The design brief that identified the problem of mine headgear is:
The structural structure above an underground mine shaft that facilitates the hoisting of machinery, persons, or supplies is known as a headframe (also called as a gallows frame, winding tower, hoist frame, pit frame, shafthead frame, headgear, headstock, or poppethead).
Mine headgear supports wheel systems that suspend winding cables that convey employees and ore up and down deep level shafts. These weird humanoid constructions have become the mining industry's defining emblem.
A miner's helmet consists of four major components:
Part 1: The hoist or winch is in a winding house. This component of the system is responsible for winding and unwinding the steel cable.
A motor and a control system are connected to the hoist.
When a steel cable unwinds from the winch, the mine cage and skips are lowered into the mine.
When the steel cable is wound up again, the mine cage and skips are elevated.
The sheave wheel is a pulley wheel that stands above the mining shaft in Part 2. The hoist rope travels over the sheave wheel and down the mine shaft.
The sheave wheel minimizes the mine cable's sliding friction.
Part 3: The head frame is the framework that holds the sheave wheel in place. When lifting the heavy mine cage, it must be robust enough to maintain the sheave wheel in place.
The head frame's left "legs" slope towards the hoist. This is due to the cable's strain dragging the entire frame in that direction. The sloping legs keep the head frame from tipping or collapsing.
Part 4: The cage and the jumps. Miners and equipment are transported up and down the mine in the cage. Skips are attached beside or beneath the cage.
Skips are used to transport ore and waste materials from mines.

A design brief, also called as a creative brief, is a program management document that identifies the scope, scale, and key aspects of your impending design project.
