Table of contents • Definition of Needs and Requirements • Competing Preliminary Conceptual Options • Weighted Selection Matrix • Design Features of Final concept
Definition Of Needs And RequirementsStack Quality Detection Needs- The stack mush have a uniform shape - Two types of good stacks Simple stack (no offset) Offset stack Requirements- A design and model/ prototype of the stack quality detection system • The project must detect the 2 goods stack and 2 bad stacks as defined below. Stack Quality- The stack is supposed to have a uniformed shape.
Detailed Description of Competing Preliminary Conceptual Options Concept 1: Multi Shelving • This option would be able to detect and function properly with various paper sizes, weights and thicknesses. The multi shelving system would provide the ability to offset stacks of paper (50 sheets per stack) prior to printing by programming the desired offset into the printer program. • This system would be moderately expensive and harder to integrate into the existing printer. Also it contains many mechanics and other moving parts in order to work correctly. Therefore in case of a failure in any of these parts would result in the failure of the system as a whole. Concept 2: Single Stack Mechanical Tray • This is the most cost efficient of all the concepts and would allow easy integration into the existing system. The single stack tray, likes its name states, would only be able to stack sheets without an offset. Also this concept would not be suitable for various sizes of paper or different formats.
Preliminary Conceptual Options Cont. Concept 3: Offset Belt Feed • A belt feed systems with programmable offset features allows for various sizes, weights, and thicknesses of paper. Also this system will allow the user to program the offset of the stack prior to printing. • The belt feed system consists of many moving parts making it susceptible to wear and tear over time. This system would be more difficult to integrate into the existing system but once it replaced the current feed belt, nothing more would have to be changed on the system. Concept 4: Attachable Shelving Bins • This system is very cost efficient and easily integrated into the existing system. It allows for easy transport to a third party due to its design of not being directly attached to the printer system. Attaches to the printer by a cable which is used to receive programmed information from the computer such as the count of pages being printed so the device knows when to switch shelves (every 50 sheets). • Like the other concepts, this one also contains moving parts which may receive wear and tear over time. Also the user must remember to attach the info cable before printing to allow the device to change every 50 sheets and then remove the cable before transport to avoid damage to the device or the printing system.
Design Features This makes it easier to handle by the customer. It enables the stack to be transferred easily to a third‐party. Cost efficient and easily integrated into the system that exists. It will allow for a large amount of papers to be printed, stacked, and moved at one time.
User would have to plug info cable from paper stacking device to printer. • Doing this would allow to count the sheets of paper while it is printing. • After printing is complete, user disconnects info cable and moves the shelving bin to a third-party destination. • Therefore, the paper stacking device would shift up and down every set of 50 in order to accomplish the desire amount.
Final Design The shelves are attached to a rack which contains the electronics that operate the shelf rotating process. Once the printing process is completed or the current shelving bin has run out of space for more prints, the user will disconnect the information cable and move the attachable shelving bins to its final location. This design will allow for very little interaction and need of a user. It will also allow for easy transport to a third party since the shelving bins could directly be moved to this location as long as its within a reasonable distance. This design is also reasonable cheap since most of the parts can be made of cheaper materials such as plastic or aluminum. Our concept would be completely separate from the exiting systems, allowing it to be manually transported to a third party. First the shelving bins would be placed in front of the paper feed belt where the finished printed papers exit the printer. The user would then attach the information cable to the input located on the printer. This will allow for the paper count which is tracked by the printer system to relay this information to the shelving bin. After the first 50 sheets is counted and printed, a signal will be given to the shelving bin to rotate downwards allowing for a new shelve to take its place for the next 50 sheets. This process will continue until printing needs are met.
