# Industrial Specification: Furniture Hinge

## 1. Technical Definition
Mechanical joint enabling door/cabinet opening and closing

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-120 N·m torque, 0-180° angular displacement, -20°C to 80°C ambient temperature**. Failure boundary: **Shear stress exceeding 250 MPa in hinge pin, angular deflection beyond 185° causing permanent deformation, contact pressure exceeding 1.5 GPa at bearing surfaces**, Mechanism: **Fatigue failure due to cyclic bending stress exceeding endurance limit of 150 MPa in steel components, fretting wear at contact interfaces with relative motion amplitude &gt;50 μm, stress corrosion cracking in zinc-plated surfaces at chloride concentrations &gt;100 ppm**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Cyclic loading at 15-25 Hz resonance frequency matching hinge natural frequency | 8 | Accelerated fatigue crack propagation in hinge knuckle at stress intensity factor ΔK &gt; 20 MPa√m | Design damping inserts with loss factor η &gt; 0.1, implement stress-relief radii &gt;2 mm at stress concentrators, specify shot peening to induce compressive residual stress &gt;400 MPa |
| Galvanic corrosion between dissimilar metals (steel hinge vs aluminum frame) with potential difference &gt;0.25 V | 8 | Corrosion rate exceeding 0.5 mm/year leading to joint loosening and misalignment &gt;3 mm | Apply dielectric isolation coatings with impedance &gt;10⁶ Ω·cm, specify cathodic protection with zinc sacrificial anodes, implement crevice-free design with minimum gap &gt;0.5 mm |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in these furniture hinges?
**A**: Our hinges are constructed from premium materials including cold-rolled steel, zinc alloy, stainless steel, and feature durable nylon bushings for smooth operation and longevity.

### Q: How does the soft-close feature work?
**A**: The soft-close feature utilizes a damping cylinder that gently slows down the door or cabinet during the final closing phase, preventing slamming and ensuring quiet, controlled operation.

### Q: What adjustments are possible with these hinges?
**A**: These hinges offer overlay adjustment for precise door alignment and include adjustment screws for fine-tuning the fit. The mounting plate design allows for easy installation and customization.

## 6. Manufacturing Compliance
- ISO 9001:2015 - QUALITY MANAGEMENT SYSTEMS
