Human Factors & Ergonomics
The Stress Engineering Services (SES) design process is informed by real data harnessed inductively and deductively to produce concepts that both meet and generate product specifications. SES utilizes custom test fixtures, ergonometric data logging equipment and advanced computer simulation to gather the physical data that drive design requirements such as knob size, button press force and other design requirements overlooked by design firms with less technical expertise. These data are used to drive design in two ways:
- Deductively, to drive design from the physical requirements for a device to perform a given task (e.g. the torque required to open a bottle cap with specific sealing and thread pitch requirements), and
- Inductively, to drive design from the measured output of a human (e.g. the amount of torque a human can apply to a specific knob from a specific position) and to inform the requirements of a design.
By informing design with technical requirements early in the design process, SES clients save an average of 30% over the course of a project. This is because the non-technical process of the average design firm leaves the discovery of key requirements to a later stage in the product’s development. More often than not, this results in costly rework, missed deadlines and, ultimately, a compromised product that represents a mountain of patchwork “solutions” and quick fixes.
