Working Machine Magazine-Motor Layout for Compact Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large outer shape of the roll magazine in existing working machines leads to an increase in the size of the machine, degrading operability and workability, which in turn affects the usability of the machine.
Innovation Solution
The magazine is positioned to overlap with the motor as viewed in the direction of the motor's rotation axis, with a recess in the motor case to avoid interference, and the handle and motor axis are inclined to minimize machine size, along with the magazine's axis being angled to reduce interference and optimize space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the magazine is positioned to overlap with the motor, then the size of the working machine is reduced, but interference between the magazine and motor housing occurs
Solution Approach 1:
The magazine is positioned to overlap with the motor in the axial direction, nesting the magazine within the motor's spatial envelope. This allows the magazine to occupy space that would otherwise be unused, reducing the overall machine size without requiring additional external volume.
Solution Approach 2:
The magazine axis is arranged at an angle relative to the motor axis, transitioning from a conventional parallel or perpendicular arrangement to an inclined configuration. This angular arrangement allows both components to coexist in overlapping projection while minimizing physical interference, effectively utilizing three-dimensional space more efficiently.
2Ease of operation
If the magazine is positioned to overlap with the motor, then operability and workability are improved, but the motor case requires additional recess structures to avoid interference
Solution Approach 1:
The striking unit is designed with movable positioning capability, allowing it to adjust its position dynamically during operation. This flexibility enables the striking unit to navigate around the magazine and motor housing recesses, maintaining effective striking function while accommodating the compact overlapping arrangement.
Solution Approach 2:
The motor case is designed with localized recesses only in the specific regions where interference with the magazine would occur. Rather than redesigning the entire motor housing, the recesses are strategically positioned to provide just enough clearance for the magazine and striking unit to function properly in the overlapping configuration.

AI summary
A working machine 10 includes a magazine 54 that houses a plurality of fasteners inside, an ejection unit 32 to which the fastener is supplied, and a driver blade 30 that moves to a lower side in an up-down direction AR1 to strike the fastener supplied to the ejection unit 32. The working machine 10 further includes a biasing unit that biases the driver blade 30 to the lower side, a conversion mechanism 17 that winds up the driver blade 30 to the upper side in the up-down direction AR1, and an electric motor 15 that generates a driving force for driving the conversion mechanism 17. The magazine 54 is provided at a position overlapping with the electric motor 15 as viewed in a direction of a rotation axis AX2 of the electric motor 15.
