Innovation Solution
A device comprising two plates that enclose the perpendicular beam and two L-shaped clamps functioning like a vice, with a screw system to exert tightening torque and friction, allowing for the secure assembly of three beams without perforation, using materials like aluminum, steel, or carbon fiber, and optional coatings for enhanced adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional clamping devices are used to hold three beams of rectangular section, then the beams can be secured, but the device requires multiple parts and/or perforation of beams, limiting reuse and flexibility
Solution Approach 1:
The patent merges multiple clamping functions into a single integrated device. The mechanical knot combines two clamps and two plates into one unified structure that can simultaneously secure three beams (two parallel beams and one perpendicular beam) without requiring multiple separate components or perforation of the beams, thereby improving reusability and flexibility while reducing device complexity.
Solution Approach 2:
The mechanical knot device is designed with universal applicability to hold three beams of rectangular section in a specific configuration (two parallel beams and one perpendicular beam passing between them). The single device performs multiple clamping functions simultaneously, making it versatile for various construction applications without requiring beam perforation or additional parts.
2Strength
If beams are perforated to secure them, then connection strength is improved, but beam integrity and reusability are reduced
Solution Approach 1:
The mechanical knot device achieves secure connection through self-service clamping mechanisms. The two clamps with movable clips and the two plates with internal parts create friction and adhesion forces that securely hold the three beams without requiring perforation or modification of the beams themselves, thereby maintaining beam integrity and full reusability while providing sufficient connection strength.
Solution Approach 2:
The patent replaces the traditional mechanical fastening system (screws, bolts, or perforation) with a friction-based clamping system. The clamps and plates exert tightening torque on the beams, creating friction and adhesion forces that provide secure connection without damaging the beams, thus preserving their reusability and structural integrity.

Function Achieved in This Case
Enables secure and reusable assembly of three rectangular beams by applying friction and adhesion, facilitating the construction of load-bearing structures and sustainable architecture with increased rigidity and ease of dismantling.
Implementation Method 1
The plates and clips exert a tightening torque on the beams causing friction and adhesion and thus oppose the natural movement of translation.
Implementation Method 2
The plates and clips exert a tightening torque on the beams causing friction and adhesion and thus oppose the natural movement of translation.

AI summary
The invention relates to a device that can be used to secure three beams of rectangular cross section by means of clamping, whereby the device simultaneously clamps the first beam internally between two plates (3) and two other beams, orthogonal to the first, using two clamps serving as a vice. The aforementioned clamps are formed by an L-shaped portion (1) and mobile clips (2) and the assembly comprising the clamps and the plates (3) forms a H shape. The parts are held together by a system of screws (4, 5) and the plates (3) and the clips (2) exert a clamping torque on the beams, generating friction and adhesion and thereby opposing the natural translational movement.
