Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fluorescent lamps are used for illumination, then illumination can be provided in the display chamber, but the lamps require frequent replacement due to aged deterioration and cannot withstand frequent turning on/off
Solution Approach 1:
The patent changes the fundamental parameter of the illumination source from fluorescent lamps to LED illumination apparatuses. LEDs have inherent properties of long lifespan, resistance to frequent switching, and stability in low-temperature environments, directly resolving the reliability and duration issues without requiring additional protective mechanisms.
2Illumination intensity
If fluorescent lamps are used, then illumination is provided, but mercury content makes disposal difficult and requires special handling
Solution Approach 1:
The patent replaces fluorescent lamps containing hazardous mercury with LED illumination apparatuses that are environmentally friendly and do not contain toxic substances. This eliminates the harmful factor of mercury pollution while maintaining illumination capability, and the LED units can be disposed of through normal waste channels without special handling requirements.
3Ease of operation
If fluorescent lamps are frequently turned on/off to match customer presence, then illumination control is achieved, but the lamp life shortens and stable illumination cannot be performed
Solution Approach 1:
The patent changes the illumination source to LEDs, which have the inherent capability to withstand frequent switching operations without degradation. This allows the system to frequently adjust illumination based on customer presence detection while maintaining both lamp life and illumination stability, something impossible with fluorescent lamps.
4Illumination intensity
If fluorescent lamps are used in low-temperature display chambers, then illumination is provided, but the lamps require time to reach predetermined illumination intensity
Solution Approach 1:
The patent replaces fluorescent lamps with LED illumination apparatuses that provide instant full brightness output regardless of ambient temperature. LEDs do not require warm-up time to reach operating temperature and maintain consistent illumination intensity immediately upon activation, eliminating the time loss associated with fluorescent lamp warm-up in cold environments.
5Adaptability or versatility
If multiple showcases are controlled independently, then each showcase can be optimized, but the system complexity increases
Solution Approach 1:
The patent implements a centralized control apparatus that manages multiple LED illumination apparatuses across multiple showcases through a unified system. This multi-functional control unit can independently adjust illumination in each showcase while maintaining a single system architecture, reducing complexity compared to completely independent control systems for each showcase.
Solution Approach 2:
The patent incorporates detection means that monitor customer presence and provide feedback to the control apparatus. This feedback mechanism enables automatic adjustment of illumination levels in response to detected conditions, allowing individual showcase optimization without requiring manual intervention or complex independent control systems for each unit.
