Eyeglasses With Swingable Temples And Dynamic Temple Pads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sports sunglasses fail to fit various head shapes securely without slippage or falling, particularly during intense movements in sports like baseball and tennis, due to limitations in temple adjustment and cheekbone pad flexibility.
Innovation Solution
The design includes swingable temples with adjustable temple pads and a flexible frame structure, allowing temples to move inward and outward to accommodate different head shapes, and detachable temple pads for customizable fit, preventing slippage and falling without manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the first temple only rotates around a fixed rotation point, then the structure is simple, but the eyeglasses cannot fit various head shapes securely and slippage occurs
Solution Approach 1:
The temple structure is transformed from a static single-point rotation to a dynamic double-point rotation system. The first temple rotates around a first rotation point near the hinge and a second rotation point near the ear, enabling the temple to adapt to various head shapes while maintaining structural simplicity through controlled degrees of freedom.
Solution Approach 2:
The temple rotation function is segmented into two independent rotation points rather than one fixed point. This segmentation allows different portions of the temple to rotate independently, providing better adaptation to diverse head shapes without significantly increasing overall structural complexity.
2Adaptability or versatility
If the cheekbone pad position is adjustable in the longitudinal direction only, then the structure is simple, but the eyeglasses cannot fit various head shapes and manual adjustment is required
Solution Approach 1:
The cheekbone pad is designed to automatically adjust its position along the temple in the longitudinal direction through the temple's double-point rotation mechanism. When the temple rotates to fit different head shapes, the cheekbone pad moves passively without requiring the wearer to manually loosen or tighten screws, making the system self-adjusting.
Solution Approach 2:
The cheekbone pad adjustment function is merged with the temple rotation function. The cheekbone pad's longitudinal movement is coupled to the temple's rotation around two points, so that a single rotational action simultaneously achieves both temple positioning and cheekbone pad adjustment, eliminating the need for separate manual adjustment operations.
3Reliability
If the first temple placement is at the front, back, or center part of the ear, then the structure is simple, but the fitting feeling changes and slippage occurs during intense movements
Solution Approach 1:
Instead of fixing the first temple at a single static position (front, back, or center of ear), the system uses dynamic double-point rotation that allows the temple to automatically reposition itself during intense movements. This dynamic adaptation maintains reliable fit and prevents slippage without requiring complex adjustable mechanisms.

AI summary
Provided are eyeglasses that can be supported so as to fit each of various head shapes of wearers without any gap, are extremely excellent in preventing slippage and falling during exercise, have a good fitting feeling, and do not particularly require an adjustment operation for preventing slippage and falling. The eyeglasses include a frame, end pieces attached to both end portions of the frame, and temples attached to the back ends of the end pieces so as to be swingable in the inward and outward directions, and a temple pad protrudes from the front end of the temple. The temple pad moves inward when the temple swings outward, and the temple pad moves outward when the temple swings inward.
