Introduction

To assess the technological design features of OSE Specifications, these are the most important:

  1. Designed as a Product Ecology - at the component, module, and machine level. This means any single machine is being design with consideration of fitting in the overall set, not as a single machine. The intent here is that we are testing the feasibility of the entire package being managed (capable of being built from scrap steel in 50 days with 4 skilled people and 12 apprentices and repaired/maintained at no more than 300 hours per year). This is a serious quantitative milestone that will be developed as the set grows.
  2. Lifetime Design. Achieved by: bolt-together, Space Frame construction; modularity - allows new functions to come from machine, extending range of service; simplicity, transparency, and serviceability - user is in control and user can take responsibility for maintaining the machine in good shape; scalability - allows machine to grow/shrink with needs.
  3. Design for Scalability. Intensive and Extensive Scalability. Includes stackability via easy interface design. Machines should be designed to allow infinite scalability. Ex. Power cube can be built using the same structural frame in sizes from 5 hp to 200 hp, and these can be stacked in parallel or siries.
  4. Modular Design. Involves clear interface design. Quick-coupled hydraulics and bolt-together space frames facilitate this. Modularity can occur on the component level as well, with the Stock Tubing and Stock Pivot Plates. Same PTO motor drives Open Source Car and agricultural implements.
  5. Design for Fabrication. Design for minimal fabrication requirements. Design for common parts. Design for production of multiple, stock, identical components - like Legos and erector set.
  6. Simplicity. Minimal parts count. Maximum redundancy of part types.
  7. Low cost. Off-shelf parts. Minimum machining.
  8. Meeting or exceeding industry standards. Overbuild with Space Frames.
  9. Machine fit as part of a greater product ecology - on the component level, module level, and

The development process itself follows:

  1. Test-Driven Design
  2. Modular Design
  3. Interface Design (Contract-First Manufacturing)

Each of the above will be rated from 1-10 and the result summed to get an overall % score of the maximum 140 points.
