Flexible Eyeglass Temples for Stable Fit Across Head Shapes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses often fail to accommodate diverse head and face shapes, leading to sliding or falling off the user's face, necessitating manual adjustments.
Innovation Solution
The eyeglasses feature flexible temples that can be converted between outwardly and inwardly curved states, allowing better conformance to the user's head shape by manually adjusting the temple distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional eyeglasses with rigid temples are used, then the structure is simple and easy to manufacture, but the eyeglasses cannot adapt to diverse head and face shapes, causing sliding or falling off
Solution Approach 1:
The temple is designed with a flexible section that allows dynamic adjustment between different curved states (first curved state and second curved state), enabling the eyeglasses to adapt to various head and face shapes. This dynamic flexibility resolves the contradiction by allowing the rigid structure to become adaptable without requiring multiple different eyeglass pairs.
Solution Approach 2:
The temple's curvature parameter can be changed between two distinct states through lateral forces applied to the temple tips. This parameter change capability allows the same temple structure to accommodate different head sizes and shapes, improving adaptability while maintaining a single unified structure rather than requiring multiple variants.
2Adaptability or versatility
If the temples are made flexible to convert between curved states, then adaptability improves, but the manufacturing precision requirements increase
Solution Approach 1:
Only a specific section of the temple is designed to be flexible rather than the entire temple. This localized flexibility reduces the manufacturing precision requirements compared to making the whole temple flexible, while still achieving the desired adaptability through the flexible section's ability to transition between curved states.
3Adaptability or versatility
If manual adjustment of the eyeglasses is required, then adaptability can be achieved, but the ease of operation deteriorates due to frequent adjustments needed
Solution Approach 1:
The temple is pre-designed with two specific curved states that are optimized for different head and face shapes. Users can switch between these pre-configured states rather than making continuous manual adjustments, improving ease of operation while maintaining adaptability to diverse head shapes.
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
Prevents sliding and wobbling, enabling stable wear by adapting to individual head shapes.
Implementation Method 1
Each of the two temples have a section that is flexible so that, by applying lateral forces to the two temples, the temples are convertible between an outwardly curved state and an inwardly curved state

AI summary
The eyeglasses includes a glasses frame and two temples. The glasses frame has two opposite ends. Each of the two temples has a front end connected pivotally to a respective one of the two opposite ends of the glasses frame. Each of the two temples have a section that is flexible so that, by applying lateral forces to the two temples, the temples are convertible between an outwardly curved state where rear ends of the two temples are spaced apart from each other at a first distance, and an inwardly curved state where the rear ends of the two temples are spaced apart from each other at a second distance that is smaller than the first distance.
