Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of the electronic device is reduced and the number of mounted components is increased, then the device becomes more compact and feature-rich, but the space available for the speaker structure and connection member is narrowed
Solution Approach 1:
The connection member is designed to extend in the thickness direction (Z-axis) rather than only in the planar direction. By routing the connection member through the thickness of the housing and utilizing the third surface, the design transitions from two-dimensional layout to three-dimensional space utilization, allowing the speaker structure to be compact in the planar view while maintaining adequate connection space through vertical stacking.
Solution Approach 2:
The connection member is positioned such that it is drawn out to the third surface of the housing, effectively nesting the connection pathway within the existing housing volume. The pads are disposed on the second surface and the connection member extends through the housing thickness to reach the third surface, utilizing the internal volume of the housing for the connection pathway rather than requiring additional external space.
2Area of stationary object
If the space for the speaker structure and connection member is increased, then adequate arrangement space is provided, but the speaker hole arrangement becomes poor and sound output is compromised
Solution Approach 1:
By moving the connection member arrangement to the third surface (side surface) of the housing rather than confining it to the second surface, the design creates spatial separation between the speaker structure components and the connection member. This dimensional relocation allows the speaker hole to be optimally positioned on the first surface for sound output while the connection member occupies the side surface, eliminating interference and improving overall arrangement quality.
3Reliability
If the connection member is positioned to connect pads on the second surface, then electrical connection is achieved, but the space required for connection increases the overall arrangement volume
Solution Approach 1:
The connection member is designed to extend in the thickness direction from the second surface through the housing to the third surface. This vertical routing allows the connection member to utilize the Z-axis space within the housing rather than expanding the XY-planar footprint. The electrical connection is maintained through this three-dimensional pathway, achieving reliable pad-to-pad connectivity without increasing the planar arrangement volume.
