Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual ticketing processes are used by conductors, then human oversight and flexibility are maintained, but human error and inefficiency increase

Engineering Contradiction:

Improveaccuracy of seat verificationVSAvoidefficiency of ticketing operations

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system enables self-service ticket verification where the passenger's mobile device automatically communicates with the conductor's device via wireless signals. The device independently performs seat verification and destination tracking without requiring manual conductor intervention, thereby improving both accuracy and efficiency simultaneously

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical manual verification process with an automated electronic system using wireless communications (UWB, Bluetooth, WiFi). The conductor's device automatically receives and processes signal data from the passenger's device, eliminating manual error-prone operations while maintaining oversight capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If automated positional tracking is implemented using wireless signals, then efficiency and accuracy are improved, but system complexity increases

Engineering Contradiction:

Improveautomation of verification processVSAvoidcomplexity of ticketing system

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system uses universal wireless communication protocols (UWB, Bluetooth, WiFi) that are already integrated into modern mobile devices. This allows the ticketing system to leverage existing multi-functional hardware capabilities rather than requiring specialized dedicated equipment, thereby reducing overall system complexity while maintaining automation

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The conductor's device serves as an intermediary that simplifies the interaction between the passenger's device and the central system. It receives wireless signals, processes the data locally, and communicates with the server, thereby reducing the computational burden on individual devices and simplifying the overall system architecture

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If real-time monitoring of passenger location is performed, then destination tracking accuracy is improved, but energy consumption increases

Engineering Contradiction:

Improveprecision of destination trackingVSAvoidenergy consumption of wireless signals

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

Instead of continuous real-time monitoring, the system uses periodic wireless signal exchanges triggered by specific events such as conductor inspections or scheduled checkpoints. This periodic operation maintains destination tracking precision while significantly reducing energy consumption compared to continuous monitoring

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system implements partial monitoring by focusing measurement efforts only when necessary (during conductor device interactions or at critical journey points) rather than continuously. This selective approach maintains sufficient tracking precision for ticket validation while minimizing energy expenditure on wireless communications

Inventive Principle:

Principle #16Partial or excessive action
