1 | OSE Specification | Description | Score | Comments |
2 | 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. | Scale from 0 to 10. 10- fits well; 5 - fits poorly; 0- doesn't fit at all | |
3 | 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. | 10 - 100 years at $100 O&M cost per year. 5 - 10 years at $1000+ O&M. 0 - 10 years at $10k O&M. | |
4 | 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. | 10 - infinitely scalable. 5 - 2-10 times scalable. 0 - not scalable | |
5 | 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. | 10 - intrchangeable at every module and part. 5 - interrchangeable with low effort only at the part level. 0- not interchangeable or interchangeable with major effort only (>>1 hr) | |
6 | 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. | 10 - uses construction set parts; 5 - requires 1 hours of work time per part; 0 - requires 10 hours of work time per part | |
7 | Simplicity. | Minimal parts count. Maximum redundancy of part types. Human Scale. Designed to meet a need with minimum effort. | 10 - consists of 5 unique parts. 5 - consists of 10 unique parts; 0 - consists of 20+ unique parts per module | |
8 | Low cost. | Off-shelf parts. Minimum machining. | 10 - 50 cents/lb. 5 - $2/lb; 0 - $10+/lb | |
9 | High Performance. | Meeting or exceeding industry standards - as defined in GVCS Comparison to Industry Standards. Overbuild with Space Frames. | 10 - meets industry standards with lifetime design at 5x or greater cost savings; 5-meets standards at same cost and lifetime design; 0 - does not meet standards and does not have lifetime design | |
10 | Efficiency. | OSE efficiency is measured on global performance (based on regenerative economic development as the goal) as opposed to point performance | 10- lifetime design, lower cost, lower production time, higher performance compared to industry standards; 5- lower cost, lower production time, higher performance, but not lifetime design; 0 - same performance and no lifetime design | |
11 | Product Ecology - | Machine fit as part of a greater product ecology - on the component level, module level, and machine level. | 10 - machine can be used with other machines and built by other machines from local resources; 5 - can be used with other machines and be built by them, but from non-local resources; 0 - doesn't fit with other machines and can't be build from local resources using other machines | |
