Sensor Device Placement via Proximity and Load Stimulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Advanced lighting control systems are not widely adopted in the commercial market due to high installation and setup costs, and existing methods for configuring sensor devices on a structure's floor plan are not secure or reliable, allowing non-structure devices to be mistakenly placed.
Innovation Solution
A method and system that use a mobile computing device to communicate with fixed sensor units via a communication channel, stimulating their sensors to identify and place devices on a floor plan based on proximity-dependent information, including loading a power metering device with a specific load to enhance device identification and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods are used to place devices on the floor plan, then device placement is simple, but reliability and security are poor allowing non-structure devices to be mistakenly placed
Solution Approach 1:
The system performs preliminary actions by stimulating sensors and loading power metering devices with specific loads before final device placement. This pre-verification process ensures that only devices belonging to the structure are placed, improving reliability while maintaining a manageable configuration process through automated guidance.
Solution Approach 2:
The system implements feedback mechanisms where sensor devices communicate device identifiers and proximity-dependent information back to the mobile computing device. This feedback loop enables verification of device authenticity and accurate placement on the floor plan, enhancing both reliability and security without significantly increasing complexity.
2Measurement precision
If sensor devices are stimulated and power metering devices are loaded with specific loads for identification, then device identification accuracy improves, but installation and setup costs increase
Solution Approach 1:
The system enables self-service by allowing the mobile computing device to automatically stimulate sensors and load power metering devices during the configuration process. This automated approach improves identification accuracy while reducing the need for expensive manual installation and setup, as the system guides users through the process without requiring specialized expertise.
3Manufacturing precision
If proximity dependent information is used to estimate device location, then placement accuracy improves, but additional triggers and sensors increase system complexity
Solution Approach 1:
The system applies multi-functionality by using existing sensor devices to provide multiple functions: detection, identification, and proximity measurement. The same sensors that detect device presence also provide proximity-dependent information for location estimation, eliminating the need for separate components and reducing overall system complexity while maintaining high placement accuracy.
