Team 4: Structral
Structural Design
Requirements
The requirements for the structural design (the functions, objectives and constraints)
Objectives
- To design a steel or plastic enclosure
- To design a thermal insulating door.
- To design a water collection tray.
Functions
- The water collection tray is used to collect the water from the clothes when the dryer is working.
- The enclosure and the door work together to ensure that the clothes do not fall out when they are drying.
Constraints
- The size of the dryer is within 250×220×300 (mm).
- It should contain an LCD display and some navigation buttons for the user interface.
- It should have different modes of operation depending on the user's needs.
- The temperature must not be too high. Must be below the maximum heat resistance of the material.
- Consider the economic costs.
- There should not be any safety risks.
The Design
The overall shape is rectangular parallel piped, where the drum is horizontal. The final design has the following advantages:
Using automatic control device.
The drum is made of high-quality stainless steel with high temperature resistance.
The door is fitted with a glass inspection window for easier access to clothes.
Enclosure
The enclosure includes some panels, which are inlaid in different places according to different uses.
Latch
A latch is a mechanical fastener that fixes the door and front panel. Figure 1 is the closed state, figure 2 is the open state. The movable part is fixed on the door, and the fixed point is fixed on the front panel.
Door
The final design of the door is a side-hung door with a door handle. when opening, it will be more labor-saving. The round design is to conform to the shape of the drum. We added a rubber sealing ring on the back of the door to be leak-proof and hermetically sealed.
LCD and buttons & matching openings location
We arranged the corresponding positions on the front panel according to the components that need to be installed. We arranged the components that need to interact with the user above the front panel. We arranged the parts that need to interact with the user above the front panel to facilitate the user to operate.
Water collection tray
This designed tray could be pulled out like a drawer. It is placed in the lower-left corner of the front panel. The hollowed-out design in the middle allows fingers to reach in and pull it out easily.
Extra features
We added some additional features to the dryer to complete the drying of clothes.
The first is when designing the door, our extra design is to add a rubber ring on the back of the door to increase the sealing of the dryer.
The second is that we plan to use transparent materials on the front of the water collection drawer, so that in real use scenarios, users can see the actual amount of water collected in the water drawer.
