Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a pliers tool design is used with fixed jaw and toggle lever mechanism, then cutting and stripping functions can be achieved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The tool is divided into modular components including interchangeable cutting blades, stripping blades, and a carriage system that can be independently manufactured and assembled, simplifying production and reducing costs
Solution Approach 2:
The scissor tool incorporates multiple functions (cutting, stripping, rotating) within a single basic mechanism, eliminating the need for separate specialized tools and reducing overall device complexity
2Adaptability or versatility
If multiple specialized tools are used for different cable operations, then specific functions are optimized, but the quantity of components and storage requirements increase
Solution Approach 1:
A single scissor tool handles cutting, stripping, and rotating operations through interchangeable blades and a rotating mechanism, replacing multiple specialized tools and reducing component quantity
Solution Approach 2:
The cutting function and stripping function are merged into one tool body, with both operations performed by the same scissor mechanism using different blade configurations
3Ease of operation
If a scissor tool design with integrated actuating elements is used, then ease of operation improves, but the manufacturing precision requirements increase
Solution Approach 1:
The spring mechanism automatically returns the carriage to its initial position after each cutting or stripping operation, eliminating the need for manual resetting and simplifying operation
Solution Approach 2:
The tool incorporates movable and interchangeable components that can be easily adjusted or replaced during operation, allowing adaptability without requiring high manufacturing precision for fixed configurations

AI summary
The invention relates to a shearing tool (1) comprising a first shearing part (2) and a second shearing part (3). The two shearing parts (2, 3) are pivotably mounted to one another about a shear pivot axis (5) via a shear bearing (4). By pivoting the shearing parts (2, 3), a cable inserted into a cutting blade jaw (57) can be cut. The shearing tool (1) provides an additional function by integrating an actuating element (28) into a finger receptacle (51) of the shearing part (2). The shearing part (2) has insertion openings (55) into which a cable can be inserted. The actuating element (28) allows a wire stripper to be moved between an insertion position and a cutting position. In the cutting position, the wire stripper creates a circumferential cut in the cable to enable subsequent stripping.
