Driving Tool Signaling Assembly for Mode Reset Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing driving tools for fastening means lack user convenience in automatic resetting operations, leading to unexpected mode changes that can result in unintended operation modes when the user places the tool on a workpiece after a resetting operation has occurred.
Innovation Solution
Incorporating a signaling assembly that emits feedback signals to the user before, during, or after automatic resetting operations, allowing the user to be informed of the mode change and enabling them to decide whether to continue in single shot or bump firing mode, using a combination of optical, acoustic, or haptic signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic resetting operation is implemented without user notification, then the device can automatically switch from bump firing mode to single shot mode, but the user may be unaware of the mode change leading to unexpected operation behavior
Solution Approach 1:
The patent applies feedback by providing user notification mechanisms (visual, acoustic, or haptic signals) that inform the user about the current operating mode and any mode changes. This feedback loop ensures the user is aware of automatic resetting operations while maintaining automated mode switching functionality.
Solution Approach 2:
The patent implements preliminary action by notifying the user in advance before an automatic mode change occurs. The notification system alerts the user prior to the resetting operation, allowing them to be prepared for the upcoming mode transition and adjust their usage accordingly.
2Ease of operation
If multiple notification channels (optical, acoustic, haptic) are provided for resetting operations, then user convenience is significantly improved, but device complexity increases
Solution Approach 1:
The patent applies universality by implementing a multi-functional signaling assembly that can operate in multiple notification modes (optical, acoustic, haptic). This single assembly provides various types of user feedback depending on the situation, reducing the need for separate notification systems while improving user convenience through diverse feedback options.

AI summary
This relates to a driving tool for driving fastening means, nails/staples, into a workpiece, a trigger lever, which can be actuated manually, and a workpiece contact element, which can be actuated by placing the tool onto the workpiece, the tool operates in a single shot mode, in which each individual sequence of an actuation of the workpiece contact element with subsequent actuation of the trigger lever triggers a driving-in cycle, the tool operates in a bump firing mode, in which, with the trigger lever continuously actuated, each individual actuation of the workpiece contact element triggers a driving-in cycle, a resetting assembly providing, by means of which the tool is resettable from the bump firing mode into single shot mode in an automatic, time-controlled resetting operation. It is proposed that a signaling assembly, which emits a feedback signal to the user before, after or during each automatic resetting operation, is provided.
