Monty Hall Three Door Exhibit

Choose a door, let a second participant reveal a known empty alternative, and compare staying with switching across repeated trials.

REFERENCE VIEWS · IMAGE SEQUENCE

Inspect the reference.

A fifteen-second sequence of five catalogue design images. Review the overall arrangement and component details; the sequence does not demonstrate physical operation or simulated 3D movement.

This film sequences existing reference images. It is not continuous operating footage or a moving 3D simulation; final function and configuration follow the agreed project.

THE ACTIVITY & MECHANISM

Compare staying with switching in the three-door game.

Choose one of three doors, then follow the host’s reveal and decide whether to stay or switch. Under the standard rule, the host knows the prize location, always opens an unchosen empty door and always offers a switch. Staying wins one-third of the time; switching wins two-thirds. Compare repeated trials while keeping those host rules the same.

  1. 01

    Make an initial choice

    Hide the target behind one of the three doors and make an initial choice.

  2. 02

    Reveal an unchosen empty door

    Have the informed host reveal an unchosen empty door and offer the remaining choice.

  3. 03

    Record staying or switching

    Record the outcome of staying or switching over repeated trials.

Packaging & transport
Metal shipping cases or multilayer wood-panel shipping cases. Transport arrangements and costs are agreed to suit the project.
Materials & painted finish
Common material options include Q235 steel, stainless steel, aluminium alloy, PVC, acrylic, engineering plastics. The combination is selected for each configuration. Marine anti-corrosion paint with a piano-gloss automotive paint finish. Applied to painted parts.
Typical power · powered versions
Standard products: 100–500 W; oversized installations: 1,000–5,000 W. Typical ranges for powered versions. Confirm the selected model and final connected load.
Product maintenance
Inspect removable pieces, moving parts, fasteners and the visitor controls before use. Follow the supplied operating sequence and scheduled maintenance every 30 days.
Installation & training
Complimentary training is available on site or remotely, according to project needs. If installation or on-site after-sales service is not included in the product price, the customer pays the actual travel expenses incurred, unless the contract provides otherwise.
Factory acceptance & handover
Mid-production and pre-dispatch checks are provided. Factory acceptance can take place in person at the factory or through acceptance videos. Installation and operating videos, written installation and operating instructions, drawings and a spare-parts list are provided.

Warranty & repair labour
The whole-exhibit warranty period and repair labour scope and charges are agreed in the contract.
Can we discuss a prototype or sample for a custom version?

Yes. Prototype testing and sample fabrication are available for custom projects. Discuss which functions or features you need to review for your version. The scope, cost and schedule are agreed for the project.

How prototype testing & samples work
What can we discuss for our setting?

Share the learning theme, visitor group, room plan and preferred interaction. Confirm the appearance, dimensions, controls and interpretation for the version you need.

What should we confirm before ordering?

Review the final configuration, operating instructions, power and installation needs, maintenance access and supply responsibilities with the project team.

FROM CONCEPT TO TURNKEY DELIVERY
