Eyeglass Temple With Twistable Adjusting Pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses tend to separate from the user during movement, such as jogging, due to their design.
Innovation Solution
The eyeglasses feature a frame with pivoting portions and temples that are pivotable between folded and unfolded positions, equipped with a flexible clipping arm and adjusting pad, allowing the temples to securely attach to the frame without detaching, using a positioning pillar, fixing portion, and twistable adjusting pad for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional temples are used with simple pivoting connection, then the structure is simple and easy to manufacture, but the eyeglasses easily separate from the user during movement
Solution Approach 1:
The temple is divided into multiple functional segments: pivoting arm, clipping arm, positioning pillar, fixing portion, and adjusting pad. Each segment performs a specific function to collectively enhance attachment stability while maintaining reasonable structural complexity
Solution Approach 2:
The temple incorporates dynamic elements including the pivotable connection between pivoting arm and frame, the twistable adjusting pad, and the flexible clipping arm. These dynamic features allow the temple to adapt to user movement and maintain secure attachment during activities like jogging
2Ease of operation
If the clipping arm is made flexible and twistable, then the adjustment and comfort are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The clipping arm utilizes material parameter changes - specifically using flexible materials that can be twisted and deformed. The adjusting pad can be rotated within a controlled angle range (smaller than 60 degrees) to provide adjustment while maintaining manufacturing feasibility through standard precision tolerances
3Manufacturing precision
If the adjusting pad twisting angle is limited to smaller than 60 degrees, then the manufacturing precision is controlled, but the adjustment range is reduced
Solution Approach 1:
The patent specifies a twisting angle parameter of smaller than 60 degrees for the adjusting pad. This parameter choice balances manufacturing precision requirements with sufficient adjustment range for most users, providing a practical compromise between precision control and functional versatility
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
The design prevents the eyeglasses from separating from the user by providing a non-detachable connection between the pivoting and clipping arms, ensuring secure wear and easy adjustment for comfort and stability.
Implementation Method 1
a flexible clipping arm integrally formed on the pivoting arm
Implementation Method 2
the adjusting pad is twistable with respect to the pivoting arm by taking the positioning pillar to be a fulcrum

AI summary
A pair of eyeglasses comprises a frame, a lens unit fixed in the frame, and two temples pivotally connected to the frame. Each temple includes a pivoting arm pivotally connected to the frame and a flexible clipping arm integrally formed on the pivoting arm. The pivoting arm has a thru-hole. The clipping arm has a positioning pillar, a fixing portion integrally extended from one end of the positioning pillar, and an adjusting pad integrally extended from another end of the positioning pillar. The positioning pillar couples the thru-hole of the pivoting arm, the fixing portion is fixed on the outer surface of the pivoting arm, and the adjusting pad is arranged proximate to the inner surface of the pivoting arm. The adjusting pad is twistable with respect to the pivoting arm inside 60 degrees.
