Team Vision for Problem Definition Phase

The team plan to execute during this phase is to thoroughly understand the reason to make a motorized pediatric stander. We placed a heavy concern to understand the positives and pitfalls from previous iterations of this device. We also planned on meeting with the client, Professor Day and CP Rochester to perform a reconnaissance for details regarding room for improvement, enhanced procedures and constraints.

Along with that information, we planned on performing a domain analysis to find set benchmarks set by similar products. We also planned to create documentation to define customer and engineering requirements and identify possible risks as we progress further into the project. The team accomplished all of the planned tasks listed above. Research, client interaction and team forming were the key focuses for this phase of the project.

Project Summary

Motorized pediatric standers are devices that allow for upright maneuverability opportunities for children with certain mobility impairments. This type of stander provides support for children who may have difficulty standing on their own, in addition to bone-growth strength and physical therapy support. The device, further, allows for children to move at some degree of independence, while being remotely-controlled by a supervisor.

Ultimately, motorized pediatric standers permit freedom of mobility, in comparison to standard wheelchairs, for the child to naturally interact with fellow peers and their surrounding environment. Previous iterations of this project have attempted to design a device that meets the specified design requirements to provide a Do-It-Yourself kit, but lacked in key aspects, such as, design variability among standers and kids, ease of use for end-users, and straight line of travel. It is also key to provide better documentation of device assembly, and use-instructions for all stakeholders involved with the final product.

The main goal of this project is to develop a functional motorized stander to be operated with a specific child, while allowing various adjustments for other children and standers to be utilized. In addition, shortfalls of the previous iterations, for instance, cumbersome and variable device design, and end-user Do-It-Yourself kit cost, will be addressed. Overall, the team will improve on the existing technical issues that remain from previous stander prototypes, and work towards improving the stander to be "market-ready". The final design will include the input of both industrial design and business students to ensure appropriate design support and market engagement for the developed product.

Customer Interview Notes

January 28, 2016: Interview with Dr. Day at R.I.T.

February 4, 2016: Interview with Linda Brown at CP Rochester

We met with Dr. Day and Linda Brown to discuss about their visions for the project and questions we had for them. Dr. Day was able to enlighten us about previous projects and their strengths and weaknesses. Linda Brown gave the team a tour of the CP Rochester facility and the past two standers that were developed by previous senior design teams. Please refer to Interview Questions & Answers for the complete compilation of the questions and answers that were asked in the interviews.

Project Goals and Key Deliverables

The end deliverable for this project will be to provide a "market-ready" motorized pediatric stander, which can be fitted to accommodate various young children and commercialized stander frames. In addition, the product can be utilized as a supplement to physical therapy sessions to engage the user in a more interactive way and add a certain level of independence for the user. To accomplish this, the following will be considered:

Design Directives (ID)

Safety for this stander will be considered in all aspects of this design project.

Past Projects

Plans for next phase

The team will use the next three weeks to formulate the system designs necessary for the stander. Dissecting the stander down to its parts will allow for the team to best organize and divide its resources in order to ensure that appropriate support is divvied between tasks (week 4).

With the support of the ID team and appropriate research, the team will finalize on their best solutions from their alternatives, and begin final drafts and feasibility analysis of the chosen design (week 5).

Finally, the team will look to present their chosen concept for review (week 6) and approval in order to move into further subsystem design and analysis.
