Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment caps for hand-held power tools do not effectively protect the tool interface while providing focused illumination for the workspace.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional attachment cap is used to protect the tool interface, then the interface protection function is provided, but the illumination of the workspace is not focused and effective
Solution Approach 1:
The patent combines the interface protection function and the focused illumination function into a single attachment cap. The ring lens is integrated into the cap structure, allowing it to both protect the tool interface and focus light from the lighting element onto the workspace simultaneously, eliminating the need for separate protection and illumination devices.
Solution Approach 2:
The ring lens acts as an optical intermediary between the lighting element and the workspace. It receives light from the lighting element and focuses it onto the workspace, transforming the diffuse light into concentrated illumination while being integrated into the protective cap structure.
2Ease of operation
If light guide elements are added to focus light, then the workspace illumination is improved, but the device complexity increases
Solution Approach 1:
The ring lens is positioned at a specific location on the attachment cap, directly above the lighting element, to provide localized focused illumination. This strategic placement ensures that light is directed precisely where needed on the workspace while maintaining a simple overall structure.
Solution Approach 2:
The ring lens utilizes its curved optical surface to focus light from the lighting element onto the workspace. The spherical or aspherical geometry of the lens enables effective light concentration and direction control through optical refraction, achieving precise light control without complex mechanical adjustment mechanisms.
