Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If krypton-85 is encapsulated in the internal space of the luminous tube to enhance starting performance, then the discharge lamp shows better starting performance, but adverse effects on environment are concerned in disposal of such a discharge lamp
Solution Approach 1:
The patent extracts and removes the harmful substance (krypton-85) from the discharge lamp system while maintaining the desired function (starting performance) through alternative means. The discharge lamp is designed to operate without encapsulating radioactive krypton-85 in the luminous tube, thereby eliminating environmental disposal issues while achieving reliable starting performance through other technical approaches.
Solution Approach 2:
The patent converts the harmful effect of requiring high voltage and frequency power supplies (which cause malfunctions of surrounding machines) into a benefit by developing discharge lamps that can start with lower voltage and frequency. This is achieved through ingenious techniques that enhance starting performance without krypton-85, transforming a harmful situation into a beneficial one where environmental safety and operational reliability are both improved.
2Reliability
If a power supply device applying large voltage at high frequency is used to cause dielectric breakdown between electrodes, then glow discharge can be started, but the high frequency generated has possibility of inducing malfunctions of surrounding machines
Solution Approach 1:
The patent changes the operational parameters of the discharge lamp system to achieve starting performance without requiring large voltage and high frequency power supplies. By modifying the discharge characteristics and starting conditions, the system can initiate glow discharge with lower voltage and frequency parameters, thereby eliminating harmful high frequency interference to surrounding machines while maintaining reliable starting performance.
3Object-affected harmful factors
If discharge lamps without krypton-85 encapsulation are used to avoid environmental adverse effects, then environmental safety is improved, but starting performance issues occur
Solution Approach 1:
The patent transforms the apparent disadvantage of reduced starting performance in krypton-85-free lamps into a benefit by developing ingenious techniques that enhance starting performance through alternative mechanisms. These techniques enable discharge lamps without radioactive encapsulation to achieve reliable starting performance, simultaneously improving environmental safety and operational reliability.
Solution Approach 2:
The patent modifies the operational parameters and starting conditions of discharge lamps to achieve reliable starting performance without krypton-85 encapsulation. By changing the discharge characteristics, voltage parameters, and starting sequences, the system maintains environmental safety while resolving the starting performance issues that would otherwise occur in krypton-85-free lamps.
4Object-affected harmful factors
If genuine discharge lamps without krypton-85 encapsulation are used, then environmental safety is improved, but non-genuine discharge lamps with krypton-85 encapsulation may be mixed with genuine ones
Solution Approach 1:
The patent employs visual identification methods to distinguish genuine discharge lamps without krypton-85 encapsulation from non-genuine ones with encapsulation. This may involve color-coded markers, labeling systems, or visual characteristics of the lamp structure that allow easy differentiation. The identification method enables accurate sorting and prevention of mixing, ensuring that only environmentally safe genuine lamps are used while maintaining high measurement precision in distinguishing authenticity.
