Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamp pliers with crimping and shearing functions require cumbersome adjustments and can lead to operational mistakes, especially for unskilled workers when switching between these functions.
Innovation Solution
An adjusting-free clamp pliers jaw design featuring mirror-symmetrical first and second pliers bodies with integrated clamping rims and extrusion notches, allowing for simultaneous crimping and shearing without conversion operations, ensuring stable and simple operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an eccentric shaft adjustment mechanism is used to switch between crimping and shearing functions, then the device can achieve multiple functions, but the operation becomes cumbersome and error-prone due to required adjustments
Solution Approach 1:
The pliers jaw is segmented into two mirror-symmetrical bodies (first pliers body and second pliers body) with distinct functional features on each. The first pliers body has a clamping rim for crimping, while the second pliers body has an extrusion notch for shearing. This segmentation allows each body to be optimized for its specific function without requiring adjustments, eliminating the complexity of switching mechanisms while maintaining multi-functionality.
2Adaptability or versatility
If an adjustable mechanism is provided to switch between different functions, then the device can perform multiple operations, but the device complexity increases
Solution Approach 1:
The invention merges crimping and shearing functions into a single integrated pliers jaw structure without requiring separate adjustment mechanisms. The mirror-symmetrical design integrates both functional elements (clamping rim and extrusion notch) into one component that can perform both operations, eliminating the need for complex switching mechanisms and reducing overall device complexity.
Solution Approach 2:
The pliers jaw is designed as a universal component that can perform both crimping and shearing functions through its mirror-symmetrical structure. Each pliers body contains specific features (clamping rim for crimping, extrusion notch for shearing) that enable the single component to handle multiple operations without requiring additional adjustment mechanisms or complex switching systems.
3Adaptability or versatility
If adjustment mechanisms are included for function switching, then the device can adapt to different tasks, but the operation time increases due to adjustment requirements
Solution Approach 1:
The pliers jaw is pre-configured with mirror-symmetrical bodies that have predetermined functional features (clamping rim and extrusion notch) ready for immediate use. This preliminary configuration eliminates the need for time-consuming adjustments during operation, as both crimping and shearing functions are already prepared and accessible without requiring any switching or adjustment actions.

AI summary
An adjusting-free clamp pliers jaw, the first and second pliers bodies rotating on the base and the first and second pliers bodies being mirror symmetrical, the clamping rim is provided on both the first and second pliers bodies, the extrusion notch is provided on both the first and second pliers bodies, the clamping rims on the first and second pliers bodies are jointly used for clamping a clamp, and the extrusion notches on the first and second pliers bodies are used for jointly pinching off the clamp. The invention brings following benefits that: the clamping rims and the extrusion notches are arranged on the first and second pliers bodies, so that a clamping and breaking of the clamp from the extrusion can are realized and both the crimping and shearing functions can be integrated together without a conversion operation, and an operation of this device is simple, convenient and quick.
