Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If holes are made on the housing for heat dissipation, then heat dissipation performance is improved, but electromagnetic interference increases and signal transmission performance deteriorates
Solution Approach 1:
The housing is segmented into multiple functional regions: heat dissipation holes are provided on the first housing for thermal management, while a shielding member divides the second housing into a signal transmission cavity and a heat dissipation cavity. This segmentation allows heat to dissipate through the first housing while electromagnetic signals are contained within the second housing, resolving the contradiction between heat dissipation and EMI shielding.
Solution Approach 2:
A shielding member acts as an intermediary element between the heat dissipation function and the signal transmission function. This shielding member, made of electromagnetic shielding material, physically separates the two functions while allowing thermal energy to pass through the first housing and electromagnetic signals to be contained within the second housing, thus mediating the conflict between heat dissipation and EMI protection.
2Temperature
If holes are made on the housing for heat dissipation, then heat dissipation performance is improved, but signal transmission performance deteriorates
Solution Approach 1:
The housing structure is divided into distinct functional zones: the first housing contains heat dissipation holes for thermal management, while the second housing is partitioned by a shielding member into separate signal transmission and heat dissipation cavities. This spatial segmentation ensures that heat dissipation occurs through the first housing without compromising signal integrity within the second housing.
Solution Approach 2:
The shielding member serves as an intermediary barrier that separates thermal management functions from signal transmission functions. It allows heat to be dissipated while maintaining electromagnetic signal integrity by preventing interference between the two functional regions.
3Reliability
If electromagnetic shielding is implemented to block signal interference, then signal transmission performance is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The housing is segmented into multiple cavities with dedicated functions: the signal transmission cavity is enclosed by the shielding member for EMI protection, while the heat dissipation cavity and first housing provide thermal management pathways. This segmentation allows both functions to operate independently and effectively simultaneously.
Solution Approach 2:
The shielding member acts as an intermediary that enables both electromagnetic shielding and heat dissipation by creating separate functional spaces. The first housing serves as another intermediary element that facilitates heat dissipation while the shielding member protects signals, allowing both functions to coexist without compromising each other.
