Solution Overview

Problem

Existing ultra-wideband transceiver systems for managing mobile communication entities lack flexibility and efficiency in determining device proximity and access permissions, leading to suboptimal access control and communication session management.

Innovation Solution

An ultra-wideband transceiver device with an electronic circuit and data store that receives transmissions from mobile devices, determines device proximity, and maintains an inventory list for authorized devices, prioritizing communication sessions based on proximity and access permissions, using cryptographic authentication and secure communication protocols.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the transceiver maintains an inventory list of all detected mobile communication devices, then the system achieves comprehensive device tracking, but the data store becomes inefficient and access control becomes less secure due to inclusion of unauthorized devices

Engineering Contradiction:

Improveaccess control securityVSAvoidinventory list size

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary and relevant mobile communication devices from the complete set of detected devices by implementing zone boundary checks and access permission verification. The electronic circuit determines whether each device is within a defined zone boundary and whether it has access permission before storing an entry in the inventory list, thereby removing unauthorized or irrelevant devices from the data structure.

Inventive Principle:

Principle #2Taking out (Extraction)

2Adaptability or versatility

If the transceiver establishes communication sessions with all devices in range, then the system achieves maximum connectivity, but the system performance deteriorates due to processing overhead and energy consumption

Engineering Contradiction:

Improvecommunication connectivityVSAvoidsystem processing efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent performs preliminary filtering actions before establishing communication sessions. The electronic circuit first determines whether a mobile communication device is within the defined zone boundary and whether it has access permission stored in the inventory list. Only after these preliminary checks pass does the system proceed to establish communication sessions, avoiding unnecessary processing for unauthorized or out-of-zone devices.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If the transceiver monitors all mobile devices continuously, then the system achieves complete surveillance capability, but the energy consumption increases significantly

Engineering Contradiction:

Improvedevice position monitoring accuracyVSAvoidtransceiver power consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies local quality by focusing monitoring resources only on the specific region of interest (the defined zone boundary) rather than uniformly monitoring all devices in all directions. The electronic circuit determines zone boundary conditions and access permissions only for devices that fall within the monitored zone, thereby reducing unnecessary energy expenditure on devices outside the area of interest.

Inventive Principle:

Principle #3Local quality
