Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld power tools lack effective illumination of the tool component and workpiece interaction area, hindering precise manufacturing processes due to inadequate visibility.
Innovation Solution
A ring-shaped lighting module with adjustable light sources, including LEDs, is integrated into the handheld power tool, providing direct and multi-angled illumination while being transparent or translucent to minimize obstruction, and optionally incorporating a particle guiding surface for cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lighting module with a ring-shaped main body and light sources is integrated close to the tool component, then illumination intensity and visibility of the workpiece interaction area is improved, but device complexity increases
Solution Approach 1:
The lighting module is integrated into the existing handheld power tool structure by combining it with the base plate or tool housing. The ring-shaped main body merges with the tool's structural elements, and the light sources are incorporated into existing mounting locations, thereby reducing overall device complexity while achieving improved illumination of the workpiece interaction area.
Solution Approach 2:
The ring-shaped main body of the lighting module serves multiple functions: it provides structural support for the light sources, acts as a mounting interface for integration with the handheld power tool, and potentially serves as a protective barrier or guide for particles. This multi-functionality reduces the need for separate components, thereby managing device complexity while maintaining illumination effectiveness.
2Loss of information
If the main body is made transparent or translucent to reduce obstruction, then visibility through the main body is improved, but manufacturing complexity increases
Solution Approach 1:
The main body is manufactured from materials with specific optical parameters (transparent or translucent properties) that allow light transmission while maintaining structural integrity. By selecting materials such as transparent plastics or translucent polymers, the design achieves visibility through the main body without requiring complex manufacturing processes, as these materials can be formed using standard injection molding or similar techniques.
3Illumination intensity
If multiple light sources are disposed at different locations on the main body to illuminate from multiple angles, then illumination quality and shadow reduction is improved, but device complexity and energy consumption increase
Solution Approach 1:
The illumination system is segmented into multiple discrete light sources positioned at different locations on the ring-shaped main body. Each light source independently illuminates a specific sector of the workpiece interaction area, collectively providing comprehensive coverage from multiple angles. This segmentation allows for targeted illumination while maintaining manageable device complexity through modular arrangement.
Solution Approach 2:
Different regions of the workpiece interaction area receive tailored illumination from light sources positioned at optimal locations on the main body. Each light source is strategically placed to illuminate specific zones where shadows would otherwise form, creating locally optimized illumination quality across the entire workspace without requiring excessive numbers of light sources.
4Illumination intensity
If the lighting module is integrated close to the tool component for direct illumination, then visibility of the tool component is improved, but the risk of obstruction by the main body increases
Solution Approach 1:
The main body of the lighting module is constructed as a thin, transparent or translucent structure that minimizes light obstruction while maintaining its structural function. This thin-film approach allows light to pass through the main body with minimal interference, enabling the lighting module to be positioned close to the tool component for direct illumination without significantly obstructing the view or light paths.
