Solution Overview

Problem

Existing franking machines lack support for multiple data transmission methods, including both wireless and wired connections, and suffer from single-point failure vulnerabilities and inefficient energy use due to non-dynamic component detection.

Innovation Solution

A material processing device, such as a franking machine, is equipped with at least two separate communication modules, each supporting different transmission methods, with a control unit to detect and manage their operation and redundancy, optimizing placement and enabling flexible configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple communication modules are integrated into the franking machine, then communication reliability and flexibility are improved, but device complexity increases

Engineering Contradiction:
Improvecommunication reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The communication system is segmented into multiple independent communication modules (first communication module and second communication module), each capable of operating autonomously through different transmission methods. This segmentation allows the system to maintain communication reliability by having fallback options while keeping each module's complexity manageable and independent.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control unit is designed with universal functionality to control both the first and second communication modules, detecting their operational status and selecting appropriate transmission methods. This multi-functionality approach allows a single control unit to manage diverse communication protocols without requiring separate control logic for each module, thus improving reliability while limiting the increase in overall device complexity.

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

2Device complexity

If a single communication module is used, then device complexity is reduced, but the system becomes vulnerable to single-point failures

Engineering Contradiction:
Improvedevice complexityVSAvoidcommunication reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system implements beforehand cushioning by integrating a second communication module as a backup redundancy against the potential failure of the first communication module. The control unit is pre-configured to detect failures and automatically switch to alternative transmission methods, providing prior protection against communication breakdowns without requiring complex real-time decision-making during failure events.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If all communication modules operate continuously, then communication availability is maximized, but energy consumption increases

Engineering Contradiction:
Improvecommunication availabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The control unit implements dynamic control by continuously monitoring the operational status of both communication modules and adapting the transmission method in real-time. This dynamic approach allows the system to activate only the necessary communication modules based on current conditions, maintaining communication availability while optimizing energy consumption by avoiding continuous operation of all modules regardless of need.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control unit performs self-service by autonomously detecting the operational status of communication modules and selecting appropriate transmission methods without external intervention. This self-monitoring and self-adjusting capability ensures communication availability while minimizing energy consumption through intelligent, autonomous decision-making about module activation.

Inventive Principle:
Principle #25Self-service
