Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structural elements face challenges in increasing strength without adding material, maintaining mechanical stiffness, and being versatile and cost-effective, while also being easy to manufacture and recyclable.
Innovation Solution
A structural element is created by deforming sheet material to form pods that protrude from the plane with obliquely sloping walls, using a double-depth space-frame lattice structure with interconnecting diagonal braces, allowing for efficient load distribution and resistance to tensile and compressive forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the thickness of the panel is increased to improve strength and rigidity, then the mechanical strength and rigidity are improved, but the weight and material cost increase
Solution Approach 1:
The patent transforms a 2D flat sheet into a 3D structured panel by forming pods that protrude from the sheet plane. This dimensional transformation creates internal volume and structural depth without adding external thickness, allowing the panel to achieve enhanced strength and rigidity through geometric configuration rather than material quantity.
Solution Approach 2:
The panel is segmented into multiple functional components: the base sheet material and the protruding pods. This segmentation allows each component to serve a specific purpose - the base provides continuity while the pods provide structural reinforcement - enabling strength enhancement without uniformly increasing material thickness across the entire panel.
2Strength
If additional material is added to increase panel strength, then the strength and rigidity are improved, but the material cost increases
Solution Approach 1:
The invention creates structural depth in the third dimension by forming pods that protrude from the sheet plane. This allows the panel to achieve enhanced strength and rigidity through geometric configuration rather than adding more material in the traditional sense, thereby reducing material quantity requirements while maintaining or improving structural performance.
Solution Approach 2:
The patent changes the geometric parameters of the panel by forming three-dimensional pods with specific dimensions and spacing. By optimizing pod diameter, height, and distribution patterns, the invention achieves superior strength-to-material-ratio compared to flat panels, reducing the total material quantity needed for equivalent or superior structural performance.
3Strength
If complex structures such as corrugations or composites are used to increase strength, then the strength and rigidity are improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The panel structure is segmented into a simple base sheet and discrete pod elements. This segmentation maintains manufacturing simplicity because each component can be produced using standard processes, whereas integrated complex structures like corrugations require specialized tooling and multi-step forming operations.
Solution Approach 2:
The invention uses parameter changes in pod geometry (diameter, height, spacing) to achieve strength optimization without increasing structural complexity. These parametric variations can be implemented through conventional forming tools, avoiding the need for complex corrugated profiles or multi-material composite construction.
