Mobile Controller Tag Reader Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for remotely controlling controllable devices, such as smart light bulbs, are not well-suited for individual user control and do not effectively manage access conflicts between multiple users.
Innovation Solution
A system comprising a mobile controller with a tag reader and an access control module that uses a first wireless channel for connecting to an electronic tag and a second wireless channel to send digital commands to the controllable device, with access control based on a control period starting upon connection and terminating when a control release condition is met, such as location or time parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart light bulb with receiver and processor is used for remote control, then the device can respond to control signals from external devices, but the system is not well suited for control by individual users and cannot effectively manage access conflicts between multiple users
Solution Approach 1:
The patent introduces an electronic tag as an intermediary device that mediates between the mobile controller and the controllable device. The tag stores identification information and control parameters, acting as a physical key that enables or disables control access. This intermediary resolves the contradiction by providing a simple proximity-based access mechanism without requiring complex authentication systems in the controllable device itself.
Solution Approach 2:
The system performs preliminary action by pre-storing control authorization information in the electronic tag before the control operation occurs. The tag contains identification information and control parameters that are read in advance when the mobile controller approaches the controllable device. This eliminates the need for real-time complex authentication, enabling individual user control while maintaining simple device architecture.
2Adaptability or versatility
If multiple users can control the same controllable device, then user flexibility is improved, but access conflicts between users cannot be effectively resolved
Solution Approach 1:
The patent implements dynamic control access by making the control period adjustable and configurable. The electronic tag stores a control period parameter that determines how long a user maintains control after proximity detection. This dynamic timing mechanism resolves access conflicts automatically - when a new user approaches, the system can extend or reset the control period, ensuring that control transitions are smooth and conflicts are resolved without requiring complex user negotiation or arbitration protocols.
3Ease of operation
If control is allowed from any location, then user convenience is improved, but users not in close proximity can issue control commands which is often not desired
Solution Approach 1:
The patent applies local quality by making control authorization location-dependent through the electronic tag's proximity detection capability. The system reads identification information from the tag only when the mobile controller is in close proximity to the controllable device. This creates a localized control zone around each device, ensuring that only users physically near the device can control it, while still allowing remote operation within that zone. The control parameters stored in the tag can be customized for different locations and devices.
