Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a speaker is positioned close to surrounding electrical components to save space, then device compactness is improved, but magnetic interference to those components increases
Solution Approach 1:
A metal plate serving as a magnetic shielding intermediary is positioned between the speaker and surrounding electrical components. This plate reflects and redirects magnetic field lines, preventing direct magnetic interference to nearby components while allowing the speaker to maintain close positioning for compact device design.
Solution Approach 2:
The metal plate is divided into multiple regions with different functions: a first region overlapping the speaker for magnetic shielding, and a second region with protrusions for structural support and positioning. This segmentation allows each region to optimize its specific function while working together to solve the overall contradiction.
2Object-affected harmful factors
If a metal plate with magnetic shielding material is added between the speaker and surrounding components, then magnetic interference is reduced, but device complexity increases
Solution Approach 1:
The metal plate performs multiple functions simultaneously: it provides magnetic shielding through its material properties, structural support through its rigid construction, and component positioning through its protrusions. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while effectively reducing magnetic interference.
Solution Approach 2:
The magnetic shielding function, structural support function, and component positioning function are merged into a single metal plate component. This consolidation reduces the number of separate parts needed in the device, minimizing the increase in manufacturing and assembly complexity while achieving effective magnetic interference reduction.
