Solution Overview

Problem

Telemetric devices monitoring asset contents or usage face challenges in maintaining battery life due to environmental exposure and the need for frequent battery replacements, especially when batteries are sealed within the device to maintain environmental protection.

Innovation Solution

Implementing a method where the telemetric device wakes up at fixed intervals to sample data and stores it until significant changes occur, transmitting only when changes exceed a predetermined threshold or after a prolonged period of no change, thereby minimizing battery drain and extending battery life.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the telemetric device transmits data continuously or at frequent intervals, then the data availability and monitoring accuracy are improved, but the battery power consumption increases and battery life decreases

Engineering Contradiction:

Improvedata availabilityVSAvoidbattery power consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The device implements periodic wake-up cycles where the processor wakes up at predetermined time intervals to check for data changes, compares current sensor data with historical data, and only transmits when changes exceed a threshold. This periodic action with conditional transmission reduces energy consumption while maintaining data availability for significant events.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts transmission parameters based on data change detection. When the difference between current and historical data exceeds a predetermined threshold, transmission occurs. This parameter-based decision-making optimizes the balance between data completeness and energy consumption.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If the device wakes up continuously to sample data, then the measurement accuracy and responsiveness are improved, but the battery drain increases

Engineering Contradiction:

Improvedata sampling accuracyVSAvoidbattery drain

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

The processor is configured to wake up at predetermined time intervals rather than continuously, sampling data only when necessary. This periodic sampling maintains measurement accuracy for significant changes while dramatically reducing battery drain compared to continuous monitoring.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses the sampled data itself to determine whether transmission is necessary by comparing current data with historical data. This self-service decision mechanism ensures that the device only expends transmission energy when actual changes occur, optimizing the balance between measurement accuracy and energy conservation.

Inventive Principle:

Principle #25Self-service

3Loss of information

If the device transmits all sampled data, then the data completeness is improved, but the transmission energy consumption and data processing load increase

Engineering Contradiction:

Improvedata completenessVSAvoidtransmission energy consumption

Core Design Contradiction:

Loss of informationVSUse of energy by stationary object

Solution Approach 1:

The system extracts only the essential information for transmission - specifically, data changes that exceed a predetermined threshold. By taking out only the significant data points rather than transmitting all sampled data, the system reduces transmission energy consumption while maintaining data completeness for meaningful events.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The device implements partial action by transmitting only the necessary data (changes exceeding threshold) rather than all sampled data. This partial transmission approach reduces energy consumption while providing sufficient information for effective monitoring and alerting.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method of operating a battery powered telemetric device configured with a processor, a sensor to measure data to indicate the contents or usage of a product within an asset generating sample data, data storage, at least one battery and a transmitter, includes keeping in the data storage at least one instance of previous data samples represented in a previously transmitted packet, awakening the telemetric device at variable time intervals programmed according to pre-determined user-defined characteristics so that the sensor provides sample data to the data storage to indicate the contents or usage of the product within the asset wherein the telemetric device is otherwise asleep to minimize battery drain, storing all the sample data since the transmission of the previously transmitted packet and the kept at least one instance of previous data samples represented in the previously transmitted packet in the data storage as all the stored sample data, transmitting a packet including representations of the contents or usage of the product within in the asset of all the stored sample data in a manner to limit the number of transmissions to as few as possible unless: the stored sample data indicates changes in the contents or usage of the product within the asset are equal to or exceed a predetermined change value; or there has been no change in the contents or usage of the product within the asset over a prolonged period of time.
