Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless connection is used to avoid complex cabling, then ease of operation is improved, but communication interference increases
Solution Approach 1:
The patent applies dynamics by making the time-frequency resource configuration adjustable and adaptive. The system dynamically determines resource offsets based on detected interference conditions, allowing the wireless connection to adapt its characteristics in real-time to avoid interference while maintaining the simplicity of wireless connectivity.
Solution Approach 2:
The patent changes parameters by adjusting time-domain and frequency-domain resource offsets to relocate transmission resources away from interfering channels. This parameter modification enables the system to maintain wireless connection simplicity while eliminating communication interference through mathematical resource reallocation.
2Device complexity
If time-frequency resources are shared in congested areas, then device complexity is reduced, but transmission reliability deteriorates
Solution Approach 1:
The patent implements feedback by detecting interference conditions on shared time-frequency resources and using this information to determine appropriate resource offsets. This feedback mechanism enables reliable transmission on congested channels without requiring complex resource management, as the system automatically adjusts based on real-time interference detection.
Solution Approach 2:
The patent introduces an intermediary approach by using resource offset configuration as a mediator between the simple shared resource structure and the need for reliable transmission. The offset mechanism acts as a mediator that translates interference conditions into actionable resource reallocation, maintaining simplicity while ensuring reliability.
3Reliability
If resource offset is applied to eliminate interference, then transmission quality is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the time-frequency resource into discrete units that can be independently offset. This segmentation allows the system to manage complexity through modular resource allocation while improving transmission quality, as each segmented resource can be independently optimized based on interference conditions.
Solution Approach 2:
The patent implements preliminary action by pre-configuring resource offset mechanisms before interference occurs. The system establishes offset capabilities in advance, allowing quick response to interference conditions without requiring complex real-time computation, thus improving transmission quality while limiting complexity increase to pre-established parameters.
