3. Phase 0: PlanningMission Statement Product Description This product is a device that can mark tiles for cutting that are to be laid against a wall. It enables many tiles to be marked at once, and marks them according to the exact contour of the wall. Currently it is only for linoleum tile, but expansion to ceramic time is expected. Key Business Goals The primary business goals of this product are to -enable contractors and users of the device to mark tile more efficiently, cutting down on the time needed to finish a job. -increase the profitability of a tiling job to the company that its contracted to. become a source of revenue for the product’s inventor: Eula Dozier. -make it easier for the average person to get clean and correct cuts the first time, every time. Primary Market This product’s primary market is composed of professional contractors who lay large quantities of tile on a regular basis. Secondary Market The secondary customer base contains all other types of people who could be laying tile- this includes the “do-it-yourselfers,” smaller scale contractors, and remodelers. Stakeholders Professional Tiling Contractors “Do-it-yourselfers” Hardware/ Home Stores Tile manufactures Home owners & businesses having tile work done General contractors & Spec home builders Home Improvement TV Shows- such as Hometime & This Old House who may showcase the tool

4. Phase 0: PlanningStaffing Requirements Mechanical Engineers 3-4 This device is purely mechanical as there are no electrical or computer components implemented into this device. Mechanical engineers would be needed to figure out the parts that are needed to help the device follow the contour of a wall, slide along the edge of tiles, and mark the tiles. They are also needed to help figure out how to mark inner and outer corner tiles. Electrical Engineers 17 There are currently no plans for, or existing electrical components used in this device so there is no need for an electrical engineer at this point in time. Industrial and Systems Engineers 1 There are no systems used in this device, however an IE will be helpful with the ergonomics of the device. There will also need to be a coherent user’s manual to accompany the product on the shelf, and possibly testing protocols to be written and performed. Computer Engineers 0 There is no software used in this device so there is no need for computer engineers at this point in time. Business Majors 1-2 Mr. Dozier would eventually like this product to be available for the public to purchase, so business majors would be able to define a business plan and increase the marketability of the product. Industrial Design Majors 1 At this point in time, the prototype is very rough and not too appealing to the eye. An ID could help make the look of the device more appealing to the customer. It would be helpful if this ID had an interest or background in product prototyping.

5. Phase 0: PlanningResource Requirements People -Eula Dozier (inventor) -SD Team (4-8 members) -Faculty Advisor & Guide (consultants) -Tile Contractors (industry contacts) Environment -SD cubby -Open floor testing space -Construction site (onsite testing) Equipment -Machine shop -Computers with design software -Rapid prototyping equipment -Mr. Dozier’s prototype -Mr. Dozier’s testing fixture -Challenging wall profile testing fixture Materials -Variety of tiles -Tile laying materials -Standard machining materials -Vendor components

6. Phase 1: Concept DevelopmentIdentify Customer Needs - Interviews Primary Customers Eula Dozier (inventor) Inspired to develop prototype after observing a tile layer as a general contractor with no tiling experience. This 2nd generation prototype is patent pending and functions to mark linoleum tiles accurately to a wall profile. Patent info, CAD files, prototype, and testing fixture are in RIT hands and accessible to all tile project teams. Tile Contractors (users) TO BE INTERVIEWED A.S.A.P Prototype was designed to a limited set of needs and more must be uncovered through dialog and observing users in their environment. Photos, video, and sketches will be utilized. Other Stakeholders Do-It-Yourself Consumers TO BE INTERVIEWED at a later point in the product development process Flooring Tool Vendors TO BE INTERVIEWED at a later point in the product development process ex. Home Depot, Lowe’s Home Improvement, and professional suppliers Previous Projects NO similar SD projects exist Eula Dozier’s Prototype – addresses the need for tile laying innovations to reduce labor efforts Existing flooring tools – none available that are as innovative Polygraph machine from Thomas Jefferson’s collection – exists as technological inspiration.

7. Phase 1: Concept DevelopmentIdentify Customer Needs - Benchmarking Competitive or Cooperative Solutions The benchmarking for this project will be somewhat alternative to what other senior design teams will conduct. A comparative rather than a competitive benchmarking solution will have to suffice. Benchmarking will serve more as a means to express the problem and aid in its definition, rather than a way to gather competing design information. A trip to the local hardware store has already been conducted and information about the available “tools of the trade” was probed. Several key ideas were established: • When asked “what tool do I use to layout a tile to be cut?” the sales associate responded “a china marker” • Tools with similar functions to the prototype were not able to be purchased. • Lesser tools used together are current technology for tile layouts. Internet Search The internet is a limitless treasure trove of DIY info. Curiously, the internet is partial when it comes to professional techniques and commercial flooring systems. • The internet has even revealed a basic marking tool: http://www.tiletool.net/Marking_Tools.asp • The RIT library Engineering Data Bases: http://wally.rit.edu/electronic/topic/engineering.html • The traditional industrial suppliers: McMaster Carr: www.mcmaster.com (everything you need to thrive in industry) MSC: www.mscdirect.com (everything you need in industry with special attention to specific markets) Misumi: www.misumiusa.com (parts and hardware for the machine design industry, metric components) Technical Literature Search It would be useful to add “technical personnel” to this heading. Much of the tile laying trade is based on the techniques of a professional. And much of the information that’s of the highest importance to this product and its ultimate success in the market place comes from these people. There are a variety of D-I-Y books and informational media that cover similar topics on tile laying and the layout process It is also important to identify relevant consumer product standards. An important part of this project, this area of technical literature has not been exploited as of yet.

12. Future PlanWhere do you go from here? 1) Identify key personnel that would likely provide first-hand insight as to the needs of a professional on the job. • These persons would also be likely to offer design recommendations, and ergonomic considerations • This person would also be a customer of our product. • One of the results of the initial customer interview was the need to find an experienced individual or individuals that can offer impartial information on the process to be solved. 2) Interview contractors and tile layers for end-user needs. 3) Talk to management at Home Depot and Lowe's about publishing in Do-It-Yourself books. 4) Talk with faculty to confirm advisor choices.
