Solution Overview

Problem

Existing eyewear systems fail to adapt their optical properties dynamically to changing environments, leading to inconveniences such as excessive dimming indoors or inadequate correction outdoors.

Innovation Solution

An eyewear system with electrically controlled lenses that includes a sensing section to detect environmental conditions and a control section to switch between modes where optical properties can be changed or fixed, based on user input or environmental data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the dimming function is always maintained, then the optical property is continuously adjusted, but the field of vision is blocked indoors due to excessive dimming

Engineering Contradiction:
Improveadaptability to different environmentsVSAvoidconvenience of use
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements dynamic mode switching between automatic and manual control based on environmental conditions. The control section automatically transitions between modes depending on whether the environment is outdoor (high light intensity) or indoor (low light intensity), making the system adaptive rather than static. This resolves the contradiction by enabling the dimming function to be dynamic and context-aware.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sensing section continuously monitors light intensity and provides feedback to the control section, which then adjusts the optical module accordingly. This feedback mechanism enables automatic mode switching and dimming control, allowing the system to adapt to changing environments without user intervention, thus improving adaptability while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the eyesight correction function is always on, then the optical property is continuously adjusted, but the system cannot adapt when correction is not needed

Engineering Contradiction:
Improveenvironmental adaptabilityVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by stationary object

Solution Approach 1:

The patent implements dynamic switching between automatic and manual modes based on environmental conditions. The control section determines whether to activate eyesight correction functionality based on sensed environmental parameters, enabling the system to adaptively enable or disable correction features. This resolves the contradiction by making the correction function dynamic rather than continuously active.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies different control strategies to different optical properties based on local environmental conditions. The control section independently manages dimming and eyesight correction functions according to specific environmental parameters, allowing selective activation of correction features only when and where needed, thus optimizing energy consumption while maintaining adaptability.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the optical property is continuously changeable, then the system responds to environmental changes, but the system lacks stability when fixed properties are needed

Engineering Contradiction:
Improveresponsiveness to environmentVSAvoidstability of optical properties
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent implements dynamic mode switching between automatic and manual control based on environmental conditions. The control section transitions between modes depending on whether the environment is outdoor (high light intensity) or indoor (low light intensity), making the system adaptive rather than static. This resolves the contradiction by enabling the dimming function to be dynamic and context-aware.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control section periodically evaluates environmental conditions through the sensing section and switches between automatic and manual modes based on predetermined thresholds. This periodic assessment ensures the system maintains stability during appropriate modes while remaining responsive to significant environmental changes, balancing adaptability with stability.

Inventive Principle:
Principle #19Periodic action

AI summary

Eyewear having: a frame; an optical module held by the frame and changing optical properties by electric control; a sensing unit that obtains information pertaining to a usage environment; and a control unit that, on the basis of the information obtained by the sensing unit, changes the optical properties of the optical module. The control unit switches between a mode in which optical properties of can be changed and a mode in which optical properties cannot be changed, on the basis of the information obtained by the sensing unit, and changes the optical properties of the optical module when in the mode in which optical properties can be changed. As a result, eyewear is provided that can switch between modes that change or do not change optical properties, in accordance with the usage environment.
