Cases of developing add-ons and improvement products based on existing automotive supplies

When newly developing automotive parts or accessories, it is not always necessary to design every shape from scratch. For those already installed in the vehicle A method of accurately securing the shape and fastening structure of existing parts, and then adding new functions based on them.Efficient product development is possible even with this.

This case is used in automobiles The process of 3D scanning the gear cover and performing reverse engineering based on the acquired shape datais.

3D product development starting from a physical product

Automotive interior and exterior parts are rarely made of just flat surfaces and simple circular arcs. Multiple curved surfaces connect naturally, rounds are applied to the edges, and there are subtle shape variations where they intersect with surrounding parts.

Replicating these products in CAD using only vernier calipers or general manual measurements requires a significant amount of time and trial and error.

JANGSUNG HDS actual gear cover appearance Secure the entire shape data of the product through 3D scanning.and based on the scan data, we analyzed the required geometry and performed reverse engineering.

As can be seen in the photo, the overall curved shape existing on the actual product and even the detailed groove structures on the front and sides can be acquired as 3D data.

From 3D scan data to CAD geometry

Data acquired by a 3D scanner is three-dimensional shape data that records the surface of an actual product as numerous coordinates.

However, scan data alone makes it difficult to freely modify or add new structures like the CAD models used in general mechanical design.

Therefore, analyze the scan data according to the purpose of product development, and extract the necessary reference planes, cross-sections, and surface shapes, reverse engineering process of reconstructing into 3D CAD data that can be utilized for designI need this.

The model created in this way is not simply data for replicating existing products.

designing a new part that precisely meshes with the existing gear cover, or adding specific functions Reference data for developing automotive auxiliary equipment, accessories, and improvement productscan be utilized as.

Development of an accessory that fits the existing product precisely

especially when developing automotive accessories, what is important is not only the design of the new product itself How precisely it integrates with existing vehicle partsis.

By 3D scanning the actual product to secure a reference shape, you can design the contact surface and joint of a new part while taking into account the curvature and outer shape of the existing product.

For example, if you are developing a cover, mount, protector, bracket, interior accessory, or functional part to be mounted on top of an existing automobile part, you can design a new structure based on the shape of the existing part.

If necessary, designs that account for actual installation are also possible by providing regular intervals or assembly tolerances.

Physical Object → 3D Scan → Reverse Engineering → Product Development

By utilizing 3D scanning and reverse engineering, product development can be carried out in the following ways.

Acquisition of existing product → 3D scanning → Shape data cleanup → Reference shape analysis → 3D CAD reverse engineering → Design of new additional device → Prototyping and installation review

Especially in the case of automotive parts where no drawings exist or complex free-form surface products, a major advantage is that the actual product itself can be used as the basis for design.

This applies not only to the automotive field, but also to various mechanical parts, electronic product cases, industrial covers, handles, brackets, protective structures, and more. The process of developing a new product that combines with an existing productcan be equally applied to Edo.

JANGSUNG HDS 3D Scanning and Reverse Engineering Service

JANGSUNG HDS supports everything from acquiring 3D shapes of actual products and processing scan data to 3D reverse engineering and building CAD data required for product development.

Not only when you need to redesign an existing product that lacks drawings, 3D scanning and reverse engineering can also be utilized when developing new attachments or improved products by leveraging the shape of existing products.

We build 3D shape data using methods tailored to the size and purpose of the target object, ranging from small automotive parts and various products to machinery/equipment parts and large structures.

If you have an existing product but no blueprints, if accurate measurement is difficult due to complex curved surfaces, or if you need to develop a new product that fits precisely with an existing product, physical 3D scanning can be used as the starting point for product development.
