Adjustable Eyewear Temple with Interlocking Pivot Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyewear tends to fall off during exercise due to a fixed angle defined by the bent earpieces, which does not accommodate varying user needs.
Innovation Solution
The eyewear features adjustable temples with a front segment, a rear segment, and a pivot connector, where the rear segment is prevented from pivoting when a concave corner section engages a convex corner section, allowing the included angle between the segments to be adjusted among multiple positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the temples have a fixed angle defined by bent earpieces, then the structure is simple and stable, but the eyewear falls off during exercise due to inability to adapt to different ear shapes and movement conditions
Solution Approach 1:
The temple is divided into a front segment and a rear segment that can pivot relative to each other. The front segment includes a front portion and a bent earpiece, while the rear segment includes a rear portion. This segmentation allows the temple to be adjusted to different angles to adapt to various ear shapes and exercise conditions, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The temple transitions from a fixed static structure to a dynamic adjustable structure through the pivot connection between the front segment and rear segment. This allows the temple angle to be changed according to different wearing needs, improving adaptability while maintaining reasonable structural complexity through the use of a simple pivot mechanism.
2Adaptability or versatility
If the temples are made adjustable with multiple segments and pivot connectors, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The temple is segmented into functional portions (front portion, bent earpiece, rear portion) that can move independently while remaining connected through the pivot connector. This segmentation enables angle adjustment without requiring complete disassembly, balancing adjustability with structural simplicity.
Solution Approach 2:
A pivot connector serves as an intermediary element between the front segment and rear segment, enabling relative pivoting motion while maintaining structural integrity. This single intermediary component achieves the desired adjustability without requiring multiple complex mechanisms.
3Reliability
If the bent earpiece angle is fixed, then the manufacturing process is simple, but the eyewear cannot maintain secure fit during physical activities
Solution Approach 1:
The temple incorporates a dynamic pivot joint that allows the rear segment to pivot relative to the front segment. This dynamic feature enables the earpiece angle to be adjusted for optimal fit during different activities, improving reliability while the pivot mechanism itself remains simple to manufacture.
Solution Approach 2:
The temple angle parameter can be changed by pivoting the rear segment to different angular positions relative to the front segment. This parameter adjustment capability allows optimization of the fit for different ear shapes and exercise conditions without complex manufacturing processes, as the pivot connection enables easy angular adjustment.

AI summary
A temple unit for an eyewear includes two temples each including pivotally connected front and rear segments. The front and rear segments respectively include adjacent rear and front ends. One of the front and rear ends is formed with a protruding portion, and the other one of the front and rear ends is formed with a recess portion. The protruding portion has at least three non-coplanar first flat surfaces defining two convex corner sections. Any two adjacent ones of the first flat surfaces are connected to each other to define one of the convex corner sections. The recess portion has at least two non-coplanar second flat surfaces connected to each other to define a concave corner section engaging a selected one of the convex corner sections so as to position the rear segment relative to the front segment.
