Pivotally Coupled Handles for Pipe Cutting and Can Lid Gripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools are inadequate for efficiently cutting pipes and gripping can lids, as they lack a unified mechanism for both tasks, often requiring separate tools and not providing a secure grip or precise cutting.
Innovation Solution
A combination cutting tool with pivotally coupled arcuate handles, a transverse arcuate support, and a complementary blade for cutting, along with serrated grips for engaging can lids, allowing for simultaneous pipe cutting and can opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate tools are used for cutting pipes and gripping can lids, then each tool can be optimized for its specific function, but the user must carry and switch between multiple tools, reducing convenience and efficiency
Solution Approach 1:
The patent combines a pipe cutting function and a can lid gripping function into a single tool. The handles incorporate both a cutting blade mechanism and gripping surfaces with serrated edges, allowing the user to perform both tasks with one tool rather than switching between separate tools
Solution Approach 2:
The tool is designed with universal functionality to handle multiple tasks: the handles serve dual purposes as both gripping surfaces for can lids (with serrated edges) and as part of the cutting mechanism (with integrated blade). This multi-functional design eliminates the need for separate specialized tools
2Ease of operation
If a unified mechanism is used for both pipe cutting and can lid gripping, then user convenience and efficiency are improved, but the design complexity and difficulty of achieving secure grip and precise cutting simultaneously increase
Solution Approach 1:
The handles are segmented into distinct functional zones: one portion features serrated edges for gripping can lids, while another portion incorporates the cutting blade mechanism for pipe cutting. This segmentation allows each function to be optimized independently within the unified handle structure
Solution Approach 2:
Different portions of the handles have different local qualities: the gripping surfaces have serrated textures for enhanced friction and grip security, while the cutting portion has a smooth, rigid structure to accommodate the blade. This local differentiation enables both functions to perform optimally within the same tool
3Strength
If the handles are made rigid for structural stability, then the tool can withstand cutting forces, but the grasps may not conform to user hand shapes, reducing comfort and grip security
Solution Approach 1:
The grasps are formed with arcuate or curved surfaces that conform to the natural shape of human hands. This curvature provides ergonomic comfort and secure grip while the overall handle structure remains rigid to withstand cutting forces

AI summary
A combination gripping and cutting tool for cutting pipe and gripping can lids includes a pair of handles that are rigid. Each handle comprises a grasp that is arcuate. The handles are pivotally coupled, such that the grasps are opposing. A support, which is arcuate, extends transversely from a respective grasp. A channel is positioned in the support. A blade that extends transversely from a respective grasp is complementary to and positioned through the channel. Each of a pair of cutouts is positioned in a respective grasp. The cutouts are arcuate and opposing. Each of a pair of grips is coupled to a respective cutout. The grips are configured to engage a lid of a can when the grasps are pivoted inwardly. The handles are positionable with the support separated from the blade, such that a pipe is positionable between the blade and the support for cutting.
