Solution Overview

Problem

Conventional technologies fail to manage bandwidth efficiently among multiple wireless devices due to lack of awareness of overlapping communication intervals and differing data priorities, leading to congestion and wasted bandwidth.

Innovation Solution

An arbiter device determines a network messaging schedule based on the capabilities of multiple streams, adjusting communication intervals to minimize overlaps and prioritize data types, thereby optimizing bandwidth allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional technologies are used for managing bandwidth among multiple wireless devices, then device compatibility and ease of operation are maintained, but bandwidth efficiency deteriorates due to overlapping communication intervals and lack of awareness of other streams

Engineering Contradiction:

Improvebandwidth efficiencyVSAvoidscheduling system complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The arbiter device serves as an intermediary that receives capability information from multiple streams, determines an optimized network messaging schedule, and communicates it back to the streams. This mediator coordinates communication intervals to prevent overlaps and improve bandwidth efficiency without requiring complex peer-to-peer negotiation between streams.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary determination of the network messaging schedule based on stream capabilities before actual data transmission begins. By pre-configuring communication intervals and priorities, the system avoids overlapping transmissions and eliminates the need for reactive conflict resolution during data transfer.

Inventive Principle:

Principle #10Preliminary action

2Loss of energy

If communication intervals are increased to reduce overlaps, then bandwidth efficiency improves, but communication speed and data throughput deteriorate

Engineering Contradiction:

Improvebandwidth wasteVSAvoidcommunication speed

Core Design Contradiction:

Loss of energyVSSpeed

Solution Approach 1:

The system applies different communication interval configurations to different streams based on their specific capabilities and data priorities. High-priority streams with strict latency requirements receive shorter intervals, while lower-priority streams are assigned longer intervals, optimizing overall bandwidth utilization without sacrificing the speed requirements of critical data.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The network messaging schedule is dynamically determined based on the capabilities and priorities of active streams. The arbiter device can adjust communication intervals in real-time as streams are opened or closed, ensuring optimal bandwidth efficiency while maintaining appropriate communication speeds for each active stream's requirements.

Inventive Principle:

Principle #15Dynamics

3Reliability

If stream-aware scheduling is implemented to prioritize critical data, then data reliability improves, but system complexity and difficulty of detecting and measuring capabilities increase

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The arbiter device collects capability information from streams in advance before determining the network messaging schedule. This preliminary capability detection includes information about data types, latency requirements, and bandwidth needs, allowing the system to establish reliable prioritization rules before actual data transmission begins.

Inventive Principle:

Principle #10Preliminary action

4Productivity

If communication intervals are reduced to increase throughput, then productivity improves, but the likelihood of overlapping transmissions and bandwidth conflicts increases

Engineering Contradiction:

Improvedata throughputVSAvoidtransmission conflict frequency

Core Design Contradiction:

Solution Approach 1:

The arbiter device acts as a central coordinator that assigns specific time intervals to different streams, ensuring that even with reduced intervals for higher throughput, no two streams transmit simultaneously. This mediation maintains high productivity while eliminating transmission conflicts through centralized schedule management.

Inventive Principle:

Principle #24Intermediary (Mediator)
