Handheld
Products defined by in-hand use, direct grip, reach, balance, pointing, and control while physically supported by one or two hands during normal operation.
Catalog branch
Form factors are one of the clearest ways to narrow a product because they answer a practical physical question: what posture does the product take in ordinary use, and how does that posture shape its structure, handling, and relationship to the user or surrounding environment? The form-factor branch matters because many products become much easier to classify once their physical use mode is stated plainly. A product may belong to a consumer or industrial category, fit a device or instrument type, and still not make much practical sense until someone says that it is handheld, bench-top, wearable, or panel-mounted.
Form-factor pages are especially useful because they cut across broad categories and product types. A handheld product may be medical, industrial, consumer, or laboratory-oriented. A bench-top product can still be a device, instrument, or even part of a modular family. A wearable product may belong to personal-use, care-related, or safety-related contexts. Panel-mounted products can sit inside controlled technical setups and still differ substantially by category, type, and application. The form-factor branch does not replace those other truths. It captures the physical posture that makes many of them easier to understand.
The current form-factor paths are: Handheld, Bench-top, Wearable, and Panel Mount. These are not decorative labels. They describe durable physical patterns that strongly influence how products are designed, carried, positioned, mounted, read, operated, and integrated into real environments. By giving those physical patterns a dedicated branch, the catalog becomes much more usable for people who think with their hands, workflows, and working surfaces rather than with abstract product words alone.
These routes define the first major physical-posture routes in the catalog. Each one captures a recurring way products relate to users, surfaces, or built environments.
Products defined by in-hand use, direct grip, reach, balance, pointing, and control while physically supported by one or two hands during normal operation.
Products defined by stable use on counters, work surfaces, stations, benches, or tables where placement, access, and visibility shape ordinary use.
Products defined by body retention, body contact, personal movement, fit, and ongoing or repeated use while worn on or against the body.
Products defined by fixed integration into a larger surface, panel, enclosure, console, or equipment face where access and visibility are structured by mounting.
Form factors are most useful when the physical use posture feels like the strongest unresolved truth about the product after a broad category, family, or type has already been recognized.
If the clearest thing about a concept is how it is held, worn, placed, or mounted, the form-factor branch often gives a better next step than broad category or object type alone.
Many concepts sit between several product labels until someone identifies whether the product belongs in the hand, on a body, on a work surface, or in a mounted control plane.
Once the form factor is clear, the next step is often into Applications, Environments, Features, or related product pages that explain what the object does and where it belongs.
Visitors often know the physical posture of a product before they know its perfect application or feature route. This table gives them a practical first step.
Form factors matter because physical posture changes how a product is interpreted, designed, and compared. A product that is worn is not just a small product. A product that is bench-top is not just a portable product placed on a table. A product that is panel-mounted is not simply a device with a flat face. These physical patterns create recurring constraints and expectations that strongly affect user interaction, enclosure decisions, visibility, mounting logic, stability, and maintenance. Without a form-factor branch, a taxonomy can become too abstract and fail to reflect the physical realities that product teams care about every day.
The form-factor branch brings those realities into the structure directly. It lets visitors classify products in a way that respects posture, placement, and use orientation instead of treating them as small secondary notes. That makes the catalog more honest and more practical for people who design, build, source, or compare real products.
Form Factors sits naturally between object identity and broader context. A visitor may arrive here after clarifying a product type in Types or recognizing a broader pattern in Families. Once the physical posture becomes clear, they can move into Applications, Environments, and Features to refine what the product does, where it belongs, and what recurring traits matter. They can also move outward into Products for canonical product pages, Collections for curated groupings, or Library for longer explanation and comparisons.
That relationship keeps the branch useful instead of isolated. Form factors do not compete with the rest of the taxonomy. They make the physical side of the product legible so the rest of the taxonomy can work more effectively.
