Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional one-piece pole structures are used, then manufacturing and structural integrity are simplified, but height, strength, and other properties are fixed and inflexible
Solution Approach 1:
The pole is divided into multiple modular sections that can be assembled together. Each module can be independently manufactured with specific structural properties, allowing the overall pole to be customized by selecting and combining different modules. This segmentation enables flexible configuration of height, strength, and other properties while maintaining manufacturing simplicity through standardized module production.
2Ease of operation
If multi-sectional poles are divided into sections for transportation, then ease of transport and field erection is improved, but issues of height, strength, stiffness, and durability are not adequately addressed
Solution Approach 1:
Different pole sections are designed with locally optimized properties. Each module can be manufactured with specific structural characteristics tailored to its position and function in the overall pole structure. This allows the pole to achieve desired height, strength, stiffness, and durability through selective combination of modules with different local qualities, while maintaining ease of transport and assembly.
3Adaptability or versatility
If poles are made from composite materials with different structural properties, then customization of structural properties is enabled, but manufacturing complexity increases
Solution Approach 1:
The invention utilizes composite materials where structural properties such as strength, stiffness, and durability can be adjusted by changing material parameters like fiber type, resin composition, and layer configuration. This allows standard manufacturing processes to produce modules with varying structural properties by simply adjusting material parameters rather than changing the manufacturing process itself, thus enabling customization without proportionally increasing manufacturing complexity.

AI summary
A method of modular pole construction an elongate modular pole structure is disclosed. A first step of the method involves providing hollow tapered pole section modules, each module having a first open end and an opposed second open end. A cross-section of the second end is less than a cross-section of the first end. The modules are stacked to form an elongated modular pole structure of a selected length by mating the second end of a first module with the first end of a second module. The first and second modules may have different structural properties, such that poles having desired structural properties can be constructed by selectively combining modules having differing structural properties.
