OKnet: Cost per Life = $100
WHO net: Difficult
1. Several adults required for setup
2. Requires expensive training
3. When unpacking: even trained users can't recognize the final shape
4. Users hammer nails into walls or ceiling, tie strings to the mesh fabric, attach them, then adjust tension
5. Repositioning is difficult because of the nails and strings
OKnet™: Easy to Use
1. One-person setup -- even a youngster
2. Self-erects -- eliminates training
3. When unpacking: even 1st-time users clearly recognize the final shape
4. End panels self-open, poles self-connect; a user just attaches the pole to the panels
5. Self-standing design allows for trouble-free repositioning
WHO net: Dangerous
6. Unprotected: users must tuck loose mesh fabric under the mattress or pad -- difficult from inside
7. Vulnerable: mosquitoes bite through when skin contacts the loose mesh fabric
8. No doors: users lift tucked-under mesh to get in and out
9. No doors: lifting the mesh fabric lets mosquitoes in
10. Fragile: structural failure occurs when user movements snap a string or tear the mesh fabric
OKnet™: Safe to Use
6. Protected: tensioned mesh fabric encloses, seals-in users. Secures tightly to the mattress or pad at the corners
7: Defended: stand-alone frame keeps mesh fabric tight and away from skin
8. Two ergonomic full-length doors for easy entry and exit
9. Two snap-shut doors (spring assisted) keep mosquitos out
10. Durable: flexible end panels provide structural integrity, spread tension to prevent mesh tears
WHO net: Complicated
11. Can't be moved once installed — tied to walls by strings
12. In the Field: unstable even with additional supports
13. Complex disassembly: Unhook multiple strings, fold the mesh fabric, then try to pack it
14. If not disassembled, occupies space most homes cannot spare
OKnet™: Simple to Use
11. Self-standing, only 2 lbs. — pick up and move anywhere
12. In the Field: anchors securely with no extra parts
13. Quick, 1-person disassembly: Remove and fold the pole, stack the end panels
14. Easy storage: stacks in a flat 2in disk that fits almost anywhere
WHO net: Impractical
15. Unusable if any string or the mesh fabric is damaged
16. Rigid design restricts both shape and size
17. Wastes mesh fabric — adds cost and weight
18. Mesh fabric may be repurposed for other uses
19. LLINs per life saved > 500-1,000
20. Cost per life saved: $4,500 *
OKnet™: Better Design
15. Stronger design keeps working despite wear and tear
16. Adjustable design adapts to multiple sizes
17. Cuts mesh fabric use in half, saving cost and bulk
18. Design can't be adapted beyond its intended use
19. LLINs per life saved = 100
20. Cost per life saved: = $300
When people use them...... bednets will stop malaria
BETTER DESIGN = BETTER USABILITY = BETTER PROTECTION
