Solution Overview

Problem

Conventional monitoring systems are difficult to move or reposition due to their permanent installation and reliance on hardwired power and communication links, limiting their flexibility and portability.

Innovation Solution

A low-power, wireless RF communications platform that allows sensor units to collect and relay data to a designated collector unit via wireless communication, enabling self-contained, portable operation and minimizing power consumption, with features like low-power standby mode and onboard storage for data when communication is disrupted.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If monitor devices are permanently installed and hardwired to power supply and communication links, then reliability of power and communication is improved, but portability and ease of repositioning deteriorate

Engineering Contradiction:

Improvepower supply reliabilityVSAvoidportability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces hardwired mechanical connections with wireless RF communication and battery-powered operation. Monitor devices communicate data wirelessly to the centralized device and are powered by portable power sources, eliminating the need for physical power and communication infrastructure at each monitoring location.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Stability of the object's composition

If monitor devices are permanently installed with hardwired connections, then stability of installation is improved, but adaptability to different locations deteriorates

Engineering Contradiction:

Improveinstallation stabilityVSAvoiddeployment flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent transforms the static, fixed installation model into a dynamic, mobile system. Monitor devices can be freely positioned and repositioned without permanent installation, adapting to different monitoring locations while maintaining operational stability through wireless connections and portable power.

Inventive Principle:

Principle #15Dynamics

3Productivity

If sensor units operate continuously in active mode, then data collection responsiveness is improved, but power consumption increases

Engineering Contradiction:

Improvedata collection responsivenessVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic wake-sleep cycles where sensor units alternate between low-power standby mode and active measurement/transmission modes. Sensors wake periodically to collect data and transmit information, then return to sleep mode, achieving balanced power consumption while maintaining monitoring capability.

Inventive Principle:

Principle #19Periodic action

AI summary

Wireless radio frequency communications platform may include a plurality of sensor units communicatively coupled over a wireless radio frequency communication network to a collector unit. The sensor units may be configured to collect data concerning monitored parameters and relay the collected data to a collector unit via a wireless radio frequency communication. The collector unit may be configured to receive and store the collected data received from the plurality of sensors and transmit the collected data to a computing device upon receiving an indication that the collector unit is communicatively coupled to the computing device. The computing device may execute a computer software application that facilitates communication between the computing device and collector unit.
