Solution Overview

Problem

Turbine alignment is challenging in bases without axial beams due to space constraints and twisting issues, especially when external equipment limits available space for tooling, particularly at the forward or aft ends of the turbine.

Innovation Solution

An alignment assembly with a base, support legs, and a jack assembly that includes low friction plates for vertical and lateral adjustment, allowing for precise positioning of the turbine system structure without the need for axial beams, using a combination of angled support leg portions and a removable jack assembly with sliding plates for easy maneuvering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If axial beams are removed from the base assembly to accommodate external equipment, then space availability for equipment installation is improved, but turbine alignment becomes difficult due to twisting issues and lack of structural support

Engineering Contradiction:
Improvespace availabilityVSAvoidalignment difficulty
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The support leg is divided into multiple segments including a first support leg portion coupled to the base, a second support leg portion angled relative to the first, and a third support leg portion that contacts the turbine. This segmentation allows each portion to independently accommodate movement and twisting while maintaining overall alignment capability, resolving the contradiction between space availability and alignment ease.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The alignment assembly incorporates adjustable components including the angled support leg portions that can be positioned at different angles, and a jack assembly that can be vertically adjusted. These dynamic elements allow the system to adapt to twisting and movement during alignment operations, maintaining ease of operation even without axial beams.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If the forward or aft end of the turbine is moved independently for alignment, then alignment precision is improved, but twisting issues occur due to lack of structural rigidity

Engineering Contradiction:
Improvealignment precisionVSAvoidstructural stability
Core Design Contradiction:
Measurement precisionVSStability of the object's composition

Solution Approach 1:

The turbine support structure is segmented into multiple independent support leg portions rather than a single rigid beam. This allows the forward and aft ends to be supported separately, enabling independent movement for precise alignment while the segmented structure absorbs the resulting twisting stresses without compromising overall stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support leg portions are designed with adjustable parameters including angle of inclination and vertical position. By changing these parameters, the system can accommodate independent movement of turbine ends for alignment while maintaining structural stability through optimized geometric configuration.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If tooling is introduced to perform alignment operations in limited space, then alignment capability is improved, but available space for tooling becomes insufficient at forward and aft ends

Engineering Contradiction:
Improvealignment capabilityVSAvoidavailable space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The jack assembly is designed to nest within the recess formed by the angled support leg portions. This nesting arrangement allows the alignment tooling to be compact and fit within the limited space at the forward and aft ends of the turbine, maintaining alignment capability without requiring additional external space.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The support leg portions are arranged at angles to each other, creating a three-dimensional recess space rather than a flat surface. This dimensional arrangement provides access points and working space for alignment tooling in directions that would not be available with a conventional flat base, effectively increasing available space for tooling operations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
