10. Exterior Shell Design • Incorporate all options into shell • Use rounded edges to avoid sharp corners • Part mating

  11. Sealing Testing • Gaskets and grommets tested for water tightness under 4.5 GPM for 30 minutes

  12. Sealing Selection • ¾” wide by 1/8” thick EPDM Closed Cell Foam Strip • Temperature rating -90o to 257oF • Self adhesive backing: Temperature rating -40o to 250oF • Rubber Lip Seal Grommet

  13. EPDM Gasket Internal Pipe ABSShell Foam Insulation Heat Tracing Tape Prototype • Cheaper than existing shell by over $160/unit 3.25”

  14. Prototype vs. Competition • Similar shell design • New innovative sealing method • New fastening method • Better sealing of protrusions >

  15. Path Forward • Fix problems with dimensions • Test in outdoor environment • Prepare assembly instructions to decrease factory installation issues and reduce production time • Develop shipment method • Begin production in spring 2006
