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

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

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

Key Metrics Rate of Importance

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

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

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

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

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

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

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

Prototype Cheaper than existing shell by over $160/unit EPDM Gasket ABS Shell EPDM Gasket Foam Insulation Heat Tracing Tape Internal Pipe 3.25”

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

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
