1.Enclosure Design: Rugged tablets have a robust enclosure design, often made of tough materials like reinforced plastic or magnesium alloy. The design includes protective bumpers or  shock-absorbing features around the corners and edges to absorb impacts from drops.

2.Sealed Ports and Connectors: All ports, connectors, and buttons on a rugged tablet are sealed with rubber gaskets or flaps to prevent water ingress. This ensures that no water or dust can penetrate the device through these openings.

3.IP Ratings: Rugged tablets are usually certified with an Ingress Protection (IP) rating. The IP rating indicates the tablet’s ability to resist water and dust. For example, a common IP rating for rugged tablets is IP67, which means they are dust-tight and can be submerged in water up to 1 meter for a certain duration without any damage.

4.Reinforced Glass: The display of a rugged tablet is typically made of reinforced glass, such as Gorilla Glass or Dragontrail Glass. These glasses are chemically strengthened to provide higher resistance to scratches and impacts.

5.Shock-Resistant Mounting: Some rugged tablets feature additional shock-resistant mounting systems. These systems use specialized shock-absorbing materials or mechanisms to protect internal components from sudden impacts.

6.Drop Testing: Rugged tablets undergo rigorous drop testing during the manufacturing process. They are dropped from various heights onto different surfaces to ensure they can withstand accidental drops without suffering significant damage.

7.Waterproofing Measures: The internal components of rugged tablets are often coated or sealed to protect them from water damage. This can include conformal coatings on circuit boards and connectors, as well as additional sealing materials to prevent water intrusion.

By combining these design elements and technologies, rugged tablets can achieve both waterproof and drop-proof capabilities, making them suitable for use in challenging environments like construction sites, warehouses, or outdoor fieldwork.
