# Industrial Specification: Utility Couplers

## 1. Technical Definition
Mechanical connectors that interface between tool changers/end effectors and external utility lines (air, water, electrical, data).

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-100 bar hydraulic pressure, -20°C to 120°C temperature, 0-1000 V electrical, 0-100 Mbps data**. Failure boundary: **Hydraulic: 110 bar burst pressure, Electrical: 1200 V dielectric breakdown, Thermal: 150°C polymer degradation, Mechanical: 10⁷ cycles fatigue limit**, Mechanism: **Hydraulic: Yield strength exceedance of 316L stainless steel (205 MPa), Electrical: Paschen's law breakdown at 3.3 kV/mm air gap, Thermal: Arrhenius equation polymer chain scission at 150°C, Mechanical: Paris' law crack propagation at ΔK=15 MPa√m**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Hydraulic water hammer pressure transient reaching 150 bar | 8 | O-ring extrusion through 0.1 mm clearance gap causing seal failure | Integrate 0.5 L accumulator with 90 bar precharge and 5 ms response check valve |
| Galvanic corrosion current density exceeding 0.1 μA/cm² in chloride environment | 8 | Anodic dissolution of aluminum coupler body at 0.5 mm/year rate | Apply 50 μm PTFE coating with 1.5 V cathodic protection and 0.5 mm sacrificial anode |
