Solution Overview

Problem

Current artificial weathering and light fastness testing devices lack the ability to distinguish between radiation sources of different origins and quality, leading to potential inferior performance and lack of information on the source's history, which can result in premature degradation or failure.

Innovation Solution

Incorporating a storage device, such as an RFID chip, to store and retrieve data about the radiation source's origin, history, and usage, allowing for authorization and identification, ensuring only authorized and high-quality sources are used, and providing information to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If radiation sources of different origins and qualities are used in weathering test devices, then device complexity and ease of operation are improved through flexibility, but reliability deteriorates due to inconsistent spectral quality and premature failure

Engineering Contradiction:
Improveflexibility in radiation source selectionVSAvoidconsistent spectral quality
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements an RFID reading device that reads identification data from radiation sources and provides feedback to a control unit. The control unit monitors operating hours and spectral quality, and can issue warnings or shut down the system when degradation is detected, ensuring consistent performance throughout the radiation source lifecycle

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The radiation sources are equipped with RFID chips that automatically store and transmit their own identification and operational data. The system self-monitors the radiation source status without requiring external intervention, tracking operating hours and detecting quality degradation autonomously

Inventive Principle:
Principle #25Self-service

2Productivity

If radiation sources are operated under high intensity for accelerated aging testing, then productivity is improved through faster testing, but reliability deteriorates due to increased stress and premature failure

Engineering Contradiction:
Improveaccelerated aging testing speedVSAvoidradiation source lifespan
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The control unit continuously monitors operating hours stored in the RFID chip and provides feedback on the remaining service life of the radiation source. This allows operators to optimize testing intensity and schedule maintenance before failure occurs, maintaining high productivity while extending reliable operation

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary monitoring of radiation source status through RFID reading before failure occurs. By tracking operating hours and detecting early signs of degradation, the system can take preventive actions to extend the reliable service life of radiation sources under high-intensity operation

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If no identification system is used for radiation sources, then device complexity is reduced, but loss of information occurs regarding source history and operating hours

Engineering Contradiction:
Improvesystem simplicityVSAvoidradiation source history
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent replaces manual tracking and mechanical identification methods with an electronic RFID system. The RFID chips store detailed information about radiation sources electronically, and the reading device automatically retrieves this data, eliminating information loss while adding minimal complexity through electronic rather than mechanical means

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
