Rivet Nut Tool Linkage Structure for Lower Handle Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rivet guns require excessive effort to open or close handles due to unreasonable force arm design, making them time-consuming and energy-consuming, especially for individuals who are not strong, necessitating the use of both hands.
Innovation Solution
The rivet gun incorporates a linkage assembly system where the first linkage assembly provides a backward force to the U-shaped seat, and a second linkage assembly further assists, allowing for easier opening and folding of the right handle by generating two opposing forces, reducing the energy required for operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the traditional rivet gun structure is used, then the riveting function is achieved, but excessive effort is required to open or close the handles
Solution Approach 1:
The patent applies dynamics by making the handle connection dynamic rather than fixed. The right handle is connected to the housing through a rotation connection that allows the handle to pivot and move relative to the housing during operation. This dynamic connection enables the handle to automatically adjust its position and leverage ratio during the riveting cycle, reducing the force required to operate it while maintaining the riveting function.
Solution Approach 2:
The patent changes the parameter of the connection type between the right handle and housing from a fixed rigid connection to a rotational pivot connection. This parameter change allows the handle to move through different angular positions, changing the mechanical advantage dynamically during operation. The rotation connection enables the handle to achieve favorable leverage ratios at different stages of the riveting cycle, reducing the force required to open and close the handles.
2Productivity
If the traditional rivet gun structure is used, then the basic riveting function is provided, but the operation is time-consuming and energy-consuming
Solution Approach 1:
The dynamic rotation connection between the right handle and housing allows the handle to automatically optimize its leverage ratio during the riveting cycle. As the handle moves through different angular positions, the mechanical advantage changes dynamically, enabling faster operation with less energy input. This dynamic adjustment eliminates the need for excessive force application and reduces the time required to complete each riveting operation.
Solution Approach 2:
The rotation connection enables the handle to self-adjust its position and leverage ratio during operation without requiring additional energy input or complex control mechanisms. The mechanical system automatically optimizes itself as the handle moves, reducing the energy required for operation and increasing the speed of the riveting process.
