Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing size of wind turbine nacelles requires numerous custom-made canopy panels, leading to time-consuming and labor-intensive manufacturing processes, as well as logistical challenges with storage and transportation, due to the need for multiple molds and tools.
Innovation Solution
A canopy structure composed of standard panels with a flange along one edge, which are identical in size and shape, reducing the number of different parts and tools required, and allowing for a self-carrying load-bearing structure without a heavy metal frame, facilitating cost-effective production and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If numerous custom-made cover sheets are prepared for increasing nacelle size, then the canopy structure can accommodate larger equipment, but the manufacturing time and labor intensity increase significantly
Solution Approach 1:
The canopy structure is divided into multiple standardized panels that can be manufactured independently and assembled together. Each panel is a modular unit with standardized dimensions and connection features, allowing parallel production and reducing overall manufacturing time while accommodating large nacelle volumes.
Solution Approach 2:
Standardized panels are designed with universal connection features (flanges, bolts, sealing elements) that can be used across different panel positions and configurations. This universality allows the same panel design to serve multiple functions and locations, reducing the variety of custom parts needed and improving manufacturing efficiency.
2Adaptability or versatility
If numerous custom-made cover sheets are prepared with different molds and cutting tools, then the canopy structure can be customized for individual placements, but the device complexity and tool requirements increase
Solution Approach 1:
A standardized panel design with universal connection features (flanges, mounting holes, sealing interfaces) is developed that can be adapted to various positions and configurations through arrangement and orientation rather than custom manufacturing. This reduces the number of unique molds and cutting tools required while maintaining adaptability.
Solution Approach 2:
Multiple customization requirements are merged into a single standardized panel design that can fulfill various functional needs through strategic placement and configuration. The standardized connection system allows different panel arrangements to achieve custom canopy shapes without requiring custom panels for each configuration.
3Productivity
If bigger cover sheets are made to reduce the number of panels, then the number of assembly operations decreases, but the storage and transportation requirements increase
Solution Approach 1:
The canopy is segmented into multiple standardized panels of manageable size that can be stored and transported efficiently using standard logistics infrastructure. The modular design allows panels to be stacked and transported in compact configurations, avoiding the need for large specialized storage facilities while maintaining assembly efficiency.
Solution Approach 2:
The panel dimensions are optimized to balance assembly efficiency with transportability. By changing the size parameters of individual panels to standardized dimensions, the design achieves a compromise where panels are large enough to reduce assembly operations but small enough to fit standard transportation and storage capabilities.
4Shape
If individual custom-made panels are prepared for each placement, then the canopy structure can fit specific nacelle configurations, but the loss of time in preparation procedures increases
Solution Approach 1:
The canopy is divided into standardized panels that can be pre-manufactured using common molds and tools. The segmentation allows for efficient batch production of identical panels while the overall configuration is achieved through the arrangement of these standard units, significantly reducing preparation time compared to custom-making each panel.
Solution Approach 2:
Standardized panels are designed with pre-integrated connection features (flanges, mounting holes, sealing elements) that are prepared in advance during manufacturing. This preliminary preparation of connection interfaces eliminates time-consuming on-site customization and fitting operations, allowing for rapid assembly while maintaining precise geometric fit.

AI summary
A canopy structure (9) for a nacelle (3) of a wind turbine (1), comprising at least one side (RS, LS, BS) and a plurality of standard panels (28) which all have the same length (L) and the same width (W), wherein the at least one side (RS, LS, BS) is at least partly formed from the plurality of standard panels (28), and wherein each standard panel (28) comprises a flange (30) which runs only along one edge (E1, E2, E3, E4) of the standard panel (28). Advantageously, the canopy structure (9) comprising the standard panels (28) is able to reduce the need of a high number of different canopy parts. The amount of different types of molds or tools for producing the standard panels (28) is reduced which leads to a more cost-effective production of the canopy structure (9). Lowering of the number of parts simplifies the logistics related to production, transport, storage and assembly. Simple shaped parts like the standard panels (28) and high numbers of identical parts makes transportation more cost-effective.
