Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless LAN devices use Power Saving Protocol (PSP) or Automatic Power Save Delivery (APSD) to reduce power consumption by monitoring the network only once per interval and switching to sleep mode, then power consumption is reduced, but communication quality and responsiveness deteriorate
Solution Approach 1:
The patent applies dynamics by making the IC operation information transfer mechanism adaptive and dynamic. The system dynamically adjusts between full IC operation information transfer and partial/selective transfer based on real-time communication conditions, QoS requirements, and power consumption needs. This dynamic adaptation allows the system to optimize the balance between power saving and communication quality rather than using a fixed sleep/monitor pattern.
2Adaptability or versatility
If real-time applications like VoIP and VOD are implemented in wireless LAN, then communication functionality is enhanced, but the requirement for Quality of Service (QoS) increases system complexity
Solution Approach 1:
The patent applies parameter changes by modifying the IC operation information transfer parameters based on application requirements. Different parameters such as transfer frequency, information granularity, and acknowledgment mechanisms are adjusted according to the specific QoS needs of real-time applications like VoIP and VOD, allowing the system to support diverse applications without requiring completely different system architectures.
3Use of energy by moving object
If the driving frequency and supply voltage of information processing IC are dynamically controlled to reduce power consumption, then power consumption is reduced, but processing speed and communication throughput may deteriorate
Solution Approach 1:
The patent applies preliminary action by establishing IC operation information transfer mechanisms in advance that predict and prepare for processing requirements. The system exchanges operation information about driving frequency and voltage adjustments beforehand, allowing the receiving end to prepare appropriate processing capabilities, thus maintaining processing speed while enabling power-saving mode transitions.
