Adjustable Ancillary Frame for Eyeglasses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses with ancillary frames for protection against ultraviolet rays, snow, dust, or debris lack adjustability, leading to discomfort and improper fit due to differences in face shape, nose height, and diopter, resulting in suboptimal viewing distance and clarity.
Innovation Solution
An eyeglasses assembling structure featuring a main frame, an adjustable ancillary frame, a connecting part with engaging slots, an adjusting element with protrusions, and an engaging part that allows for height, distance, and angle adjustments to accommodate individual needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ancillary frame is fixed in position on the main frame, then the structure is simple and stable, but it cannot accommodate different wearers' face shapes, nose heights, and diopter needs
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed ancillary frame into an adjustable one. The connecting part includes multiple engaging slots positioned at different locations, and the adjusting element can engage with different slots to change the position of the ancillary frame relative to the main frame. This allows the structure to adapt to different wearers' needs while maintaining a relatively simple overall design.
Solution Approach 2:
The patent segments the connecting part into multiple engaging slots and divides the adjusting element into distinct components (engaging portion and positioning portion). This segmentation allows independent adjustment of the ancillary frame's position and angle, enabling customization for different wearers without complicating the entire structure.
2Ease of operation
If the ancillary frame is made adjustable for different wearers, then adaptability improves, but the structure becomes more complex
Solution Approach 1:
The patent merges the adjusting mechanism into the existing connecting part structure. The engaging slots are integrated into the connecting part, and the adjusting element combines both engagement and positioning functions in a single component. This merging approach provides adjustability without significantly increasing the number of separate components.
Solution Approach 2:
The connecting part serves multiple functions: it connects the ancillary frame to the main frame, provides adjustment through engaging slots, and enables angular adjustment through the orientation part. This multi-functionality reduces the need for separate adjustment mechanisms, maintaining simplicity while achieving ease of operation.
3Reliability
If magnets are used to combine the main frame and secondary frame, then assembly is simple, but the frames become loose after extended use
Solution Approach 1:
The patent introduces an intermediate mechanical engagement system (engaging slots and adjusting element) between the main frame and ancillary frame. This intermediary mechanism provides a more reliable connection than direct magnetic attachment, preventing looseness while still maintaining relatively simple assembly through the engaging and disengaging of slots.
