Fastener Driver Dust Blower One-Handed Gas Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastener driving devices with built-in dust blowers are cumbersome to use, requiring two hands and having an outlet positioned awkwardly, making it difficult to clear dust from the target location efficiently.
Innovation Solution
A fastener driving device with a built-in dust blower that includes a passageway extending from a pressurized gas reservoir to an outlet near the nose assembly, equipped with an actuator that allows one-handed operation, enabling gas to be selectively communicated to the atmosphere in the direction of the fastener drive axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a built-in dust blower is added to the fastener driving device, then dust clearing capability is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The dust blower is integrated into the fastener driving device by combining the dust blower housing with the device housing, merging the dust clearing function with the fastening function into a single unified device structure
Solution Approach 2:
The device is designed to perform multiple functions: fastening operations through the drive engine and dust clearing through the integrated dust blower, allowing a single device to handle both tasks without requiring separate tools
2Ease of manufacture
If the dust blower outlet is positioned in the upper portion of the device, then structural design is simplified, but usability and operational convenience deteriorate
Solution Approach 1:
The dust blower outlet is strategically positioned in a specific location on the housing where it provides optimal dust clearing effectiveness for the target area, creating local quality improvement in the dust clearing zone rather than uniform positioning throughout the device
3Reliability
If two hands are required to operate the dust blower, then operational control is improved, but productivity and efficiency deteriorate
Solution Approach 1:
The dust blower is designed with a configuration that allows it to be operated while the device is held in one hand, enabling the user to clear dust without needing to use the other hand for additional manipulation, thus the device serves the dust clearing function autonomously during single-handed operation
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
Enables efficient one-handed operation of the dust blower, allowing users to clear dust effectively without compromising the handling of the device, improving usability in construction settings by directing the gas flow parallel to the fastener drive axis.
Implementation Method 1
A reservoir is at least partially located in the handle portion and is configured to receive a gas having a pressure greater than atmospheric pressure

AI summary
A fastener driving device includes a housing having an engine receiving portion and a handle portion. A reservoir is configured to receive a gas having a pressure greater than atmospheric pressure and is at least partially located in the handle portion. A dust blower is configured to allow gas in the reservoir to be selectively communicated to atmosphere through an outlet in the engine receiving portion of the housing. The dust blower includes a passageway extending from the reservoir to the outlet in the engine receiving portion, the passageway at least partially circumnavigating the cylinder of the drive engine, and an actuator configured to selectively open and close the passageway so that when the passageway is open, gas from the reservoir is communicated from the reservoir to the outlet, and when the passageway is closed, the gas from the reservoir is not communicated from the reservoir to the outlet.
