It is talked about that Lego block used 'parts that can not be disassembled by hand' contrary to the principle

Lego blocks , a toy that fosters children's creativity, have always been able to 'disassemble parts by hand' so that children can make what they like. However, the newly released ' 75313 AT-AT ' has become a hot topic as it contains parts that cannot be disassembled.

The '75313 AT-AT', which includes parts that cannot be disassembled, reproduces the weapon ' AT-AT ' that appears in 'Star Wars Episode 5 / The Empire Strikes Back'. The head and legs move, and it is equipped with realistic gimmicks such as cannons, rotating cannons, bomb dropping hatches, rope connection hooks, etc.

According to the Lego block guide & database Brickset , the '75313 AT-AT' breaks the Lego block convention of 'blocks that can be disassembled to the end' so that internal parts cannot be disassembled without sharp metal tools. It is said that it has become.

The parts in question are the following frame parts included in '75313 AT-AT'. This is part of a series of techniques in Lego where you can learn how real machines work.

Introduced in 2009, this frame allows you to put the axle inside, but after putting the two, you can't take them out without tools. Brickset says this should be known to designers.

In the AT-AT Walker, an orange pin is inserted into the gray axle as shown in the figure below. Up to this point, the parts can be disassembled by hand.

After that, the green pin is inserted from the other side so as to fill the gap in the axle. Then, the '4' pin is inserted from the outside of the frame and fixed. The green pin has a gap enough to insert a knife, and you can remove the '4' axle by loosening the green pin with a knife. However, it seems impossible to disassemble it by hand. This seems to be a process to secure the orange pin, but 'honestly, I'm surprised that this went through a rigorous review of Lego,' Brickset said.

Also, when attaching the car body to the underframe, the axle is inserted into the hole, but since the axle and the hole are not the same shape, it cannot be removed without tools.

In response to Brickset's report, 'I think this goes against the core of Lego's principles. It has been thought that Lego can not only build, but also decompose and reconstruct any model. The comment has been sent.
