Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the diode array is left exposed in the electrocaloric device, then the device structure remains simple, but the device fails to protect the diode array from high-moisture environments causing characteristic anomalies
Solution Approach 1:
The protective base is merged with the electrocaloric device structure, integrating the protection function into the existing device rather than adding a separate protective component. This reduces overall structural complexity while achieving diode array protection.
Solution Approach 2:
The protective base serves multiple functions: it protects the diode array from moisture, provides structural support, and facilitates heat dissipation. This multi-functionality reduces the need for additional separate components.
2Reliability
If an additional package protection is added to protect the diode array, then the diode array is protected from high-moisture environments, but the overall device size increases making miniaturization difficult
Solution Approach 1:
The protective base is integrated into the electrocaloric device structure rather than being a separate external package, eliminating the need for additional space and enabling miniaturization.
Solution Approach 2:
The diode array is nested within the protective base structure, with the cooling plate positioned between them. This nested arrangement protects the diode array while maintaining a compact overall device size.
3Volume of moving object
If the cooling plate area is reduced to minimize device size, then device miniaturization is achieved, but the cooling efficiency may be compromised
Solution Approach 1:
The cooling plate is positioned directly against the light emitting component which generates the most heat, concentrating cooling capacity where it is most needed rather than uniformly distributing it across a larger area.
Solution Approach 2:
The nested arrangement of the cooling plate within the protective base structure allows for efficient heat transfer in a compact space, maintaining cooling effectiveness while minimizing device size.
