Concept Design
Concept design turns an idea into sketches, evaluated directions and one CAD concept in 2-4 weeks. Process, deliverables, cost ranges and real examples.
What is concept design?
Concept design is the early product development stage where an idea becomes several evaluated design directions — requirements, sketches, three to five developed concepts, a feasibility screen and CAD of the direction you select. It answers what to build and whether it can be built at your target cost, before any engineering money is spent.
- Timeline
- 2–4 weeks
- Typical cost
- $2.5k – $15k
- You leave with
- One CAD concept
- What it is
- The stage between an idea and engineering. You leave it with one justified direction, not a folder of pictures.
- What you get
- Requirements list, ideation sketches, 3–5 developed concepts, feasibility and cost screen, CAD and renders of the selected concept.
- How long it takes
- Two to four weeks for most consumer products; four to six weeks when electronics, regulation or unusual materials are involved.
- What it costs
- $2,500–$15,000 per concept round for a simple product; $15,000–$40,000 when feasibility carries real technical risk.
- Who it is for
- Inventors, startups and manufacturers who have a defined problem and need a fundable, buildable direction before committing to tooling.
- What it is not
- Not production engineering, not a patent, not a finished prototype. Those come after a concept survives review.
Concept design compared with the stages around it
| Stage | Question it answers | Main output | Typical cost |
|---|---|---|---|
| Concept design | What should we build, and can it be built? | Evaluated directions plus CAD of the selected concept | $2.5k – $15k |
| Industrial design | How should the chosen direction look and feel? | Refined form, surfacing, CMF and renders | $5k – $25k |
| Detailed design engineering | How exactly is it manufactured? | Production-intent CAD, tolerances, BOM, DFM | $10k – $60k |
| Prototyping | Does it work in the real world? | Looks-like and works-like units for testing | $1k – $20k per round |

Concept design is the stage of product development where a defined problem is turned into several possible product directions — sketches, form studies, rough CAD and basic feasibility checks — so a team can compare options and choose one before committing to engineering. It usually takes two to six weeks and costs roughly $2,500 to $15,000 per concept round.
| Question | Short answer |
| What you get | 3-6 distinct directions, sketches or form studies, one refined CAD concept, feasibility notes |
| How long | 2-6 weeks for most consumer and industrial products |
| Typical cost | $2,500-$15,000 per concept round; full concept phase $8,000-$35,000 |
| What comes next | Detailed design engineering: production CAD, tolerances, drawings, DFM |
| When to skip it | Only when the direction is already fixed and validated by a working prototype |

Concept design at LA NPDT
We run concept design as a fixed, time-boxed round for founders and product teams in Ruston, Louisiana and across the US. You bring the problem, the user and the constraints you already know. We come back with several real directions you can hold, price and argue about — not one rendering you are expected to approve.
Every round ends the same way: one chosen direction, a refined CAD concept, and a written list of the risks that have to be resolved before production tooling. That hand-off is what makes the next phase — design for manufacturing or prototype design — quotable instead of open-ended.
What you get in a concept round
- 3-6 distinct directions — genuinely different approaches, not color variants of one idea
- Sketches and form studies in 2D, plus foam or printed study models when the product is held in the hand
- One refined CAD concept of the chosen direction, modeled to real wall thickness and real component sizes
- Feasibility notes covering process choice, likely materials, and the parts that will drive unit cost
- A rough bill of materials so the target price can be sanity-checked before engineering starts
- A written risk list — what we do not know yet, and what it will take to find out
Our six-phase concept sprint
| Phase | What happens | What you receive |
| 1. Define | Kick-off call, user and use-case review, constraint capture, target cost and volume | One-page design brief you sign off on |
| 2. Explore | Broad ideation and sketching against the brief, no filtering yet | Sketch sheets covering 15-30 raw ideas |
| 3. Narrow | We score directions on cost, manufacturability and user fit | 3-6 developed directions with trade-off notes |
| 4. Study | Foam, printed or cardboard study models of the front-runners | Physical models plus photos and video |
| 5. Refine | Chosen direction taken into CAD at real proportions and wall sections | Refined CAD concept and rendered views |
| 6. Hand off | Feasibility, rough BOM and risk list written up for the engineering phase | Concept package and a quotable next-phase scope |
Concept design work from our own portfolio
These are our projects, not textbook examples. Each one started as a concept round and shipped as a product:
- Stir n Go — a sustainable drink-stirring concept taken from sketch to industrial concept model.
- UP Trap — outdoor mosquito trap concepted around an existing consumable, then engineered for injection molding.
- Perky Paws — automated pet toy where the concept phase resolved motion, safety and battery packaging together.
- MultiNix — nursing multitool concepted with clinicians, then carried into a manufacturable design.
- Kool Jack — cooling dog vest where concept work settled the material system before any tooling money was spent.
More of the same work sits in our portfolio.
Cost and timeline bands
| Product type | Typical concept round | Timeline |
| Simple molded consumer part | $2,500 - $6,000 | 2-3 weeks |
| Consumer product with a mechanism | $6,000 - $15,000 | 3-5 weeks |
| Electro-mechanical or connected device | $12,000 - $25,000 | 4-6 weeks |
| Full concept phase across a product family | $8,000 - $35,000 | 6-10 weeks |
Bands are for scoping, not quotes. Tell us the product and the volume and we will price the round exactly — start with the concept and development questionnaire or estimate on your own with the product design cost calculator.

Concept design questions, answered
- 01How long does concept design take?
Two to six weeks for most consumer and industrial products. The variable is not drawing time, it is how many decisions are still open when we start. A clear brief with a known user and a target cost lands at the short end.
- 02What does concept design cost?
Roughly $2,500 to $15,000 for a single concept round, and $8,000 to $35,000 for a full concept phase covering a product family or several use cases.
- 03Do I own the concepts?
Yes. All sketches, models, CAD and documentation transfer to you on final payment, including the directions you did not choose.
- 04Can you skip concept design and go straight to engineering?
Only when the direction is already fixed and proven by a working prototype. Skipping it with an unvalidated direction is the most common reason a tooling budget gets spent twice.
- 05What is the difference between concept design and detailed design?
Concept design decides what the product should be. Detailed design makes that decision manufacturable — production CAD, tolerances, drawings and DFM. We cover the split in concept design vs detailed design.
- 06Do you file patents from concept work?
We do not practice law, but concept output is the right input for a provisional filing, and we run a prior art search before a direction gets committed.

Concept design services: scope, deliverables and cost
What you actually receive when you hire a concept design service, phase by phase, with the ranges most projects land in.
| Stage | Deliverable | Typical duration | Cost band |
|---|---|---|---|
| Requirements & research | Requirements list, benchmark study, constraints | 3 – 7 days | $1.5k – $4k |
| Ideation | Sketch sets across several directions | 1 – 2 weeks | $2k – $6k |
| Concept development | 3 – 5 developed concepts with rationale | 1 – 2 weeks | $3k – $10k |
| Feasibility screening | Technical and cost screen, risk list | 3 – 7 days | $2k – $8k |
| Concept CAD & renders | CAD of the selected direction, visualizations | 1 – 2 weeks | $3k – $12k |
Concept design services are the first phase of the wider product development services path. Once a direction is selected, it moves into industrial design services and then into prototype design. Concept design for an SBIR or grant application follows the same path on a compressed, reviewer-facing schedule.
Concept design services: common questions
What do concept design services include?
Concept design services cover requirements definition, research and benchmarking, ideation sketches, three to five developed concept directions, feasibility screening, basic CAD of the chosen direction, and a written rationale for the selection. The output is a decision you can fund, not a mood board.
How much do concept design services cost?
A focused concept phase for a simple product typically runs $5,000 to $15,000. A complex electromechanical or regulated product runs $15,000 to $40,000 because the feasibility work carries more risk to retire.
How long does a concept design phase take?
Two to six weeks for most products. The variable is decision speed on your side, not drawing time: concept reviews that sit for a week each add more calendar than the design work itself.
What is the difference between concept design and industrial design?
Concept design decides what to build and proves it is feasible. Industrial design refines how the chosen direction looks, feels and is used. Concept design comes first and is cheaper to change; industrial design polishes a direction that has already survived feasibility.
Concept design guides
These companion guides answer the questions that come up most often before a concept phase starts: how the work runs, what it costs, what to build first, and what the industrial design stage that follows involves.
