Resin Structure with Oriented Fibers for Pattern Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resin structures with fibers do not effectively utilize fibers to create a sense of depth in patterns visible from the side, lacking design differentiation and aerodynamic performance.
Innovation Solution
A resin structure with a first pattern portion and a second pattern portion, both formed from fibers oriented in different directions and with varying fiber widths, where the second portion's fibers are visible through the first portion, creating a sense of depth and enhanced stiffness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fibers are used in resin structures, then strength and stiffness are improved, but the ability to create three-dimensional depth in patterns is insufficient
Solution Approach 1:
The patent applies local quality by using fibers with different orientations and widths in different regions of the resin structure. The first pattern portion uses fibers oriented in a first direction with a first fiber width, while the second pattern portion uses fibers oriented in a second direction with a second fiber width. This creates locally differentiated properties that enable both stiffness and three-dimensional depth effects in different areas of the same structure.
Solution Approach 2:
The patent introduces another dimension by utilizing fiber orientation and width variations to create depth perception in two-dimensional patterns. By varying the fiber orientation direction and fiber width across different pattern portions, the invention transforms flat resin structures into those with perceived three-dimensional depth, allowing fibers to structure patterns as seen from the side facing the characteristic design surface.
2Shape
If fiber orientation is varied to create pattern depth, then visual design is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-orienting fibers in specific directions and pre-determining fiber widths during the manufacturing process before the resin structure is fully formed. The first pattern portion is formed with fibers oriented in a first direction, and the second pattern portion is formed with fibers oriented in a second direction, allowing the depth effect to be built into the structure during fabrication rather than added later.
3Shape
If different fiber widths are used in different regions, then pattern differentiation is improved, but material selection complexity increases
Solution Approach 1:
The patent applies local quality by specifying different fiber widths for different pattern portions - the first pattern portion uses fibers with a first fiber width while the second pattern portion uses fibers with a second fiber width. This creates locally differentiated properties that enable both stiffness and three-dimensional depth effects in different areas of the same structure.
Solution Approach 2:
The patent applies parameter changes by varying the fiber width parameter across different regions of the resin structure. The invention specifies that fibers in the first pattern portion have a first fiber width while fibers in the second pattern portion have a second fiber width, allowing material selection to be optimized for different functional requirements in different areas.

AI summary
A resin structure (10) includes a first structural portion (20) and a second structural portion (30). The first structural portion (20) includes a characteristic design surface (10S) and structures an end portion at a side of the resin structure (10) at which the characteristic design surface (10S) is disposed. An orientation direction of fibers in a first pattern portion (22) of the first structural portion (80) differs from an orientation direction of fibers in a second pattern portion (24, 26). The second structural portion (30) includes a region disposed at the opposite side of the first structural portion (20) to the side at which the characteristic design surface (10S) is disposed. Fibers contained in the second structural portion differ in fiber width from the fibers contained in the first structural portion (20). A portion of the fibers contained in a region of the second structural portion (30) superposed with the first structural portion (20) are configured to be visible through the resin of the first structural portion (20).
