Designing the next generation of solar lights for children living in energy poverty.

📖 Background

SolarBuddy, an Australian charity, helps children in energy poverty. They educate students and employees about energy poverty while having them build solar-powered lights. These lights are given to children globally to help them study at night.

🔥 Challenge

The lights were sometimes incorrectly assembled or damaged beyond repair. While SolarBuddy implemented quality control checks to prevent distributing faulty lights, this process became resource-intensive and financially burdensome as programs expanded.

🎯 Objective

Our objective was to identify the key issues and evaluate if a complete redesign of the light was necessary.
🛠️ Stakeholder Interviews • Product analysis

Analysing our current systems and products

I began by studying the issues faced by the Operations & Quality Control team. Through close collaboration with Operations, I documented the types and frequency of building errors they encountered. This analysis helped identify key faults in the current assembly process.

We also analysed damaged lights returned from the field after up to three years of use. This helped us evaluate how environmental conditions affected the lights.

🛠️ Field Research • Interviews • Observations

Travelling to Papua New Guinea:

To gain a deeper understanding of how children in energy poverty used our lights, I joined a distribution trip to Papua New Guinea. During my stay with a local family, I experienced firsthand the living conditions and effects of energy poverty on both parents and children. I observed how the children used the lights in their villages, homes, and schools. These direct observations revealed several potential improvements we could implement.
🛠️ Goals • Requirements

Defining the Project Goals and Users

Our quantitative and qualitative research revealed clear opportunities for improvement, leading our team to initiate a complete redesign of the original light.

The redesign process presented complex challenges, as we needed to meet multiple objectives and accommodate diverse users. The light had to be simple enough for students to build, durable enough for distribution partners to transport, and robust enough for children to use in extreme conditions.

The light needs to be simple enough to assemble thereby reducing the light’s reliance on quality control.

The light has to be modular and easy to repair, as well as compact for distributions.

🛠️ Sketching • Ideation • Collaboration

Conceptualisation

Four Autodesk employees joined me virtually before we began sketching. Together, we generated numerous concepts focusing on waterproofing, usability, versatility, user feedback, recycled plastic, form, and humanisation of the product.
🛠️ Modelling • Rapid Prototyping

Design Development:

Initial ideas focused on using snap-fits to ensure consistent assembly. However, feedback revealed that our users enjoyed the tactile experience of screwing components together. Therefore, we opted against snap-fits to maintain an engaging assembly experience.
🛠️ Prototyping • Testing • Iteration

Design Validation

Prototyping and testing formed the project's core phase. We designed, prepared, and printed hundreds of models to test various components: housing fit, button design, handle durability, lens clarity, waterproofing, and more.
🛠️ User Experience • Stakeholder Collaboration

Implementing user friendly modes

Collaborating with our engineering partner, we looked at humanising the design even more with mood indicators so the children will know when their buddies batteries have had enough sun or when they are running out of life. This in turn, would increase the batteries’ longevity. We also introduced new modes to address user needs and allow for more use cases of the light.
🛠️ Electronics • Design for Manufacture

Final Design & Outcomes

Working closely with our manufacturers, we tested pre-production prototypes and prepared the light for tooling. The new lights are now being used in SolarBuddy's programs worldwide.

🎓 Learnings

Not collaborating with our suppliers early in the process led to delays and pushed back the project launch. Speaking with our manufacturing contacts at each milestone, rather than waiting until the end of the design process, would have kept us on schedule.
