Eyeglass-Mounted Light Clip With Pivotable Pole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination devices for medical professionals, such as headlamps and flashlight-attached eyeglasses, often create unwanted shadows due to the light source being positioned too far from the user's interpupil region, leading to inadequate lighting of the area of interest during medical procedures.
Innovation Solution
A lighting device with a pivotable pole and electric lamp attached to eyeglasses via a releasable fastener, featuring a battery set and conductive assembly for direct power connection, allowing the lamp to be positioned optimally between the user's eyes for improved illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a flashlight is attached to the bridge of eyeglasses, then the light source can be positioned above eye level, but the light projects downward creating large shadows and inadequate lighting of the area of interest
Solution Approach 1:
The patent applies the dynamics principle by making the light source position adjustable and movable rather than fixed. The lighting device includes a flexible arm or positioning mechanism that allows the user to dynamically adjust the light source location and angle, enabling the light to be directed precisely at the area of interest while minimizing shadow formation. This dynamic adjustment capability resolves the contradiction between achieving proper illumination and maintaining ease of operation.
2Illumination intensity
If the light source is positioned far from the user's interpupil region, then the device structure is simpler, but larger shadows are created and the region of interest is not adequately lit
Solution Approach 1:
The patent applies the nesting principle by integrating the light source within or close to the eyeglass frame structure itself, rather than positioning it far away on a separate mount. The lighting device is nested within the eyeglass assembly, with the light source positioned in proximity to the interpupil region through clever use of the existing frame geometry. This nested integration achieves proper lighting quality while minimizing the added device complexity.
3Use of energy by moving object
If a battery pack is worn on the headband, then the light source can be powered, but the device becomes more complex and expensive
Solution Approach 1:
The patent applies the universality principle by designing the eyeglass frame to serve multiple functions: it provides the structural support for the lenses, acts as the mounting structure for the lighting device, and serves as the housing for the battery pack. This multi-functional integration eliminates the need for separate battery compartments or additional structural elements, thereby providing power to the light source while minimizing device complexity and cost.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides focused, shadow-free lighting directly in front of the user's eyes, enhancing visibility during medical procedures by positioning the light source closer to the interpupil region, thereby improving the lighting of the area of interest.
Implementation Method 1
a battery set; and a conductive assembly electrically connected between the battery set and the electric lamp, so as to power the electric lamp

AI summary
A lighting device, for attachment to an object structured to be worn on at least one facial feature of a human user, having a releasable fastener adapted for attachment to the above-noted object and a pole, having a first end pivotably connected to the releasable fastener, and a second end, opposed to the first end. An electric lamp is pivotably connected to the second end. Further, the pole defines an internal cavity and has battery contacts positioned to contact a battery set placed in the internal cavity. A conductive assembly is electrically connected between the battery contacts and the electric lamp, so as to power the electric lamp.
