Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the communication module is designed inside the electrical device, then the device structure is compact, but the communication module is shielded by the metal shell and interfered by other electronic components
Solution Approach 1:
The communication module is separated from the main electrical device body and integrated into the power cord assembly. This segmentation allows the communication module to be positioned outside the metal shell's interference zone while maintaining a compact overall structure through the cord's flexible connection.
Solution Approach 2:
The power cord acts as an intermediary carrier for the communication module. By placing the module in the cord rather than directly in the device housing, the cord serves as a buffer that isolates the sensitive communication components from both the metal shell shielding and internal electronic interference while maintaining structural compactness.
2Ease of operation
If the communication module is designed on the shell of the electrical device, then the communication module is accessible, but the communication ability is influenced by the metal shell and affected by high temperature
Solution Approach 1:
The communication module is extracted from both the device interior and the shell surface, and relocated to the power cord. This extraction removes the module from environments with metal shell shielding and high temperature exposure, while the cord provides a protected pathway that maintains accessibility without compromising communication stability.
Solution Approach 2:
Instead of placing the communication module in the traditional two-dimensional plane of the device shell surface or interior, the module is positioned in a different spatial dimension along the power cord extension. This dimensional relocation allows the module to be outside the harmful electromagnetic and thermal zones while remaining functionally connected.
3Reliability
If the antenna is led out alone and designed at the outside of the electrical device, then the communication module can work outside the device, but the appearance consistency is affected and the device size is increased
Solution Approach 1:
The antenna and communication module are merged into a single integrated assembly that is combined with the power cord. This merging allows the communication components to work together outside the device body without requiring separate external antenna structures, thereby maintaining appearance consistency while ensuring communication functionality.
Solution Approach 2:
The power cord is given multiple functions: it serves both as the power supply connection and as the mounting structure for the communication module and antenna. This multi-functionality eliminates the need for separate external communication components that would compromise appearance, while still providing reliable external communication capability.
4Reliability
If the antenna is mounted at the outside of the electrical device, then the antenna can transmit signals, but the antenna is liable to damage
Solution Approach 1:
The antenna is nested within the power cord assembly rather than being exposed externally. The cord's insulation and structural layers protect the antenna from physical damage, environmental factors, and accidental contact, while the antenna remains positioned to transmit signals effectively for communication functionality.
