Eyeglass Temple Auxiliary Cushion Frame for Stable Comfort

Solution Overview

Problem

Conventional eyeglasses suffer from instability when the head clamping force of the temples is too small, leading to unstable wear, and discomfort when it is too large, failing to provide a balance between stability and comfort.

Innovation Solution

An eyeglass temple design featuring a main frame connected to a lens unit and an auxiliary cushion frame with an ear engaging portion, a main connecting portion, an abutment portion, and resilient connecting portions that bias the abutment portion to contact the wearer's head, ensuring stable and comfortable wear.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the head clamping force of the temples is increased to improve stability, then the eyeglasses can be worn more stably on the wearer's head, but discomfort will be caused to the wearer's head

Engineering Contradiction:

Improvestability of eyeglasses on wearer's headVSAvoiddiscomfort to wearer's head

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention applies different material properties to different parts of the temple: the main frame uses rigid material for structural support, while the auxiliary cushion frame uses soft resilient material for comfort. This local differentiation allows the rigid main frame to provide stability while the soft auxiliary cushion reduces discomfort at the contact point with the head.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The temple combines two distinct materials: a rigid material for the main frame and a soft resilient material for the auxiliary cushion frame. This composite structure enables simultaneous achievement of stability (through rigid main frame) and comfort (through soft auxiliary cushion), resolving the contradiction between these two requirements.

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 allows for stable and comfortable wear by providing a balanced head clamping force, preventing both instability and discomfort through the use of a soft material auxiliary cushion frame that biases the abutment portion against the head.

Implementation Method 1

at least one resilient connecting portion connected between the main connecting portion and the abutment portion and adapted for biasing the abutment portion away from the main connecting portion toward the wearer's head

AI summary

An eyeglass temple includes a main frame adapted for connection with a lens unit, and an auxiliary cushion frame disposed behind the main frame. The auxiliary cushion frame includes an ear engaging portion, a main connecting portion extending forwardly from the ear engaging portion to connect with the main connecting portion, an abutment portion extending forwardly from the ear engaging portion and adapted to be disposed between the main connecting portion and the wearer's head, and at least one resilient connecting portion connected between the main connecting portion and the abutment portion and adapted for biasing the abutment portion away from the main connecting portion toward the wearer's head.
