Preto-Prototype Descriptions:
Below mentioned are the 4 different concepts or refinements around our chosen concept:
Preto-Prototype Descriptions:
Below mentioned are the 4 different concepts or refinements around our chosen concept:
Pretotype 1 (Cardboard Frame):
Construction: A cardboard outer frame was built to resemble the structure of our final product, with duct tape used at the hinges to replicate a spring action.
Goal: This was our first iteration in the design process, aimed primarily at assessing whether the concept would be feasible to develop further in the future.
Pretotype 2 (Cardboard Flap):
Construction: After our first iteration, we considered making cardboard flaps that would fully enclose the product. This design was easier to construct as it didn't require a sturdy frame.
Goal: Our objective was to take a frameless approach, which would save material and reduce manufacturing costs.
Feedback: Users expressed concerns about the fully enclosed design, fearing it might frighten the baby and limit breathability, which could lead to suffocation risks.
Pretotype 3 (Scale - Cloth Pretotype):
Construction: This iteration featured a mechanical model with an outer frame made of scales, using clear tape to replicate the torsional spring action. The scale-based frame was sturdier than the first iteration, and a cloth was attached to the scales to better resemble the final product.
Goal: Our goal was to create an iteration that closely mimicked our final design, allowing users to better understand what we are trying to make and how it would function.
Feedback: Users were able to clearly understand our concept and its future application. Since cloth was incorporated, there were no major concerns. The only question raised was whether the design could potentially harm the baby's hands or legs upon contact.
Prototype - Iteration 1:
Construction: In this fourth iteration, we customized a baby seat net to meet our requirements. The key feature of this iteration was detecting sudden acceleration or deceleration using an accelerometer, which then triggered the deployment of the flap, initially held in place by a servo motor.
Goal: Our goal was to create a medium-fidelity prototype with functionality similar to our final product, focusing on completing the electronics for the system.
Key takeaways - Prototyping Iteration 1
The primary goal of this prototype iteration was to gain a comprehensive understanding of how the various subsystems of our product concept work together and to ensure their successful integration. This process allowed us to focus on key components such as the sensors, actuation circuitry, spring and interlock mechanisms, and the skeletal framework of the flap. By constructing this prototype, we aimed to deepen our knowledge of how these elements interact and refine the system's overall functionality. The build serves as an essential step in verifying that all subsystems operate cohesively before moving forward with further development.
Skeletal structure: We developed a solid understanding of the skeletal structure that will support the protective material for the flap. Moving forward, we will concentrate on optimizing the size of the structure to ensure it fits a wide range of car seat sizes and shapes.
Crash detection sensors: In this iteration, we incorporated an accelerometer but realized that this sensor alone is insufficient for accurately detecting crashes. Our goal is to replicate the sensory system used in airbags, but tailored for a retrofittable flap. Therefore, we will focus on identifying more suitable sensors to achieve this functionality.
Spring and interlock mechanisms: Now that our torsional spring mechanism concept appears viable, we will move forward with constructing a robust mechanism that integrates seamlessly with the flap’s skeletal frame.
Note: We have already gathered valuable insights into the psychological perspectives of potential users regarding the safety flap concept through previous prototyping and concept illustrations. This current iteration of prototyping was focused on deepening our own understanding of the overall system, ensuring that all components and ideas are aligned. Now, with that knowledge in place, we will be moving forward towards developing the first fully realized version of the product. This next step will focus on refining the design and creating a tangible, functional prototype.
Revised KPIs:
Based on the findings of iteration 1, we updated our KPIs.
Degree of protection: The flap's degree of protection from various directions and the amount of flying debris it will endure
Child safety: The baby's safety in the car flap (Closing action injury prevention)
Material durability: This covers everything, from material strength to impact resistance. This KPI can be evaluated using a variety of tests, including those that measure strength retention, fatigue, and endurance.
Ease of use: Intuitive design and ease of installation
Compliance with standards: Compliance to certain standards that are relevant to the product. A few of them may be
CPSC (Consumer Product Safety Commission) Standards
ASTM Standards
Chemical and Material Safety Standards
Crash Testing Protocols
ISO 9001 (Quality Management Systems)
Retrospection - Current design and progress evaluation
While we’ve gained a solid understanding of our concept and the associated subsystems needed for product development, we acknowledge that we have yet to create a fully functional prototype ready for the next stage of user testing. We are aware that we’re lagging behind in the physical prototyping phase, especially in comparison to other groups. Although we achieved our goals for this iteration—mainly gaining a better grasp of the overall design and gathering feedback from users based on the current model—we recognize that we are behind schedule when looking at the bigger picture.
Our initial aim was to use this prototype iteration as a learning opportunity, and we successfully gathered as much input from users as possible for what we’ve built so far. However, we are determined to catch up and deliver a solid, working prototype by the next iteration. Moving forward, our focus will be on the following key areas:
Completing the CAD design of the product
Finalizing the material for the flap
Refining the spring and interlock mechanisms
Integrating the actuation circuit and identifying more effective sensors for crash detection
Working on the size to ensure the flap fits universally across different car seats, along with enhancing the aesthetics
Ensuring the product meets relevant safety and material standards.
While we’ve gained some useful info from this phase, we also highlight that the delay in prototyping is a critical challenge we must address. Despite the setback, we are committed to making substantial progress and delivering a high-quality prototype in the next round.
