Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connecting apparatuses for grooved angular beams are limited in extending their length longitudinally, often requiring welding or side connections, which are inefficient and not suitable for all cross-sectional structures.
Innovation Solution
A connecting apparatus comprising upper and lower members with inclined surfaces and pressure units that screw together, featuring a pressure rod to be pushed outward and contact the inner walls of the grooves, allowing for linear extension without welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional connecting apparatuses are used for grooved angular beams, then side connections or vertical connections can be achieved, but longitudinal extension is not possible without welding
Solution Approach 1:
The connecting apparatus is divided into upper and lower members that can be separately installed into grooves on opposite sides of the angular beam. This segmentation allows the connection to be made through the beam rather than requiring welding, enabling longitudinal extension while maintaining ease of manufacture through modular assembly
Solution Approach 2:
The connecting apparatus acts as an intermediary element that bridges two angular beams in the longitudinal direction. By installing the upper and lower members into grooves on opposite sides of the beam, the apparatus mediates the connection without requiring direct welding between beams, thus enabling longitudinal extension while simplifying the manufacturing process
2Productivity
If welding is used for longitudinal extension, then connection strength is achieved, but the process is time-consuming and requires special equipment
Solution Approach 1:
The invention replaces the welding process (thermal-chemical system) with a mechanical fastening system. The upper and lower members are installed into grooves and secured through mechanical means, eliminating the need for welding equipment and operators. This substitution dramatically increases productivity while the mechanical interlocking design maintains sufficient connection strength for structural applications
3Length of moving object
If binding members with locking devices are used, then longitudinal connection is possible, but the device structure becomes complex
Solution Approach 1:
The invention extracts the essential function of longitudinal connection from complex locking devices. By utilizing grooves already present on the angular beams and installing simple upper and lower members that fit into these grooves, the design achieves longitudinal connection without requiring additional locking mechanisms, thereby reducing device complexity while maintaining the desired functionality

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient linear or longitudinal connection and extension of grooved angular beams, overcoming the limitations of conventional methods by providing a secure, non-welding solution for various cross-sectional structures.
Implementation Method 1
a plurality of pressure units for tightly coupling the upper and lower members by coupling the first and second pressing holes of the upper and lower members in a screw engagement manner
Implementation Method 2
at least one pressure rod in which the first and second inclined surfaces of the upper and lower members are arranged to face each other to be placed in a space 'a' formed between the first and second inclined surfaces so that the upper and lower members are in close contact with each other and the space 'a' is gradually narrowed and the at least one pressure rod is pushed outward

AI summary
Provided is an angular beam connecting apparatus. Angular beams are various types of angular beams with at least one groove that includes inner walls formed on both sides of the groove. The connecting apparatus assembled in the at least one groove of the respective angular beams includes: an upper member having at least one first pressing hole formed therein and at least one first inclined surface formed therein; a lower member a second pressing hole formed therein in correspondence to the first pressing hole and a second inclined surface formed therein while facing the first inclined surface; pressure units that are screwed through the first and second pressing holes of the upper and lower members; at least one pressure rod located in the space “a” formed between the first and second inclined surfaces by placing the first and second inclined surfaces of the upper and lower members to face each other, wherein the pressure units of the connecting member penetrate the first and second pressing holes to have the upper and lower members closely contact each other, and the at least one pressure rod located in the space “a” between the first and second inclined surfaces is pushed outward to fix two angular beams and to extend the length of the structure formed by the two angular beams.
