Unfortunately, these unneeded baby strollers often end up as junk as they just collect dust in the garage. In the worst case scenario, they end up in landfills; and over time, the toxins in the materials leach into the soil and groundwater, becoming severe environmental hazards. Stemming directly from the result of human activities, the environmental and health effects of landfills and hazardous waste sites can be extensively degrading.

Lifecycle Analysis

By simply solving common problems and adding different features for the baby stroller are not enough to be revolutionary and considered a breakthrough from what the market has now. In order to enhance the baby stroller’s product performance, it is imperative to thoroughly consider all steps of a product’s life cycle. By extension, this process allows a more comprehensive view of the design to create more strategic and recognized method that adheres to international standards.

Babies R Us Upton Stroller

We use Babies R Us Upton Stroller- Asphalt for our reference product when considering the Lifecycle Analysis.

Baby Stroller Process Tree

We researched on the Internet about the common materials used in baby strollers, then conducted research to determine the process, materials, and energy used in the manufacture of the material.

Okala Impact Assessment Form

Okala Impact Assessment Form

We utilized the Okala Impact Assessment Form to calculate the Babies R Us Upton Stroller impact per lifetime by disassembling parts and weighing the components in the same category. We were able to calculate the baby stroller’s impact per lifetime to be 481.36.

Goals and Strategies

IMPACT MATRIX is used to identify the major environmental impacts throughout the life cycle to understand the relative significance of environmental impacts as well as potential design opportunities.

unistrol goals and strategies

Reduce and Reuse Materials

Complex raw material extraction and material processing

Goals and Strategies

  • Disassemble parts to reuse, refurbish, and re-manufacture
  • Reduces the components

Reduce Shipping Footprints

Components need to be shipped for assembling. After the process, they will be distributed via international shipping, using a large amount of carbon footprint

Goals and Strategies

  • Combines global manufacturing and regional manufacturing
  • Reduces the components

Extend Product Life

The stroller parts were disassembled to recycle and reduce their short lifespans or they will end up in a landfill

Goals and Strategies

  • Extends product lives by reusing parts of stroller
  • Has a sharing system that allows different individuals to share strollers on a very short term basis
  • Maintains and repairs components

Unistrol Material  

Unistrol reduces the material components to lessen the amount of material or energy used in production and minimize shipping footprint for assembly.

Okala Impact Comparison

By using the “Okala Impact Assessment Form”, we were able to calculate the baby stroller’s impact per lifetime to be 481.36 per lifetime. Since 77 percent of parents with children age 4 or under own more than one stroller, I then multiplied 481.36 by 4 and got 1925.46 per lifetime. From these calculations, we were able to evaluate life cycle impact and integrate it in our goals and design strategy. From our extensive research on materials with environmental impact, Unistrol has only 71.892 per lifetime which is almost less than seven times than “Stroller- Asphalt”.
