Lens Replaceable Eyeglasses Modular Connector Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglasses require professional assistance for lens replacement, which is inconvenient and time-consuming for users when a lens becomes damaged.
Innovation Solution
A design featuring a front with openings, lugs, and connectors that allow users to easily replace lenses by unscrewing bolts and screws, with a U-shaped chamber and positioning members ensuring secure installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional eyeglasses with fixed lenses are used, then lens security and structural simplicity are improved, but lens replacement convenience deteriorates
Solution Approach 1:
The eyeglass frame is divided into modular components: front, temples, connectors, and positioning members. The lens assembly is separated from the frame through removable connectors, allowing independent replacement of lenses without affecting the overall structure. This segmentation enables users to replace lenses easily while maintaining structural integrity through the modular design.
Solution Approach 2:
The connectors are designed with threaded holes and positioning members that allow dynamic adjustment between secured and removed states. The screws can be rotated to tighten or loosen the connection, providing a transition from a fixed secure state to a removable state, enabling easy lens replacement while ensuring secure attachment during use.
2Manufacturing precision
If professional lens replacement service is used, then lens replacement accuracy is improved, but time consumption and convenience deteriorate
Solution Approach 1:
The positioning members with tubular portions and positioning holes are pre-configured in the connectors and frame respectively. These positioning elements are designed in advance to guide the lens assembly into the correct position during replacement, ensuring accurate alignment without requiring professional tools or expertise. Users can quickly replace lenses with proper positioning while maintaining replacement accuracy.
3Device complexity
If simple screw connection is used, then device complexity is reduced, but lens securing reliability deteriorates
Solution Approach 1:
The connection mechanism merges multiple functions into integrated components: the connectors combine threaded holes for screw attachment with positioning members for alignment, and the positioning members include tubular portions that receive screws while providing positional guidance. This merging of securing and positioning functions into a single integrated mechanism maintains simplicity while ensuring reliable lens attachment.

AI summary
A pair of eyeglasses includes a front with two lenses installed in the two openings thereof. Two lugs respectively extend from two ends of the front and each have a slot communicating with the opening corresponding thereto. Two threaded holes are respectively defined through the two ends of the front and communicate with the two slots. Two screws threadedly extend through the two threaded holes to narrow the slots to secure the two lenses in the front. The two lugs are clamped between the two connectors and two securing members by bolts extending through the securing members, the lugs and the two connectors, and connected with two positioning members. The lenses can be replaced by unscrewing the bolts and the screws.
