INTEGRATION & PROTOTYPES
Think beyond the individual part.
Physical envelopes, mounting, clearances, assembly, and serviceability. I coordinate specialist input and support mechanical, material, and assembly considerations for prototype integration.
Requirements · Interfaces · Trade studies
MANUFACTURING & RELIABILITY
Follow the issue to its cause.
Supplier collaboration on design refinement, manufacturing and quality coordination, and root-cause investigation of field failures and test anomalies.
Supplier collaboration · Failure analysis
TWO INDUSTRIES / CONNECTED ENGINEERING SKILLS
What I bring to product design.
Consumer-hardware integration builds on a foundation in component design, engineering release, and supplier collaboration. Gear durability research adds experience with physical testing, precision inspection, and MATLAB analysis.

A SPATIAL PUZZLE
Every piece has a place.
Rotate, flip, and fit four pieces into one board. Fill every square and try to beat the record.

TIME
Four pieces. 16 squares. Rotate and flip to fill the entire board.
★ 4 × 4 RECORD—Loading record…
Ready to make it fit?
Fill every square. No gaps. No overlaps.

Your timer starts when you press Start. Take a look at the pieces first.
ALL 16 SQUARES / FILLED
Perfect fit!
How to play & records
Click or tap a piece, then a board square. Each piece’s dotted anchor square lands where you click. R rotates clockwise; F mirrors horizontally. Use arrow keys on the board and Enter to place. Undo does not stop the timer.
The timer continues while you switch tabs. Restart begins a new attempt. A completed board is checked and timed on the server; verification includes network travel time. The fastest saved time stays until someone beats it. Ties keep the existing record.
This is a spatial puzzle inspired by fitting parts within an envelope—not a simulation of engineering clearances or a company product.

MY WORK / HONDA R&D AMERICAS
My work at Honda.
My work spanned steering-component development, engineering release, supplier collaboration, and investigation of field and test issues.
Define the part and its requirements
- Developed and released 3D CAD models, drawings, and specifications for steering-system components using CATIA V5/V6.
- Applied GD&T and design-for-manufacture and assembly practices to engineering definition.
Balance cost, weight, and performance
- Worked with suppliers on design refinements and cost, weight, and performance trade-offs.
- Collaborated with manufacturing and quality teams to address integration and production considerations.
Keep the engineering aligned
- Coordinated with global design, quality, manufacturing, and supply-chain teams to resolve integration issues and support program milestones.
- Prepared engineering documentation and status updates to communicate technical progress.
Turn failures into design corrections
- Investigated field failures and test anomalies through root-cause analysis.
- Implemented long-term design solutions to address the issues identified.

SELECTED CONTRIBUTIONS / MICROSOFT · DEC 2025–PRESENT
From functional goals to integration studies.
Make the interfaces explicit
Engineering question: What physical requirements are needed to evaluate an idea?
My contribution: I help define envelopes, clearances, mounting, and connections, and create concept geometry to support cross-functional discussion.
Work products: Mechanical concept models and organized integration requirements, including assumptions and missing specialist inputs.
Compare alternatives on a clear basis
Engineering question: What must be coordinated to make a prototype useful?
My contribution: I coordinate mechanical, material, and assembly considerations with implementation partners and keep alternatives distinguishable.
Work products: Structured comparisons of alternatives and integration considerations for prototype work.
These summaries describe my contribution at a general level, not sole ownership or a product-release claim. Internal program details and work samples are not included.

REQUIREMENTS → GEOMETRY
Give the question a shape.
I help translate functional goals into physical envelopes, placement, clearances, mounting, and interface requirements. Concept CAD gives specialists something concrete to examine together.
COMPONENT → SYSTEM
Look beyond the part.
I coordinate enclosure and component integration studies, considering structural support, assembly, manufacturability, and serviceability alongside electrical and industrial design input.
CONCEPT → PROTOTYPE
Build to answer a question.
I support prototype integration by coordinating mechanical, material, and assembly considerations with implementation partners and keeping alternatives comparable.
ONE PRODUCT → PLATFORM
Find where reuse makes sense.
I evaluate commonality through interface compatibility and integration constraints, identifying what can be shared and what must adapt to a product’s requirements.

Curious about
how things fit.
I’m Eunsung Kim, a mechanical engineer with a background in consumer hardware, automotive development, and durability research.
I enjoy the space between an individual part and the whole product: the mounting, interfaces, assembly decisions, and trade-offs that make a design work. My approach combines detailed mechanical thinking with a broader view of the system.
