Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound wave payment technology uses hardware embedded in specific smartphones, then payment function is achieved, but compatibility with various terminals is limited
Solution Approach 1:
The patent introduces a sound wave conversion module as an intermediary component that converts magnetic field signals into sound wave signals. This module acts as a bridge between the magnetic field conversion device and the sound wave receiving module, enabling universal compatibility across different terminal types while maintaining reliable payment functionality.
Solution Approach 2:
The mobile terminal is designed with universal interfaces including a magnetic field conversion device and sound wave receiving module that can work with various terminal types (smartphones, tablets, wearables). The system supports multiple payment methods and can adapt to different offline payment infrastructures, achieving multi-functionality and broad terminal compatibility.
2Loss of information
If contactless communication with MST payment terminals is enabled in specific terminals, then data transmission is achieved, but service availability is limited to specific manufacturers
Solution Approach 1:
The sound wave conversion module serves as a universal intermediary that enables data transmission between the mobile terminal and various MST payment terminals regardless of manufacturer. By converting magnetic field signals to sound wave signals that can be received by the sound wave receiving module, the system achieves broad service availability across different terminal types.
Solution Approach 2:
The patent replaces the traditional mechanical contact-based payment interface with a sound wave-based communication system. This substitution eliminates manufacturer-specific hardware constraints and enables contactless data transmission across diverse terminal types, significantly improving service availability.
3Ease of manufacture
If offline infrastructures are not properly utilized, then mobile pay apps can be provided, but service convenience is reduced
Solution Approach 1:
The mobile terminal integrates multiple payment functions including sound wave payment, magnetic field conversion, and support for various offline payment infrastructures. This multi-functional design enables proper utilization of existing offline facilities while maintaining ease of service provision and operation.
Solution Approach 2:
The system enables self-service payment functionality by integrating the sound wave conversion module and magnetic field conversion device directly into the mobile terminal. Users can independently perform contactless payments at various offline terminals without requiring additional external equipment or complex setup procedures.
