Solution Overview

Problem

Existing solutions fail to effectively preserve battery power and prevent electronic circuits from becoming non-operational due to battery depletion, leading to limited lifespan and operational failures.

Innovation Solution

A system and method that utilize a container with a beacon to determine item location and battery status, cluster items based on location, and designate a master item with higher battery charge to sense parameters, reducing power consumption by minimizing communication among items.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all items continuously communicate with the server to report their status, then the server can maintain real-time monitoring of all items, but the battery power of each item is depleted quickly

Engineering Contradiction:
Improvereal-time monitoring capabilityVSAvoidbattery power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Multiple items are grouped into clusters where they share a common master item. The cluster master represents the entire cluster to the server, consolidating multiple communication tasks into a single communication channel. This merging reduces the total number of communications from N items to N/cluster_size masters, significantly reducing power consumption while maintaining monitoring coverage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cluster master item acts as an intermediary between the server and other items in the cluster. Instead of direct communication between the server and each item, the master receives server commands and transmits sensed parameters from other items to the server. This intermediary role reduces communication frequency for individual items, extending their battery life.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If each item independently senses and transmits parameters, then complete data collection is achieved, but communication overhead and power consumption increase significantly

Engineering Contradiction:
Improveparameter data completenessVSAvoidcommunication energy
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent merges the sensing and transmission functions of multiple items into a single cluster master. The master item collects sensed parameters from other items in the cluster and transmits them to the server in consolidated messages. This ensures complete data collection while reducing communication energy expenditure by eliminating redundant transmissions from each individual item.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cluster master item performs multiple functions: it senses parameters itself, collects parameters from other cluster members, processes the data, and communicates with the server. This multi-functional approach consolidates what would otherwise require separate operations from each item, reducing overall system energy consumption while maintaining data completeness.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Use of energy by moving object

If items form clusters to reduce communication, then power consumption decreases, but the system complexity increases due to cluster management

Engineering Contradiction:
Improvepower consumptionVSAvoidcluster management complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

Items automatically perform clustering operations based on their sensed parameters and battery status without requiring manual configuration. The system self-organizes into clusters, automatically selecting masters and establishing communication protocols. This self-service approach reduces the operational complexity burden on users while maintaining the power-saving benefits of clustering.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms where items continuously report their status to the server, which then provides instructions for cluster formation and master selection. This feedback loop allows the system to dynamically adjust cluster configurations based on current conditions, managing complexity through automated control rather than static pre-configuration.

Inventive Principle:
Principle #23Feedback

4Duration of action of moving object

If the system selects a master item with highest battery charge, then power distribution is optimized, but the selection process requires additional communication overhead

Engineering Contradiction:
Improvebattery life extensionVSAvoidmaster selection time
Core Design Contradiction:
Duration of action of moving objectVSLoss of time

Solution Approach 1:

Items report their battery status to the server in advance of cluster formation. The server uses this pre-collected information to identify suitable master candidates without requiring additional real-time communication rounds. This preliminary data collection allows the server to make informed master selections efficiently, extending battery life while minimizing time loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous monitoring of battery status as part of normal operation, so the information needed for master selection is already available when clustering is needed. This continuous action ensures that master selection can occur immediately without requiring separate data gathering phases, optimizing both battery life extension and time efficiency.

Inventive Principle:
Principle #20Continuity of useful action
