Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design of metal substructures for Fiber Reinforced Plastic (FRP) molds, particularly for complex wind turbine blades, is time-consuming and labor-intensive due to the need for manual creation of 3D models and manufacturing drawings, with repetitive workflows and lack of standardization, which complicates the structural analysis and optimization of the mold-supporting frameworks.
Innovation Solution
A parametric and automated software tool for metal substructure design that generates 3D models and manufacturing drawings based on input parameters and mold surface geometry, including line models for finite element analysis and solid body models for refinement, enabling automated design and optimization of metal frames for FRP molds.

Engineering Contradiction Analysis
1Productivity
If manual design methods are used for metal substructures, then design flexibility and control are maintained, but design time and labor intensity increase significantly
Solution Approach 1:
The patent replaces manual mechanical design processes with an automated computer-based system that generates metal substructure designs algorithmically. The system automatically creates 3D models, performs structural analysis, and optimizes designs without manual intervention, dramatically reducing design time while maintaining quality through computational automation.
Solution Approach 2:
The patent implements parametric modeling where design parameters can be adjusted to automatically regenerate the entire substructure design. This allows rapid exploration of different design configurations by simply changing input parameters, enabling quick iterations and optimizations without starting from scratch each time.
2Ease of manufacture
If manual creation of 3D models and manufacturing drawings is performed, then design control and customization are maintained, but standardization and repeatability deteriorate
Solution Approach 1:
The patent replaces manual drafting and modeling processes with automated computer-generated designs. The system automatically produces standardized 3D models and manufacturing drawings with consistent formatting and documentation, eliminating variability introduced by manual processes while reducing overall process complexity through automation.
Solution Approach 2:
The patent creates a universal design system that handles multiple design tasks automatically - generating 3D models, creating manufacturing drawings, performing structural analysis, and optimizing designs all within a single integrated platform. This multi-functional approach standardizes the design process across different projects and reduces the need for multiple separate tools and procedures.
3Reliability
If structural analysis is performed after design completion, then design flexibility is maintained, but design optimization opportunities are lost
Solution Approach 1:
The patent performs structural analysis during the design phase rather than after completion. The system integrates finite element analysis and other structural evaluation methods into the iterative design process, allowing designers to identify and correct structural issues early when modifications are easier and more cost-effective, thereby improving both reliability and optimization efficiency.
Solution Approach 2:
The patent implements a feedback loop where structural analysis results automatically inform design modifications. The system uses analysis outcomes to adjust design parameters and regenerate designs that meet structural requirements, creating an iterative optimization process that continuously improves structural integrity while reducing the need for post-design modifications.

AI summary
A method for manufacturing a metal frame support of a wind turbine blade mold includes receiving a wind turbine blade mold surface including a three-dimensional geometry file. The method includes receiving at least one input parameter and receiving a design scheme. The method includes outputting a first plurality of files including at least one line model wherein the line model represents a generated framework. The method includes outputting a second plurality of files comprising at least one element of geometry data which can be edited and refined. The method includes performing finite element analysis of the line model and at least one element of geometry data—thus, optimization of the substructure can be done while the design phase is not yet concluded. The method includes outputting a full frame model and outputting at least one technical drawing of the full frame model.
