Functional Decomposition

As our team approaches the system from a high level, breaking down the customer needs into functions of the pediatric stander is helpful. From this decomposition, our team can begin to propose solutions to the functional issues raised.

Benchmarking

The stander's performance and functionality can be tested in different ways to make quantifiable goals and benchmarks to ensure the final deliverable meets the customer needs.

Concept Development

In this brainstorming phase, our team suggested all possible solutions to the functionality requirements of the stander. These solutions were selected into three different conceptual designs which were compared to team P14045's design choices. Based on this information, our team decided to pursue a realistic design with the most positive impacts on the project parameters.

Systems Architecture

The pediatric stander must accept input from the users and adjust its movement accordingly. The high-level system architecture indicates which components or groups of components interface with each other to achieve the desired behavior of the stander.

Feasibility

Estimations for feasibility have been made. These are useful for identifying if the design direction is realistic and satisfies the customer needs.

Risk Assessment

As our team approaches the design, we consider all risks that could impact the motorized pediatric stander or our ability to meet the customer needs and deliver the stander. As engineers, our biggest concerns are related to the safety of the users while also ensuring that the stander we deliver meets and exceeds the expectations of the customer.
