[YesAuto Design Decoding] Nowadays, we have higher and higher requirements for the quality of car interiors. Even with a limited budget, we are not limited to satisfying basic power, space, fuel economy requirements, and excellent interior texture. Inferiority is also an important factor in deciding to place an order. This requires manufacturers to “graze less and work more”, and at a limited cost, make the interiors of models within 100,000 yuan or about 100,000 yuan look like they have a higher price. The quality of the product, so what “small tricks” did manufacturers use to satisfy consumers? Let's take a look together.

Imagine when we enter a car, where is the first thing we see and touch in the car? The first thing we subconsciously see when the door is opened is the dashboard inside the car, and then when the door is closed, we will touch the handrails and panels on the door inner panel, so we can say the texture of the dashboard and door inner panel It first affected our judgment of the interior level in the subconscious.

Regarding the evaluation of interior design, it will definitely involve the door inner panel, instrument panel, steering wheel, seat, stop bar, center console buttons, etc., as well as materials, workmanship, color matching, lines, lighting, touch and texture, etc. All angles. Later, we will conduct a more comprehensive interpretation of the interior, and today we will only talk about how manufacturers control costs from the dimensions of the workmanship and materials of the door inner panel and the instrument panel.

The best-selling model BYD F3, which was born as the “standard” Toyota Corolla, once made BYD Company famous. Now the tens of thousands of dollars of BYD F3's interior design is no longer so old-fashioned and dull. How to do it due to cost consideration Up to this point?

But after all, models with a price of tens of thousands of dollars cannot match millions of luxury cars in terms of interior design. Because in the eyes of most of us, luxurious interiors mean more leather, delicate stitching, soft touch, more layered and three-dimensional instrument panel design, etc., because of the traditional This is the design used in luxury cars. Based on this concept, in order to eliminate the sense of cheapness, manufacturers will do their best to make some low-priced models look more like those luxury cars.

● Low-cost design one: reduce costs in places that are not easy to find

-Integrate parts and reduce production processes

We know that there are many functions on the inner panel of the door, such as window lift control, door unlocking, rearview mirror control, door handles, storage compartments, speakers and so on. Different functional components generally require multiple different molds to be processed during production, and then assembled.

More molds mean that manufacturers need more mold development costs, equipment costs, as well as more labor costs caused by assembly procedures, etc., which is undoubtedly critical for a cheaper car Profit killer. Therefore, the approach of some manufacturers is to improve the integration of interior door panels. For example, the Pentium B30 that has received more attention.

-Use more cost-effective buckles

Of course, no matter how high the integration is, it is impossible to inject all the parts of the door inner panel at one time. For example, some decorative strips, switch control panels, storage compartments, etc. need to be combined separately. Compared with ordinary plastic fusion welding methods, some manufacturers switch to buckle assembly instead, which saves the cost of welding equipment and processing.

The reduction of molds and the reduction of processing difficulty can save costs to a large extent, and save the places that our consumers can't see or find it is difficult to find. So how do you save costs where you can see it?

-The difference between touch and vision

Generally speaking, the soft leather surface of the car interior is more upscale than the hard plastic surface, but due to cost considerations, manufacturers are not allowed to cover a large area of soft skin. Of course, the soft skin mentioned here is not a genuine leather material, but a common PVC (polyvinyl chloride) leather. In order to be more cost-effective, these soft skins usually only appear in places that our human body often touches.

Although there is no extensive use of skin covering, but in order to further create a more advanced feeling, some manufacturers will cleverly inject the surface of the door inner panel to have the same texture as the PVC skin used. It is difficult to distinguish visually. The skin and non-skinned parts make people feel that the entire door inner panel is covered with soft skin.

-Toyota's simulation stitch design

When it comes to falsification, Toyota is definitely a master. In order to imitate the luxury of leather stitching, Toyota used the design of artificial stitching, with the leather texture etched on the interior parts, so that low-priced models also have a visually luxurious car atmosphere. This is reflected in its Vios, YARiS L, Corolla, Ralink and other models.

● Low-cost design 3: Plastic does not mean cheap

Plastic material has the advantages of strong plasticity, light weight, stable performance, strong corrosion resistance, etc., which makes it very suitable for automotive interior parts, and its low price makes it the preferred material for vehicle interiors. However, if the design and craftsmanship are not fully considered, they will look full of plastic and make people feel very cheap. Therefore, how to make good use of plastic materials has become the key to low-cost design.

-Reasonable use of coarse texture

Any auto parts and accessories have tolerance requirements in the eyes of engineers. Their straightness, flatness, roundness, direction tolerance, position tolerance, etc. must be guaranteed within a certain range, and the same is true for interior door panels. . When engineering parts, the smaller (stricter) tolerances such as flatness are required, the higher the engineering difficulty and production equipment requirements, and the higher the cost.

-The details are embellished with chrome decoration

Single-color plastic interiors often give people a bland and tasteless feeling, and if you add some chrome trims as an embellishment, it will often play a finishing touch. Although this will increase some costs, it is still worthwhile for the results. The exterior design of China V3 and Trumpchi GS4 also gave us a refreshing feeling, and the use of chrome trim in the interior showed some differences.

-Use shiny interiors with caution

Let’s compare the well-selling Baojun 560 with the Jingyi X5. Although the Jingyi X5 also uses chrome trim and the LCD screen is relatively larger, most people still think that the center console of the Baojun 560 is more visible. Exquisite. This is because the bright surface treatment of the Jingyi X5 interior often gives people a strong sense of plastic. From this perspective, perhaps the frosted Baojun 560 is more acceptable.

Perhaps the above-mentioned “little tricks” can “deceive” our eyes, but the dry and hard texture that the resin plastic brings to people can not be erased in any way. So for cheap cars, the interior texture must be very hard and rough? Below we introduce to you that through the use of different materials and processes, it can also save costs while also providing a good texture.

● Low-cost design 4: Replacement of interior skin

At present, the surface technology of the interior center console and door inner panel of luxury cars is generally skeleton + leather skin or skeleton + PVC slush plastic skin. Undoubtedly, the leather interior materials are the most hand-feeling, luxurious, comfortable and flexible, but they are also the most expensive.

PVC (polyvinyl chloride) slush molding skin also has excellent touch texture, soft and elastic, uniform texture and strong three-dimensional effect. Compared with ordinary PVC skin technology, its production process is more complicated, so the cost will be relatively Taller. Due to the limited thickness of the skin produced by the slush molding process, the PU (polyurethane) foam layer is generally assisted in the car interior. For example, when processing the instrument panel, the skin peeled off from the mold should be placed in a foaming mold together with the interior frame, injected with PU foam, and after foaming and curing, it becomes a slush-plastic skin foamed instrument panel.

Although the slush molding process is becoming more and more common, it is still slightly “luxury” for models with a value of less than 100,000 yuan, so most of these models still use ordinary PVC skins. In order to ensure a certain degree of flexibility, manufacturers will use ordinary PVC skin + foamed cotton + skeleton to make the interior surface.

The interior with low-cost materials and craftsmanship must not be comparable to the interior of a luxury car when we touch it with our own hands. However, considering the difference in positioning, it is very difficult for manufacturers to simulate a certain sense of luxury at a limited cost. Easy. Perhaps it is not the manufacturers themselves that can give these low-cost excellent solutions, but the ideas of the fiercely competitive auto suppliers under the requirements of the cost, specifications, and effects of interior parts stipulated by the manufacturers.

to sum up:

Low-cost interiors do not necessarily give people cheap senses. With the advancement of interior technology, manufacturers have made the interior of a 100,000 car model look a lot of luxury brought by leather interior through the design of imitation leather texture and simulation stitching. The use of PVC skin or textile fabric instead of leather covering and slush-molded skin, although the texture obtained is far less than the latter two, but it can also improve comfort to a certain extent. In addition, low-cost design can also obtain excellent interior texture through the rational use of plastic materials, such as the design of coarse-grained surfaces and frosted surfaces. Moreover, the way manufacturers reduce costs is only reflected in the undetected position of the door inner panel buckle.

Perhaps, an automobile manufacturer’s interior design skills are not simply reflected in how excellent and luxurious it can be designed, but also in whether it can create a relatively more texture for our consumers within the limit of lower cost. Interior. This can not only support manufacturers' actions to lower the price of models, but also provide more possibilities for consumers with limited budgets to buy cars.
