user needs // market segments We divided the shredder market into three segments and identified an un-met user need for each.

Home Office Need: Storage The home office segment needs a method to store paper until it is shredded.

Small Office Need: Convenience Small offices need the shredder to be faster and more convenient. one wants to count out 12 of paper in order to keep the machine from jamming.

4 user needs // market segments We divided the shredder market into three segments and identified an un-met user need for each. Home Need: Safety For the home segment, safety is a user concern that is not being fully addressed. People want shredders that are explicitly safe especially with regards to children. Home Office Need: Storage The home office segment needs a method to store paper until it is shredded. Few users shred sensitive materials as they receive it; instead they collect it into pile and shred the entire stack at a later date. Small Office Need: Convenience Small offices need the shredder to be faster and more convenient. one wants to count out 12 of paper in order to keep the machine from jamming. Women Middle income Household w/ children Keep shredder in den or closet Purchased shredder for mail, bills and personal information Concerned about safety of shredder around kids and pets Women Middle to upper income Own their own business Keep shredder in home office Purchased shredder for business records, mail, bills and personal information Busy with running a business, shredding is put off until last minute Men Middle to upper income Own their own business Keep shredder in a common office area Purchased shredder for sensitive business data. Wants speed and efficiency. Can t wait around to feed paper into a shredder Brian Brigham John Ekholm ID547 Product Architecture and Platform 4

5 platform strategy // component breakout The mechanical assembly consisting of the cutter body, motor and CD is the core of the platform strategy. The cutter body is the base platform on which a variety of motor sizes can be plugged in and the CD module added. For the proposed product line, the top housing and bottom housing are common parts that are used throughout the product family. The face plate, bin and motor are the elements of the platform that are switched out to provide for the differing needs of the home, home office and small office. Top housing Face Plates Cutter body Motors CD shredding module Bottom housing Bins Common parts Differentiated parts Brian Brigham John Ekholm ID547 Product Architecture and Platform 5

platform strategy // product line In addition to the efficiencies of manufacturing and reduced number of tools (molds), the platform strategy also enforces a unified design language.

11 platform strategy // product line In addition to the efficiencies of manufacturing and reduced number of tools (molds), the platform strategy also enforces a unified design language. The size and shape of the shredder head are set, but the parts that provide the added benefits of safety, storage, and convenience are configured in such a manner to create a product line that hits several price points.

product analysis // paper shredder Our analysis began with the disassembly of an existing paper shredder in order to understand the architecture of the underlying components.

13 product analysis // paper shredder Our analysis began with the disassembly of an existing paper shredder in order to understand the architecture of the underlying components. The product we disassembled was a crosscut style shredder claimed to be able to shred 10 (experimentation proved 8 to be a more realistic limit) as well as credit cards. Externally, the shredder consists of a plastic housing containing the shredding mechanism which sits atop a plastic bin intended to catch the shredded documents. The external housing includes a combination on/off/reverse switch with a safety lock mechanism, a power LED, overheat LED, and slots for feeding paper and credit cards into the shredding mechanism.

16 product analysis // components schematic diagram inputs paper power/energy feedback paper paper sensor power bin sensor on/off switch controller board motor gears blades temp sensor power LEDs overheat LEDs This functional diagram indicates the functioning of the shredder. At the most basic level paper flows into the shredder, triggering the paper-sensor, and then passes through the shredder s blades and into the trash bin. The flow of power is slightly more complex. Power enters the shredder via the power cord and is transmitted to the bin sensor, which interrupts the power supply if the trash bin is not attached to the bottom of the shredder unit. After the bin sensor, power passes through the on/off switch and is distributed to the paper sensor and the main controller board. If paper or a credit card activates the paper sensor, a signal is transmitted to the controller board which, in turn, sends power to the motor. The shredder s motor then drives a system of reduction gears which rotate the cutting blades, shredding the document. trash bin output Within this system, user feedback is provided by two LEDs on the main shredder housing. Whenever the on/off switch is in the on position, the power LED is illuminated, indicating that the shredder is receiving power. During shredding, a temperature sensor monitors the motor s operating temperature. If the temperature exceeds a predetermined level, the sensor sends a signal to the main controller board, which shuts the motor down, and illuminates the overheat LED to indicate the status to the user.
