15. Box Wood Frame Conception Details¶

15.1. Design purpose¶

The Box_Wood_Frame design is a solid and cost effective piece of furniture that can be piled up.

_images/pile_up_of_pieces_of_furniture.png

The pile-up feature is useful for:

rearranging interior
transporting the pieces of furniture
moving accommodation
And also, maybe, building straw house
it lets make big pieces of furniture out of small pieces of material
the conception is also cut in several small problematics
the big pieces of furniture can be easily dismount, transport and remount

The frame is made out of solid wood planks. The faces can then be closed with light plywood.

A module corresponds to one or several box of the grid. We focus on the concatenation of box along the x axis. N is the number of concatenated box (along the x axis).

15.2. Construction method¶

The planks are fixed by crenel and glue.

15.3. Design proposal¶

Wood frame plank list:

horizontal plank: 20x60
vertical plank: 20x30
diagonal: 10x30 (thiner to give space for the face plywood)

15.4. Box wood frame parameters¶

A module is defined by:

The box dimension (w*d*h): 300*300*300
The number of aggregated box: N*1*1

N is the length of the module. It is a number of boxes.

15.5. Plank outline description¶

Q is the number of required planks to build one module. It can depends on N, the length of the module.

15.5.1. plank01_xz_bottom¶

Q = 2

15.5.2. plank02_xz_top¶

Q = 2

15.5.3. plank03_yz_bottom¶

Q = 2

15.5.4. plank04_yz_top¶

Q = 2

15.5.5. plank05_z_side¶

Q = 2*(3+N)

15.5.6. plank06_zx_middle¶

Q = 2*(N-1)

15.5.7. plank07_wall_diagonal¶

Q = 4*(1+3*N)

15.5.8. plank08_tobo_diagonal¶

Q = 8*N

15.5.9. hole_cover¶

Q = 8*(N+1)

The plank09_hole_cover has an aesthetic functionality.

15.6. Diagonal plank reorientation¶

The planks are positioned in the cuboid assembly with the place_plank() function. To position the diagonal planks with this function, the diagonal planks must first be rotated of 45 degrees and affected with virtual length and width corresponding to the assimilated straight plank.

15.7. Slab outline description¶

15.7.1. slab51_tobo_single¶

Q = 2 if (N==1) else 0

15.7.2. slab52_tobo_side¶

Q = 4 if (N>1) else 0

Same outline as slab51_tobo_single except that the length is:

box_width - 1.5*plank_height

15.7.3. slab53_tobo_middle¶

Q = 2*(N-2) if (N>2) else 0

Same outline as slab51_tobo_single except that the length is:

box_width - 1.0*plank_height

15.7.4. slab54_side_left_right¶

Q = 2

15.7.5. slab55_side_rear_single¶

Q = 1 if (N==1) else 0

_images/slab55_side_rear_outline.png

15.7.6. slab56_side_rear_side¶

Q = 2 if (N>1) else 0

Same outline as slab55_side_rear_single except that the length is:

box_width - 1.5*plank_v_width

15.7.7. slab57_side_rear_middle¶

Q = N-2 if (N>2) else 0

Same outline as slab55_side_rear_single except that the length is:

box_width - 1.0*plank_v_width

15.7.8. slab58_front¶

Q = 4*N
