Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation is achieved through the housing material, then heat dissipation function is provided, but it affects circuit layout and antenna performance
Solution Approach 1:
The housing is segmented into multiple functional regions: sound outlet holes for heat dissipation, first and second through holes for heat conductor passage, and separate accommodation spaces for speaker and heating element. This segmentation allows heat dissipation functionality to be integrated without compromising circuit layout or antenna performance in other regions.
Solution Approach 2:
The housing serves multiple functions simultaneously: it acts as the speaker box structure, provides heat dissipation pathways through integrated heat conductors, supports the speaker unit and heating element, and maintains acoustic isolation between front and back cavities. This multi-functionality eliminates the need for separate heat dissipation components that would complicate circuit layout.
2Temperature
If a heat conductor is introduced to transfer heat from heating element to front cavity, then heat dissipation efficiency is improved, but device structure becomes more complex
Solution Approach 1:
The heat conductor is merged with the housing structure itself, forming an integrated thermal management system. The first heat conductor includes a heat conductive part embedded in the housing and covering the first through hole, and a heat conductive part extending from the heat conductive part of front cavity and covering the second through hole. This integration eliminates separate heat dissipation components and simplifies the overall device structure.
Solution Approach 2:
The heat conductor acts as an intermediary element that bridges the heating element and the front cavity, enabling efficient heat transfer without direct contact between these components. The extensional heat conductive part extending from the housing serves as the interface between the internal heat conductor and the external second heat conductor, facilitating heat transfer while maintaining structural integrity.
