Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional flange spreading tools are used, then pipe flanges can be separated, but the tools are bulky, expensive and difficult to operate
Solution Approach 1:
The spreading tool is divided into two separate wedges that can be independently positioned and operated between the flanges, rather than using a single complex conventional tool. This segmentation allows for easier manipulation and reduced operational difficulty while maintaining the spreading function.
Solution Approach 2:
The invention extracts the essential spreading function from complex conventional tools by using simple tapered wedges that can be manually positioned and operated. The wedges are removed from any complex mounting mechanisms, allowing them to be easily inserted and removed from between flanges without requiring complex handling procedures.
2Volume of moving object
If conventional flange spreading tools are used, then pipe flanges can be separated, but the tools are bulky
Solution Approach 1:
By dividing the spreading function into two separate wedge components, the overall volume of the tool assembly is reduced. Each wedge can be independently handled and positioned, eliminating the need for a single large bulky conventional tool while maintaining effective flange separation capability.
3Ease of manufacture
If conventional flange spreading tools are used, then pipe flanges can be separated, but the tools are expensive
Solution Approach 1:
The invention employs simple tapered wedges that can be manufactured from inexpensive materials such as aluminum or steel alloys. These wedges are designed to be cost-effective and can be easily replaced if needed, eliminating the high cost associated with conventional spreading tools while maintaining operational effectiveness.
Solution Approach 2:
The invention changes the material parameters by using affordable aluminum or steel alloys instead of expensive conventional tool materials. The tapered geometry and material selection are optimized to provide sufficient spreading force at a lower manufacturing cost, making the tool economically viable while maintaining ease of operation.
