Portable Device Network Access via Connectivity Service Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable devices face battery drain and limited service access due to the need to activate multiple connectivity modules to discover services in a network, resulting in a poor user experience.
Innovation Solution
A portable device with a transceiver supporting multiple communication protocols connects to a connectivity service device to retrieve a service list, determining the most appropriate service for communication, thereby reducing power consumption by using low-power connections and selective module activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple connectivity modules are activated to discover services, then service discovery capability is improved, but battery power consumption increases
Solution Approach 1:
A connectivity service device is introduced as an intermediary that maintains a service list of available services in the network. The portable device queries this service list through a low-power connection, eliminating the need to activate multiple connectivity modules for service discovery. This mediator approach resolves the contradiction by centralizing service information and allowing low-power access.
2Adaptability or versatility
If multiple connectivity modules are activated to discover services, then service discovery capability is improved, but user experience deteriorates due to short battery life
Solution Approach 1:
The connectivity service device acts as a mediator that provides service information through a low-power connection interface. This allows the portable device to discover services without activating multiple high-power connectivity modules, thereby extending battery life and improving user experience while maintaining service discovery capability.
Solution Approach 2:
The service list is pre-maintained by the connectivity service device, containing information about available services in the network. The portable device can query this pre-prepared list without needing to perform exhaustive service discovery scans, thus reducing power consumption and improving user experience.
3Adaptability or versatility
If all connectivity modules are activated, then service access capability is improved, but device complexity and power consumption increase
Solution Approach 1:
The connectivity service device serves as a mediator that manages service information centrally. The portable device only needs to maintain a low-power connection to this service device to access service lists, significantly reducing the complexity of configuring and managing multiple connectivity modules while preserving service access capability.
