Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fiber rods are arranged in a lattice structure to accommodate load paths in multiple directions, then the component can handle multiaxial loads effectively, but the manufacturing complexity and energy consumption increase
Solution Approach 1:
The fiber component is divided into discrete fiber rods that are connected at nodes to form a lattice structure. This segmentation allows each rod to be optimized for specific load directions while simplifying the overall manufacturing process by enabling modular assembly of the truss structure.
Solution Approach 2:
The invention uses composite material construction by impregnating the fiber rod framework with matrix material. This creates a hybrid structure combining the high strength-to-weight ratio of fibers with the load-distributing properties of the matrix, enabling multiaxial load accommodation without proportionally increasing manufacturing complexity.
2Weight of moving object
If fiber rods are used to create lightweight construction, then weight is reduced, but the ability to accommodate complex load paths is limited
Solution Approach 1:
The invention transitions from planar fiber arrangements to three-dimensional truss structures with nodes and connecting rods extending in multiple spatial dimensions. This dimensional expansion enables the lightweight fiber structure to accommodate complex multiaxial load paths by distributing forces through spatially distributed rod elements connected at nodes.
Solution Approach 2:
By combining lightweight fiber rods with matrix material in a composite lattice structure, the invention achieves both weight reduction and enhanced multiaxial load capacity. The fiber rods provide tensile strength while the matrix material distributes loads across the structure, enabling complex load path accommodation without significant weight penalty.
3Ease of manufacture
If traditional manufacturing methods are used for fiber components, then production is simpler, but energy consumption and manufacturing costs increase
Solution Approach 1:
The fiber rods are pre-formed into rod shapes with predetermined geometries before assembly into the final lattice structure. This preliminary preparation of components allows for more efficient manufacturing processes during final assembly, reducing overall energy consumption and simplifying the production workflow compared to forming complex structures from raw materials in a single step.
