Cap-Type Cable Laying Structure for No-Height Pole Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The decline in the number of workers available for cable laying has made it difficult to maintain construction schedules using traditional methods, which are inefficient and require working at heights.
Innovation Solution
A cable laying method that involves using a cap-type structure with a hook to grip and lift cables to the tip of a utility pole, eliminating the need for workers to perform tasks at heights, with the structure being lightweight and made of transparent plastic for ease of use and visual inspection of the pole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional cable laying methods are used with workers performing tasks at heights, then cable installation can be completed, but work efficiency is low and safety risks increase due to the declining number of available workers
Solution Approach 1:
The patent introduces a cap-type structure as an intermediary device that is attached to the utility pole tip. This structure includes a grip portion that holds the cable and a cap body that covers the pole tip. The intermediary structure enables cable fixation without requiring workers to perform dangerous tasks at heights, thereby improving both productivity and operational ease.
Solution Approach 2:
The cap-type structure is designed to be self-supporting once attached to the utility pole. The grip portion automatically secures the cable through its structural design, and the cap body stabilizes itself on the pole tip. This self-service mechanism reduces the need for continuous human intervention at heights, improving work efficiency while maintaining safety.
2Ease of operation
If a cap-type structure is used to cover the utility pole tip, then cable laying becomes easier and safer, but the structure adds complexity to the installation process
Solution Approach 1:
The cap-type structure is divided into two functional segments: a grip portion for cable fixation and a cap body for pole tip coverage. This segmentation allows each component to perform its specific function efficiently while keeping the overall design relatively simple. The modular nature facilitates easier manufacturing and installation despite the added functionality.
3Difficulty of detecting and measuring
If transparent plastic material is used for the cap-type structure, then the utility pole can be visually inspected for deterioration, but the material selection is limited
Solution Approach 1:
The patent specifies using transparent plastic material for the cap body, which allows visual inspection of the utility pole through the cap. This transparency enables inspectors to detect deterioration, cracks, or other issues without removing the cap or accessing the pole tip directly. The color/transparency property is optimized for inspection purposes while maintaining structural functionality.
