Cordless Tool Lighting Attachment With Tapered Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices for tools are bulky, cumbersome, and pose safety hazards due to cords, can cause burns, and are not easily maneuverable for precise applications, especially in medical settings where they may disrupt the surgical field and cause fatigue.
Innovation Solution
A cordless lighting device with a tapered cavity that securely attaches to tools, featuring self-locking protrusions and a split collar for secure attachment, automatic activation upon installation, and deactivation upon removal, using a compact on-board power source to provide focused illumination without the need for external power cords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lighting device with integral light source is used, then illumination is provided, but the device becomes bulky and expensive
Solution Approach 1:
The lighting device is divided into separate components: a handle portion and a lighting portion that can be detached. The lighting portion includes the light source and can be attached to or removed from the handle, allowing the illumination function to be provided without permanently integrating a bulky light source into the tool.
Solution Approach 2:
The lighting device transitions from a static integral design to a dynamic detachable design. The lighting portion can be attached when illumination is needed and removed when not needed, providing flexible illumination without constant bulk.
2Use of energy by moving object
If corded lighting devices are used, then power is supplied, but the devices become cumbersome and require constant repositioning
Solution Approach 1:
The power cord is extracted and removed from the system. The lighting portion is designed to be cordless and portable, eliminating the cumbersome cable that required constant repositioning and restricted maneuverability.
3Illumination intensity
If lighting devices are placed close to the surgical site, then direct illumination is achieved, but the devices may disrupt the surgical field
Solution Approach 1:
The detachable lighting portion can be dynamically positioned and removed. When attached, it provides direct illumination close to the surgical site. When removed, it eliminates disruption to the surgical field, offering flexibility to balance illumination needs with surgical accessibility.
4Volume of moving object
If the lighting device is made compact, then maneuverability is improved, but attachment security may be compromised
Solution Approach 1:
The lighting portion features an asymmetric tapered shape that complements the corresponding tapered cavity in the handle. This asymmetric geometry provides secure attachment through friction and geometric interlocking while maintaining a compact form factor.
Solution Approach 2:
The attachment mechanism utilizes friction-based holding with a tapered interface. The friction parameter is sufficient to secure the compact lighting portion during use, while the tapered geometry allows for easy attachment and detachment without compromising security.

AI summary
A cordless light attachment for an object includes a housing that has a proximal end and a distal end, and an interior cavity that extends from the proximal end to the distal end, forming an opening extending through the housing from the proximal end to the distal end. The device receives therein an object and removably attaches to the object. The device has at least one light source powered by a cordless power source arranged on or within the housing.
