Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional crossarms in power transmission systems, whether made of wood, steel, or other materials, face issues such as deterioration, corrosion, and lack of electrical insulation, posing safety risks and maintenance challenges due to moisture absorption and animal habitation in hollow tubes.
Innovation Solution
A crossarm made from composite materials like reinforced plastic with continuous or discontinuous fibers, designed with a reinforced L-shaped geometry and a mounting base system that secures the crossarm with fastening elements, providing structural integrity and easy installation, while being lightweight and adaptable for various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wood crossarms are used, then ease of manufacture and cost-effectiveness are improved, but durability and electrical insulation are worsened due to deterioration and moisture absorption
Solution Approach 1:
The patent applies composite materials by combining fiberglass reinforcement fibers embedded in a polymer matrix to create a crossarm that achieves both durability and electrical insulation. The composite structure provides mechanical strength while maintaining non-conductive properties, resolving the contradiction between ease of manufacture and reliability.
2Strength
If steel crossarms are used, then strength and structural integrity are improved, but electrical insulation and corrosion resistance are worsened
Solution Approach 1:
The patent uses fiberglass-reinforced polymer composites to achieve the required strength while providing inherent corrosion resistance and electrical insulation. The polymer matrix protects the fiberglass reinforcement from corrosion and maintains non-conductive properties, eliminating the harmful effects associated with steel.
Solution Approach 2:
The patent employs polymer materials that are inherently resistant to corrosion and electrical degradation, effectively creating a durable component that does not require the protective coatings or maintenance that steel structures need.
3Weight of moving object
If hollow tube crossarms are used, then weight reduction and manufacturing ease are improved, but animal habitation and moisture retention are worsened
Solution Approach 1:
The patent uses fiber-reinforced polymer materials that provide structural integrity while being inherently resistant to moisture absorption and animal infiltration. The dense composite structure eliminates the hollow cavity problem while maintaining weight advantages.

AI summary
The present disclosure relates to a mounting base for a crossarm and the crossarm. The mounting base may include a front-facing fastening surface, a rear-facing surface, and an opening formed between the front-facing fastening surface and the rear-facing surface, where the opening comprises a generally reverse L-Shaped geometry that extends through an entire width of the mounting base. The crossarm may include a first section and a second section that are oriented perpendicularly to each other, where the first section and second section are composed of composite material that contains a plurality of fibers within the composite material.
