Circular Lighting Attachment for Magnifying Lenses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held magnifying lenses or loupes with built-in lights are difficult to replace when malfunctioning, and existing removable light attachments only provide light from one side, not a complete circle around the lens or loupe.
Innovation Solution
A circular lighting attachment with a casing, flexible PCB, LEDs, rechargeable batteries, capacitive touch control, and a light guide that can be easily attached and detached, providing white and UV lighting around the magnifying lens or loupe with a diffused circular light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lights are built-in to hand-held magnifying lens or loupes, then lighting function is integrated, but replacement becomes difficult and cost increases
Solution Approach 1:
The lighting attachment is designed as a separate, detachable module that can be independently removed and replaced. The attachment includes a casing with an annular flange that interfaces with the magnifying lens or loupe, allowing the lighting component to be segmented from the main device. This enables easy replacement of the lighting attachment without replacing the entire magnifying lens or loupe.
2Ease of repair
If light attachment is removable, then replacement becomes easy, but light coverage becomes incomplete (only one side)
Solution Approach 1:
The lighting attachment transitions from providing light from a single direction to providing complete circular light coverage by arranging LEDs along the annular flange perimeter. The flexible PCB is configured to extend around the periphery of the inner wall, enabling LEDs to emit light from all directions around the lens or loupe, achieving complete 360-degree illumination while maintaining removability.
3Illumination intensity
If complete circular light coverage is provided, then illumination completeness improves, but device complexity increases
Solution Approach 1:
A flexible PCB is used to mount the LEDs along the annular flange perimeter. The flexible PCB can be bent and shaped to conform to the circular geometry, allowing multiple LEDs to be arranged in a complete circle without requiring complex rigid structural support. This simplifies the overall device complexity while achieving complete circular light coverage.
Solution Approach 2:
The annular flange serves multiple functions: it provides the structural base for mounting the flexible PCB and LEDs, enables detachable connection to the magnifying lens or loupe, and defines the circular geometry for complete light coverage. This multi-functionality reduces the need for additional separate components, thereby reducing device complexity.
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
Enables convenient and complete circular lighting around the lens or loupe, reducing the need for frequent replacements and providing versatile lighting options with user interface information.
Implementation Method 1
a light guide securely mounted on a top end of the casing which is opposite to the base of the casing to diffuse light emitted from the LEDs
Implementation Method 2
The control means is in form of a capacitive touch control panel
Implementation Method 3
At least one magnet is securely mounted near the charging contact element so as to hold a metallic charging plug in place against the charging contact element
