Turbine Bucket Fixture Segmentation for Axial Fixing

1Reliability

If the existing axial entry type uses a complex axial fixture configuration, then the bucket can be fixed in the axial direction, but the manufacturing costs and installation time are increased

Engineering Contradiction:

Improvebucket fixing reliabilityVSAvoidfixture configuration complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The fixture system is divided into multiple simple components: a fixture body, a positioning member inserted into the first insertion groove, and a securing member inserted into the second insertion groove. This segmentation replaces the complex single-piece fixture with multiple simple elements that collectively achieve the same fixing function while reducing manufacturing complexity and cost.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning member and securing member are nested within the fixture body structure. The positioning member fits into the first insertion groove of the bucket, while the securing member fits into the second insertion groove, creating a nested arrangement that simplifies the overall fixture configuration while maintaining reliable axial fixing.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If the existing axial entry type uses a complex axial fixture configuration, then the bucket can be fixed in the axial direction, but the installation time is increased

Engineering Contradiction:

Improvebucket fixing reliabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The fixture system is divided into multiple simple components: a fixture body, a positioning member inserted into the first insertion groove, and a securing member inserted into the second insertion groove. This segmentation replaces the complex single-piece fixture with multiple simple elements that collectively achieve the same fixing function while reducing manufacturing complexity and cost.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning member is pre-positioned in the first insertion groove to establish correct alignment before the bucket is fully installed. This preliminary positioning action simplifies the subsequent securing operation, reducing overall installation time while maintaining fixing reliability.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If the axial fixture has a complicated configuration, then the bucket can be fixed, but the manufacturing costs are increased

Engineering Contradiction:

Improvebucket fixing reliabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The fixture system is divided into multiple simple components: a fixture body, a positioning member inserted into the first insertion groove, and a securing member inserted into the second insertion groove. This segmentation replaces the complex single-piece fixture with multiple simple elements that collectively achieve the same fixing function while reducing manufacturing complexity and cost.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The positioning member and securing member are designed as simple, inexpensive components that can be easily manufactured and replaced if necessary. This approach reduces manufacturing costs compared to a complex, expensive axial fixture, while still achieving reliable bucket fixing through the combined action of multiple simple elements.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The fixture system is divided into multiple simple components: a fixture body, a positioning member inserted into the first insertion groove, and a securing member inserted into the second insertion groove. This segmentation replaces the complex single-piece fixture with multiple simple elements that collectively achieve the same fixing function while reducing manufacturing complexity and cost.
