Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional materials (wood, steel) are used for base plates, then cost is reduced, but strength and durability under severe conditions deteriorate
Solution Approach 1:
The base plate unit employs fiber-reinforced plastic (FRP) composite material to achieve high strength and durability while maintaining cost-effectiveness. The composite structure combines resin matrix with reinforcing fibers to provide superior mechanical properties compared to traditional materials, resolving the contradiction between strength requirements and manufacturing cost.
2Reliability
If FRP is used to make base plate, then strength and durability are improved, but cost increases
Solution Approach 1:
The base plate is divided into multiple bearing parts arranged transversally at intervals, with each part comprising panels, web plates, and bottom supports. This segmentation allows for optimized material distribution, reducing overall FRP usage while maintaining durability and load-bearing capacity across the entire structure.
Solution Approach 2:
Different regions of the base plate are designed with varying thickness and structural complexity based on local load requirements. The panel thickness ranges from 3-8mm, web plate thickness from 4-7mm, and foot plate thickness from 3-7mm, optimizing material usage and cost while ensuring durability where needed.
3Strength
If base plate thickness is increased, then bearing capacity is improved, but weight increases
Solution Approach 1:
The base plate utilizes thin-walled FRP structures with panel thickness of 3-8mm and foot plate thickness of 3-7mm, achieving high bearing capacity through optimized geometric configuration rather than increased thickness. The integral structure with web plates and bottom supports provides structural efficiency, reducing weight while maintaining strength.
4Ease of manufacture
If integral structure is used, then manufacturing complexity is reduced, but material usage increases
Solution Approach 1:
The base plate unit is designed as an integral structure comprising multiple bearing parts with panels, web plates, and bottom supports that are monolithically formed from FRP composite material. This integral construction reduces manufacturing complexity by eliminating assembly operations while the segmented bearing parts optimize material distribution to reduce overall material usage.

AI summary
Provided is a base plate unit (1). The base plate unit is of an integrated structure made of fiber reinforced polymer-matrix composite materials, and comprises a base plate unit body (11) and foot plates (12). The base plate unit body comprises at least one bearing part (111), and each bearing part comprises a panel (1111), a plurality of web plates extending downwards from the bottom of the panel, and bottom supports (1114) disposed at the lower end of the web plates. The web plates comprise two side-web plates (1112) located on the two sides of the panel and a middle web plate (1113) located in the middle. The foot plates are disposed on the two outer sides of the bottom of the base plate unit body, and are formed by the bottoms of the two side-web plates on the outmost side of the base plate unit body respectively extending outwards in the horizontal direction. The width of the panel of each bearing part is 50 to 450 mm and the thickness is 3 to 8 mm. The thickness of the web plates is 4 to 7 mm. The thickness of the foot plates is 3 to 7 mm and the width is 15 to 40 mm. Through matching of all the structures in shape and size, the costs and bearing performance are optimized. Also provided is a base plate unit provided with a cavity filling member (15), which can achieve the optimization effects of costs and bearing performance as well.
