My Rhine myrhine.tech

Handheld products, resolved before they are built.

手持产品，在动手建模之前，先把样子定下来；建模之后，几何保持可改。

My Rhine is an industrial design practice for consumer products — above all handheld grooming devices. Appearance is settled with images first, so it can be approved before modelling time is spent. The model that follows is built to stay editable, with component fit and hierarchy kept explicit.

Form study of a slim, elongated capsule-shaped handheld device in matte sage green with a graphite end cap and a single small control on its long axis
Form study 01 — capsuleSage / graphite · matte soft-touch

One continuous form, one axis of control. The capsule is the starting point for the product language below — elongated, quiet, and made to be held.

Practice

做事的三个部分

Three parts of the work, in the order they happen. Nothing here is interchangeable: an image cannot replace a model, and a render cannot replace an approval.

  1. 01

    Appearance & styling 外观与风格 · 建模之前

    Before a model exists, images explore form, colour and finish — so the look can be locked and approved by whoever decides, while changing it is still cheap. This is where styling is argued and settled, not after the geometry is built.

    Yields — appearance explorations · form studies · colour & finish direction

  2. 02

    CAD & 3D reconstruction CAD 与三维重建 · 几何可改

    From orthographic reference drawings and 3D meshes, the product is reconstructed in Rhino and Grasshopper — geometrically consistent and editable, so proportions, parts and details can still move when a decision changes. Component fit and hierarchy are worked out in the model, not left to assembly.

    Yields — editable 3D models · component fit & hierarchy · orthographic references

  3. 03

    Rendering 渲染 · 模型之后

    Once the model exists, it is rendered in KeyShot — including KeyShot 2026 AI rendering — to present the model as it is: materials, finish and proportion, shown clearly for review. Rendering comes after modelling, never instead of it.

    Yields — KeyShot renders · material & finish presentation

02

Process

先定样子，再建模型

The sequence matters. Approval sits between the images and the model — that is the whole point of working this way.

  1. Step 01

    References

    Orthographic drawings and meshes are gathered and checked, so the reconstruction starts from measured intent, not a guess.

  2. Step 02

    Appearance images

    Form, colour and finish are explored in images — several directions, compared side by side.

  3. Decision

    Approve / revise

    The look is approved here. No modelling starts on an unapproved direction.

  4. Step 03

    3D model

    The approved form is modelled in Rhino / Grasshopper, kept editable, with fit and hierarchy resolved.

  5. Step 04

    KeyShot renders

    The finished model is rendered for review — a presentation of the geometry, not a substitute for it.

No image stands in for an approval.

No render stands in for a model.

Form language

产品语言：瘦长胶囊 · 哑光软触 · 单轴极简
Form study lineup of three slim capsule handheld devices in sage green, grey and off-white, showing proportion variations with a single control on each long axis
Form study 02 — proportionsSame axis · three lengths

The images on this page are form studies — appearance explorations made before modelling, not photographs of manufactured products.

  • Slim, elongated capsule

    One continuous form with rounded ends and no added bulk. Length does the work; width stays quiet in the hand.

  • Matte, soft-touch

    A finish read by the hand rather than by shine. Colour stays muted — sage, graphite, off-white — so the form carries the product.

  • Single axis, minimal

    One line runs the length of the product, and one control sits on it. Nothing competes with the grip, and nothing needs explaining.

  • Fit & hierarchy

    Caps, seams and controls are placed on the same axis, so the parts read as one assembly — and assemble as one.

Tools & references

工具与依据

My Rhine is the independent practice of an industrial designer working on consumer products — handheld grooming devices in particular.

The work is form-first and geometry-honest: decide the appearance while it is still an image, then build a model that can still change, then render what was actually built. If a project needs only one of those three parts, it can start there.

Talk about the next form.

For appearance approval, modelling and rendering enquiries — a short note about the product and where it stands is enough to start. 欢迎来信，简单说明产品和目前的阶段即可。
