Intersecting Cylinder Driver Tool Handle Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving tools are inefficient in size reduction, leading to increased length and operational challenges due to parallel arrangement of compression and driving cylinders, which results in protrusion and inefficient handle placement.
Innovation Solution
A driving tool design where the compression cylinder intersects and extends alongside the magazine, with the handle positioned opposite to the magazine, allowing the compression cylinder to slide alongside the magazine, reducing overall length and improving handle proximity to the driving axis, thus enhancing operability and reducing recoil moments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the compression cylinder and driving cylinder are disposed in parallel with each other, then the compression device can generate compressed air effectively, but the rear region of the compression cylinder protrudes rearward of the driving cylinder, increasing the overall length of the driving tool
Solution Approach 1:
The patent changes the spatial arrangement from a parallel configuration to an intersecting configuration where the compression cylinder extends in a direction alongside the magazine rather than parallel to the driving cylinder. This dimensional reorganization allows the compression cylinder to be positioned without protruding rearward, thereby reducing the overall length of the driving tool while maintaining its compressed air generation capability.
2Power
If the compression cylinder is positioned to generate compressed air with sufficient stroke, then the compression function is effective, but the handle placement becomes less optimal and the driving tool length increases
Solution Approach 1:
By repositioning the compression cylinder to extend alongside the magazine in an intersecting arrangement, the patent creates optimal space for handle placement. The handle can be positioned on the opposite side of the first cylinder from the magazine, improving ergonomics and operability while the compression cylinder maintains its functional stroke length.
3Length of moving object
If the first cylinder is arranged to intersect with the second cylinder and extend alongside the magazine, then the overall length of the driving tool is shortened, but the structural complexity increases
Solution Approach 1:
The patent implements an intersecting arrangement where the first cylinder extends alongside the magazine rather than parallel to the second cylinder. This spatial reorganization shortens the overall length of the driving tool. The compressed air supply passage connects the two cylinders, and the valve member controls the air flow, achieving compact design without excessive structural 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 achieves size reduction of the driving tool, improves handle placement for efficient operation, and reduces energy losses by optimizing the compressed air supply passage and component arrangement.
Implementation Method 1
a first piston that is disposed so as to be slidable within the first cylinder and is configured to generate compressed air in the first cylinder
Implementation Method 2
The compressed air in the first cylinder is supplied into the second cylinder and the second piston is linearly moved toward a front end of the second cylinder by the compressed air

AI summary
A driving tool includes a first cylinder that generates compressed air by reciprocating movement of a first piston slidably disposed therein. A longitudinal direction of the first cylinder intersects a longitudinal direction of a second cylinder and extends alongside a magazine that feeds fasteners onto an axis of movement of a driving part of a second piston. The first piston reciprocally slides in a direction that extends alongside the magazine. A tool handle is disposed on the side of the first cylinder that is opposite from the magazine in the direction of the axis of movement.
