Solution Overview

Problem

Current wireless communication systems require separate protocols for connection-oriented and connectionless data transfer, leading to increased program and circuit sizes, power consumption, and complex protocol procedures, which is inefficient especially in high-speed applications like automatic ticket gates.

Innovation Solution

A wireless communication device and method that enables both connection-oriented and connectionless protocols to be achieved using a single protocol by incorporating a controller that executes connectionless data transfer using a portion of the connection-oriented protocol, allowing data to be transmitted during the connection establishment procedure, thereby reducing the time required for communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate protocols are implemented for connection-oriented and connectionless data transfer, then both protocols can achieve their respective functions, but program and circuit sizes increase, power consumption increases, and protocol procedures become complex

Engineering Contradiction:
Improveprotocol functionalityVSAvoidprogram and circuit sizes
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a single protocol that can function as both connection-oriented and connectionless protocols. The controller selectively executes different procedures based on the communication mode: connection establishment procedures when connection-oriented mode is detected, or direct data transfer procedures when connectionless mode is detected. This multi-functional design eliminates the need for separate protocols, reducing program size and complexity while maintaining both protocol functionalities.

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

Solution Approach 2:

The patent merges the connection-oriented and connectionless protocols into a unified protocol structure. The frame generator generates frames that can be used in both modes, and the controller integrates the decision-making logic to select between connection establishment and direct data transfer. This merging reduces the overall system complexity and resource requirements compared to maintaining separate protocol implementations.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If separate protocols are implemented for connection-oriented and connectionless data transfer, then both protocols can achieve their respective functions, but power consumption increases

Engineering Contradiction:
Improveprotocol functionalityVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

By implementing a single multi-functional protocol, the system reduces the active processing requirements compared to maintaining and switching between separate protocols. The controller efficiently selects the appropriate procedure (connection establishment or direct data transfer) based on the communication mode, reducing unnecessary protocol overhead and power consumption while maintaining full functionality for both connection-oriented and connectionless operations.

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

3Adaptability or versatility

If separate protocols are implemented for connection-oriented and connectionless data transfer, then both protocols can achieve their respective functions, but protocol procedures become complex

Engineering Contradiction:
Improveprotocol functionalityVSAvoidprotocol procedures
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the protocol procedures into distinct functional blocks: connection establishment procedures for connection-oriented mode and direct data transfer procedures for connectionless mode. The controller manages these segmented procedures through selective execution based on the communication mode, simplifying the overall protocol implementation compared to handling all procedures within a single complex protocol framework.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The unified protocol uses a common frame structure and controller logic that handles both connection-oriented and connectionless operations. This universality simplifies protocol procedures by eliminating the need for separate protocol stacks, reducing the complexity of protocol management while maintaining the ability to perform both types of data transfer.

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

4Reliability

If connection establishment procedure is completed fully, then reliable connection is established, but time required for communication increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidcommunication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements a dynamic communication approach where the controller adapts the connection establishment procedure based on the communication mode and requirements. In connection-oriented mode, the full connection establishment procedure is executed to ensure reliability. In connectionless mode, the system skips intermediate steps and proceeds directly to data transfer, reducing communication time while maintaining acceptable reliability levels appropriate for the specific application scenario.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies partial action by executing only the necessary portions of the connection establishment procedure based on the communication mode. When connectionless mode is detected, the system performs minimal setup actions and proceeds directly to data transfer, avoiding unnecessary time-consuming steps while still achieving the communication objective with sufficient reliability for the application context.

Inventive Principle:
Principle #16Partial or excessive action
