Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional concrete underground bases are used, then load support capacity and safety are improved, but weight, installation cost, and logistical complexity increase
Solution Approach 1:
The patent changes the material parameter from concrete to steel, and changes the structural form from monolithic to modular assembled structure. This allows achieving the required load support capacity through optimized steel section dimensions and connection designs rather than relying on high concrete strength, thereby reducing overall weight while maintaining strength requirements.
Solution Approach 2:
The underground base is divided into multiple modular components including base plate, vertical members, cross members, and connection elements. These segmented components can be manufactured separately and assembled on-site, reducing the weight of individual transportable parts while maintaining the overall structural strength through standardized connection mechanisms.
2Stability of the object's composition
If conventional concrete underground bases are used, then structural stability is improved, but installation time and weather dependency increase
Solution Approach 1:
The modular components are pre-manufactured with predetermined dimensions, shapes, and connection features. Connection elements such as bolts, welds, or other fastening mechanisms are designed to assemble components quickly without requiring complex on-site construction procedures, thereby reducing installation time while maintaining structural stability through pre-engineered connection details.
Solution Approach 2:
The design incorporates adjustable and modular connection systems that allow for flexible assembly and disassembly. The structural stability is maintained through rigid connections between modules, while the modular nature enables quick installation and adaptation to different site conditions, reducing weather dependency and installation time.
3Productivity
If steel pressure-driven bases are used, then installation speed is improved, but weight and transportation complexity increase
Solution Approach 1:
The base structure is segmented into multiple modular components that can be transported separately and assembled on-site. This segmentation allows each component to be lighter and easier to transport, while the assembled structure achieves the required strength and stability. The modular design enables faster installation compared to monolithic concrete bases without requiring heavy pressure-driven installation equipment.
Solution Approach 2:
The patent changes the structural approach from monolithic steel pressure-driven bases to modular assembled bases. This parameter change allows for reduced weight in individual components while maintaining overall structural integrity through optimized connection designs, thereby reducing transportation complexity and weight requirements compared to traditional heavy steel bases.
4Reliability
If factors of safety are increased, then reliability is improved, but weight and cost increase
Solution Approach 1:
The patent changes the approach to safety by optimizing the structural design parameters rather than simply increasing material quantity. Through optimized steel section dimensions, connection designs, and modular configurations, the structure achieves required safety factors with minimal material usage, thereby maintaining reliability while reducing weight compared to conventional approaches that simply increase material quantity to achieve safety factors.

AI summary
An underground base configured for supporting an above-ground static structure that has a pair of plates each having a distal end, a proximal end, and a body portion between the distal end and the proximal end. The pair of plates are connected to each other to define a box section and a pair of flanges extending outwardly from opposing vertices of the box section. The base further has a plurality of brackets each connected to one of the plates at the proximal end, a base plate connected to the plurality of brackets, and an adjustment plate connected to the base plate via one or more adjustment fasteners. The adjustment plate is movable relative to the base plate via the one or more adjustment fasteners to adjust an orientation of the adjustment plate relative to the base plate.
