Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If beam forming technology is used to communicate with multiple peer devices, then power concentration and electricity usage efficiency are improved, but beam interference between peer devices occurs reducing communication quality
Solution Approach 1:
The patent implements a feedback mechanism where the wireless communication device notifies each communication peer device of beam direction information and timing information. Peer devices feed back their beam usage status, enabling the system to coordinate beam directions and timing to avoid interference while maintaining power concentration benefits.
Solution Approach 2:
The wireless communication device acts as an intermediary that manages and coordinates beam forming operations among multiple peer devices. It notifies peer devices of beam directions and timing, and receives feedback from them, thereby mediating the resource allocation to prevent interference while maintaining efficient power usage.
2Productivity
If beam direction switching in time division manner is implemented, then communication efficiency with multiple peer devices is improved, but coordination complexity increases
Solution Approach 1:
The wireless communication device performs preliminary actions by notifying each communication peer device of beam direction information and timing information before actual communication occurs. This advance notification allows peer devices to prepare their reception beams in advance, simplifying real-time coordination while maintaining high communication efficiency.
3Adaptability or versatility
If each peer device uses independent beam directions, then communication flexibility is improved, but beam interference between devices increases
Solution Approach 1:
The system maintains communication flexibility by allowing each peer device to use its own beam direction while implementing feedback mechanisms. Each device notifies others of its beam usage, and the system coordinates based on this feedback to prevent interference, thereby preserving adaptability while eliminating harmful effects.
