Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for adjusting projecting members of workpieces, such as transition pieces in turbine systems, are inaccurate and inefficient, often requiring manual alignment using tools like mallets, which can lead to misalignment and inefficiency.
Innovation Solution
A fixture system that includes holding devices to secure the workpiece and adjustment devices capable of moving projecting members along multiple axes, such as x, y, and z axes, with hydraulic or pneumatic actuators, allowing precise and efficient alignment within specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment methods using mallets are used to align projecting members, then the adjustment process can be performed with simple tools, but the alignment accuracy deteriorates and the process becomes inefficient
Solution Approach 1:
The patent replaces manual mechanical adjustment methods (using mallets and visual estimation) with an automated system that uses electronic sensors, digital displays, and motorized actuators to achieve precise alignment of projecting members, thereby improving both accuracy and efficiency
Solution Approach 2:
The patent uses digital replication of alignment measurements and positions through electronic sensors and display systems, allowing for precise measurement and adjustment without relying on manual visual estimation, thus improving alignment accuracy
2Manufacturing precision
If multiple adjustment devices are added to improve alignment precision, then the positioning accuracy improves, but the device complexity increases
Solution Approach 1:
The patent designs adjustment devices that can operate along multiple axes (X, Y, Z) and perform both positioning and alignment functions, reducing the need for separate specialized devices while maintaining high positioning accuracy
Solution Approach 2:
The patent combines multiple adjustment functions (positioning, alignment, measurement) into integrated adjustment devices that operate cooperatively, reducing overall system complexity while achieving precise positioning

AI summary
A fixture 100 and method for adjusting a workpiece 26 are disclosed. The fixture includes a holding device 102 engageable to a workpiece to secure the workpiece, and an adjustment device 106 engageable to a projecting member of the workpiece and movable along a first axis and a second axis. Movement of the adjustment device 106 along the first axis when engaged to the projecting member adjusts the projecting member along the first axis, and movement of the adjustment device 106 along the second axis when engaged to the projecting member adjusts the projecting member along the second axis.
