Solution Overview

Problem

Eyewear with temples that apply strong pressure on the user's head can be uncomfortable to wear.

Innovation Solution

A frame and eyewear design featuring a connecting part with elasticity that connects the temples and front, with a wiring arranged in the space between, providing a comfortable wearing experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the temples are connected to the front by rigid connections, then the structural strength is improved, but the wearing comfort deteriorates due to strong pressure on the user's head

Engineering Contradiction:

Improvestructural strengthVSAvoidpressure on user's head

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The connecting part changes its physical state from rigid to elastic, allowing it to deform and absorb pressure. This parameter change enables the connection to maintain structural integrity while reducing the harmful pressure effect on the user's head through elastic deformation.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The connecting part is designed as an elastic component that can flex and deform under pressure. This flexibility allows the temples to adjust to the user's head shape while maintaining connection strength, resolving the contradiction between structural rigidity and wearing comfort.

Inventive Principle:

Principle #30Flexible shells and thin films

2Device complexity

If the wiring is arranged outside the front-connecting part space, then the electrical connection is simplified, but the device complexity increases due to additional components needed to protect and route the wiring

Engineering Contradiction:

Improvewiring arrangement complexityVSAvoidelectrical connection reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The wiring is integrated into the existing space between the front and connecting part, merging the electrical connection function with the structural space already present in the design. This eliminates the need for separate wiring channels or protective components, reducing device complexity while maintaining connection reliability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The space between the front and connecting part serves multiple functions: it provides structural connection support and simultaneously houses the wiring for electrical connections. This multi-functionality reduces the need for additional dedicated spaces or components for wiring routing.

Inventive Principle:

Principle #6Universality (Multi-functionality)
