Lumicharge: A Solution to Power Outages

12 min read

Overview

If you are a renter, I must ask you this question: How prepared are you for a power outage, if one were to occur at tonight? Sure you have a phone for flashlight, but how long will that last – 30 minutes? 1 hour? Is your powerbank charged? Your flashlight/candles are... somewhere. And you're left wondering: Is it just my house? Did the whole neighborhood lose power? What should I do with my food in the fridge? What do I do?

Maybe you have a backup generator now, but those are expensive and not always feasible for renters. From 40 interviews, I uncovered the stress, annoyance, lack of control and anxiety renters from different walks of life face when power outages occur.

Background

As part of the TO 548 Integrated Product Development course, our multidisciplinary team was challenged with a problem statement: help renters reduce disruptions or leverage any possible benefits from power outages.

As a team of 5 we each set out to have 10 interviews with renters from different phases of life in Michigan. From these interviews, we each came up with different questions like – how do working people deal with this problem and how is it different from students? how do families with kids prepare? how do people with medical conditions prepare? but one thing was common across all interviews: renters were had their routines disrupted and felt anxious and powerless during outages. So how did we help them?

Understanding the Problem Space

Problem Statement Exploration
After conducting interviews, I synthesized all 40 conversations into an affinity map, organizing insights into focus areas that would inform our How Might We statements and personas. Four critical problems emerged:

Problem #1: The uncertainty problem

People can't prioritize actions without knowing outage duration. 69% felt annoyed by lack of light, but the real issue was not knowing if this was a 10-minute blip or a 10-hour ordeal. Short outages meant minimal disruption; long ones created cascading problems with food spoilage, lighting, boredom, and lack of utility updates.

Problem #2: The generation gap

Age groups cope differently with outages. Younger users (under 26) relied on electronic devices for entertainment, while older participants used analog activities like reading. 62% immediately searched for light–the gateway to all other activities.

Problem #3: The parent stress factor

Parents prioritize child comfort over everything. Managing a crying or uneasy child during outages overwhelmed parents. 67% of parents said their first thought was whether their kids were safe and comfortable–outweighing concerns about food or boredom.

Problem #4: The renter constraint

Renters need portable, dual-purpose solutions. Rental limitations prevent permanent electrical modifications or dedicated backup systems. The solution needed daily value, not just emergency functionality.

Ideation and Concept Development

Brainstorming Solutions

I used UX processes like Brainwriting and affinity mapping to help the team evaluate ideas systematically. We developed three initial concepts:
  • Portable light - A backup lighting solution with charging capabilities to support essential devices during outages
  • Social card game using light - An activity-based approach to combat boredom
  • Soft toy with textures, light, and sound - Focused on comforting children during outages
I deployed a Qualtrics survey to assess these concepts and understand their strengths and weaknesses. The portable light concept showed high market interest, with the soft toy as a close second. The soft toy appealed to people but a setback was the testing and validity of a toy, if it helps people/if kids will like it. The card game had a mixed reception with people unsure how to get players in the dark; additionally, it can be challenging to segregate itself from the pool of other games in market.

Meet Daniel: Our Primary Persona

By concentrating on the market interest and individuals' routines, we aimed to achieve two objectives: supporting them in their current routines and mitigating boredom, enabling them to return to activities like cooking, working, socializing, and maintaining connections. With this I created Daniel, a 24 year old graduate student who frequently experiences power outages in his rented apartment.Daniel - 24 year old Livonia student who faces power outage - Persona

Reframing the Problem Statement

So based on the concept testing results and persona, we decided to focus on the portable light concept. I transformed the problem statement to focus on specific user needs and constraints that our initial research uncovered to lead ideation and design decisions.

How might we prevent the disruption of people’s routines during a power outage without needing dedicated investments?

Testing Six Concepts

Concept Cards
I developed concept cards featuring 6 concepts in total: two were our original ideas, two were idealistic and somewhat sci-fi, and two represented competitors' offerings. The purpose of including unrealistic ideas was to assess market preference and identify favorable features.

Why Our Concepts appealed to Users

Competitors were either portable OR had backup power but never both together, and most existed as desk lamps with unappealing aesthetics. Flora (33.33% projected market share) and Sunwish (19.49% projected market share) stood strong because they combined portability with backup power while fitting into home environments.

Why Ideal Concepts did not appeal to Users

Users found them needlessly power consuming in an environment where power conservation is key.

Design Evolution

From Flora to Lumios to Ilumicharge to ...

Other important insights from the concept testing survey led the baseline for the design, by determining the budget, target audience, and key features to include.
Insight IconLighting products already exist in homes. Success required emphasizing aesthetics, functionality, and unique features over pure utility.
Insight IconFrom GlowFlo: adopt design simplicity. From Sunwish: keep power bank and charging, lose the wires and weight.
Insight IconTarget audience: 22-year-old renters with (70%) willing to spend ~$109, primarily using living rooms and bedrooms.
My teammates created user scenarios placing our product in users' daily lives, while I worked on exploring different form factors. I led brainstorming sessions on ergonomics for the detachable flashlight while sketching the floor lamp's shape, materials, and structures. Later, using affinity mapping and voting, we focused on addressing 90+ problems and concerns across five key areas to refine my designs: Ergonomics, Mechanical Stability, Aesthetics, Affordability, Electrical Efficiency

Building My Electrical Knowledge from Zero

I undertook technical development of Lumicharge's electrical components – a rechargeable battery with a detachable headlight integrated into the prototype. Having no prior knowledge of electrical components beyond basics, I studied all available campus resources, consulted with acquaintances about mechanical and technical components, and used ChatGPT extensively to understand connections and requirements (and ensure nothing exploded).This self-directed learning resulted in a fully functional working prototype that successfully demonstrated at both online and physical tradeshows.

Go-to-Market Strategy

With branding complete and pricing finalized at $119.99 USD (manufacturing cost: $68.27, margin: 43%), Hadi (my teammate) & I developed a business plan focusing on Kickstarter to validate market demand:
  • Plan A (slow sales): Pitch to mission-aligned investors, increase social media presence, collaborate with influencers
  • Plan B (fast sales): Expand product line with table lamps and wall-mounted options, scale production through pre-orders, establish retail partnerships
Lastly, I developed the product website and introduction video to support the launch at the tradeshow.

Tradeshow Performance

We presented Lumicharge at a mock online and offline tradeshow where attendees had $200 USD to purchase from 5 presented products. Lumicharge emerged as the top-selling product in the online tradeshow, achieving the highest profit margin and ranking second in overall sales. However, physical tradeshow performance was weaker, which led to important insights about product positioning and scale in physical retail environments.

Reflections

Large Size = Larger Commitment

The product struggled to capture engagement during the physical tradeshow. After analysis, we identified that smaller products invite less commitment, while larger ones require more consideration regarding space and cost. The dual-purpose design positioned Lumicharge as a competitor to existing floor lamps, making it particularly attractive for those moving or setting up new spaces–but also placing it in direct competition with furniture options available outside the expo.
