Triangular Connection Head for Scaffolding Triple Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular scaffolding systems face challenges in efficiently coupling three standards due to the 'double wedge head coupling' geometry, which results in uneven spacings and increased material and weight requirements, limiting stable connection solutions.
Innovation Solution
A connection head device with three units arranged in a triangular configuration, where the wedge recesses of the third unit are angled at 135 degrees relative to the first and second units, allowing for a stable 'triple coupling' that maintains a consistent spacing and reduces material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If double wedge head coupling is used to connect three scaffolding standards, then connection stability is achieved, but the spacing becomes uneven and material usage increases
Solution Approach 1:
The patent combines three separate wedge head connections into a single integrated connection head device that simultaneously connects three scaffolding standards. This merging eliminates the need for multiple separate couplings, reducing material usage while maintaining connection stability through a unified structural design.
Solution Approach 2:
The connection head device performs multiple functions simultaneously: it connects three different scaffolding standards at once, provides uniform spacing control, and eliminates the need for intermediate rod tube pieces. This multi-functionality reduces the overall material requirements compared to traditional sequential coupling methods.
2Ease of manufacture
If double wedge head coupling is used with minimum length 154 mm, then connection geometry is achieved, but the crooked dimension causes construction problems
Solution Approach 1:
The connection head device employs an asymmetric triangular configuration where the three connection points are arranged with specific angular relationships (120 degrees apart). This asymmetric design eliminates the 'crooked dimension' problem by providing a balanced, symmetric appearance from multiple viewpoints, making construction easier while maintaining the required connection geometry.
Solution Approach 2:
The invention transitions from linear sequential coupling to a three-dimensional triangular arrangement. By distributing the three connection points in a planar triangular configuration rather than along a straight line, the device achieves uniform spacing in all directions and eliminates construction problems associated with crooked dimensions.
3Adaptability or versatility
If separate connection heads are used for each scaffolding element, then flexibility in connection is achieved, but device complexity and weight increase
Solution Approach 1:
The patent integrates three separate connection head functions into a single unified device. Instead of using three independent connection heads that would require separate handling and installation, the merged device provides all three connections simultaneously, reducing structural complexity while maintaining the flexibility to connect to different scaffolding elements.

AI summary
The device (20) has three connecting head units (21.1-21.3) fixedly connected with each other, and wedge openings extending perpendicular to a perforated disk slot for insertion of a connection wedge. The wedge openings for the wedge of the first and second connecting head units are formed relative to each other in an angle (47) of 90 degrees. The wedge openings for the connection wedge of the third connecting head unit forms identical large angles (48, 49) of 135 degree at the wedge openings for the wedge of the first and second connecting head units.
