Adjustable Loupe with Ball and Socket Joint for Focus Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watch repairers and jewelers face challenges in maintaining focus over time due to factors like strain, fatigue, and fluctuating blood sugar and blood-pressure levels, leading to mental fatigue and headaches when using fixed loupe systems.
Innovation Solution
A loupe apparatus with a support, post, and rotatable lens holder featuring a ball and socket joint, allowing adjustable positioning and magnification, which can be attached to glasses, a headband, or a nose bridge, enabling flexible focus adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed loupe system is used, then the structure is simple and stable, but the user experiences strain and mental fatigue over time due to inability to adjust focus
Solution Approach 1:
The patent implements a dynamic lens holder system with ball and socket joints that allow the lens position to be adjusted in multiple directions. This enables the loupe to adapt to changing user focus needs throughout the day, resolving the contradiction between fixed structure simplicity and user comfort during extended use.
Solution Approach 2:
The patent allows changing the focal parameter by adjusting the lens holder position relative to the lens. Users can modify the distance and angle of the lens from their eye to optimize focus at different times, addressing the inability of fixed systems to adapt to physiological changes.
2Adaptability or versatility
If a fixed loupe system is used, then the device is simple, but it cannot adapt to changing focus ability caused by strain, fatigue, and physiological factors
Solution Approach 1:
The patent employs dynamic joint mechanisms (ball and socket joints) that enable the lens holder to move and be repositioned in multiple degrees of freedom. This provides adaptability to changing focus requirements while maintaining a relatively simple mechanical structure that can be adjusted during use.
3Ease of operation
If an adjustable lens holder with ball and socket joint is used, then focus and magnification can be adjusted for comfort, but the device complexity increases
Solution Approach 1:
The patent divides the lens holder into segmented components connected by ball and socket joints, allowing independent adjustment of different sections. This segmentation enables complex adjustment capabilities while keeping each individual component relatively simple and manageable.
