Thrust Rivet Gun Screw Hinge Eliminates Link Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rivet guns have complex structures and high manufacturing costs due to the use of link mechanisms, which complicates the riveting process and increases production expenses.
Innovation Solution
A thrust rivet gun design featuring a U-shaped rivet holder with a movable mount, dead lever, and retractable spring, eliminating the need for a link mechanism by using a screw and nut hinge system and multiple nozzles for different rivet sizes, allowing for a simpler structure and lower production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a link mechanism is used in the rivet gun, then the riveting function is achieved, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The patent extracts and removes the link mechanism from the rivet gun structure, replacing it with a direct thrust transmission system where the handle directly transmits force to the rivet through a simplified mechanical arrangement, thereby eliminating unnecessary components while maintaining the core riveting function
Solution Approach 2:
Instead of using a link mechanism to indirectly transmit force, the patent inverts the approach by directly applying thrust force through the handle to the rivet, reversing the traditional indirect transmission path into a direct force application system
2Reliability
If a link mechanism is used in the rivet gun, then the riveting function is achieved, but the manufacturing cost increases
Solution Approach 1:
By extracting the link mechanism from the design, the patent reduces the number of parts that need to be manufactured, assembled, and quality-checked, directly lowering manufacturing costs while preserving the essential riveting capability through a more economical direct-thrust design
3Adaptability or versatility
If multiple nozzles are provided for different rivet sizes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the nozzle as a multi-functional component that can accommodate different rivet sizes, allowing a single nozzle structure to serve multiple purposes rather than requiring separate nozzles for each rivet type, thereby maintaining adaptability while reducing overall device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design simplifies the riveting process and reduces manufacturing costs by eliminating the link mechanism, enabling efficient riveting without the need for complex linkages, while accommodating various rivet sizes with multiple nozzles.
Implementation Method 1
a retractable spring is set between the rivet grasping mechanism at the front end of the dead lever and the bottom of the rivet holder
Implementation Method 2
The top end of the movable mount is linked with a sleeve and the top of the sleeve has a nozzle. On either side of the said movable mount lays a groove, and a pin rod is inserted in the two grooves respectively. The pin rod is hinged with the mounting hole which is on the top end of the handle
