Replaceable Lens Glasses With Spring Clamping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glasses with replaceable lenses are cumbersome and time-consuming to change, especially for active individuals, as they often require tools for lens replacement due to accidental damage or breakage, and existing solutions like elastic rubber rings lose elasticity at low temperatures.
Innovation Solution
The design features a glasses frame with an insertion groove and clamping piece that uses a spring positioning bead and clamping groove for an elastic clamping fit, allowing for easy detachment and wider application range without relying on elastic rubber rings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional elastic rubber rings are used for lens replacement, then the lens can be held in place, but the rubber ring loses elasticity at low temperatures and becomes difficult to operate
Solution Approach 1:
The patent replaces the elastic rubber ring mechanism with a mechanical clamping system consisting of a clamping piece with a spring and a clamping groove. The spring provides constant clamping force through mechanical means rather than relying on temperature-dependent rubber elasticity, ensuring reliable operation across different temperatures.
Solution Approach 2:
The patent changes the physical state and properties of the clamping mechanism from elastic material (rubber) to mechanical components (spring-loaded clamping piece). The spring maintains constant force through its mechanical properties, making the clamping force independent of temperature variations that affect rubber elasticity.
2Reliability
If tools are required for lens replacement, then the lens can be securely held, but the replacement process becomes cumbersome and time-consuming
Solution Approach 1:
The clamping piece is designed to be manually operable without requiring external tools. The user can directly press or manipulate the clamping piece to release the clamping groove, allowing the lens to be removed and installed by hand. This self-service mechanism eliminates the need for screwdrivers or other tools, reducing replacement time while maintaining secure fixation.
3Reliability
If a firm clamping fit is used to prevent accidental detachment, then the lens remains securely in place, but the lens becomes difficult to remove when replacement is needed
Solution Approach 1:
The clamping system transitions from a static interference fit to a dynamic spring-loaded mechanism. The spring allows the clamping piece to flex and release when force is applied, enabling easy removal. During normal use, the spring maintains strong clamping force; during replacement, the user can overcome this force to release the clamp, providing both security and ease of removal.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution provides a simple, convenient method for replacing lenses, ensuring a firm fix that is not easily detached and remains effective across varying temperatures, improving usability and durability compared to traditional methods.
Implementation Method 1
the spring positioning bead on the clamping piece is firstly pressed towards the inside of the housing by the side wall of the insertion end, then the insertion end continues to be fit with the insertion groove, the clamping groove moves to a position corresponding to the spherical surface of the spring positioning bead, and the spring positioning bead extends into the clamping groove under the action of the spring, so as to realize elastic clamping fit
