Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in efficiently discovering passive IoT devices due to their lack of a power source, limited mobility, and the need for close proximity activation, leading to unpredictable energy consumption and time-consuming discovery processes that can fail due to blockages.
Innovation Solution
A device detection method where a reader monitors response signals from passive IoT devices during a detection session, allowing for role changes and timer/counter-based inheritance schemes among network elements to optimize the discovery process, reducing energy consumption and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reader transmits activation signals to passive IoT devices, then device detection capability is improved, but energy consumption and time consumption increase unpredictably
Solution Approach 1:
The patent implements dynamic role assignment where network elements can switch between activator and reader roles based on real-time detection needs. This dynamic adaptation allows the system to optimize energy consumption by having multiple elements share the activation signal transmission burden, rather than one element continuously consuming energy for detection.
Solution Approach 2:
The system establishes detection sessions in advance with pre-configured timer and counter parameters. By setting up the detection framework beforehand with inheritance schemes, the system avoids unpredictable energy consumption during actual detection, as the operational parameters are predetermined and optimized.
2Reliability
If activation signals are transmitted frequently to ensure device discovery, then detection reliability is improved, but time consumption increases
Solution Approach 1:
The patent implements periodic detection sessions with timer-based control, where activation signals are transmitted at optimized intervals rather than continuously or frequently. This periodic approach maintains detection reliability while reducing overall time consumption by eliminating redundant transmissions.
Solution Approach 2:
The system uses counter-based inheritance schemes that provide feedback on detection progress. When detection successes or failures are recorded, this feedback informs subsequent activation signal transmissions, optimizing the frequency and timing to achieve reliable discovery with minimal time loss.
3Reliability
If multiple network elements participate in detection sessions, then detection coverage is improved, but system complexity increases
Solution Approach 1:
The patent segments the detection function into distinct activator and reader roles that can be independently assigned to different network elements. This segmentation allows multiple elements to participate in detection coverage without proportionally increasing system complexity, as each element has a clearly defined, simplified role within the collaborative framework.
Solution Approach 2:
Network elements are designed with multi-functionality, capable of operating as either activators or readers depending on session requirements. This universality reduces system complexity by using standardized components for multiple roles, rather than requiring specialized elements for each function, while still achieving broad detection coverage.
4Loss of energy
If timer and counter parameters are configured for role inheritance, then energy efficiency is improved, but device complexity increases
Solution Approach 1:
The timer and counter parameters enable automatic role inheritance without requiring complex external control mechanisms. Network elements can autonomously determine role transitions based on these simple parameters, achieving energy efficiency through self-service operation while minimizing the complexity of control infrastructure needed.

AI summary
Example embodiments of the present disclosure relate to device detection session. An apparatus acting as a reader of a device detection session monitors a response signal from a device during the device detection session. The device is operable to be activated by an activation signal transmitted from a first device of the device detection session. The apparatus then causes a change in the device detection session based on the monitoring.
