Overhead Line Power Generator Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In overhead-line systems, the increased load on the work rope due to its diameter and weight leads to high-powered and costly devices for winding, necessitating a reduction in the load applied to the work rope.
Innovation Solution
The system incorporates multiple supports, a main rope, a work rope, a winding device, a moving device, and a power generator, where the power generator is supported by the main rope or moving device, generating electricity as it moves relative to the main rope, thereby reducing the load on the work rope by distributing the power generator's weight to the main rope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the work rope is used to support and move the device, then the device can be moved along the overhead line, but the load on the work rope increases leading to larger diameter and weight
Solution Approach 1:
The patent divides the support function into two separate components: the main rope provides primary support and suspension, while the work rope only provides auxiliary support and movement control. This segmentation allows the work rope to be lighter and shorter since it doesn't bear the full weight of the device, resolving the contradiction between enabling device movement and minimizing work rope weight.
2Strength
If the work rope diameter and weight increase to handle the load, then the load capacity improves, but the winding device requires more power and costs more
Solution Approach 1:
By segmenting the support function between main rope and work rope, the work rope's load capacity requirements are significantly reduced. The main rope bears the primary weight load, allowing the work rope to be much lighter and smaller in diameter. This directly reduces the power requirements of the winding device, as it only needs to handle the reduced load from the work rope rather than the full device weight.
Solution Approach 2:
The main rope acts as an intermediary that transfers the primary load away from the work rope. Instead of the work rope directly supporting the full weight of the device, the main rope serves as an intermediate support structure that reduces the workload on the work rope, thereby reducing winding device power requirements.
3Length of moving object
If the work rope is made longer to span greater distances, then the coverage area increases, but the weight and load on the winding device increase
Solution Approach 1:
The patent segments the support function such that the main rope provides the primary structural support for long distances, while the work rope serves only as an auxiliary component for movement control. This allows the work rope to be shorter and lighter despite the overall system spanning greater distances, as the main rope compensates for the length requirement.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the load on the work rope, minimizing the need for high-powered winding devices and lowering operational costs by allowing the work rope to be shorter and lighter, while also providing a means to generate electricity during operation.
Implementation Method 1
The power generator is supported by the main rope or the moving device and configured to move along with movement of the work rope. The power generator generates electric power by moving relative to the main rope.

AI summary
An overhead-line using system includes: a plurality of supports; a main rope supported by the supports and configured such that both ends of the main rope are fixed; a work rope movably supported by the main rope; a winding device configured to wind up the work rope; a moving device movably supported by the main rope and connected to the work rope, the moving device being movable in the air when the work rope is wound up by the winding device; and a power generator configured to move along with movement of the work rope. The power generator generates electric power by moving relative to the main rope.
