Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If motion sensors and adaptive broadcast profiles are implemented in container nodes, then positional awareness and tracking accuracy are improved, but device complexity and energy consumption increase

Engineering Contradiction:
Improvepositional awarenessVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system dynamically adjusts the broadcast profile parameters (broadcast interval, transmission power) based on the detected motion status of the container. When motion is detected, the system switches to a profile with shorter intervals and higher power to maintain accurate tracking, and when stationary, it uses longer intervals and lower power to conserve energy.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes operational parameters (broadcast interval, transmission power) of the container node based on motion detection. This allows the system to adapt measurement precision and energy consumption by adjusting these parameters dynamically rather than maintaining fixed settings.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If broadcast interval is decreased and transmission power is increased for accurate tracking, then positional awareness is improved, but energy consumption increases

Engineering Contradiction:
Improvepositional awarenessVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system transitions between different broadcast profiles dynamically based on container motion status. The motion status detector triggers switching between a first profile (shorter interval, higher power) for moving containers and a second profile (longer interval, lower power) for stationary containers, optimizing energy usage while maintaining tracking accuracy when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses periodic broadcast intervals that are adaptively adjusted based on motion detection. Instead of continuous high-power broadcasting, the system employs periodic broadcasts with variable intervals, reducing overall energy consumption while maintaining positional awareness during motion events.

Inventive Principle:
Principle #19Periodic action

3Area of stationary object

If multiple container nodes operate in dense environments, then tracking coverage is improved, but communication congestion increases

Engineering Contradiction:
Improvetracking coverageVSAvoidcommunication congestion
Core Design Contradiction:
Area of stationary objectVSLoss of information

Solution Approach 1:

Each container node adapts its broadcast characteristics (interval and power) based on local conditions detected by its motion sensor. This localized adaptation allows nodes in dense environments to adjust their communication behavior independently, reducing overall congestion while maintaining adequate tracking coverage across the entire area.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system enables dynamic adjustment of broadcast profiles for each container node based on its motion status. In dense environments, stationary nodes can use longer intervals to reduce traffic, while moving nodes use shorter intervals for accurate tracking, optimizing the balance between coverage and congestion.

Inventive Principle:
Principle #15Dynamics

AI summary

Motion-based management of a logistics container uses elements of a wireless node network including a container node associated with the logistics container and equipped with a motion sensor. The motion sensor detects a motion status (e.g., moving, stationary, accelerating, decelerating) for the logistics container. The container node compares the motion status to a prior motion status, and then identifies a changed motion condition for the logistics container based upon the comparison. In response to the changed motion condition, the container node alters a broadcast profile used by the container node in communicating with other nodes in the wireless node network. The container node may be deployed as an apparatus within a logistics container, be considered together with the logistics container as a motion sensing container node apparatus, and be considered with multiple package ID nodes as a motion-based management system for the logistics container.
