Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional cylindrical protrusions are used in the reinforcing board, then the table board achieves sufficient mechanical strength, but the amount of material increases and the structure becomes less efficient
Solution Approach 1:
The patent applies curvature by using arc-shaped ribs instead of straight cylindrical protrusions. The arc-shaped ribs are formed by vacuum forming a reinforcing board with an array of arc-shaped ribs, where each rib has a cross-section that is an arc shape. This curved geometry provides superior structural efficiency and strength-to-weight ratio compared to conventional cylindrical protrusions, while using less material.
Solution Approach 2:
The patent changes the geometric parameters of the reinforcing structures by transitioning from cylindrical protrusions with constant cross-section to arc-shaped ribs with optimized curved profiles. The arc-shaped ribs have specific radius of curvature and thickness parameters that are optimized to achieve maximum strength with minimum material, resolving the contradiction between strength and material quantity.
2Strength
If laminated woods or solid wood panels are used for table boards, then high mechanical strength is achieved, but the weight increases and production cost increases
Solution Approach 1:
The patent uses composite materials by combining a surface board (made of wood veneer, particle board, or other materials) with a reinforcing board (made of plastic or other materials) to form a composite table board. The reinforcing board contains an array of arc-shaped ribs that provide structural strength, while the surface board provides the visible surface. This composite structure achieves high mechanical strength with reduced weight compared to solid wood panels.
Solution Approach 2:
The patent employs thin film technology by using a thin surface board (veneer or other thin materials) bonded to the reinforcing board. The surface board acts as a thin film that provides the necessary surface functionality and aesthetic appearance while contributing minimal weight, allowing the arc-shaped ribs in the reinforcing board to provide the primary structural strength.
3Strength
If laminated woods or solid wood panels are used for table boards, then high mechanical strength is achieved, but the production cost increases and mass production becomes difficult
Solution Approach 1:
The patent applies self-service by using vacuum forming technology to automatically form the reinforcing board with the array of arc-shaped ribs. The vacuum forming process allows the reinforcing board to be automatically shaped and formed in one step, eliminating the need for complex manual assembly or multiple processing steps. This enables easy mass production while maintaining high mechanical strength, as the arc-shaped ribs are formed automatically during the vacuum forming process.
4Strength
If a larger plane area is used in the reinforcing board to maintain strength after protrusions are removed, then mechanical strength is maintained, but the amount of material increases
Solution Approach 1:
The patent resolves this contradiction by using arc-shaped ribs with optimized curvature instead of removing protrusions and requiring larger plane areas. The arc-shaped geometry provides structural efficiency that allows the ribs to maintain strength with smaller cross-sectional areas, reducing material quantity while preserving mechanical strength.
Solution Approach 2:
The patent changes the geometric parameters by optimizing the arc shape, radius of curvature, and thickness of the ribs to achieve maximum structural efficiency. This parameter optimization allows the ribs to provide sufficient strength with minimal material, eliminating the need to increase the plane area of the reinforcing board.

AI summary
A structural board comprises a surface board and a bottom board. The bottom board comprises a first supporting surface and a second supporting surface, and the surface board is fixedly connected on the second supporting surface. The bottom board comprises a plurality of protruding cavities spaced apart from one another. Two end surfaces of each of the plurality of protruding cavities along a protruding direction of the plurality of protruding cavities respectively defines the first supporting surface and the second supporting surface. Each of a plurality of straight ribs is defined by two adjacent, spaced apart protruding cavities of the plurality of protruding cavities. Some of the plurality of straight ribs are connected together in an extending direction, and the plurality of straight ribs with different extending directions extend to be cross-connected to one another to form a polygonal mesh structure that defines the first supporting surface.
