Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oscillating power tools often lack effective lighting solutions that provide sufficient illumination for workpieces in dimly lit conditions, limiting their usability.
Innovation Solution
An oscillating power tool with a lighting assembly featuring a lens, holder, and light emitting diodes (LEDs) arranged on printed circuit boards, projecting a wide-angle beam of light through a transparent lens, with a rib and adhesive securing wires and boards, and a battery pack powering the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lighting assembly is added to illuminate the workpiece, then visibility in dimly lit conditions is improved, but device complexity increases
Solution Approach 1:
The lighting assembly is integrated into the housing structure of the oscillating power tool, with the lens mounted on the front face and the holder coupled to the lens, merging the lighting function with the existing tool structure rather than adding a separate independent lighting device
Solution Approach 2:
The housing structure serves multiple functions: it contains the motor and drive mechanism, provides structural support, and simultaneously houses the lighting assembly with the lens, holder, printed circuit boards, and light emitting diodes, making the housing a multi-functional component
2Illumination intensity
If multiple printed circuit boards with LEDs are used to provide wide-angle illumination, then illumination coverage is improved, but manufacturing complexity increases
Solution Approach 1:
The lighting assembly uses multiple printed circuit boards with light emitting diodes arranged in a specific configuration, with each board containing LEDs that collectively provide wide-angle illumination coverage when activated
Solution Approach 2:
The holder serves as an intermediary structure that supports the multiple printed circuit boards and positions them correctly relative to the lens, facilitating assembly and maintaining the precise arrangement needed for wide-angle illumination

AI summary
An oscillating power tool has a housing including a handle portion defining a handle axis and a head portion defining an output axis that is perpendicular to the handle axis. The head portion includes a front face intersected by the handle axis. A drive mechanism includes an output shaft configured to oscillate about the output axis in a rotational manner in response receiving torque from a motor. A lighting assembly is configured to illuminate a workpiece in front of the head portion of the housing. The lighting assembly includes a lens arranged on the front face of the housing, a holder coupled to the lens, a plurality of printed circuit boards supported by the holder, and an LED arranged on each of the printed circuit boards. In response to being activated, the LEDs are configured to project a wide-angle beam of light through the lens.
