Solution Overview
Problem
Current workpiece alignment methods are cumbersome and prone to measurement errors, especially when dealing with elongated objects like pipes, as they require precise angular positioning and repositioning without rotation or translation, which is difficult to achieve accurately using existing devices.
Innovation Solution
A workpiece alignment device featuring an absolute direction indicator and adjustable fastening device that allows for precise alignment and repositioning along specific axes, using a combination of direction indicators and interchangeable transition pieces to ensure accurate angular positioning and minimize unwanted movement, with options for digital or analog display and adjustable transmission ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional alignment methods are used for elongated workpieces, then the workpiece can be repositioned, but measurement errors increase and alignment precision deteriorates
Solution Approach 1:
The patent replaces conventional mechanical alignment methods with a magnetic field-based alignment system. Magnetic alignment indicators are attached to the workpiece and alignment target, eliminating the need for complex mechanical measurement tools and reducing measurement errors during repositioning operations.
Solution Approach 2:
The patent uses visually distinct magnetic alignment indicators that provide clear visual feedback for alignment status. The indicators change position or appearance based on alignment accuracy, making it easy to determine when the workpiece is correctly positioned without complex mechanical measurements.
2Adaptability or versatility
If the workpiece is repositioned multiple times during machining, then different machining operations can be performed, but the complexity of maintaining angular position increases
Solution Approach 1:
The magnetic alignment system replaces complex mechanical alignment devices with simple magnetic indicators and targets. This allows multiple repositioning operations while maintaining angular position through simple visual checks rather than complex mechanical measurements.
Solution Approach 2:
The magnetic alignment indicators are attached directly to the workpiece, allowing the workpiece itself to indicate its alignment status. This eliminates the need for external alignment devices and simplifies the repositioning process for multiple machining operations.
3Manufacturing precision
If precise angular positioning is required without rotation or translation, then machining accuracy improves, but the difficulty of achieving this positioning increases
Solution Approach 1:
The patent uses magnetic fields to provide precise angular positioning feedback without requiring complex mechanical positioning mechanisms. The magnetic indicators automatically show when the correct angular position is achieved, eliminating the need for manual measurement and adjustment.
Solution Approach 2:
The magnetic alignment indicators provide immediate visual feedback on angular positioning accuracy. The indicators show clearly when the workpiece is at the correct angle, allowing operators to achieve precise positioning without trial and error or complex measurements.
