The Engineering Marvel Behind Modular Connection Systems
The Challenge: Creating Flexibility Without Compromise
Traditional furniture joining methods—glues, screws, or simple friction fits—fail in modular applications where:
- Frequent reconfiguration is expected
- Dynamic loads shift across connection points
- Aesthetics must remain seamless
- Long-term durability is non-negotiable
Industry Failure Points:
- Lateral Creep: Modules gradually separating under load
- Point Loading: Stress concentration at connection points
- Wear Degradation: Mechanisms failing after 10-20 reconfigurations
- Visual Disruption: Visible gaps or misalignment
The KCK.CASA Solution: Multi-Axis Locking Technology
Our patented connection system addresses these challenges through a three-dimensional approach:
1. The Vertical Lock: Gravity-Assisted Engagement
Component: Precision-cast zinc alloy receivers
Angle: 7-degree downward taper
Engagement: Self-aligning as modules are pushed together
Lock Force: 15kg vertical retention per connection point
Purpose: Prevents upward separation during use
2. The Horizontal Lock: Lateral Stability Mechanism
Component: Spring-loaded stainless steel pins
Deployment: Automatically extends upon vertical engagement
Pressure: 8kg lateral force per pin
Redundancy: Dual pins per connection (primary + backup)
Purpose: Eliminates side-to-side movement
3. The Shear Plane Lock: Diagonal Load Management
Innovation: Interlocking dovetail channels
Material: Glass-reinforced nylon composite
Engagement Depth: 42mm
Shear Strength: 220kg per connection
Purpose: Distributes diagonal forces across entire interface
