中间不会转的方向盘，反人类设计中的巧妙设计

Summary

This video explores the unconventional design of a steering wheel where the outer rim turns while the center remains stationary, allowing for a hidden output shaft. The design ensures that an airbag deploys in a preset optimal position for maximum protection. A clever mechanism allows wires to pass through without obstruction. The video also reveals the modular design of the airbag and control buttons, emphasizing safety and ingenuity. The presenter refrains from dangerous demonstrations to protect younger viewers.

Takeaways

• 🔄 The steering wheel in question rotates on the outside, but not in the middle, creating a unique design challenge.
• 🔧 A screwdriver can be inserted into a hole in the lower part of the steering wheel to unlock it, revealing two wire groups—one for the airbag and one for the buttons and lights.
• 🛡️ The design aims to keep the airbag in a pre-set optimal position, protecting the head, chest, and even the abdomen during an accident.
• 🌀 The internal gear system is designed to move a secondary driven wheel, allowing space for wires without them getting tangled or obstructed.
• 🔍 The main output of the steering wheel and the inner mechanism do not rotate at a 1:1 ratio, meaning there is a discrepancy in rotation between the two parts.
• 🛠️ Although the design is unconventional, there are aspects that are considered clever and potentially useful for manufacturers, like modular parts for the lights and buttons.
• 💥 The airbag module is a single-use, heart-shaped unit that offers extended protection to the chest and abdomen.
• ⚠️ While it would be visually engaging to trigger the airbag for demonstration, the presenter refrains from doing so due to safety concerns, particularly for younger viewers.
• 🚗 The unusual design is meant to work despite not being perfectly centered, which is not noticeable during regular operation.
• 💨 The back of the airbag module has a small exhaust hole, which appeared to leak, suggesting there may be some flaws in the design.

Q & A

What is the primary issue with the design of the steering wheel described in the script?

The main issue is that the outer part of the steering wheel rotates, while the middle part does not, which raises questions about how the wires are routed through the non-rotating center without being obstructed.

Why was the steering wheel designed this way?

The design ensures that when the airbag deploys, it remains in a pre-set optimal position to protect the head, chest, and even the abdomen, providing maximum safety.

What is the purpose of the small hole in the steering wheel?

The small hole allows a flathead screwdriver to be inserted, which helps to release the lock mechanism holding the steering wheel in place, enabling easy disassembly.

How does the wire pass through the steering wheel if the center does not rotate?

The wire passes through a clever design where the internal gears connect to a driven wheel in the middle. This creates a gap, allowing the wire to pass without being obstructed.

What are the two main groups of wires inside the steering wheel?

One group is for the airbag, and the other group connects to the front buttons and lights on the steering wheel.

What are the two major issues the script mentions about this design?

The first issue is that the small hole is not perfectly centered, and the second is that the main steering wheel's output and the middle gear do not rotate in a 1:1 ratio.

How does the airbag module in the steering wheel work?

The airbag module is modular, with the outer circle containing lights and buttons, while the inner part contains the airbag, which is a one-time-use module made of rubber and a central core.

Why does the speaker in the video refrain from demonstrating the airbag deployment?

The speaker refrains from demonstrating the airbag deployment to avoid encouraging dangerous behavior among young viewers, as many children follow his videos.

What shape does the airbag take when deployed, and what parts of the body does it aim to protect?

The airbag takes a heart-like shape, with the lower part being longer. This design aims to protect the chest and abdomen in addition to the head.

Why is the steering wheel design considered 'anti-human' according to the speaker?

The design is considered 'anti-human' because it deviates from traditional designs and introduces complexity, like the non-rotating center, which seems counterintuitive but has its own functional reasoning.
