Ultimate Guide to Rear View Light Prototypes
Automotive design is likely one of the most tasking processes in the modern industry. New models keep rolling out annually owing to a shortened development time. This is often in a bid to meet prevailing market demands. Prototypes play a critical role in verifying different stages of the model development. Vehicle lamps often serve to tell other drivers or road users what the vehicle is likely to do next. They also light paths at night thereby promoting road safety. The rear-view lights essentially play the first role while the front lamps play the second role. Therefore, any driver must be able to rely on the rear-view lights to play their part in conveying the intended message. We can only verify rear-view light through the creation of their prototypes.
Here Further Insight Into Rearview Light Prototypes
The Rear Lighting System
We can thank the early 20th century for coming up with rear lights owing to an increase in the number of automobiles. It was too early for LED lights but in their stead were oil lamps. Light lamps normally do not have any brake or turn signals. Modern rear view lights have a highly complex system. This is quite crucial to the car’s design and overall performance.
Several prototypes often arise during the design and pre-production stages of production. They usually play a vital role in verifying the final product. We first verify the product’s function or image during the initial stages of product creation. This step thus entails creating a prototype that partially resembles the final product. In the case of a rearview light prototype, it is likely to look like a couple of wires that we connect to LED lights. We usually can switch them on the needed order of function. In the second phase, we proceed to include a lens in the lamp prototype. This will represent the rearview light enclosure or how it will look in the vehicle. We only need one or two products in this second phase. The third and final phase is the engineering evaluation. This is the stage where we assess the lamp’s brightness and functionality. Our experts are also likely to carry out other basic functional tests.
Validating Rear View Light Design Prototypes
Upon completion of the initial functionality, we can now begin evaluating the design. This stage serves to optimize the product’s geometry. In addition, we get to check the parts assembly for the first time. Usually, the first assembly encounters a lot of problems and thus needs a couple of corrections. Once we identify the errors, we can correct the design. Afterward, we must remanufacture the rearview light prototype to assess its design again. This is since there may be other problems that arise after making the initial corrections. Since it is an iterative process, we only make about 20 prototypes at this stage.
Results of the design validation tests encompass both environmental and cosmetic values. Moreover, we get to carry out strength tests. It involves throwing hard objects into the lens to see if they can withstand the impact. It is also the stage where we can alter some of the materials to meet any unique client needs.
Production Validation Rear View Light Prototypes
This stage often takes place after developing the manufacturing process. It is our first try at creating the final product and thus resembles its actual mass production. We thus must create the needed expensive tooling before we can proceed. This step may be a bit confusing considering we are not in the mass production stage. Well, to answer this, you must grasp that the production validation stage serves to optimize the entire creation process. We usually do not change the design unless a crucial error comes up. This is, however, unlikely as the previous stage is likely to play its part before we approve for manufacturability. By the end of this stage, we are likely to come up with 1000 rearview light products.
What Prototyping Methods Do We Use to Create Rear Lamps?
We use different methods at different stages of rearview light prototype creation. For instance, in the first stage, we are likely to come up with many changes since we lack a definite design. We thus have to use a method that allows us to remanufacture the product as quickly as possible. This is the ideal stage for using additive modes of manufacturing. It allows us to create complex free-form parts without a lot of pre-production preps. At Creatingway, we use SLA 3D printing that follows a CAD model of the part.
The second stage needs several parts and is thus not ideal for 3D printing. Since we make automotive rearview light prototypes from clear plastic, we end up using urethane casting molds. It is relatively faster and cheaper than injection molds. It is also perfect for low-volume part production.
The third stage involves product validation during which we test for mass production. The ideal prototyping process for this stage is injection molding. It entails the use of expensive steel injection molds. For us to achieve top-notch transparency, we different post finishing processes like grinding and polishing.
