Intro to ME final design project


Published on

The purpose of this experiment is to research and design an innovative bike that serves a dual purpose of a reclining chair and an off road bike. This invention is designed to provide users the ability to work or relax off the beaten track for an entire day while minimizing the amount of supplies needed.
Our design was influenced by the research done with regards to cost of production, ease of use, safety, and bicycle functionality. These considerations were made priorities so that the final product would be the most cost effective, quality product possible.

Intro to ME final design project

  2. 2. Problem To comfortably work or relax off the beaten path for an entire day requires carrying bulky, heavy equipment and tools.
  3. 3. Current Obstacles Reaching remote locations Carrying heavy supplies Assembling cumbersome equipment Purchasing multiple products and supplies
  4. 4. Solution Design a bike that satisfies the following parameters:  Capable of off-road travel  Converts into a hammock or recliner  Minimizes excess equipment required  Safe and easy to use  Viable price point for the target market  Provides the ability to work or relax
  5. 5. Design Ideas “Concept Frame Design”  Features:  Collapsible concept frame  Recliner style chair  Advantages:  Greataesthetics  Lowest risk of serious injury  Disadvantages:  Expensive to manufacture  Uncertain bike functionality
  6. 6. Design Ideas “Concept Frame Design”Figure 1a. Initial Concept Figure 1b. Initial Concept SketchSketch of the Conceptual of the Conceptual Frame Design inFrame Design in bike form chair form
  7. 7. Design Ideas “Suspended Seat Design”  Features:  Inverted bike frame with telescoping members  Hammock style seat  Advantages:  Cheaper than the Concept Frame Design  Disadvantages:  Complicated to manufacture  Diminished bike functionality  Unstable when in use
