Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual target wakeup times are configured for each wireless device, then communication precision is improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent combines multiple individual target wakeup time configurations into a single group-based configuration. By assigning a common offset value to all devices in a group relative to a reference time, the system reduces the number of separate scheduling decisions needed while maintaining precise wakeup time control for each device based on its group membership.
Solution Approach 2:
The offset value serves as a universal parameter that can be applied to multiple wireless devices simultaneously. This single parameter configuration achieves what would otherwise require multiple individual configurations, reducing signaling overhead and scheduling complexity while maintaining the ability to precisely control wakeup times across the group.
2Loss of energy
If uniform offset value is applied to all devices in a group, then signaling overhead is reduced, but individual device optimization capability is limited
Solution Approach 1:
The patent segments wireless devices into distinct groups, where each group receives a common offset value. This segmentation allows the system to apply uniform optimization at the group level (reducing signaling overhead) while still enabling individual device optimization through group-specific configurations. Each group can be optimized independently based on its communication patterns and requirements.
3Reliability
If frequent wakeup checks are performed, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic wakeup behavior by configuring target wakeup times using offset values from a reference time. Devices wake up at predetermined intervals rather than continuously monitoring, achieving reliable communication at scheduled moments while conserving power during idle periods. This periodic action replaces continuous monitoring with efficient scheduled checks.
