Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvemanufacturing costsVSAvoiddevice complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
ImproveversatilityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improveease of useVSAvoidmanufacturing precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

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

Inventive Principle:
Principle #25Self-service

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

Inventive Principle:
Principle #15Dynamics

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.
