Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless transmission is implemented, then cable-free interconnection and flexibility are improved, but transmission quality and stability deteriorate due to interference
Solution Approach 1:
The patent uses RF shields and filters as intermediary components to block electromagnetic interference from reaching the wireless transmission path. These shields act as mediators between the interference sources and the transmission system, preventing harmful signals from degrading the wireless connection quality while maintaining cable-free operation.
Solution Approach 2:
The patent converts the harmful effect of electromagnetic interference into a beneficial filtering mechanism. By strategically placing RF shields and filters, the system uses the presence of interference to drive the development of more effective shielding and filtering solutions, ultimately improving transmission reliability through these protective measures.
2Adaptability or versatility
If integrated transmitters and receivers are added to devices, then interconnection capability is improved, but device complexity increases
Solution Approach 1:
The patent implements universal RF transmitter and receiver modules that can be integrated into multiple types of consumer electronics devices. These multi-functional modules enable different devices (televisions, audio equipment, computing devices) to interconnect wirelessly using the same standardized interface, reducing the need for device-specific customization and managing complexity through standardization.
Solution Approach 2:
The patent combines the RF transmitter and receiver functionality into integrated modules that can be added to existing devices without requiring complete redesign. By merging these wireless communication capabilities with standard device architectures and using common power and signal interfaces, the system reduces overall complexity compared to implementing separate wireless systems for each device type.
3Object-affected harmful factors
If RF shields and filters are installed, then interference resistance is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent divides the interference protection system into separate, modular RF shields and filters that can be manufactured independently and then assembled into the final device. This segmentation allows each component to be optimized and manufactured using specialized processes, then integrated into the device through standardized mounting procedures, reducing overall manufacturing complexity despite adding protection capabilities.
