Solution Overview

Problem

In shared spaces, individuals with different lighting preferences often face challenges in accommodating each other's needs for optimal viewing and reading conditions, as existing systems lack the ability to dynamically adjust lighting schemes to suit multiple users' preferences simultaneously.

Innovation Solution

A system that receives and processes light preference profiles from multiple users, determining distinct light control settings and generating periodic light source actuation directives to alternate lighting schemes in synchronization with shutter control directives for near eye apparatuses, ensuring each user experiences their preferred lighting conditions without interfering with others.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single light source illuminates a shared room, then the lighting scheme can be uniformly controlled, but it cannot simultaneously satisfy different lighting preferences of multiple users

Engineering Contradiction:

Improvelighting scheme adaptabilityVSAvoidlighting preference conflict

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The system implements periodic action by time-multiplexing the light source actuation. The controller alternates between first and second light control settings in periodic intervals, synchronized with the shutter glasses switching between translucent and opaque states. This allows the single light source to sequentially provide different lighting schemes that satisfy different users' preferences during different time periods within each cycle.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The shutter glasses serve as an intermediary device between the users and the shared light source. By controlling the translucency state of the shutter glasses, the system enables each user to selectively perceive the light source actuation according to their preferred lighting scheme during specific time periods, thus resolving the lighting preference conflict without requiring multiple independent light sources.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the light source is actuated according to one user's preference, then that user experiences optimal lighting conditions, but the other user experiences suboptimal conditions

Engineering Contradiction:

Improveuser experience qualityVSAvoidmulti-user accommodation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system applies dynamics by making the light source actuation and shutter control dynamically adjustable based on user preferences. The controller receives light preference profiles from multiple users, determines distinct light control settings for each user, and dynamically switches between these settings in synchronization with the shutter glasses. This dynamic adjustment allows the system to adapt to different users' needs while maintaining high ease of operation for each individual.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If multiple light sources are used to satisfy different users' preferences, then each user can have their preferred lighting scheme, but the device complexity increases

Engineering Contradiction:

Improvemulti-preference supportVSAvoidlight source configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The single light source is designed to be universal and multi-functional by capable of operating under multiple distinct light control settings. Rather than requiring separate light sources for each user, the same light source can be actuated in conformance with different light control settings (first light control setting and second light control setting) to satisfy different users' preferences sequentially, thus reducing device complexity while maintaining multi-preference support.

Inventive Principle:

Principle #6Universality (Multi-functionality)
