Glasses With Replaceable Lenses Using Pivot Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glasses are inconvenient for lens replacement as they require tools or bolts, making the process time-consuming and prone to lens instability, which is not economically advantageous.
Innovation Solution
A pair of glasses with a frame, slot, pivot part, and fastener featuring a fixing groove and elongate holes, allowing the lens to be easily inserted or removed without tools, using a pivot shaft to securely connect and disconnect from the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional glasses use tools or bolts for assembly, then the lenses can be securely fixed, but the lens replacement process becomes time-consuming and inconvenient
Solution Approach 1:
The fastening mechanism is segmented into a fastener body with a fixing groove and a separate pivot shaft that rotates within an elongate hole. This segmentation allows the lens to be quickly secured or released by simply rotating the pivot shaft, eliminating the need for tools or bolts and significantly reducing replacement time.
Solution Approach 2:
The pivot shaft is designed to rotate dynamically within the elongate hole of the fastener. By rotating the pivot shaft between different angular positions, the lens can be quickly transitioned between locked and unlocked states, enabling rapid lens replacement without time-consuming assembly or disassembly operations.
2Device complexity
If conventional glasses use simple assembly methods, then the structure becomes simpler, but the lenses are not securely fixed and may fall off
Solution Approach 1:
The fastening system is divided into distinct components: a fastener with a fixing groove and a pivot shaft with an elongate hole. This simple segmented structure provides reliable lens fixation through the rotational locking mechanism while maintaining structural simplicity and avoiding complex assembly requirements.
Solution Approach 2:
The pivot shaft acts as an intermediary element between the user's manual operation and the lens fixation state. By rotating the pivot shaft within the elongate hole, it mediates the transition between locked and unlocked states, providing reliable lens securing through a simple rotational motion without requiring complex mechanisms.
3Ease of operation
If the fastener is biased upward to extend, then the lens can be easily removed, but the fixing groove separates from the frame and lens
Solution Approach 1:
The fastener is designed with dynamic movement capability through the elongate hole that allows the pivot shaft to extend when the fastener is biased upward. This dynamic design enables easy lens removal by temporarily separating the fixing groove from the frame and lens, while the rotational locking mechanism ensures stable connection during normal use.
Solution Approach 2:
The lens removal process utilizes periodic action through the upward biasing of the fastener that temporarily extends the pivot shaft, separates the fixing groove, and allows lens extraction. This periodic extension and retraction cycle enables easy removal while maintaining stable connection during the majority of the time when the fastener is in its normal positioned state.

AI summary
Provided is a pair of glasses with replaceable lenses, including a frame, having a slot and a pivot part, wherein the pivot part includes at least one pivot hole; a lens, disposed in the slot of the frame; and a fastener, having a fixing groove and at least one elongate hole, wherein a pivot shaft is inserted within the at least elongate hole and the at least one pivot hole, so that the fastener is pivotally connected to the frame. When the frame and the top of the lens are disposed in the fixing groove of the fastener, the lens is buckled. Conversely, when the fastener is biased upward, the fastener is extended the length of by the elongate hole; the fixing groove of the fastener is separated from the frame and the lens, so that the lens can be taken out of the frame.
