Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual entry of credit card information using a remote control is used, then payment information can be entered, but it is inconvenient, time-consuming, and prone to errors

Engineering Contradiction:

Improveconvenience of payment information entryVSAvoidtime required for payment information entry

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical manual entry system (typing credit card information using a remote control) with an RFID-based wireless communication system. The RFID reader module in the media device automatically reads payment information from the RFID tag on the credit card through electromagnetic field coupling, eliminating the need for manual input and significantly reducing both time and user effort.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses RFID technology to create a wireless copy of the credit card information stored on an RFID tag. Instead of manually re-entering the information, the system reads the stored data from the RFID tag and transmits it wirelessly to the media device, enabling rapid and accurate payment information transfer without physical contact or manual typing.

Inventive Principle:

Principle #26Copying

2Reliability

If manual entry of credit card information is used, then payment can be processed, but error rates increase due to manual input

Engineering Contradiction:

Improveaccuracy of payment information entryVSAvoidsimplicity of payment information entry

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent eliminates manual typing operations by implementing an RFID-based automatic reading system. The RFID reader module automatically captures payment information from the RFID tag on the credit card, ensuring high accuracy by eliminating human errors associated with manual data entry while maintaining operational simplicity through contactless interaction.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service payment information transfer where the RFID tag on the credit card automatically provides its stored information when brought near the RFID reader. The process is self-executing and requires minimal user intervention beyond presenting the card, thereby improving both accuracy and ease of operation simultaneously.

Inventive Principle:

Principle #25Self-service

3Speed

If RFID reader module is always active, then payment information can be read quickly, but energy consumption increases

Engineering Contradiction:

Improvespeed of payment information transferVSAvoidenergy consumption of RFID reader module

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The RFID reader module operates periodically rather than continuously, activating only when needed for payment transactions. The system monitors for the presence of an RFID tag and triggers the reading operation at appropriate moments, thereby maintaining fast payment processing capability while significantly reducing overall energy consumption during idle periods.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The RFID reader module dynamically adjusts its operational state based on real-time conditions, switching between active and idle modes. When an RFID tag is detected or a payment transaction is initiated, the reader becomes active to quickly read information; otherwise, it remains in low-power mode, optimizing the balance between speed and energy consumption.

Inventive Principle:

Principle #15Dynamics
