Frame Designs

Goals

• durable (won't rust, rot, or become brittle)
• doesn't compromise accuracy
• low cost
• light weight
• overload limit
• protect load cells from uneven heating
• enclose electronics and conceal or protect wires.

Probably two different designs:

1. A low cost load cell mounting system for 1, 2 or 4 load cells for a mass produced consumer product.
2. A load cell mounting system that can be built from readily available materials by students using tools found in a home shop.

Designs

Many interesting and innovative designs have been suggested, built and tested. Each have advantages and disadvantages:

1. Punched and bent
2. Welded Steel Rectangular Tubing
3. Progressive die stamped and welded
4. 3D printed corner brackets/metal tubing
5. Frameless (2 rails) using strut
6. Octanorm aluminum extrusion with torx cam locks
7. Vacuum Forming: A Plastic/Aluminum Hybrid Frame
8. Ultimate Bottom Board: Utilizing a Manufactured Frame with Aluminum Undercarrage
9. Thrifty-Bee Scale: A Low-Cost All Aluminum Scale
