Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of electronic modules is increased to achieve high functionality, then the functionality of the electronic device is improved, but the space available for mounting modules is reduced
Solution Approach 1:
The antenna module utilizes the non-display area of the display module, transitioning from traditional side-mounted or top-mounted antenna locations to the front surface non-display region. This dimensional repositioning allows the antenna to occupy space that would otherwise be unused, enabling high functionality without compromising mounting space in the traditional module areas.
Solution Approach 2:
The non-display area of the display module serves dual purposes: it maintains its structural and aesthetic function as part of the display assembly while simultaneously housing the antenna module for wireless communication. This multi-functionality allows the same space to contribute to both display integrity and communication capability.
2Area of stationary object
If the antenna module is mounted in the display module to minimize space, then the mounting space is reduced, but the reliability of wireless communication may be compromised due to potential interference with display elements
Solution Approach 1:
The antenna is specifically positioned in the non-display area where display elements are absent, creating a local zone free from electromagnetic interference. This localized placement ensures that the antenna operates in a clean electromagnetic environment while the display elements in other areas remain unaffected, thus maintaining both space efficiency and communication reliability.
Solution Approach 2:
The signal transmission pattern acts as an intermediary between the antenna and the signal radiation pattern, facilitating controlled signal flow and reducing potential interference. This intermediate layer helps isolate the antenna from other electronic components, ensuring reliable wireless communication while maintaining compact integration.
3Reliability
If the opening length is optimized to correspond to the wavelength for improved signal radiation, then the wireless communication reliability is improved, but the design complexity increases
Solution Approach 1:
The opening length of the antenna is specifically designed to correspond to the wavelength of the antenna signal (either λ or λ/2), optimizing the radiation efficiency and signal strength. This parameter optimization ensures reliable wireless communication while maintaining a simple geometric structure that does not significantly increase manufacturing complexity.
