Driving Tool Controller Stacked Below Motor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving tools face challenges in achieving a compact design due to the conventional arrangement of controllers, which hinder the reduction of size in the front-rear direction.
Innovation Solution
The driving tool incorporates a controller arrangement where the controller is positioned below the electric motor, which is itself located below the battery mounting section, allowing for a more compact design in the front-rear direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the controller is arranged along the mounting surface of the battery to be attached to the battery mounting section, then the controller can be accommodated, but the driving tool cannot be made compact in the front-rear direction
Solution Approach 1:
The controller arrangement transitions from a lateral placement along the battery mounting surface to a vertical stacking configuration below the electric motor. This dimensional shift utilizes the up-down direction instead of the front-rear direction, enabling compactness in the critical front-rear dimension while accommodating the controller within the existing tool structure.
2Length of moving object
If the controller is arranged below the electric motor, then the driving tool can be reduced in size in the front-rear direction, but the arrangement space must be precisely optimized
Solution Approach 1:
The controller is nested within the space below the electric motor, utilizing the vertical clearance created by the motor housing structure. This nesting approach allows the controller to be accommodated without increasing the front-rear length, as the controller fits into the existing vertical envelope defined by the motor assembly and tool body.
3Use of energy by moving object
If the battery mounting section is positioned at the rear of the grip, then power supply is secured, but the overall tool size in the front-rear direction increases
Solution Approach 1:
The tool structure is segmented into functional zones: the battery mounting section is positioned at the rear of the grip for power supply, while the electric motor and controller are stacked vertically below the grip in the tool body. This segmentation allows each component to be optimally positioned for its function while minimizing the overall front-rear length through vertical stacking of the motor and controller.

AI summary
A driving tool has a tool body, a driver that moves downward to strike a driven member, a grip extending rearward from the tool body, a battery mounting section provided at a rear part of the grip to which a battery can be attached, a motor housing extending rearward from the tool body below the grip and accommodating an electric motor that moves the driver, and a controller arranged below the electric motor to control an operation of the electric motor.
