Solution Overview

Problem

Conventional UV disinfection systems face inefficiencies due to inconsistent UV lamp degradation, leading to overdriving lamps, increased electricity costs, and premature failures, as they assume uniform degradation across all lamps and fail to account for variable losses in power distribution.

Innovation Solution

Implementing a system where UV lamps can measure their own irradiance and transmittance values, sharing this data with other lamps to adjust their output and maintain a consistent fluence rate, independent of lamp age or connection losses, thereby compensating for underperforming or overperforming lamps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional UV disinfection systems assume uniform degradation across all lamps and overdrive lamps to compensate, then disinfection effectiveness is maintained, but electricity costs increase and lamp lifespan decreases

Engineering Contradiction:
Improvedisinfection effectivenessVSAvoidelectricity cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The system implements feedback by having each lamp measure its own irradiance and transmittance values, share this data with other lamps, and dynamically adjust output based on real-time performance data. This eliminates the need for overdriving lamps to compensate for degradation, as each lamp's actual performance is monitored and used to maintain disinfection effectiveness while optimizing energy consumption.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Each UV lamp performs self-diagnosis by measuring its own irradiance and transmittance values. The lamp autonomously determines its performance status and communicates this information to the system, enabling self-regulation without requiring external monitoring or manual intervention to maintain disinfection effectiveness.

Inventive Principle:
Principle #25Self-service

2Device complexity

If conventional UV disinfection systems assume uniform degradation across all lamps, then system control is simplified, but variable losses in power distribution are not accounted for leading to inefficiencies

Engineering Contradiction:
Improvesystem control complexityVSAvoidpower distribution efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system replaces simplified uniform degradation assumptions with real-time feedback from individual lamp measurements. Each lamp measures its own irradiance and transmittance, and the system uses this specific data to control each lamp's output independently, accounting for variable power distribution losses while maintaining manageable system complexity through automated control.

Inventive Principle:
Principle #23Feedback

3Device complexity

If UV lamps operate without real-time performance monitoring, then system operation is simpler, but lamp failures are not detected early leading to increased downtime

Engineering Contradiction:
Improvemonitoring system complexityVSAvoidlamp downtime
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system implements continuous feedback monitoring where each lamp measures its own irradiance and transmittance values in real-time. This early detection capability allows the system to identify underperforming lamps before complete failure occurs, enabling timely maintenance intervention and reducing overall lamp downtime despite the added monitoring complexity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Each UV lamp autonomously monitors its own performance by measuring irradiance and transmittance values. The lamp self-diagnoses its status and communicates this information to the system, enabling early failure detection without requiring complex external monitoring equipment or manual inspection procedures.

Inventive Principle:
Principle #25Self-service
