HUMAN FACTORS ENGINEERING LAB

Ergonomics & Usability Analysis Services

Unlike standard benchmarking that focuses solely on hardware, our Ergonomics Analysis Services evaluate the exact physical interaction between human physiology and product geometry. Through high-precision Product Usability Benchmarking Engineering and pressure mapping, we eliminate operator fatigue and engineer effortless comfort.

// HUMAN FACTORS STORYBOARD

Every Comfort Complaint Starts With a Measurable Dimension.

Through rigorous Ergonomic Design Evaluation Services and comprehensive Product Ergonomics Analysis Study, we transform subjective user feedback into precise mechanical parameters.

STEP 01

Grip Diameter

Optimising handle cylindrical volume for sustained torque.

STEP 02

Finger Reach

Mapping index and thumb functional arcs to secondary triggers.

STEP 03

Control Position

Aligning tactile interfaces with natural visual and motor pathways.

STEP 04

Hand Posture

Maintaining neutral wrist angles during high-load operations.

STEP 05

Muscle Fatigue

Minimising localized pressure concentrations over extended shifts.

STEP 01 // GRIP DIAMETER BENCHMARK

Cylindrical Grip Volume Optimization

When a tool handle is too narrow or too wide, operator flexor muscles must over-contract to maintain stability. By scanning competitor products and evaluating palm contact area across 5th to 95th percentile hand sizes, we identify the exact 33.5mm – 36.0mm sweet spot for maximum torque transmission with minimal exertion.

Palmar Pressure Distribution & Vibration Dampening

The human palm houses critical nerve pathways (ulnar and median nerves). Unbuffered pressure peaks from angular product ribs cause numbness and rapid fatigue. We map contact surface area to ensure load is distributed across high-tolerance muscular pads rather than vulnerable nerve canals.

FAQ

Frequently Asked Questions

Can you perform 3D scanning on-site at our manufacturing plant?

Yes. Our engineers travel across India with portable HandySCAN 3D, optical CMMs, and laser trackers to scan parts, dies, tooling, and vehicle bodies directly on your shop floor without disassembly.

How do 3D scanning and reverse engineering differ?

3D scanning captures the raw physical surface geometry as a dense polygonal mesh (.STL). Reverse engineering takes that scan mesh and reconstructs a fully parametric, editable 3D CAD model (STEP, IGES, SolidWorks, NX) with design intent and standard geometric features.

What is a color deviation inspection map?

A color deviation map is a 3D visual comparison of the scanned physical part overlaid against the nominal CAD model. Color gradients (green = in tolerance, red = excess material, blue = undersize) immediately highlight manufacturing warpage, shrinkage, or machining errors.

Can dark, shiny, or transparent surfaces be scanned?

Yes. Our blue laser and structured light scanners handle dark and metallic surfaces directly. For highly reflective chrome or clear glass, a temporary sublimating scan spray is applied that evaporates completely without residue.

What accuracy can we expect for automotive and aerospace components?

We achieve volumetric accuracy down to 0.020 mm to 0.040 mm depending on part size and sensor setup, fully verified against VDI/VDE 2634 and ISO 10360 metrology standards.
