Solution Overview
Problem
Existing pole materials like wood, iron, and concrete have significant drawbacks such as insect and microbial attacks, rusting, conductivity issues, and high maintenance costs, while FRP poles are limited by high production costs and lack of modularity, leading to inefficient transportation and installation.
Innovation Solution
The development of FRP poles composed of individual hollow parts with constant cross-sections connected by annular joints, allowing for industrialized production and easy assembly by unqualified personnel using simple tools, enabling modular construction and reduced transportation costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If FRP poles are manufactured as single integrated units, then structural strength and integrity are improved, but transportation cost and installation complexity increase
Solution Approach 1:
The pole is divided into multiple modular sections that can be manufactured separately and assembled on-site. Each section maintains structural integrity through standardized connection interfaces, allowing transportation of smaller, more manageable components that reduce logistics costs while preserving overall pole strength.
Solution Approach 2:
The modular sections are designed with telescoping or nested capabilities, allowing smaller sections to be inserted within larger ones during transportation. This nesting arrangement minimizes transport volume and cost while enabling assembly of the complete full-strength pole structure at the installation location.
2Stability of the object's composition
If FRP poles are manufactured as single integrated units, then structural integrity is improved, but installation complexity and time increase
Solution Approach 1:
The pole structure is segmented into standardized modules with pre-designed connection mechanisms. This segmentation transforms the installation process from handling one large complex unit to assembling multiple standardized components, reducing installation complexity and training requirements while maintaining structural integrity through engineered joints.
Solution Approach 2:
Connection interfaces and assembly features are pre-configured during manufacturing of each modular section. This preliminary preparation of connection points, alignment features, and bonding surfaces enables unqualified personnel to assemble the pole using simple tools and basic procedures, significantly reducing installation complexity and time.
3Ease of manufacture
If modular sections are used, then transportation efficiency is improved, but connection complexity increases
Solution Approach 1:
A universal standardized connection interface is designed that can be applied to all modular sections regardless of size or position. This universal interface simplifies the connection system by providing consistent geometry, material, and assembly procedures across all joints, reducing overall connection complexity despite the increased number of connection points required for modular assembly.
Solution Approach 2:
All connection interfaces are made homogeneous through standardization of geometry, materials, and assembly methods. This homogeneity allows unqualified personnel to assemble any section using the same simple tools and procedures, minimizing the need for specialized connection mechanisms and reducing overall system complexity.
4Ease of manufacture
If traditional pole materials like wood or iron are used, then production cost is reduced, but maintenance cost and reliability worsen
Solution Approach 1:
The pole is constructed from fiber-reinforced polymer composite materials that combine the strength and durability characteristics of materials like iron and wood with enhanced resistance to environmental degradation. These composite materials provide superior reliability by resisting rust, rot, and insect damage while maintaining cost-effectiveness through efficient manufacturing processes.
