Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional explosive discharge actuated tools for driving fasteners lack an efficient mechanism for rapidly adjusting the striking power applied to fasteners.
Innovation Solution
The tool incorporates a power adjusting unit comprising an adjusting pin, a latch spindle, and an engaging block, which allows for the partial or complete closure of an exhaust port to control the discharge of combustion gas, enabling easy adjustment of striking power by moving the adjusting pin relative to the barrel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional explosive discharge actuated tools use fixed discharge cartridges or simple venting control to adjust striking power, then the structure remains simple, but the adjustment speed and operational efficiency are slow
Solution Approach 1:
The patent implements a dynamic power adjusting unit with movable components including an adjusting pin that can shift position along the barrel axis, a latch spindle that can move between latched and unlatched states, and an engaging block that can be actuated to release the latch. This dynamic mechanism allows rapid adjustment of the exhaust port opening area to control combustion gas discharge and striking power, resolving the contradiction between adjustment speed and structural simplicity.
Solution Approach 2:
The power adjusting unit is segmented into distinct functional components: the adjusting pin for controlling exhaust port opening, the latch spindle for maintaining position, and the engaging block for actuation. This segmentation allows each component to perform its specific function efficiently while enabling rapid overall adjustment through coordinated movement of these modular elements.
2Force
If the exhaust port is completely closed to maximize striking power, then the piston generates maximum force, but the combustion gas cannot be discharged and power adjustment becomes inflexible
Solution Approach 1:
The patent changes the parameter of exhaust port opening area continuously by positioning the adjusting pin at different locations along the barrel axis. The exhaust port opening area can be completely closed or partially opened at any position, allowing flexible control of combustion gas discharge. This parameter change enables the system to achieve both maximum striking power (when closed) and adaptable power reduction (when partially opened), resolving the contradiction between force and adaptability.

AI summary
An explosive discharge actuated tool includes a piston disposed in a barrel to be driven by a combustion gas for exerting a striking power to strike a fastener out of the barrel. A power adjusting unit is disposed to adjust an opening area of an exhaust port for the combustion gas, and includes an adjusting pin movable longitudinally to completely or partially close the exhaust port so as to adjust the striking power, and an engaging block coupled to the adjusting pin through a latch spindle to be moved transversely to allow or prevent movement of the adjusting pin relative to the exhaust port.
