This paper focuses on how to improve the protection ability of the tablet computer itself, and develops and designs a unique one to improve the waterproof prevention ability of the three-proof tablet?

1. The original intention/explanation of the project;
(1) Strong performance, long-lasting industrial three-proof flat-panel terminal, protection grade IP67.
②Two-color injection molding process, each protruding part of the appearance is wrapped with soft rubber to protect every detail and ensure that it will not be damaged when falling.
(3) independent waterproof ring design, waterproof and reliable.
(4) the key integrated molding process, 0 gap, waterproof performance is excellent.
⑤ Edge slope design, light and thin vision, enhance grip.
⑥ Hide the bracket to facilitate standing and free hands.
⑦ Multiple data acquisition functions, support high-precision GPS positioning, involved in a variety of industries.

2. Product characteristics:
① Waterproof IP67
(2) The internal independent waterproof ring design ensures the reliability of protection.
(3) Support 6 meters high drop.
(4) The back can be crushed by a car.
⑤ Multi-module compatibility, external back clip module. The internal design of multiple modules can be adjusted according to customer needs, with higher flexibility.
⑥ Functions can be customized according to customer needs.

3. Difficulties in design technology;
①IP67 protection level is the difficulty of the whole product. Due to factors such as space, interface, keys, expansion modules, etc., the protection difficulty is increased. Protective design, disassembly, structural mode and material selection need to be considered from the appearance design stage.
(2) Difficulties in appearance design: design to the lightest and thinnest in a limited space, and stand out among many peer products.

4. Customer feedback;
The design of the three-proof flat plate has passed the IP67 protection level test of the authoritative structure. In the startup state, the natural fall body at an altitude of 3 meters falls onto the cement floor and can still be used normally. It has passed the waterproof, salt spray and vibration tests.
