Engineering Contradiction Analysis
1Object-affected harmful factors
If a blocking structure is provided to block electromagnetic fields and electromagnetic waves, then electromagnetic interference is reduced, but wireless communication is hindered
Solution Approach 1:
The blocking structure is segmented into a first blocking structure and a second blocking structure positioned at different locations. The wireless communication circuit board is also segmented in its positioning, with the wireless communication unit located between these two blocking structures. This segmentation allows each component to fulfill its function without interfering with others.
Solution Approach 2:
The patent transitions from a two-dimensional planar layout to a three-dimensional spatial arrangement. The wireless communication circuit board is positioned vertically between the first and second blocking structures, utilizing the vertical dimension to achieve both electromagnetic shielding and wireless communication functionality simultaneously.
2Reliability
If the wireless communication circuit board is positioned to avoid blocking structures, then wireless communication is smooth, but electromagnetic shielding is reduced
Solution Approach 1:
The wireless communication unit acts as an intermediary element positioned between the first and second blocking structures. It benefits from the electromagnetic shielding provided by both blocking structures while maintaining its wireless communication functionality, as the blocking structures are positioned to shield without completely obstructing the wireless communication path.
3Device complexity
If metal components are positioned close to the wireless communication circuit board, then device complexity is reduced, but electromagnetic interference increases
Solution Approach 1:
The patent applies local quality by providing blocking structures at specific locations where electromagnetic interference is most likely to occur. The first blocking structure is positioned between the heating element and the wireless communication circuit board, while the second blocking structure is positioned at another critical location. This localized approach provides effective shielding without requiring complete shielding throughout the entire device.
