Eyeglass Frame With Vertically Movable Auxiliary Lenses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglass frames with attachable lenses suffer from instability, visibility obstruction, and complex structures, particularly when using movable lenses, leading to discomfort and eye strain.
Innovation Solution
A pair of movable lens-holding frames with a vertical movement unit, featuring a support shaft and stopper mechanism, allows lenses to move vertically above the fixed frames, maintaining eye level and reducing wobbliness, using a J-shaped or rectangular column structure for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If another pair of lenses is attachable in front of eyeglass lenses, then different types of vision correction can be performed, but the structure becomes complicated
Solution Approach 1:
The patent combines the auxiliary lenses and their holding frame into a single integrated movable lens-holding frame assembly that attaches to the main eyeglass frame. This merging eliminates the need for separate attachment mechanisms and simplifies the overall structure while maintaining the capability to switch between different lens configurations.
Solution Approach 2:
The movable lens-holding frame is designed to accommodate multiple types of lenses (sunglasses, reading glasses, polarized lenses) in a single universal structure. This multi-functional design allows users to switch between different vision correction types without requiring multiple separate attachment mechanisms, thereby reducing structural complexity.
2Adaptability or versatility
If the auxiliary lenses are made vertically movable, then different types of lenses can be used, but the outside of the lenses becomes unstable
Solution Approach 1:
The patent implements a dynamic lens-holding system where the entire lens-holding frame can be vertically moved between a stored position and a use position. This dynamic design allows the lenses to be selectively positioned - stable when in the use position and easily movable when transitioning between states, resolving the contradiction between stability and versatility.
Solution Approach 2:
The movable lens-holding frame acts as an intermediary mechanism between the user's hand and the lenses. It provides a stable mounting structure for the lenses when in position, while allowing controlled vertical movement for switching. The intermediary frame absorbs the movement requirements while maintaining lens stability during use.
3Ease of operation
If the movement mechanism is provided, then vertical movement of lenses is enabled, but the movement mechanism enters the field of view and irritates the wearer
Solution Approach 1:
The patent nests the movement mechanism within the temple arm structure, embedding the vertical movement mechanism inside the temple rather than having it protrude into the field of view. The movement mechanism is concealed within the temple's internal structure, allowing lens adjustment without visual obstruction or wearer irritation.
4Ease of operation
If the slide frame is embedded inside the auxiliary lenses, then vertical movement is achieved, but the outside of the auxiliary lenses becomes unstable
Solution Approach 1:
The patent applies dynamics by making the entire lens-holding frame movable rather than embedding a slide mechanism within the lenses. This allows the lenses to maintain their external stability while the whole assembly can be vertically positioned. The dynamic movement is achieved at the frame level, preserving lens integrity and outer stability.
