Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool attachments lack effective illumination at the working end, making it difficult for users to perform tasks in low-light environments.
Innovation Solution
A sleeve with an inner and outer wall, housing a power module and multiple LEDs, coupled to a tool shaft via a reversible design, featuring a switch for user activation and a compression collar for secure attachment, providing adjustable illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lighted tool shaft attachment is added to provide illumination, then visibility at the working end is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functional components (lights, power module, switch, sleeve) into a single integrated attachment assembly that couples to the tool shaft. This merging approach provides complete illumination functionality while maintaining a unified, manageable structure rather than separate discrete components.
Solution Approach 2:
The attachment design incorporates multiple functions within a single device: illumination provision, power storage, user control, and secure attachment to the tool shaft. This multi-functionality reduces the need for separate devices and simplifies the overall system while delivering comprehensive lighting capability.
2Illumination intensity
If a power module with multiple lights is integrated into the sleeve, then illumination coverage is improved, but weight of the attachment increases
Solution Approach 1:
The attachment incorporates a reversible coupling mechanism that allows the sleeve to be easily attached and removed from the tool shaft. This dynamic design enables users to add the weighted illumination components only when needed, rather than permanently increasing the tool's weight, thus balancing illumination coverage with portability requirements.
3Ease of operation
If a reversible coupling mechanism is used to attach the sleeve to the shaft, then ease of operation is improved, but reliability of attachment may worsen
Solution Approach 1:
The attachment system is segmented into distinct components (sleeve, compression collar, tool shaft) that can be independently assembled and disassembled. This segmentation enables easy installation and removal through simple sequential steps while maintaining secure attachment during use, as each component serves a specific function in the attachment sequence.

AI summary
A lighted tool shaft attachment for lighting a work space at a working end of the tool includes a sleeve that comprises an inner wall and an outer wall, which define an interior space. The inner wall also defines a channel that is positioned longitudinally through the sleeve and configured for insertion a shaft of a tool. The sleeve is reversibly couplable to the shaft. A power module is coupled to the sleeve and positioned in the interior space. A plurality of lights is coupled to a first end of the sleeve. A switch, which is coupled to the outer, is operationally coupled to the power module and the plurality of lights. The switch is configured for activation by a user to couple the power module to the lights. The lights are configured to illuminate a work space at a working end of the shaft of the tool.
