Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tubular aluminum extruded profiles for conducting electricity, especially under alternating current, face inefficiencies in current transmission due to large diameters and insufficient cross-sectional utilization, while also being susceptible to dirt and snow deposition and wind-induced vibrations.
Innovation Solution
A semi-finished aluminum extruded profile with a unique design featuring an upper outer section with an arcuate shape to drain snow and dirt, a lower outer section that is smaller or divided to prevent deposits, and inner sections that enhance heat dissipation and stability, allowing for improved current transmission without increasing dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the diameter of the tube is increased to enable higher current intensity, then the current transmission capacity is improved, but the dimensions become unnecessarily large
Solution Approach 1:
The conductor is divided into multiple separate current-carrying elements (multiple aluminum profiles or strands) instead of a single large-diameter tube. Each element carries a portion of the total current, allowing high current transmission capacity while maintaining compact individual dimensions. The elements can be arranged in parallel or bundled configurations.
Solution Approach 2:
Instead of increasing current capacity by increasing the cross-sectional area of a single tube (two-dimensional expansion), the invention transitions to a multi-element configuration where current is distributed across multiple smaller conductors (adding a third dimension of arrangement). This allows equivalent or superior current transmission with reduced overall dimensions through optimized spatial arrangement.
2Strength
If the wall thickness of the tube is increased to provide more cross-section, then the mechanical strength is improved, but the additional cross-section is insufficiently utilized in the case of alternating voltage
Solution Approach 1:
The single thick-walled tube is segmented into multiple thinner-walled profiles or strands. Each segment provides sufficient mechanical strength for its size, and the collective arrangement of multiple segments achieves the required overall mechanical strength while providing better electrical utilization. The segmented structure allows more effective use of the conductive material for alternating current transmission.
Solution Approach 2:
The conductor is constructed as a composite system combining multiple aluminum profiles with potential reinforcement elements (such as steel cores or tension members) to achieve the required mechanical strength. This allows the aluminum portions to be optimized for electrical conductivity without excessive wall thickness, while separate reinforcement elements provide the necessary mechanical properties.
3Object-affected harmful factors
If a tubular profile is used for outdoor application, then the susceptibility to dirt or snow deposits is reduced, but wind-induced vibrations increase
Solution Approach 1:
The single tubular profile is divided into multiple smaller profiles or strands. This segmentation reduces the surface area exposed to wind forces on each individual element, thereby reducing wind-induced vibrations and flutter. The multiple smaller elements also maintain the aerodynamic advantages of tubular shapes while minimizing vibration susceptibility through their reduced dimensions.
Solution Approach 2:
The physical parameters of the conductor are changed from a single large-diameter tube to multiple smaller-diameter elements. This parameter change affects both the aerodynamic characteristics (reducing wind vibration) and the electrical characteristics (maintaining current capacity through parallel arrangement). The scale parameter is optimized to reduce vibration while the numerical parameter (number of elements) is increased to maintain current capacity.

The design enables higher current transmission capacity, reduced susceptibility to dirt and snow, improved heat dissipation, and enhanced mechanical stability, addressing the limitations of traditional tubular profiles.
Implementation Method 1
the upper outer section has an arcuate, for example semicircular, shape in a particularly advantageous manner... ensures that rainwater and, in this respect, large amounts of snow or dust are drained off to the sides
Implementation Method 2
the profile, which open at the side, enables improved heat dissipation from the inside
Implementation Method 3
This is made of aluminum alloy (including pure aluminum)... When used as a conductor, the semi-finished profile will have a specific fixed or movable installation position
