The conventional manufacturing method for wind turbine blades is logistically demanding, requires significant overhead, and is costly due to the need for multiple workstations equipped with various tools and molds, leading to inefficiencies and quality risks as the industry scales to meet increasing demand.

Innovation Solution

The use of a set of hinge devices in multiple blade manufacturing operations, which allows for the releasable connection of different tools, provides increased flexibility and precision in manufacturing processes, reducing the need for overhead cranes and simplifying logistics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple workstations are equipped with various tools and molds for conventional manufacturing, then manufacturing capacity is increased, but device complexity and overhead costs increase significantly

Engineering Contradiction:
Improvemanufacturing capacityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

A single workstation is designed to perform multiple manufacturing operations by sequentially mounting different tools and molds. The workstation serves universal functions including molding blade shells, attaching shear webs, and curing, eliminating the need for multiple specialized workstations and reducing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically reconfigures the workstation by mounting and dismounting different tools and molds as needed for each manufacturing step. This dynamic adaptability allows one workstation to replace multiple static workstations, reducing device complexity while maintaining productivity.

Inventive Principle:
Principle #15Dynamics

2Productivity

If multiple molds are maintained at different workstations for conventional manufacturing, then production throughput is improved, but manufacturing cost increases due to production and maintenance expenses

Engineering Contradiction:
Improveproduction throughputVSAvoidmanufacturing cost
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

A single mold is designed to be reused across multiple manufacturing steps and operations. The mold is mounted at the workstation, used for forming blade shells, then reused for subsequent operations, eliminating the need to manufacture and maintain multiple identical molds while maintaining production throughput.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of discarding or maintaining multiple molds simultaneously at different workstations, the system recovers and reuses the same mold repeatedly. The mold is dismounted after use, stored, and remounted when needed, reducing manufacturing and maintenance costs while preserving productivity.

Inventive Principle:
Principle #34Discarding and recovering

3Adaptability or versatility

If all materials are transported to every workstation in conventional manufacturing, then manufacturing flexibility is maintained, but logistical complexity and time consumption increase

Engineering Contradiction:
Improvemanufacturing flexibilityVSAvoidlogistical time consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Multiple manufacturing steps that were previously distributed across separate workstations are merged into a single workstation. This consolidation eliminates the need to transport materials between multiple locations, reducing logistical time consumption while maintaining flexibility through sequential tool mounting.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Materials and components are prepared and staged in advance at the single workstation location. By consolidating all operations at one location, the system performs preliminary positioning and preparation, eliminating repeated transport cycles and reducing overall logistical time while maintaining adaptability.

Inventive Principle:
Principle #10Preliminary action
