Why It Is Feasible

1. Universal Structural Principle: The essence of mortise-and-tenon lies in its interlocking “concave-convex” physical structure, a principle independent of material. It can be implemented as long as the material’s strength and stiffness meet design requirements.

2. Superior Properties of Metal: Metals exhibit high strength, hardness, and wear resistance, enabling the creation of more precise and durable mortise-and-tenon joints compared to wood.

3. Modern Manufacturing Techniques: Advances in CNC machining, wire cutting, and 3D printing have made it relatively easy to produce complex, high-precision mortise-and-tenon structures in metal.

Challenges and Disadvantages

1. High Processing Costs: Demands expensive precision equipment and strict process control.

2. Tolerance Sensitivity: Tight tolerances complicate assembly; loose tolerances cause instability and noise. Meticulous design is essential.

3. Reduced “Flexibility”: Unlike wooden joints that absorb impact through deformation, metal joints are more rigid and may fail abruptly under extreme force.

4. Complex Design Requirements: Requires precise mechanical calculations and simulations to ensure the safety of each joint.

Conclusion

Mortise-and-tenon structures are not only applicable to metal but are also driving innovative engineering solutions. This approach transcends mere imitation of woodworking, evolving into a new connection system that leverages modern materials and technologies while adhering to traditional principles.

In scenarios demanding high precision, detachability, stress-free assembly, and aesthetic excellence, metal mortise-and-tenon joints offer a unique alternative superior to welding or bolting. They exemplify how ancient wisdom, empowered by modern technology, can unlock new possibilities.
