# Industrial Specification: Joystick Control Unit

## 1. Technical Definition
A manual input device for controlling bridge operations through joystick manipulation.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-5.0 NÂ·m torque resistance, 0-100 mm displacement per axis**. Failure boundary: **Exceeds 6.0 NÂ·m torque resistance or 120 mm displacement, or operates below -20Â°C or above 85Â°C**, Mechanism: **Plastic deformation of internal potentiometer wiper arms beyond yield strength (approximately 250 MPa for phosphor bronze), or lubricant viscosity breakdown in gimbal mechanism**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Ingress of conductive particulate matter (e.g., metal shavings &gt;50 Î¼m) into housing | 8 | Short circuit between potentiometer tracks causing erratic voltage signals (0-5V range deviation &gt;Â±0.5V) | IP67-rated sealed enclosure with conductive particle filtration at ventilation ports |
| Repeated angular deflection exceeding 30Â° at 2 Hz frequency for &gt;10â¶ cycles | 8 | Fatigue fracture of return spring (spring steel, Ïƒ_f â‰ˆ 700 MPa) causing loss of centering force | Hard-stop mechanical limiters at Â±25Â° deflection with energy-absorbing polymer dampers |
