Driving Tool Light Guide for Nozzle Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving tools face complexity in assembly and reduced illumination efficiency due to the routing of wires for powering illuminators, which often results in shadowing of the nozzle area, complicating the assembly process and reducing visibility during fastener driving.
Innovation Solution
Incorporating a light guide between the illuminator and the nozzle allows light to travel perpendicular to an inclined surface, ensuring concentrated and efficient illumination around the nozzle, while simplifying the routing of power wires and reducing shadowing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the illuminator is located rearward from the magazine in the driving direction, then the wire routing from power supply to illuminator is simplified, but the area around the nozzle is shadowed by the magazine and cannot be illuminated effectively
Solution Approach 1:
The illumination function is segmented into two independent parts: the illuminator positioned rearward for easy wire routing, and the light guide positioned at the magazine front for effective nozzle illumination. This segmentation allows each component to optimize its position for its specific function without compromising the other.
Solution Approach 2:
The light guide acts as an intermediary element that transfers light from the rearward-positioned illuminator to the frontward-positioned nozzle area. This intermediary allows the illuminator to be positioned for easy assembly while still achieving effective illumination of the nozzle area.
2Use of energy by moving object
If the wire is routed along the side portion of the magazine, then the illuminator can be powered, but the magazine structure becomes more complex and assembly time increases
Solution Approach 1:
The wire routing function is extracted from the magazine structure and relocated to the body. The wire runs from the power supply through the body to the illuminator, bypassing the magazine entirely. This removes the complex wire routing requirement from the magazine design.
Solution Approach 2:
The body serves as a universal routing path for both the power supply wire and the light guide. By using the body as a multi-functional structural element for routing purposes, the design avoids adding complexity to the magazine while still achieving the required power and light transmission.
3Illumination intensity
If the light source is positioned to illuminate the nozzle area, then visibility is improved, but the wire routing becomes more difficult and assembly is complicated
Solution Approach 1:
The illumination system is segmented into the illuminator component (positioned rearward for easy assembly) and the light guide component (positioned at the magazine front for effective illumination). This segmentation allows independent optimization of assembly ease and illumination effectiveness.
Solution Approach 2:
Instead of positioning the illuminator directly at the nozzle (frontward position), the system uses a rearward-positioned illuminator connected via light guide. This dimensional repositioning allows the illuminator to be assembled easily from the rear while still achieving frontward illumination through the light guide medium.

AI summary
A driving tool allows easy assembly and effective illumination of an area around a nozzle. A driving tool includes a striking mechanism that strikes a fastener, a body including the striking mechanism and an illuminator, a nozzle to allow ejection of the fastener struck by the striking mechanism, and a light guide between the illuminator and the nozzle.
