Solution Overview

Problem

Users often perform activities under non-optimal lighting conditions due to a lack of awareness or control over the lighting environment, which can impact the effectiveness and comfort of tasks such as reading, computing, or watching television.

Innovation Solution

A wearable computing device equipped with optical and activity sensors that determine the actual lighting conditions and user activity, comparing them to suitable conditions and generating signals to adjust the lighting, either manually or automatically, to ensure optimal illumination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users are provided with manual control over lighting conditions, then ease of operation is improved, but productivity deteriorates because users may not consistently adjust lighting to optimal levels

Engineering Contradiction:
Improveuser controlVSAvoidtask effectiveness
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The lighting system automatically monitors user activity and adjusts lighting conditions without requiring manual user intervention. The system serves itself by detecting when lighting adjustments are needed and executing the adjustments autonomously, eliminating the gap between user awareness and actual lighting optimization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors user activity through sensors and provides feedback by automatically adjusting lighting conditions based on detected activity types. This closed-loop feedback mechanism ensures lighting remains optimal for current tasks without requiring users to manually assess or adjust conditions.

Inventive Principle:
Principle #23Feedback

2Productivity

If automated lighting adjustment is implemented, then productivity is improved through optimal lighting, but device complexity increases

Engineering Contradiction:
Improvetask effectivenessVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The wearable device performs multiple functions: it detects user activity types, determines appropriate lighting conditions, controls lighting adjustments, and provides user interface interactions. By consolidating these functions into a single multi-functional device, the system avoids the complexity of coordinating multiple separate systems while achieving automated lighting optimization.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system combines activity sensing, lighting control, and user interface capabilities into an integrated wearable device that works with the lighting system. This merging of functions into a single coordinated system reduces overall system complexity compared to separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

3Illumination intensity

If lighting conditions are continuously monitored and adjusted, then illumination quality is improved, but use of energy increases

Engineering Contradiction:
Improvelighting qualityVSAvoidenergy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The lighting system dynamically adjusts illumination levels based on real-time detection of user activity. Rather than maintaining constant high-level monitoring and adjustment, the system adapts lighting conditions to match actual user needs for different activities, optimizing illumination quality while minimizing energy consumption during periods of inactivity or stable conditions.

Inventive Principle:
Principle #15Dynamics
